The Dawn of Sovereign Digital Money

The financial world stands at the cusp of a significant transformation, driven by the accelerating digitization of money. At the forefront of this evolution are Central Bank Digital Currencies (CBDCs) – a new form of sovereign money that promises to redefine how we transact, save, and interact with the financial system. For investors, financial professionals, and indeed anyone with a stake in the economy, understanding the implications of CBDCs, particularly for the banking sector, is no longer optional; it’s essential.

What are CBDCs? A Quick Primer for the Modern Investor

A Central Bank Digital Currency is a digital form of a country’s fiat currency, issued and backed by the nation’s central bank. Unlike physical banknotes and coins, CBDCs exist purely in a digital format. Crucially, a CBDC represents a direct liability of the central bank itself. This distinguishes it fundamentally from the digital money currently held in commercial bank accounts, which is a liability of the commercial bank, not the central bank.

CBDCs are also distinct from the array of private digital currencies that have emerged. They are not cryptocurrencies like Bitcoin, which are typically decentralized, operate on permissionless blockchains, and are not backed by any central authority, often exhibiting high volatility. They also differ from stablecoins, which are privately issued digital tokens that aim to maintain a stable value, often by pegging themselves to a fiat currency or other assets. While stablecoins seek stability, they still carry risks related to the issuer and the quality of their reserves.

The key distinction is that CBDCs carry the full faith and credit of the government, making them a risk-free form of digital currency from a credit and liquidity perspective, much like physical cash. This inherent safety and sovereign backing is a core characteristic that underpins many of their potential impacts on the existing financial architecture.

The Global Pulse: CBDCs are No Longer Theoretical

What might have seemed like a niche academic concept a few years ago has rapidly moved into the realm of active policy and development. As of early 2025, an overwhelming 134 countries and currency unions, collectively representing 98% of global Gross Domestic Product (GDP), are in various stages of exploring, developing, or piloting CBDCs. This marks a dramatic surge from just 35 countries in May 2020.

Major economic blocs and nations are deeply involved. China’s digital yuan (e-CNY) is the largest retail CBDC pilot globally, with transaction volumes reaching $986 billion by June 2024 and active use in diverse sectors like education and healthcare. The Eurozone is advancing its Digital Euro project, currently in a preparation phase focused on rulebook finalization and technical development. India has launched its Digital Rupee pilot, and even the United States, while cautious about a retail CBDC, is participating in significant cross-border wholesale CBDC initiatives like Project Agorá.

Furthermore, several nations, including the Bahamas (Sand Dollar), Jamaica (Jam-Dex), and Nigeria (e-Naira), have already fully launched their retail CBDCs. While adoption in these early instances has faced hurdles, the commitment to sovereign digital currency is clear.

The sheer scale and breadth of this global exploration underscore a fundamental shift. Central banks are not merely experimenting; they are actively preparing for a future where digital sovereign currency plays a significant role. This makes the potential impact of CBDCs on the banking system an immediate and critical area of focus for anyone involved in finance and investment.

Why Banks (and You) Need to Pay Attention

The advent of CBDCs is far more than just the introduction of a new payment method. It carries the potential to fundamentally alter the structure, operations, profitability, and competitive dynamics of the traditional banking system. For commercial banks, CBDCs could reshape their core functions, from deposit-taking and lending to payment processing and customer relationships. For investors, these changes will create new risks and opportunities within the financial sector. Understanding these shifts is paramount to navigating the evolving financial landscape.

This foundational understanding is crucial as we explore their transformative impact on the banking industry, where the very nature of a CBDC as a central bank liability underpins many of the anticipated changes.

 7 Key Ways CBDCs Could Reshape the Banking Landscape

The introduction of Central Bank Digital Currencies is not merely a technological upgrade but a potential paradigm shift for the banking sector. The following seven areas highlight the most significant ways CBDCs could alter the traditional roles, operations, and environment of banks.

1. Reshaping Bank Deposits and Funding Structures

One of the most debated impacts of CBDCs revolves around their potential to alter the fundamental deposit-taking role of commercial banks.

• The Core Change: A New Home for Digital Cash?
  Retail CBDCs, by their very nature as a direct liability of the central bank, would offer the public a digital, risk-free alternative to holding deposits at commercial banks. This could incentivize individuals and businesses to shift a portion of their funds from traditional bank accounts into CBDC wallets or accounts. This potential migration of funds is widely referred to as bank disintermediation.2
  The significance of this lies in the traditional banking model. Commercial banks heavily rely on customer deposits as a primary, relatively cheap, and stable source of funding for their lending activities and other investments. A substantial outflow of these deposits to CBDCs could shrink commercial banks’ balance sheets. Consequently, banks might face increased funding costs if they are forced to turn to more expensive and potentially less stable sources of funding, such as wholesale markets. This shift could have profound implications for the fractional reserve banking system, where banks hold only a fraction of their deposit liabilities in liquid reserves and lend out the rest. A review by the Federal Reserve acknowledges that if households and nonfinancial businesses move deposits to CBDCs, bank balance sheets would contract, potentially leading to a reduction in the availability of bank credit.
• Not So Fast: Mitigating Factors and Design Choices
  Central banks are acutely aware of the risks of widespread disintermediation and are actively considering design features to manage its scale and pace. These mitigants are crucial for maintaining financial stability:
  • Holding Limits: Many CBDC proposals include caps on the amount of CBDC an individual or entity can hold. For instance, the Bank of England has discussed such limits, and the European Central Bank (ECB) has explored a potential holding limit of around €3,000 per person for the digital euro. These limits are intended to position CBDCs more as a means of payment rather than a significant store of value that could draw massive funds away from banks.
  • Remuneration Policy: The interest rate paid on CBDC holdings (if any) is a critical design lever. Most proposals lean towards CBDCs being non-interest-bearing or offering very low or tiered interest rates. This would make them less attractive for large-scale savings compared to potentially interest-bearing commercial bank deposits, reinforcing their role as a cash-like digital instrument for transactions. An unremunerated CBDC would be more akin to digital cash.

The actual extent of disintermediation will also depend on the competitive responses of commercial banks. They might be spurred to offer more attractive interest rates on deposits or enhance their service offerings to retain customers. Some economic models suggest that in banking sectors with significant market power, an interest-bearing CBDC could paradoxically lead to an increase in bank deposits by compelling banks to compete more vigorously for them. Furthermore, the way a central bank decides to “recycle” the CBDC liabilities back into the financial system—for example, by lending these funds back to commercial banks or by purchasing assets—will be a key determinant of the net impact on bank funding and overall financial stability.Even with measures like holding limits, the introduction of CBDCs could lead to a notable shift in the composition and stability of bank deposits. Banks might see a flight of highly liquid, transactional balances, leaving them with a deposit base that is “stickier” but potentially more expensive to maintain. This could also push banks towards greater reliance on wholesale funding, which is often more volatile and costly than retail deposits. Such changes would inevitably affect banks’ liquidity and funding ratios, such as the Liquidity Coverage Ratio (LCR) and Net Stable Funding Ratio (NSFR), necessitating adjustments in their asset-liability management strategies. This represents a more nuanced impact than a simple reduction in total deposits.Moreover, the existence of CBDCs as an ultra-safe, direct liability of the central bank could redefine the “flight to safety” dynamic during financial crises. The ease and speed with which funds could be digitally transferred from commercial bank deposits to CBDCs might accelerate bank runs in times of panic, even if holding limits are in place. The psychological allure of a perfectly safe digital alternative during periods of systemic stress could be substantial, potentially requiring a re-evaluation of existing deposit insurance schemes and central bank emergency liquidity provision mechanisms. Banks could face intensified scrutiny of their liquidity buffers and crisis preparedness protocols.Finally, the specific design of a retail CBDC will influence which segments of the “digital cash” market it competes in. A non-interest-bearing CBDC with strong privacy features might primarily serve as a substitute for physical cash in small, everyday transactions. Conversely, an interest-bearing CBDC, even with low rates, or one offering superior convenience for certain transactions, could compete more directly with transactional bank accounts. This suggests that banks may need to develop differentiated strategies. They might focus on adding significant value to their transactional accounts to retain customer loyalty, while perhaps conceding a share of very small, cash-like balances to CBDCs. This points towards a more complex and segmented competitive landscape rather than a uniform disintermediation across all types of bank deposits.

2. Altering Bank Profitability and Lending Dynamics

The potential shifts in bank funding structures due to CBDCs will inevitably ripple through to bank profitability and their capacity to lend.

• The Squeeze on Margins
  A primary concern for banks is the potential compression of their Net Interest Margins (NIMs). NIM, the difference between the interest income banks generate and the interest they pay out on deposits, is a cornerstone of traditional bank profitability. If CBDCs, as a new, safe, and potentially low-cost payment alternative, intensify competition for customer deposits, commercial banks may be forced to offer higher interest rates on their own deposit products to retain funds. This would directly eat into their NIMs.
  Similarly, if banks experience a significant outflow of low-cost retail deposits and have to replace this funding with more expensive wholesale market funds, their overall funding costs will rise, further squeezing margins. The International Monetary Fund (IMF) has noted that CBDCs can “increase competition for deposit funding, raise banks’ share of wholesale funding, and lower bank profits”.
• Impact on Lending Capacity and Cost
  A reduction in the volume of available deposits or an increase in their cost can directly constrain a bank’s ability to extend credit or may lead to an increase in the cost of borrowing for individuals and businesses. Several studies suggest that if CBDC introduction results in a significant contraction of bank balance sheets due to deposit outflows, there could be an associated reduction in the overall availability of bank credit.25
  However, the picture is not entirely one-sided. The European Central Bank (ECB) research points out that CBDC issuance might also generate a “fiscal expansion effect.” This could occur if the central bank earns more income from an expanded balance sheet (due to CBDC issuance) and remits higher profits to the government, which could then translate into lower taxes or increased government spending, potentially stimulating economic activity and, indirectly, lending. The overall net impact on bank lending would therefore depend on the interplay and relative magnitudes of the disintermediation effect and this potential fiscal expansion effect.
• Access to Transaction Data – A Shifting Landscape
  Commercial banks currently benefit from extensive access to customer transaction data. This data is a valuable asset, used for credit risk assessment, developing new financial products, personalizing services, and targeted marketing. The introduction of CBDCs could alter this data landscape significantly.
  If CBDC transactions are primarily intermediated by a diverse range of Payment Interface Providers (PIPs), or if certain CBDC designs offer enhanced anonymity or pseudonymity for users, commercial banks’ direct and comprehensive visibility into their customers’ full spectrum of financial activities might be reduced or become more fragmented. One analysis notes that the broader financial sector could lose access to the rich data that comes from processing transactions, with the government or central bank potentially becoming the primary holder of aggregated or anonymized CBDC transaction data. This shift could particularly impact FinTech companies whose business models rely heavily on accessing and monetizing such payment data.
  These direct impacts on margins, lending, and data access could catalyze deeper, structural changes in how banks operate and compete. One potential long-term consequence is a bifurcation of bank business models. Institutions heavily reliant on traditional net interest income derived from a large, stable base of retail deposits might face significant pressure, potentially requiring radical transformation or consolidation. Conversely, banks with already strong fee-based income streams—such as those from wealth management, investment advisory, or specialized corporate lending—or those agile enough to develop new services around the emerging CBDC infrastructure might find new avenues for growth. This could lead to a divergence in the banking sector: some institutions might evolve into more “utility-like” providers, facilitating basic access to CBDCs and related payment services with thinner margins, while others could transform into highly specialized financial service firms focusing on value-added offerings. Such a shift could also fuel merger and acquisition activity as banks seek to adapt their business models to this new reality.
  Another development could be the rise of “data consenting” as a distinct service. If banks’ automatic and comprehensive access to transaction data diminishes, the ability to obtain explicit customer consent for data usage will become even more critical and potentially more valuable. Banks, or new FinTech entrants, could develop services that empower customers to manage their CBDC-related financial data, grant consent for its use for specific purposes (like loan applications or personalized financial advice), and perhaps even enable customers to share or monetize their own data under controlled conditions. This could open up new revenue streams for institutions focusing on data management, privacy-enhancing advisory services, and customer empowerment, moving from a model of passively collecting data to one of actively helping customers leverage their financial data footprint in a CBDC-enabled world, especially if Privacy-Enhancing Technologies (PETs) become widely adopted.
  The changes in data access also have implications for credit scoring and financial inclusion. While reduced access to traditional bank transaction data could pose challenges for existing credit scoring models, CBDC transaction histories—even if anonymized or pseudonymized for general public view—could potentially be accessed with user consent or through specific regulatory gateways to build alternative credit profiles. This could be particularly beneficial for individuals currently unbanked or underbanked, who lack traditional credit histories. While posing a challenge to established models, this also presents an opportunity for banks to develop new, more inclusive credit assessment methodologies, potentially expanding their customer base to previously underserved segments, provided they can navigate the evolving data access and privacy regulations effectively.

3. Igniting New Waves of Competition and Innovation

The arrival of CBDCs is poised to significantly stir the competitive cauldron of the financial services industry, potentially unlocking new avenues for innovation.

• CBDCs as a Competitive Catalyst
  The introduction of a sovereign digital currency, designed to be a low-cost, efficient, and secure public payment option, will inevitably exert considerable competitive pressure on existing payment service providers, including commercial banks. This new public infrastructure could drive down the fees associated with traditional payment services, such as card transactions and bank transfers, and compel incumbent players to enhance their own offerings to remain competitive. Banks may find their traditional revenue streams from payment processing challenged, forcing them to seek greater efficiencies or new value propositions.
• New Roles for Banks in a CBDC Ecosystem: The Public-Private Partnership Model
  Despite the competitive pressures, most CBDC designs, particularly for retail applications, are not intended to sideline commercial banks entirely. Instead, they often envision a “two-tier” or “intermediated” operational model. In such a system, the central bank would be responsible for issuing the CBDC and maintaining the core payment ledger’s integrity. However, private sector entities—prominently including commercial banks and other regulated payment service providers (PSPs)—would manage all customer-facing services.21
  This collaborative framework opens up several potential new roles and opportunities for banks :
  • Wallet Provision: Banks could offer digital wallets that allow customers to securely hold, manage, and transact with CBDCs, potentially integrating these wallets into their existing mobile banking applications.
  • Onboarding and KYC/AML Compliance: Banks would likely continue to perform essential customer due diligence, including Know Your Customer (KYC) and Anti-Money Laundering (AML) checks, for CBDC users, leveraging their existing expertise and infrastructure.
  • Value-Added Services: This is a significant area for innovation. Banks could build a host of new services on top of the basic CBDC platform. Examples include enabling programmable payments for automated bill settlements or complex business transactions, integrating CBDC functionalities with other financial products like loans or investments, and offering sophisticated financial management tools that incorporate CBDC holdings.
  • Interoperability Services: Banks could play a role in facilitating the seamless exchange between CBDCs, traditional commercial bank money, and potentially other digital assets, ensuring that the financial system remains interconnected.

The Bank of England’s proposed model for a “digital pound” explicitly details such a public-private partnership, outlining roles for Payment Interface Providers (PIPs) and External Service Interface Providers (ESIPs). These roles could be filled by existing banks, new FinTech companies, or a combination thereof, creating a diverse ecosystem.

• A Springboard for Fintech and New Entrants
  Standardized CBDC platforms, particularly if they are designed with open Application Programming Interfaces (APIs), could significantly lower the barriers to entry for FinTech companies and other new players in the financial services market. This could foster a more dynamic and innovative environment, leading to a wider array of payment solutions and financial products for consumers and businesses. The accessibility of a core, public payment infrastructure could allow FinTechs to focus on developing niche or specialized services without the need to build foundational payment rails from scratch.
  The evolving landscape suggests a future where “coopetition” becomes the new norm for banks. They will find themselves competing not only with new FinTech entrants but also, in a sense, with the central bank itself (which would be providing a basic, utility-like payment instrument). Simultaneously, banks will need to cooperate extensively: with the central bank, by acting as distributors and service providers within the two-tier CBDC model, and potentially with FinTechs, through strategic partnerships, by consuming their specialized services, or by offering their own banking-as-a-service platforms. This complex interplay of competition and cooperation will demand new strategic thinking from banks. Their success will hinge on their ability to clearly identify and leverage their unique strengths—such as established customer trust, extensive client bases, and deep regulatory expertise—while simultaneously embracing collaboration and open innovation to navigate this reshaped ecosystem.
  This could lead to an “App Store” model for financial services. If CBDC platforms are indeed built with robust and open APIs, they could function much like a mobile operating system. In this scenario, commercial banks and FinTech companies could develop and offer specialized “apps”—value-added services and products—that plug into this core CBDC infrastructure. Such a development could accelerate the “unbundling” of traditional banking services, where customers are able to pick and choose individual services from a variety of providers, all interacting seamlessly with a common CBDC payment rail. In this environment, banks might transition from being the sole gatekeepers of financial services to becoming one of many service providers in a broader, more open financial ecosystem. Their brand reputation, the quality of their customer experience, and their ability to innovate rapidly would become even more critical differentiators.
  Underpinning these potential shifts is the significant challenge and opportunity related to banks’ core technology infrastructure. Integrating seamlessly with new CBDC systems, supporting novel transaction types like programmable money, and enabling rapid innovation through APIs will place immense new demands on the often-aging legacy IT systems prevalent in many banks. Many existing core banking systems were not designed for the level of flexibility, real-time processing, or open connectivity that a CBDC-centric future might require. Consequently, the advent of CBDCs could act as a powerful catalyst, accelerating the urgency for banks to undertake comprehensive modernizations of their core technology stacks. This could involve substantial IT investment cycles, a more aggressive adoption of cloud-native architectures, and a fundamental shift towards API-first design principles. For many institutions, this will be a substantial operational and financial undertaking, but one that is crucial for remaining competitive and relevant.

4. Revolutionizing Payment Systems: Domestic and Cross-Border

CBDCs hold the promise of substantially upgrading payment infrastructures, both within national borders and across them, by leveraging their unique characteristics as direct central bank liabilities in digital form.

• Domestic Payments: Faster, Cheaper, More Resilient?
  For domestic transactions, CBDCs aim to enhance the efficiency, speed, and cost-effectiveness of payment systems. Proponents envision CBDCs enabling real-time or near-real-time settlement of payments, available 24 hours a day, 7 days a week. This could lead to potentially lower transaction fees for consumers and merchants compared to existing systems like card networks or traditional bank transfers, which often involve multiple intermediaries and associated costs. For merchants, CBDCs could reduce the complexities and delays associated with payment reconciliation, particularly for transactions that are currently slow to clear.2
  It’s widely anticipated that CBDCs will not replace but rather coexist with and complement existing payment infrastructures, such as Fast Payment Systems (FPS) and e-money networks. A CBDC offers the unique benefit of being a direct claim on the central bank, which can enhance trust and finality in payments. Ensuring interoperability between new CBDC systems and existing payment rails (like Automated Clearing Houses (ACH), card switches, and FPS) is a critical design consideration to prevent fragmentation of the payments landscape and ensure a smooth user experience. Application Programming Interfaces (APIs) are seen as crucial enablers for achieving this interoperability, allowing different systems to communicate and exchange information seamlessly.
• Cross-Border Payments: A Potential Game-Changer
  The arena of cross-border payments is where CBDCs could offer some of their most transformative benefits. Currently, international payments are often characterized by slow processing times, high costs, and a lack of transparency, primarily due to the complex web of correspondent banking relationships that underpin them. Each intermediary in the chain adds fees and delays.
  CBDCs, particularly through innovative multi-CBDC (mCBDC) arrangements or through significantly improved interoperability between individual domestic CBDC systems, have the potential to dramatically reduce these frictions. International projects are actively exploring these possibilities. For example, Project mBridge, a collaboration involving central banks from China, Thailand, the UAE, Hong Kong, and Saudi Arabia, is testing a common platform based on distributed ledger technology (DLT) for real-time, peer-to-peer cross-border payments with the goal of instant settlement. Similarly, Project Agorá brings together seven major central banks (including the US Federal Reserve) and private sector firms to explore the use of tokenized commercial bank money and wholesale CBDCs on a unified ledger to streamline international transactions. Even SWIFT, the incumbent global financial messaging network, is actively experimenting with solutions to ensure that CBDCs can interoperate effectively with each other and with traditional payment systems, aiming to bridge the old and new financial infrastructures.
• Programmability and Smart Contracts: The Next Frontier
  A particularly exciting dimension of CBDCs, especially if they are token-based or built on DLT platforms, is their potential to support programmability. This refers to the ability to embed predefined rules, conditions, or logic directly into the money itself or, more commonly, into the transactions involving CBDCs. The IMF clarifies that to maintain the essential characteristic of fungibility (where one unit of money is perfectly interchangeable with another), programmability would likely apply to CBDC transactions rather than the CBDC units themselves.13
  This capability could unlock a wide range of innovative use cases. For instance, programmable payments could automate complex payment schedules, facilitate instant and automated Delivery-versus-Payment (DvP) in securities settlements (where an asset is transferred if and only if payment is made), enable machine-to-machine (M2M) payments in the Internet of Things (IoT) ecosystem, and streamline complex supply chain finance arrangements.
  The potential for more efficient and automated payment systems, especially across borders, could lead to a redefinition of correspondent banking. If multi-CBDC platforms like Project mBridge become widespread and demonstrate superior efficiency for cross-border payments, the traditional role of correspondent banks in facilitating these transactions—acting as intermediaries, holding nostro/vostro accounts, and managing settlement risk—could be significantly diminished. By reducing the layers of intermediaries, these new platforms aim to lower fees and dramatically shorten settlement times. Banks that currently derive substantial revenue from correspondent banking services will face a major disruption. They will need to adapt by finding new roles, perhaps in providing specialized foreign exchange (FX) services for these new platforms, offering compliance and regulatory advisory related to cross-jurisdictional CBDC flows, or providing secure access points and value-added services on top of these emerging multi-CBDC networks. The entire business model underpinning cross-border settlement could be fundamentally upended.
  Beyond just speed and cost, programmable money has the potential to unlock entirely new financial products and enhance risk management tools for banks. The ability to automate complex financial agreements—such as ensuring automated coupon payments on bonds, or creating self-executing escrow services directly embedded within transactions—opens up new possibilities. Banks could leverage this programmability to design and offer novel, more efficient, and highly tailored financial products to both their corporate and retail clients. This isn’t merely about making existing payments faster; it’s about enabling smarter payments and more sophisticated financial contracts. This could lead to new lines of business for banks in designing, managing, and executing these programmable financial instruments, potentially reducing operational risks and costs for themselves and their clients, and creating new forms of value.
  However, realizing the full potential of CBDCs in cross-border payments necessitates a heightened focus on international standardization and governance. For multi-CBDC arrangements or interconnected domestic CBDC systems to function effectively and achieve widespread adoption, significant international cooperation on technical standards (e.g., for messaging, APIs, DLT protocols), legal frameworks (e.g., for settlement finality, conflict of laws), and governance models (e.g., for oversight, dispute resolution) will be indispensable. A lack of such standardization could lead to a fragmented global landscape of incompatible CBDC systems, which would negate many of the anticipated benefits and could even introduce new complexities. Banks operating internationally will need to navigate this complex and continuously evolving web of regulations and standards. Their ability to adapt to different CBDC protocols, ensure compliance across diverse jurisdictions, and manage the operational intricacies of interacting with multiple CBDC systems will become a key competitive factor. This evolving landscape also creates opportunities for specialized firms focusing on developing and providing cross-CBDC interoperability solutions and advisory services.

5. Recalibrating Financial Stability Risks

While CBDCs offer numerous potential benefits, their introduction also necessitates a careful recalibration of financial stability risks, extending beyond simple disintermediation.

• Bank Runs in the Digital Age
  A primary financial stability concern repeatedly highlighted in analyses is that the inherent safety and ease of converting commercial bank deposits into CBDCs (which are direct, risk-free liabilities of the central bank) could significantly accelerate bank runs, especially during periods of financial stress or uncertainty. If depositors perceive their commercial bank to be in trouble, the ability to instantaneously move funds into a CBDC wallet could make deposit flights faster and larger than what is possible with physical cash withdrawals or traditional bank transfers.7
  Central banks are acutely aware of this “digital run” risk. Design features such as holding limits on CBDC balances and tiered or zero remuneration are specifically intended to mitigate this threat by making CBDCs less attractive as a large-scale, rapidly accessible store of value during a panic. The ECB’s research even suggests a complex, U-shaped relationship between the level of CBDC remuneration and bank fragility: while very low or very high remuneration could increase fragility, a moderate level might paradoxically enhance stability by compelling banks to offer more attractive terms on their own deposits, thereby strengthening their funding base.
• Impact on Non-Bank Financial Intermediaries (NBFIs)
  The financial stability implications of CBDCs are not confined to the traditional banking sector. Non-Bank Financial Intermediaries, such as Money Market Funds (MMFs), could also be affected. In a crisis scenario, investors might rapidly withdraw funds from MMFs and other short-term investment vehicles to seek the safety of CBDCs, mirroring the potential for runs on bank deposits. This could disrupt funding for NBFIs and have knock-on effects in the markets where they invest.
  Conversely, CBDCs could also offer new, highly secure settlement assets for transactions involving NBFIs, or they could foster increased competition in the types of payment and financial services that NBFIs currently offer. The Financial Stability Board (FSB) is actively monitoring these evolving dynamics and the potential for CBDCs to reshape the NBFI landscape.
• Cybersecurity – A Systemic Concern
  The entire CBDC ecosystem—encompassing central banks, participating commercial banks, payment service providers, technology vendors, and end-users—will present a complex and highly attractive target for cyberattacks. A successful large-scale cyberattack on a CBDC system could have devastating consequences, potentially undermining public confidence not only in the CBDC itself but also in the broader financial system and the central bank. Ensuring robust, multi-layered cybersecurity, resilience against operational failures, and effective incident response capabilities will be paramount and a continuous challenge.
• Central Bank’s Expanded Role and Footprint
  The introduction of a retail CBDC, even if operated through a two-tier model where private intermediaries manage customer-facing services, inherently expands the central bank’s direct interaction with the retail payment system and potentially enlarges its balance sheet. The manner in which the central bank chooses to manage its new CBDC liabilities—for instance, by recycling the absorbed funds back to commercial banks through lending facilities or by purchasing assets from the market—will have significant implications for overall financial stability and the functioning of money markets.25
  The potential for CBDCs to amplify procyclicality during financial stress warrants particular attention. Fixed holding limits or static remuneration policies for CBDCs might prove effective in maintaining stability during normal economic times. However, during a severe crisis, these pre-set limits could be insufficient to prevent large-scale flights to safety, or they might even become counterproductive if they unduly restrict legitimate access to liquidity. The sheer ease and speed of CBDC withdrawals could exacerbate procyclical capital movements. This implies that central banks and regulatory authorities might need to consider developing dynamic safeguards for CBDCs. For example, they might need the ability to adjust CBDC holding limits, convertibility rules between CBDC and commercial bank money, or even transaction fees during periods of acute systemic stress. While potentially useful for crisis management, such dynamic interventions would introduce a new layer of complexity and could create uncertainty for commercial banks regarding the “rules of the game” under duress, impacting their liquidity planning and risk management.
  Furthermore, the operational model of CBDCs, especially the prevalent two-tier system, could lead to a shift in systemic importance and the focus of regulatory oversight. In this model, private sector intermediaries—such as Payment Interface Providers (PIPs) or wallet providers—become critical infrastructure for the public’s access to and use of central bank money. Consequently, operational failures, cybersecurity breaches, or the insolvency of these private intermediaries could have systemic consequences, even if the underlying CBDC core ledger maintained by the central bank remains secure and resilient. This suggests that the regulatory perimeter will likely need to expand to cover these new types of systemically important players with greater intensity. Commercial banks choosing to act as PIPs or major CBDC service providers will likely face heightened operational resilience standards and closer supervisory scrutiny. This also implies that “too big to fail” considerations might extend beyond traditional banks to a new class of FinTech companies that become integral to the functioning of the CBDC ecosystem.
  Interestingly, with appropriate safeguards and regulatory access, CBDC systems could offer a novel “early warning system” for bank distress, albeit with significant caveats. If regulators have the ability to observe large, sudden, and anomalous inflows into CBDCs from specific institutions (even if individual user data remains private), this could provide early signals of perceived weakness or liquidity stress at those institutions. This assumes a level of transparency for regulatory authorities that must be carefully balanced against overarching privacy principles. While potentially providing regulators with a new tool for monitoring financial stability in near real-time, this capability also introduces the risk of self-fulfilling prophecies or pre-emptive runs if the market anticipates such signals or if there are information leaks regarding these flows. Commercial banks might, therefore, face new forms of market scrutiny and reputational risk based on perceived or actual movements of funds between their deposit accounts and CBDCs.

6. Influencing Monetary Policy Implementation

The introduction of CBDCs, particularly retail variants, could have multifaceted effects on the tools, transmission, and overall conduct of monetary policy.

• Impact on Bank Reserves and Interest Rates
  Widespread adoption of CBDCs has the potential to alter the public’s demand for commercial bank deposits and, consequently, the aggregate level of reserves that commercial banks hold at the central bank. If individuals and businesses choose to hold a significant portion of their liquid assets in CBDC instead of bank deposits, banks would see a corresponding reduction in their deposit liabilities and, potentially, their reserve balances held with the central bank. This shift can influence short-term money market interest rates and may complicate the central bank’s tasks of forecasting liquidity needs in the banking system and managing overall liquidity conditions. The specific impact would depend on whether CBDC primarily substitutes for physical cash or for bank deposits; substitution for cash might have a more neutral effect on bank reserves than substitution for deposits.
• Transmission of Monetary Policy
  CBDCs, especially if they are designed to be interest-bearing, could potentially strengthen or otherwise alter the transmission mechanisms of monetary policy. An interest-bearing CBDC could, in theory, provide a more direct channel for the central bank’s policy interest rate changes to pass through to rates faced by consumers and businesses. This is because the rate on CBDC could act as a benchmark or floor for deposit rates offered by commercial banks. However, the effectiveness of this channel is nuanced. A Bank for International Settlements (BIS) working paper suggests that while a CBDC interest rate can initially improve pass-through, increasing it beyond a certain point (where it becomes a binding floor for bank deposit rates) might actually reduce the responsiveness of overall deposit rates to subsequent policy rate changes, particularly if it leads to greater market concentration.61
  Conversely, a non-remunerated CBDC, by providing a readily available zero-interest alternative to bank deposits, could “harden” the effective lower bound (ELB) for nominal interest rates. If interest rates on bank deposits were to go significantly negative, people might prefer holding zero-interest CBDC, limiting how far negative rates could be transmitted.
• New Monetary Policy Tools?
  Some academic literature has explored the possibility that CBDCs could offer central banks new, more direct monetary policy tools. For example, in certain CBDC designs (particularly those involving direct accounts with the central bank, which are not the preferred model for most retail CBDC proposals currently), it might be technically feasible to conduct “helicopter money” drops by directly crediting citizens’ CBDC accounts. Similarly, CBDCs could theoretically facilitate the implementation of negative interest rates more effectively if the use of physical cash (which offers a zero nominal interest rate) declines significantly. However, these potential tools are often controversial, raise significant policy and operational questions, and their viability depends heavily on specific CBDC design choices that many central banks are currently shying away from for retail versions. The predominant focus in most jurisdictions is on ensuring that CBDCs, first and foremost, do no harm to the existing effectiveness and implementation of monetary policy.
• Central Bank Operational Adjustments
  Regardless of the specific design, central banks will likely need to adapt their existing monetary policy operations to accommodate the effects of CBDCs. This could involve engaging in more frequent or larger-scale fine-tuning operations (e.g., short-term lending or borrowing facilities) to manage liquidity fluctuations in the banking system, or adjusting the overall supply of reserves to ensure that policy objectives are met.3
  A key consideration arising from these potential impacts is the likelihood of increased volatility in the banking system’s demand for central bank reserves. The ease with which funds might flow between commercial bank deposits and CBDCs, especially if digital interfaces are seamless and user-friendly, could make commercial banks’ day-to-day demand for reserves at the central bank more unpredictable and prone to larger swings. This heightened volatility would make it more challenging for the central bank to forecast liquidity needs accurately. As a result, central banks might find themselves needing to conduct open market operations more frequently or with greater precision. They might also need to offer more flexible standing facilities (through which banks can borrow or deposit reserves) to help commercial banks manage these short-term liquidity fluctuations. This could subtly change the day-to-day operational dynamics and relationship between commercial banks and their central bank.
  Furthermore, the very design choices of a CBDC can function as de facto monetary policy instruments. Decisions regarding whether a CBDC is remunerated and at what rate, the imposition of holding limits, and even features affecting its convenience and ease of use (as highlighted in BIS research ) will directly influence its attractiveness relative to commercial bank deposits and physical cash. These design parameters, therefore, are not merely technical details; they have direct and significant implications for market-determined deposit rates, the competitive market shares of banks, and the overall pass-through of official monetary policy rates to the broader economy. This implies that the technical architecture of a CBDC becomes an implicit, if not explicit, lever of monetary influence. Commercial banks will, therefore, need to closely monitor not just official interest rate announcements from the central bank but also any discussions, consultations, or decisions related to CBDC design parameters, as these could significantly impact their competitive positioning and funding costs.
  While there are complexities, there is also the potential for enhanced monetary policy transmission in specific scenarios, albeit with trade-offs. For instance, in situations where commercial banks are slow or reluctant to pass on changes in the central bank’s policy rate to their depositors (perhaps due to market power or other frictions, as suggested in some research ), an appropriately remunerated CBDC could act as a competitive floor, encouraging better pass-through. However, as the same research cautions, if the CBDC interest rate becomes too dominant or is set too high, it could also reduce banks’ overall responsiveness to policy changes in the longer run and potentially lead to greater market concentration by favoring larger institutions or those better able to adapt. This presents a delicate balancing act for central banks. While CBDCs could theoretically be used as a tool to address certain imperfections in the monetary policy transmission mechanism, deploying them aggressively for this purpose could exacerbate risks of bank disintermediation and fundamentally alter the structure of the banking market. Commercial banks, therefore, face a future where the central bank might possess a more direct instrument to influence their deposit pricing behavior, adding another layer to their strategic considerations.

7. Intensifying the Spotlight on Financial Data and Privacy

The digital nature of CBDCs inherently brings issues of data generation, access, and privacy to the forefront, creating a complex balancing act for policymakers and financial institutions.

• The “Digital Trail” and Privacy Concerns
  Unlike physical cash, which allows for anonymous transactions, CBDCs, being digital, will inherently create a “digital trail” or record of transactions. This has sparked significant public concern regarding the potential for increased government surveillance, loss of financial privacy, and the ability of authorities to track citizens’ spending habits. These concerns are often voiced in comparison to the anonymity afforded by cash.7
  Central banks and governments are highly sensitive to these concerns and have generally committed to upholding high privacy standards in CBDC design. For example, the Bank of England has stated that neither it nor the government would access users’ personal data from a digital pound system, and the ECB has emphasized that the Eurosystem would not be able to identify users or their purchases from the payment data it might receive in a digital euro context.
• Balancing Privacy with AML/CFT Compliance
  A critical challenge for CBDC design is to strike an appropriate balance between protecting user privacy and enabling authorities to effectively combat money laundering (AML), the financing of terrorism (CFT), and other illicit financial activities. Fully anonymous CBDCs are generally not favored by policymakers due to these legitimate law enforcement and financial integrity concerns.21
  It is widely expected that Know Your Customer (KYC) requirements will apply to CBDC users, similar to traditional bank accounts. In the prevalent two-tier CBDC models, these KYC obligations would likely be carried out by the private sector intermediaries (banks and PSPs) that provide users with CBDC wallets and services.
• Technological Solutions: Privacy-Enhancing Technologies (PETs)
  To address the dual needs of privacy and compliance, central banks and researchers are actively exploring the integration of Privacy-Enhancing Technologies (PETs) into CBDC architectures. PETs aim to minimize data exposure and allow for secure data processing while preserving confidentiality. Key examples being investigated include:
  • Zero-Knowledge Proofs (ZKPs): These cryptographic methods allow one party to prove to another that a statement is true (e.g., that a user has sufficient funds for a transaction, or that a transaction complies with certain regulatory thresholds) without revealing any underlying data beyond the truth of the statement itself.
  • Homomorphic Encryption (HE) and Secure Multi-Party Computation (SMPC): HE allows computations to be performed directly on encrypted data without needing to decrypt it first. SMPC enables multiple parties to jointly compute a function over their private inputs without revealing those inputs to each other. These could be used for privacy-preserving data analytics or compliance checks.
  • Pseudonymization and Other Anonymization Techniques: These methods aim to obscure or remove direct identifiers from transaction data, reducing the risk of linking transactions back to specific individuals, while still allowing for aggregated data analysis or targeted de-anonymization under strict legal conditions.

The IMF has proposed a comprehensive framework to help countries manage the trade-offs between CBDC data utilization and privacy protection. This framework emphasizes the importance of robust institutional arrangements (like clear legal mandates and oversight), sound data governance policies (covering collection, access, and storage), judicious design choices (adopting “privacy-by-design” principles), and the strategic deployment of technological solutions, including PETs.

• Account-based vs. Token-based CBDCs and Privacy Implications
  The underlying architecture of a CBDC—whether it is account-based or token-based—has significant implications for privacy:
  • Account-based CBDCs typically link transactions directly to a verified digital identity of the account holder. While this model can simplify AML/CFT compliance (often seen as a central bank or direct intermediary responsibility ), it may inherently offer less transactional privacy unless augmented with strong PETs.
  • Token-based CBDCs, on the other hand, can be designed to offer more cash-like anonymity for transactions. In a token-based system, access and ownership are often verified through cryptographic keys (e.g., public-private key pairs) rather than direct linkage to a formal identity for every transaction. However, this approach poses greater challenges for AML/CFT enforcement. Even in token-based systems, intermediaries providing wallets would likely still be responsible for initial KYC at onboarding, and there’s a higher risk for users if they lose their private keys or tokens.

The intense focus on data and privacy in the CBDC context could position banks as crucial “privacy custodians” in a two-tier system. Given that in most proposed retail CBDC models, commercial banks and other PSPs will serve as the primary interface for end-users—handling KYC procedures and potentially managing some level of transaction data (even if it’s pseudonymized from the central bank’s perspective)—a significant responsibility will fall on these institutions. They will not only need to rigorously comply with AML/CFT regulations but also be perceived by their customers as trustworthy guardians of their CBDC-related data. This implies that a bank’s brand reputation for security, data protection, and ethical data handling will become an even more critical asset. Banks may need to make substantial investments in implementing PETs within their own systems and in developing transparent data governance frameworks to maintain and build customer trust. This commitment to privacy could evolve into a key competitive differentiator in the market for CBDC services.Furthermore, the “privacy versus utility” trade-off will become a core challenge in banking product design. Different users will inevitably have varying preferences regarding financial privacy. Some may prioritize maximum anonymity, even if it means forgoing certain conveniences or features. Others might be willing to share more data in exchange for more personalized services, higher transaction limits, or easier access to credit. Banks, acting as wallet providers and service intermediaries, will likely need to offer users choices or tiered levels of privacy, potentially linked to different product features, transaction capabilities, or identity verification levels (an idea explored by Bank of England working groups ). Designing CBDC wallets and associated financial services will thus require banks to navigate this complex trade-off meticulously. It will no longer be solely about efficient transaction processing but also about effectively managing diverse user data preferences within a highly regulated yet acutely privacy-sensitive environment. This could lead to more sophisticated and customizable product offerings but will also necessitate clear and comprehensive customer education on data use and privacy options.Finally, the unique characteristics of CBDC data—being a direct liability of the central bank but often handled and intermediated by private sector entities—may necessitate the development of new or significantly adapted regulatory frameworks for “CBDC data handlers.” Existing data protection regulations, such as GDPR, will undoubtedly apply, but the specific nature of CBDC systems might require more tailored rules. These could govern precisely what data PIPs and other intermediaries can access, how long they can store it, for what purposes they can use it, and how the implementation and auditing of PETs are to be overseen. Banks and other financial institutions will need to be prepared for an evolving regulatory landscape specifically addressing CBDC data. While this could entail increased compliance costs and operational adjustments, clear and robust legal frameworks could also provide the necessary certainty for fostering innovation and building public trust in the CBDC ecosystem. This also means that banks’ compliance departments and legal teams will need to develop new expertise in this specialized area of data protection and digital currency regulation.

The Global CBDC Race: What Investors and Banks Should Watch

The exploration and development of CBDCs is a global phenomenon, with countries progressing at different speeds and with varying motivations. Understanding this international landscape is crucial for banks and investors looking to anticipate future trends.

• A World of Exploration
  As previously noted, over 130 countries are actively involved in some form of CBDC work. Several key projects and national stances illustrate the diversity of approaches:
  • China’s e-CNY: This remains the largest and most advanced retail CBDC pilot globally. The e-CNY has seen significant transaction volumes and is being integrated into everyday retail payments, including via QR code systems. Motivations appear to include enhancing domestic payment efficiency, increasing financial surveillance capabilities, and potentially promoting the international use of the renminbi.
  • Eurozone’s Digital Euro: The ECB is in a “preparation phase” for a potential digital euro, focusing on developing a rulebook and selecting technology providers. Key objectives include providing European citizens with a sovereign digital payment option, preserving the monetary sovereignty of the Eurozone in an increasingly digital world, and fostering innovation in payments. Strong emphasis is being placed on privacy within a two-tier intermediated model, with considerations for holding limits and offline payment capabilities.
  • UK’s Digital Pound: The Bank of England and HM Treasury are in a “design phase” for a potential “digital pound”. They are exploring a public-private platform model where private firms (PIPs and ESIPs) would provide user-facing services. Primary motivations include ensuring continued public access to central bank money as cash use declines and promoting innovation and efficiency in domestic payments. Offline payments are acknowledged as a technically challenging aspect.
  • United States’ Stance: The US has adopted a more cautious approach regarding a retail CBDC. There is no definitive decision to issue one, and some influential policymakers have expressed a preference for privately issued, well-regulated stablecoins to maintain the dollar’s international role. However, the US is actively participating in research and experimentation, particularly in the wholesale CBDC space, through initiatives like Project Agorá, which involves collaboration with several other major central banks.
  • Launched CBDCs (e.g., Bahamas, Jamaica, Nigeria, Eastern Caribbean): Countries that have already launched retail CBDCs offer valuable early lessons. Generally, adoption rates have been slow. Challenges identified include insufficient public awareness and education, a lack of widespread merchant participation, and inadequate incentives for intermediaries to promote and distribute the CBDC. These early experiences highlight that technical issuance is only one part of a successful CBDC rollout.
• Key Trends for Banks to Monitor
  For commercial banks and investors, several key trends in CBDC development warrant close monitoring:
  • Dominant Design Choices: Which features become common across major CBDC projects? This includes decisions on remuneration (interest-bearing or not), the nature and level of holding limits, access models (account-based versus token-based), and the robustness of privacy-enhancing features. These choices will heavily influence how CBDCs interact with existing banking products and services.
  • Evolution of Public-Private Partnership Models: The specific roles, responsibilities, and compensation models defined for commercial banks and other private sector entities in two-tier CBDC systems will be critical. This will determine the opportunities and challenges for banks in a CBDC ecosystem.
  • Progress in Interoperability Efforts: The success of international projects like mBridge and Agorá, as well as initiatives by organizations like SWIFT to ensure interoperability between different CBDC systems and with traditional financial infrastructure, will determine the extent to which CBDCs can streamline cross-border payments.
  • Regulatory Developments: The evolving landscape of regulations governing CBDCs—covering areas such as data protection and privacy, AML/CFT compliance, consumer protection, and the prudential treatment of CBDC-related activities for banks—will shape the operational environment.
  • Adoption Rates and User Behavior: Real-world data from ongoing pilots and fully launched CBDCs on user adoption patterns, preferred use cases, and the extent to which CBDCs displace or complement existing payment methods will provide crucial insights into their ultimate market impact.

The global pursuit of CBDCs carries significant geopolitical implications, particularly for international banks. The emergence of distinct CBDC systems or blocs—potentially centered around major currencies like the yuan, the euro, or a future digital dollar (or dollar-backed stablecoins)—could create new geopolitical fault lines in the international financial system. Cross-border CBDC arrangements might be designed in ways that favor certain currency corridors or, conversely, are used to bypass or exclude others, potentially influenced by international sanctions regimes or shifting geopolitical alliances. International banks will need to navigate these complex and evolving dynamics. Their ability to operate seamlessly across different CBDC platforms, comply with varying regulatory requirements in multiple jurisdictions, and manage the associated operational risks could become a critical strategic challenge and a source of competitive advantage or disadvantage. This complex environment might also influence their decisions on where to allocate resources, focus their international operations, and invest in technology.This leads to a “standard-setting” race with potential first-mover (dis)advantages. Countries or economic blocs that successfully design, implement, and scale their CBDCs first—as China is attempting with the e-CNY—might establish de facto standards for technology, interoperability protocols, and even regulatory approaches. This could give them a significant advantage in shaping the future architecture of the global digital payment landscape. However, being a first mover is not without its risks. Early adopters inevitably face unforeseen technological challenges, bear the costs of initial infrastructure development, and learn from early mistakes in areas like user adoption strategies or security protocols. Later adopters can benefit from these lessons. For banks, this creates a strategic dilemma: they need to closely monitor which CBDC models gain traction and which technical and regulatory standards emerge. Early investment in capabilities aligned with successful models could be highly beneficial, but betting on a model that fails to gain widespread acceptance could be a costly misstep. This necessitates a cautious yet proactive approach to investing in CBDC-related technologies and expertise.Finally, the observed adoption challenges in countries with launched CBDCs suggest that the impact on banking may be more evolutionary than revolutionary, at least in the initial phases. The slow uptake of CBDCs in places like Nigeria and the Bahamas indicates that overcoming user and merchant inertia, building public trust, and demonstrating a clear and compelling value proposition that goes beyond existing digital payment options is a substantial undertaking. The classic “chicken-and-egg” problem—where consumers hesitate to adopt a new payment method until merchants widely accept it, and merchants are reluctant to invest in acceptance infrastructure until there is significant consumer demand—remains a significant hurdle. While the potential for CBDCs to fundamentally revolutionize the banking sector is vast, the actual pace of transformation may be more gradual and incremental, particularly in the short to medium term. This potentially gives incumbent banks more time to adapt, innovate, and develop their strategies. However, they cannot afford complacency, as the underlying technological shifts and competitive pressures driving the CBDC agenda are real and persistent.

Navigating the CBDC Revolution in Banking

Central Bank Digital Currencies represent a watershed moment for the global financial system, with the potential to profoundly reshape the banking landscape as we know it. The seven key transformations explored—from the fundamental structure of bank deposits and funding to the intricacies of payment systems, financial stability, monetary policy, and data privacy—underscore the depth and breadth of CBDCs’ potential influence.

Banks find themselves at a critical crossroads. On one hand, CBDCs present formidable challenges: the risk of disintermediation as depositors gain a direct, risk-free digital alternative; pressure on net interest margins due to increased funding competition; the emergence of new competitors, including FinTechs leveraging CBDC infrastructure; and the need to navigate complex operational and regulatory changes. On the other hand, CBDCs also unlock significant opportunities: the potential to offer new value-added services built upon CBDC platforms; efficiency gains in domestic and cross-border payments; a catalyst for modernizing legacy systems; and a chance to enhance financial inclusion.

The path forward for the banking sector will not be uniform. The strategic challenge for each institution will be to determine its place on a spectrum ranging from providing essential “utility” access to CBDCs to offering highly differentiated, value-added services. Some banks might focus on becoming efficient processors and distributors within the two-tier CBDC model, competing on operational excellence and cost. Others will need to innovate aggressively, moving up the value chain to provide sophisticated advisory services, wealth management solutions tailored to a digital asset environment, specialized lending products, or innovative applications of programmable money. This is a fundamental question of identity and strategic direction for many banking institutions.

Proactive adaptation, therefore, is not just advisable; it is imperative. Banks that deeply understand the multifaceted shifts heralded by CBDCs and proactively adjust their business models, invest in enabling technologies, and rethink their customer engagement strategies will be the ones best positioned to navigate this new era successfully. This involves more than just reacting to regulatory mandates; it requires a forward-looking approach that embraces innovation, explores potential collaborations with FinTechs and even central banks, and maintains an unwavering focus on delivering tangible value to customers in an increasingly digital monetary ecosystem.

For investors, this period of transition will undoubtedly create both winners and losers within the banking and broader financial technology sectors. Companies that demonstrate agility, foresight, and the ability to capitalize on the new possibilities offered by CBDCs may see significant growth. Conversely, those that are slow to adapt or are overly reliant on business models vulnerable to CBDC-induced disruption could face considerable headwinds. Astute investors will therefore closely monitor the pace of CBDC developments globally, the strategic responses of incumbent financial institutions, the emergence of new, innovative business models, and the evolving regulatory frameworks that will govern this new form of money.

Ultimately, the rise of CBDCs is part of a larger narrative about the future of money itself, prompting a re-evaluation of the roles of public and private sectors in its provision and governance. The long-term trajectory could see a closer integration and interoperability between public digital money (CBDCs) and private digital money (such as well-regulated stablecoins and tokenized commercial bank deposits), creating a richer, more diverse financial ecosystem. Alternatively, it could lead to ongoing competition and divergence based on different use cases, regulatory philosophies, and user preferences. Commercial banks will find themselves at the heart of this dynamic, needing to facilitate and adapt to both forms of digital currency. The journey ahead is complex, but for those prepared to innovate and evolve, the era of Central Bank Digital Currencies holds the promise of a more efficient, inclusive, and dynamic financial future.

The following table summarizes some of the potential impacts on key banking functions discussed:

Frequently Asked Questions (FAQ) about CBDCs and Banking

• Q1: Will CBDCs completely replace physical cash?
  • Answer: No. The overwhelming consensus from central banks, including the European Central Bank and the Bank of England, is that CBDCs are intended to complement physical cash, not replace it. Cash provides unique benefits, such as offline usability and a high degree of privacy for users, and central banks aim to ensure its continued availability and acceptance alongside new digital options.
• Q2: Are CBDCs the same as cryptocurrencies (like Bitcoin) or stablecoins?
  • Answer: No, they are fundamentally different. CBDCs are digital currencies issued by a country’s central bank, making them a direct liability of the state. They are backed by the full faith and credit of the government, ensuring their value is stable and equivalent to the nation’s existing fiat currency. Cryptocurrencies like Bitcoin are typically decentralized, created by private entities or networks, are not backed by any central authority, and their value can be highly volatile. Stablecoins are also privately issued but aim to maintain a stable value by being pegged to an underlying asset, often a major fiat currency like the US dollar. However, they still carry issuer-specific risks and risks related to the quality and transparency of their reserves.
• Q3: If CBDCs are introduced, will I still need my commercial bank account?
  • Answer: Yes, it is highly probable that you will. Most retail CBDC models currently under consideration, often referred to as “two-tier” or “intermediated” systems, envision commercial banks and other regulated payment service providers playing a crucial role. These intermediaries would likely provide users with access to CBDCs (e.g., through digital wallets integrated into existing banking apps) and offer related customer services, including onboarding and support. Furthermore, your commercial bank account will continue to be essential for a wide range of other financial services that CBDCs are not designed to offer, such as interest-bearing savings accounts, loans, mortgages, investment products, and potentially for funding your CBDC wallet or converting CBDC holdings back into commercial bank money.
• Q4: How will CBDCs affect my financial privacy?
  • Answer: Financial privacy is a paramount design consideration for CBDCs. While all digital transactions inherently create some form of data trail, central banks globally have expressed strong commitments to ensuring high privacy standards for CBDC users. They generally state that they would not have access to personally identifiable data of CBDC users or monitor individual transactions directly. In most two-tier models, intermediaries like your bank would be responsible for Know Your Customer (KYC) procedures and would have access to some transaction data, primarily to comply with Anti-Money Laundering (AML) and Countering the Financing of Terrorism (CFT) regulations, similar to their obligations today. Some CBDC designs are exploring features that could offer cash-like levels of privacy for certain types of transactions, such as low-value or offline payments. Additionally, Privacy-Enhancing Technologies (PETs) like zero-knowledge proofs and homomorphic encryption are being actively researched to minimize data exposure and enhance confidentiality within CBDC systems.
• Q5: What are the main benefits of CBDCs for me as an average person or investor?
  • Answer: For the average person, potential benefits include access to a highly secure, risk-free form of digital money issued by the central bank. CBDCs could lead to faster, cheaper, and more efficient payments, both domestically and particularly for cross-border transactions, which are often slow and costly. They may also enhance financial inclusion by providing easier and safer access to digital financial services for unbanked or underbanked populations. For investors, the introduction of CBDCs could spur the development of innovative financial products and services within a clearer regulatory environment for digital assets, potentially offering new investment opportunities.
• Q6: What are the biggest risks CBDCs pose to the traditional banking system?
  • Answer: The most significant risk is bank disintermediation. This refers to the potential for a large-scale outflow of deposits from commercial banks as individuals and businesses choose to hold CBDCs instead. Such a shift could strain bank funding sources, reduce their lending capacity, and negatively impact their profitability. Another major concern is the increased potential for digital bank runs during financial crises, as CBDCs could offer an easy and instantaneous way for depositors to flee to safety. Additionally, the entire CBDC ecosystem, including participating banks, will face heightened cybersecurity risks.
• Q7: How could CBDCs impact financial inclusion?
  • Answer: CBDCs are frequently cited as a promising tool to improve financial inclusion. They could provide unbanked or underbanked populations with easier and safer access to basic digital payment services, potentially without requiring a traditional bank account for holding and using a CBDC wallet for essential transactions. CBDCs could offer low-cost or no-fee transactions and help individuals build a verifiable financial transaction history, which could, in turn, improve their access to credit and other financial services. However, realizing these benefits will also depend on addressing challenges such as ensuring widespread digital literacy, providing access to necessary technology (like smartphones or other devices), and ensuring reliable internet or network connectivity, especially in remote areas.
