Intro
Central bank digital currencies (CBDCs) are becoming an increasingly important part of the global financial technology landscape. As digital payments, blockchain infrastructure and tokenised financial assets continue to develop, central banks are exploring how digital versions of national currencies could operate alongside physical cash and commercial bank deposits. Rather than relying entirely on traditional banking infrastructure, these initiatives investigate new platforms capable of supporting secure digital payments, faster settlement and more efficient financial transactions.
During 2026, several major CBDC projects have progressed towards practical testing, with initiatives in Europe, India, Brazil and other financial markets demonstrating different approaches to digital money. Projects such as the digital euro, India’s e-rupee and Brazil’s Drex illustrate how central banks are experimenting with retail payment systems, wholesale settlement and programmable financial infrastructure. Meanwhile, international collaborations such as Project Agorá are exploring how tokenised central bank money could improve cross-border payments. These developments could eventually reshape financial services, although important questions remain around monetary policy, privacy, banking stability and public adoption.
Let’s Dive In
Why Central Bank Digital Currencies Are Becoming More Important
Central bank digital currencies are digital forms of money issued directly by a country’s central bank. Unlike cryptocurrencies such as Bitcoin, CBDCs represent sovereign currency and are backed by the issuing monetary authority.
They are designed to provide a digital alternative to physical cash while maintaining the stability and trust associated with central bank money. Depending on their design, CBDCs can support payments between individuals, transactions between businesses and settlement activities involving commercial banks and financial institutions.
The growing interest in CBDCs reflects several developments within the financial system. Digital payments have become increasingly important, while the use of physical cash has declined in many economies. At the same time, financial institutions are investigating blockchain technology, tokenisation and programmable payments to improve existing services.
The Bank for International Settlements (BIS) reported in its 2025 survey that 91% of 93 central banks surveyed were exploring retail CBDCs, wholesale CBDCs or both. Wholesale projects were generally at more advanced stages of development.
This demonstrates that CBDC development is no longer a relatively isolated research exercise. It has become part of a wider international effort to modernise financial infrastructure and preserve the role of central bank money as financial markets become increasingly digital.
Understanding the Two Main Types of CBDC Platforms
CBDC development generally falls into two categories, each serving different users and financial requirements.
Retail CBDCs
Retail CBDCs are intended for individuals and businesses. They provide a digital form of central bank money that could be used for everyday purchases, online transactions and transfers between individuals.
A retail CBDC could operate through a digital wallet provided by a commercial bank or an authorised payment service provider. Depending on its design, users might be able to make payments online, in physical shops or through offline payment functionality.
The objective is to provide convenient access to central bank money without requiring consumers to handle physical banknotes and coins.
However, retail CBDCs also raise questions about privacy, financial inclusion and competition with commercial bank deposits. Central banks must determine how digital wallets should operate, what information payment providers can access and whether limits should apply to individual holdings.
Wholesale CBDCs
Wholesale CBDCs are designed primarily for financial institutions and other authorised organisations. Their main purpose is to improve the settlement of financial transactions, particularly those involving large payments, securities and international transfers.
These platforms can use distributed ledger technology (DLT) and tokenisation to represent central bank money digitally. This may allow transactions to settle more quickly and reduce the number of intermediaries involved.
Wholesale experiments are particularly relevant to financial markets because settlement delays can increase operational costs and liquidity requirements.
Projects such as Project Agorá demonstrate how wholesale digital money could operate alongside tokenised commercial bank deposits within a shared financial infrastructure.
The New CBDC Platforms and Pilot Programmes to Watch in 2026
The most interesting CBDC developments are emerging from projects with different objectives. Some are developing consumer payment ecosystems, while others are testing wholesale financial infrastructure and programmable settlement.
European Central Bank: The Digital Euro Platform
The European Central Bank (ECB) is developing the digital euro as a potential electronic form of central bank money for everyday payments across the euro area.
Its proposed ecosystem would allow individuals and businesses to use digital euros through payment service providers, including banks and other authorised organisations.
The ECB is investigating online and offline payments, person-to-person transfers and purchases from businesses. The objective is to provide a widely accessible European payment option while maintaining the role of public money within an increasingly digital economy.
An important development occurred in July 2026, when the ECB selected 36 payment service providers to participate in its digital euro pilot. The selection followed more than 50 applications and involved organisations with different business models and geographical coverage.
The pilot is expected to begin during the second half of 2027 and run for 12 months. It will involve selected merchants and Eurosystem staff testing a beta version of the digital euro in everyday payment situations.
The providers will work with the ECB and participating national central banks to develop payment services, integrate with the digital euro service platform and test the underlying infrastructure.
Importantly, this is not a general public launch. The pilot is a controlled exercise intended to assess technical functionality, operational readiness and user experience. The ECB has also made clear that the decision to issue a digital euro will depend on the relevant legislative process.
The project is particularly significant because it demonstrates how central banks can work with established financial institutions and fintech companies to develop a shared digital payment ecosystem.

India: The Digital Rupee and Its Expanding Payment Ecosystem
India’s digital rupee, known as the e₹, is one of the more advanced retail CBDC experiments.
Issued by the Reserve Bank of India (RBI), the digital rupee represents sovereign Indian currency in electronic form. It is designed to provide payment functionality similar to physical cash while supporting digital wallets and modern payment infrastructure.
The retail pilot began in December 2022 and has gradually expanded through participating banks and non-bank payment providers.
One particularly important development is its relationship with India’s Unified Payments Interface (UPI). Interoperability with existing QR-code infrastructure allows users to access digital rupee payments through familiar payment experiences.
This is commercially important because consumers and businesses are more likely to adopt new payment technologies when they can operate alongside services they already understand.
India is also exploring wholesale CBDC applications involving financial institutions and other authorised participants. These initiatives investigate how digital central bank money could improve settlement and the efficiency of financial transactions.
Government figures published in March 2026 reported that the retail pilot had reached approximately 9.2 million participating users and 130 million cumulative transactions by January 2026.
The RBI’s October 2026 guidance confirms that both retail and wholesale e₹ pilots remain part of its development programme.
India’s approach demonstrates how CBDCs can be introduced through existing banking relationships rather than requiring consumers to abandon established payment services.

Brazil: Drex and the Development of Tokenised Financial Services
Brazil’s Drex project is another important experiment in the development of digital financial infrastructure.
Led by the Central Bank of Brazil, Drex was initially introduced as the Digital Real initiative. Its development has increasingly focused on tokenisation, financial asset transactions and the infrastructure needed to support more sophisticated digital financial services.
Rather than concentrating exclusively on everyday consumer payments, Drex is exploring how different financial assets and digital forms of money could operate within an integrated environment.
The pilot uses distributed ledger technology to simulate transactions involving tokenised assets and digital settlement instruments. Potential applications include securities transactions, financial contracts and other activities requiring the exchange of assets and money.
One of the project’s central objectives is to investigate delivery-versus-payment (DvP), where an asset transfer and its corresponding payment take place together.
This could help reduce settlement risk because the two sides of a transaction are designed to complete simultaneously rather than relying on separate processes.
The second phase of the Drex pilot selected 13 themes from 42 proposals. Its experiments have involved financial institutions, regulators and other authorised participants.
An important qualification is that the pilot does not currently represent a general public payment service. The Central Bank of Brazil states that end users are not participants in the pilot and that their transactions are simulated.
Drex is particularly relevant to financial institutions exploring tokenised securities, automated settlement and the future of digital asset markets.

Project Agorá: Connecting International Financial Institutions
Project Agorá is one of the most significant international experiments involving wholesale digital money.
Organised by the Bank for International Settlements (BIS) and the Institute of International Finance (IIF), the project brings together central banks and more than 40 financial institutions to investigate how tokenisation could improve cross-border payments.
Its approach combines tokenised commercial bank deposits with tokenised central bank reserves on a shared programmable platform.
This is important because international payments frequently involve several intermediary banks, separate payment systems and different operating hours. These processes can increase transaction costs, delay settlement and make it difficult to track payments.
Project Agorá is investigating whether a shared platform could reduce these inefficiencies while preserving the established two-tier monetary system.
Its prototype has demonstrated the feasibility of atomic settlement across currencies and jurisdictions. Atomic settlement means that connected parts of a transaction complete together on an all-or-nothing basis.
In July 2026, the project also conducted real-value testing involving 28 financial institutions and central banks. Transactions across selected currencies totalled approximately CHF 800,000.
The testing covered 17 transaction scenarios, including cross-border corporate payments, interbank transfers and payment-versus-payment transactions.
The average time from payment initiation to settlement was approximately 80 seconds during the exercise.
These results demonstrate the potential of tokenised financial infrastructure, although the prototype is not a finished commercial payment platform.
Project Agorá is particularly important because it explores how digital central bank money and commercial bank deposits could work together rather than treating them as competing forms of money.

United Kingdom: The Digital Pound Lab
The Bank of England has been investigating a potential digital pound through its digital pound design programme and industry experimentation.
The objective is to understand whether a digital form of sterling could provide useful payment functionality for households and businesses while preserving public access to central bank money.
The Digital Pound Lab has provided an experimental environment in which the Bank and participating organisations could investigate possible payment journeys and financial applications.
Its experiments have covered everyday retail payments, offline transactions, access to cash, trade finance and emerging forms of digital commerce.
The Bank reported that the Lab’s 12-month operational period had concluded, with more than 30 use cases and payment journeys developed across two phases.
Importantly, the Lab was not a live CBDC payment service. It used a simulated environment, involved no real customers and did not process payments using real money.
The wider digital pound programme is also considering the potential implications for financial stability, privacy, competition and the relationship between central bank money and commercial bank deposits.
As of November 2026, no final decision has been made to introduce a digital pound.
The UK’s approach demonstrates that central banks can use online experimental platforms to assess the commercial and technical feasibility of digital money before committing to a full implementation.

Project mBridge: Exploring Multi-Currency Digital Settlement
Project mBridge provides another important example of international experimentation with CBDC infrastructure.
The initiative involved the BIS Innovation Hub, the Hong Kong Monetary Authority, the Bank of Thailand, the Digital Currency Institute of the People’s Bank of China and the Central Bank of the United Arab Emirates. The Saudi Central Bank also joined the project.
Its objective was to investigate how multiple central bank digital currencies could operate on a shared distributed ledger platform to support cross-border payments and settlement.
The project reached its minimum viable product stage in mid-2024. It demonstrated the potential for participating central banks and commercial banks to exchange digital currencies through a common infrastructure.
The platform was designed to address some of the inefficiencies associated with international payments, including high transaction costs, lengthy processing times and complex intermediary arrangements.
Although the BIS project is now listed as concluded, its experimental work remains relevant to the development of future multi-currency payment infrastructure.
mBridge also illustrates the importance of international cooperation when designing digital financial systems. A platform operating across national borders must accommodate different regulatory requirements, settlement arrangements and monetary policies.

How Blockchain and Online Platforms Support CBDC Development
The development of CBDCs is closely connected to improvements in blockchain infrastructure, distributed ledger technology and financial software.
These technologies provide potential ways to record transactions, manage digital assets and coordinate payments between different financial institutions.
However, not every CBDC requires blockchain technology. Central banks can also use conventional database infrastructure or hybrid architectures depending on their requirements.
Distributed Ledger Technology
Distributed ledger technology allows authorised participants to access and update a shared record of transactions.
In a financial environment, this can improve transparency between participating institutions and reduce the need for separate records maintained by different organisations.
For wholesale CBDCs, distributed ledgers may support the exchange of tokenised deposits and central bank reserves.
Projects such as Drex and Agorá demonstrate how these systems can be used to investigate financial transactions involving multiple assets and institutions.
Smart Contracts and Programmable Payments
Smart contracts allow predefined conditions to trigger actions within a digital financial system.
For example, a securities transaction could be structured so that payment is released automatically once the required asset transfer has been confirmed.
This could reduce manual administration and improve coordination between financial institutions.
However, programmability must be implemented carefully. Financial systems require clear rules governing transaction approval, legal obligations and the correction of errors.
Digital Wallets and Payment Applications
Retail CBDC ecosystems require accessible applications through which individuals and businesses can hold and transfer digital currency.
These applications may be developed by banks, fintech companies or other authorised payment providers.
The digital euro and India’s e₹ demonstrate how central banks can work with third-party providers to deliver digital payment services.
This creates opportunities for financial technology businesses specialising in identity verification, wallet management, payment processing and cybersecurity.
Interoperability Between Financial Networks
Interoperability is essential if CBDCs are to operate effectively alongside existing payment systems.
A digital currency platform must be capable of communicating with banking infrastructure, merchant payment systems and potentially other national digital currency networks.
Without interoperability, CBDCs could create fragmented financial ecosystems that make payments more complicated rather than improving them.
Projects such as Agorá are investigating how shared infrastructure and common standards could support international transactions without removing the ability of individual central banks to manage their own currencies.
How CBDCs Could Influence Monetary Policy
The introduction of central bank digital currencies could have significant implications for monetary policy.
Monetary policy traditionally operates through the banking system, with central banks influencing interest rates, liquidity and credit conditions.
CBDCs could change how money moves between individuals, commercial banks and central banks.
Changes to Bank Deposits and Liquidity
One of the most important concerns is the potential movement of deposits away from commercial banks.
If consumers can hold digital money directly backed by a central bank, they may transfer some of their commercial bank deposits into CBDC wallets.
During periods of financial uncertainty, this could accelerate withdrawals from commercial banks and increase pressure on their funding and liquidity positions.
Central banks are therefore considering design safeguards, including holding limits and arrangements that connect CBDC wallets with commercial bank accounts.
The objective is to make digital money accessible without creating unnecessary disruption to the banking system.
Monetary Policy Transmission
CBDCs could influence how changes in central bank interest rates affect financial markets and consumers.
For example, a remunerated CBDC could potentially provide another channel through which changes in policy rates influence household and business financial decisions.
However, many proposed retail CBDCs are designed primarily as digital cash rather than interest-bearing savings products.
Their impact will therefore depend heavily on their remuneration arrangements, holding limits and relationship with commercial bank deposits.
The IMF has highlighted potential effects on money velocity, bank deposit disintermediation, reserve volatility and capital flows as important considerations when assessing CBDC design.
Faster Payments and Financial Liquidity
Wholesale CBDCs could improve the movement of money between financial institutions.
Faster settlement may reduce the time funds remain tied up in pending transactions and improve the management of liquidity across financial markets.
For international businesses, this could make cross-border payments more predictable and reduce administrative costs.
Nevertheless, faster settlement also means that financial institutions must manage liquidity and operational risks across potentially longer operating hours.
The challenge for central banks is to encourage more efficient payments while preserving effective monetary and financial stability frameworks.
The Wider Implications for Financial Systems
CBDCs could influence more than the way individuals make payments. Their development may affect the structure of financial services and the relationship between public and private financial institutions.
Financial Inclusion and Access to Digital Money
CBDCs could provide an additional way for people to access digital payments, particularly where existing banking services are limited.
Digital wallets and simplified payment applications may help reduce barriers to participation in the formal financial system.
Offline functionality could also improve accessibility in areas with unreliable internet connectivity.
However, digital currency alone cannot solve financial exclusion. Access to smartphones, reliable electricity, digital literacy and appropriate identification arrangements remain important considerations.
Privacy and Data Protection
Privacy is one of the most sensitive issues surrounding CBDC development.
Digital payments can generate detailed information about individuals’ spending patterns, transaction histories and financial relationships.
Central banks must establish clear rules governing which organisations can access this information and how it can be used.
A successful CBDC ecosystem needs to balance privacy with legitimate requirements involving fraud prevention, anti-money laundering and regulatory compliance.
Public confidence will depend on transparent governance and appropriate safeguards.
Cybersecurity and Operational Resilience
CBDC platforms would become important components of national financial infrastructure.
They would therefore need to withstand cyberattacks, technical failures and operational disruptions.
Central banks and technology providers must consider secure identity management, encryption, system monitoring, access controls and recovery arrangements.
A major interruption to a widely used digital currency platform could affect payment activity across the wider economy.
Security and resilience must therefore be fundamental design requirements rather than features added after development.
Competition Between Banks and Fintech Companies
CBDCs could create new opportunities for payment providers, fintech businesses and software developers.
Banks may develop digital wallet services, while specialist technology companies could provide infrastructure, integration and compliance solutions.
However, the emergence of central bank digital money may also increase competition between financial institutions.
The long-term impact will depend on the distribution model chosen by each central bank and the extent to which private providers are permitted to participate.
The Challenges Facing CBDC Platforms
Despite the potential benefits, CBDC projects face several significant obstacles.
Public adoption and user experience
Consumers already have access to established payment applications, debit cards and online banking services. A CBDC must provide a clear advantage if people are expected to adopt another payment option.
Regulatory and legal requirements
CBDCs raise questions about legal tender, consumer protection, financial privacy and the responsibilities of payment providers. These requirements vary across jurisdictions and can complicate international implementation.
Technology integration
Central banks must ensure that new digital currency infrastructure can communicate with existing banking and payment systems. Poor integration could increase costs and create additional operational complexity.
Financial stability
Large-scale transfers from commercial bank deposits into CBDCs could affect bank funding and liquidity. Appropriate holding limits and distribution arrangements may be necessary to reduce these risks.
International interoperability
Cross-border CBDC transactions require cooperation between central banks, commercial banks and financial regulators. Different currencies, legal systems and technical standards make this particularly challenging.
These issues demonstrate why pilot programmes are important. They allow central banks to identify potential problems before committing to nationwide or international deployment.
How Professionals Can Prepare for the CBDC and Digital Finance Economy
The development of CBDCs is creating demand for professionals who understand both financial systems and emerging digital technologies.
Traditional knowledge of banking, accounting and financial markets remains important, but professionals increasingly need to understand blockchain infrastructure, payment technologies and digital asset regulation.
Develop Blockchain and Distributed Ledger Skills
Learning how distributed ledgers operate provides a useful foundation for understanding CBDC platforms.
Professionals should become familiar with transaction validation, digital wallets, tokenisation and smart contracts.
Practical knowledge of these technologies can support careers in financial technology, blockchain development and digital payment infrastructure.
Understand Banking and Monetary Policy
CBDCs are fundamentally connected to the monetary system.
Professionals working in finance should understand central bank reserves, commercial bank deposits, liquidity management and the transmission of monetary policy.
These skills help explain why CBDC design decisions can influence financial stability and the wider economy.
Build Knowledge of Cybersecurity and Financial Regulation
Digital currency platforms require strong security and regulatory controls.
Skills in identity verification, data protection, financial compliance and cybersecurity are increasingly valuable across digital banking and payment services.
Professionals should also understand the regulatory differences between jurisdictions, particularly where international transactions are involved.
Learn Through Online Financial Technology Courses
Online learning offers a practical way to develop digital finance skills without committing to a lengthy academic programme.
Courses covering blockchain, digital assets, financial technology and monetary policy can help learners understand the technologies and economic principles shaping the CBDC market.
As central banks continue experimenting with digital currencies, professionals who combine financial knowledge with technical understanding will be better positioned to identify emerging opportunities.

Final Thoughts
Central bank digital currencies are moving beyond theoretical research into practical experimentation. Projects such as the European digital euro, India’s e₹ and Brazil’s Drex demonstrate how central banks are exploring new approaches to digital payments, while Project Agorá and mBridge highlight the potential of tokenised central bank money for international financial transactions. The UK’s Digital Pound Lab also demonstrates how experimental platforms can help assess the feasibility of future payment systems before decisions about implementation are made. Although these projects have different objectives, they share an interest in improving financial infrastructure, payment efficiency and the accessibility of digital money.
For financial institutions, CBDCs could create opportunities involving blockchain technology, payment processing, tokenisation and automated settlement. However, their development also introduces important questions around monetary policy, commercial bank deposits, cybersecurity, privacy and financial stability. For professionals, this creates a growing need for skills in digital finance, financial regulation, blockchain development and monetary economics. As pilot programmes continue to evolve, understanding the relationship between central bank money and emerging digital platforms will become increasingly valuable. The future of digital currencies will depend not simply on technological innovation, but on whether these systems can deliver secure, accessible and trusted financial services.
