Banks Face Tests as Digital Money Advances

Central banks, payment networks and technology firms are running pilots of central bank digital currencies, stablecoins and tokenized deposits, testing whether banks can handle new payment rails and token-based assets. Trials have moved from research to limited rollouts in several countries.

China has expanded trials of the digital yuan across cities and merchant networks. The U.S. Federal Reserve funded Project Hamilton and launched the FedNow instant payment service in 2023. The European Central Bank and the Bank of England continue work on a digital euro and a potential digital pound. Wholesale experiments such as Project Jasper in Canada, Project Ubin in Singapore and Project Helvetia in Switzerland have tested tokenized securities and faster settlement between banks and market infrastructure.

Banks must update core systems that were built decades ago or add middleware to connect accounts and ledgers to token-based rails. Technical tasks include building interfaces to distributed ledgers, managing cryptographic standards and ensuring atomic settlement when tokenized assets and payments move together. Firms report plans to strengthen cybersecurity and operational-resilience measures to protect new API and ledger connections.

Compliance and legal issues are prominent. Banks must apply know-your-customer, anti-money-laundering and sanctions screening to tokenized flows. Privacy laws differ across jurisdictions, creating a need to reconcile ledger transparency with rules that protect customer data. Cross-border payments remain complex because there is no single global standard for CBDC interoperability and correspondent-banking links may need redesign if retail digital currencies or widely used stablecoins change intermediaries’ roles.

Liquidity and balance-sheet effects are under review. If retail CBDCs allow direct accounts at central banks, commercial banks could see deposit outflows that alter funding profiles and capital requirements. Several central banks have proposed designs that keep commercial banks as intermediaries for distribution and customer services. Wholesale tokenized CBDCs have reduced settlement risk and freed intraday liquidity in experiments, but they require coordinated changes to market infrastructure and collateral management.

Responses vary across the banking sector. Large global and regional banks have created teams to test tokenization, CBDC interfaces and new payments APIs. Some institutions are partnering with fintech firms to build wallet services and custody solutions. Others are investing in middleware to translate between legacy systems and ledger-based rails. Smaller banks and credit unions report higher costs for compliance and technology changes and often rely on third-party providers for retail wallet access or settlement gateways.

Regulatory frameworks remain unsettled. Jurisdictions are defining whether digital money will be legal tender, how it will be taxed and which entities may issue or operate wallets. Rules for privacy, consumer protection and dispute resolution for programmable payments are still under discussion. International organizations have published guidance, but final rules will be set by individual countries.

Central bank digital currency is a digital form of fiat money issued by a central bank. Retail CBDCs are intended for households and businesses; wholesale CBDCs support interbank settlement and other market functions. Stablecoins are privately issued tokens that aim to keep a stable value, usually pegged to a fiat currency. Tokenization means representing assets, including deposits and securities, as digital tokens that can move on ledger platforms.

Pilots, experiments and regulatory work are ongoing in multiple jurisdictions, and banks continue to adjust operations and connectivity to new payment rails.
