Central banks’ experiments with central bank digital currency will reconfigure technical rails, legal boundaries, and market incentives that underpin payments. Agustín Carstens, Bank for International Settlements, has emphasized that design choices determine whether a CBDC strengthens public-money provision or unintentionally disintermediates banks. Those choices—retail versus wholesale, account-based versus token-based, interoperable versus siloed—drive downstream impacts on fintech systems and competition.
Payment infrastructure
At the systems level, CBDC adoption encourages modernization of settlement layers and interoperability protocols. Raphael Auer, Bank for International Settlements, has argued that wholesale CBDC models can streamline interbank settlement and cross-border transactions by shortening finality and reducing counterparty risk, while retail CBDC may require new interfaces for identity, privacy, and offline capability. Fintechs that currently build on card rails and ACH systems will need to integrate with central-bank led APIs and token standards, shifting engineering effort from proprietary clearing logic to secure direct access and standardised messaging. This transition can lower latency and operational costs for payments but also raises cybersecurity and resilience requirements for third-party providers.
Competition and market structure
Competition effects depend on the institutional model. Eswar Prasad, Cornell University, notes that a direct-access CBDC risks deposit outflows from commercial banks in stressed times, creating funding pressures that could shrink credit supply unless mitigated by two-tier frameworks or limits on holdings. Conversely, an intermediated CBDC model preserves commercial bank roles while offering fintechs new rails to innovate on front-end services. Programmability of CBDC can spur novel business models—automated escrow, conditional transfers, and micropayments—benefiting digital platforms and local economies, especially in regions with weak banking penetration. Cultural and territorial factors matter: jurisdictions with large informal sectors or extensive remittance flows may see faster uptake and distinct use patterns compared with advanced economies.
Regulatory responses will shape winners and losers. Clear rules on data protection, access, and anti-money-laundering will determine whether incumbent banks, BigTech, or nimble fintechs capture value from CBDC-enabled services. The Bank for International Settlements and central bank practitioners stress that preserving monetary sovereignty and financial stability while enabling innovation requires coordinated design, robust legal frameworks, and ongoing engagement with the private sector and civil society.
