The International Monetary Fund has published guidance for policymakers assessing the legal foundations for central bank digital currencies, with a primary focus on retail CBDC and separate analysis of wholesale CBDC. The note advises jurisdictions to conduct comprehensive legal reviews and, where necessary, amend legislation before issuance. It does not recommend that jurisdictions issue CBDCs. For retail CBDC, legal frameworks should establish it as a direct central bank liability under any distribution model, clarify any currency and legal tender status, and explicitly authorize the central bank to issue it and operate or oversee the payment platform. Frameworks should also regulate intermediaries, protect users’ holdings from intermediary insolvency, allocate liability among central banks, providers and users, and address holding and transaction limits, fees, programmability, offline payments and settlement finality. For wholesale CBDC, authorities should clarify the legal relationship between tokens and underlying central bank reserves, ensure the central bank has authority to issue the instrument and control its platform, and define when transfers become irrevocable and final.
