Europe’s central banks want to scrap this stablecoin reserve safeguard

EU rules require stablecoins issued by electronic-money institutions to keep at least 30% of their reserves in commercial-bank deposits, rising to 60% for significant tokens. Britain's policy for systemic sterling stablecoin reserves excludes those deposits from coin backing. European central banks now want to remove the EU requirement, bringing the two approaches closer on the risk banks pose to stablecoin reserves.

Reuters reported on Sept. 22 that the European System of Central Banks, comprising the European Central Bank and EU national central banks, recommended replacing the compulsory bank-deposit share under the Markets in Crypto-Assets regulation with minimum reserve percentages in assets maturing within one and five working days. The proposal would change where issuers must keep redemption money; MiCA's existing requirements remain in force.

The same day marks the Bank of England's consultation deadline for its draft systemic stablecoin Code of Practice. Its June policy already ruled out commercial-bank backing because of financial, operational and contagion risks. The Bank intends to finalize the code by the end of 2026.

The regimes cover different types of issuer and are at different stages of implementation. Yet the recommendation points toward a shared concern: putting stablecoin reserves in banks can connect two sources of financial stress.
