EU central banks push tighter stablecoin rules

TLDR

EU central banks want MiCAs stablecoin regime tightened around rewards and yield, while loosening how reserves are held to reduce banking stress risk.

1. Central banks propose keeping the ban on stablecoin interest and extending it to indirect perks and yield from lending, borrowing and staking.
2. They also want to scrap fixed bank deposit quotas for reserves in favor of liquidity thresholds, changing how issuers structure backing portfolios.
3. The proposals feed into the European Commissions MiCA review, with final decisions and possible legislative changes expected over the next review cycle.

Deep Dive

1. What Central Banks Are Asking For

In a recent response to the MiCA review, the European System of Central Banks (ESCB) urged the EU to keep the existing prohibition on paying interest on stablecoins and to extend it to indirect incentives such as rewards, fee reductions and loyalty benefits. They also want yield from crypto lending, borrowing and staking to be treated as banned interest to prevent workarounds, arguing that electronic money should be used for payments, not saving.

These proposals build on MiCAs current rules, which already bar issuers and service providers from paying interest and have led some reward programs to shut down in Europe, as summarized in community coverage of the ESCB response on CoinsKid.

2. Changes To Reserve Rules And Market Impact

Central banks simultaneously propose scrapping MiCAs requirement that issuers hold at least 30 percent of reserves in bank deposits, or 60 percent for the largest significant stablecoins, and replacing it with liquidity based thresholds. The idea is to ensure enough assets mature within one to five working days so issuers can meet redemptions without rapidly pulling deposits from banks, which could destabilize lenders in a run.

For issuers like Circle (USDC, EURC), which has publicly argued that fixed deposit floors heighten exposure to bank credit risk and reduce flexibility, a liquidity based regime could allow more short term government paper and fewer low yielding deposits in reserve portfolios, as outlined in its MiCA response reported by Cointelegraph. For users and DeFi platforms in the EU, the tighter stance on rewards and yield would make regulated payment stablecoins much less compatible with savings or staking style products, pushing those activities offshore or into non MiCA regimes.

3. Timeline And What To Watch Next

The central bank proposals feed into the European Commissions formal MiCA review, whose consultation has just closed and will inform a broader reassessment of crypto rules, with media reporting that a full revision is expected around 2027. The Commission, not the central banks, ultimately decides whether to keep, tighten or relax the rules.

Key things to monitor are: whether the Commission adopts the extended interest ban, how it designs any new liquidity standards, and whether it opens space for cross border co issuance models that might keep major global stablecoins inside MiCA rather than pushing them out of the EU market.

Conclusion

EU central banks are pushing to keep stablecoins tightly constrained as low risk payment tools, especially around rewards and yield, while modernizing reserve rules to focus on liquidity rather than fixed bank deposits. If the European Commission largely follows their recommendations, euro stablecoins could become safer and more bank friendly but less attractive as income or DeFi building blocks, which would shape where European crypto users and builders look for stablecoin based products.
