ECB Pushes MiCA Overhaul: Replaces Fixed Bank-Deposit Floors with Liquidity Requirements
The European Central Bank and the EU's 27 national central banks have jointly called for MiCA to replace its 30% and 60% mandatory bank-deposit floors for stablecoin reserves with maturity-based liquidity requirements. The proposal comes as Britain's parallel systemic sterling stablecoin code enters its consultation phase.

ECB's Alternative to Fixed Deposit Mandates
The European System of Central Banks submitted a formal response requesting that MiCA's tiered reserve structure be overhauled. Under current MiCA rules, stablecoin issuers must hold 30% of reserves in highly-liquid bank deposits and 60% in a combination of deposits and short-term government securities. The ECB argues these fixed floors should be replaced with maturity-matched liquidity standards tied to redemption risk, rather than asset type mandates.
The central banks' position aligns with concerns Tether raised in 2024 about the rigidity of MiCA's reserve framework. Tether specifically flagged the inflexibility of the 30%-60% split as a structural constraint on stablecoin operations in the EU market.
Timing and Broader Regulatory Context
The ECB's submission comes as the UK's systemic sterling stablecoin code approaches the end of its public consultation period. Britain's proposed framework also sets reserve requirements but operates independently of EU regulation, creating a divergence in how the two jurisdictions approach stablecoin liquidity safeguards. The ECB's push to reform MiCA suggests European regulators view liquidity-based standards as more adaptive to market conditions than asset-specific percentages.
Why It Matters
For Traders
A shift from fixed deposit mandates to liquidity requirements could lower operational costs for stablecoin issuers active in EU markets, potentially affecting spreads and redemption terms.
For Investors
Maturity-based liquidity standards are more flexible than asset-type floors; approval could ease market entry for new EU-compliant stablecoins but may also signal regulatory acceptance of less conservative reserve models.
For Builders
Protocol teams designing EU-compliant stablecoins should track the ECB's final guidance on maturity matching; liquidity-based rules create different technical and economic tradeoffs than the current fixed-allocation regime.
