Circle has formally responded to the European Commission’s consultation on reviewing the Markets in Crypto-Assets Regulation (MiCA), urging significant changes to how stablecoin reserves are managed. The issuer of USDC and EURC argues that while MiCA established a regulatory perimeter, it failed to capture the largest global tokens, noting that only three of the top 25 stablecoins by market value are currently MiCA-regulated. To address this, Circle recommended preserving "multi-issuance" structures, which allow globally circulating tokens to be co-issued by EU-authorized entities alongside foreign counterparts, warning that restrictions would push activity offshore.

The company’s most critical requests concern reserve composition. Current MiCA rules require e-money token issuers to hold at least 30% of reserves in commercial bank deposits, rising to 60% for tokens deemed "significant." Circle contended that this mandate increases exposure to banking-sector credit risk and aligned with the European Central Bank in calling for its replacement with flexible liquidity requirements. Additionally, Circle asked regulators to remove the 35% cap on single-sovereign exposure and limits on holdings at any one bank, stating these constraints force large issuers to spread reserves across dozens of institutions. This submission precedes a broader MiCA overhaul expected in 2027, occurring amidst a wider U.S.-EU contest over stablecoin dominance.
