Europe's Central Banks Just Sided With Stablecoins Against Europe's Own Rulebook
The most surprising stablecoin opinion in Europe this week came from the continent's central bankers. The European System of Central Banks, the ECB plus the 27 national central banks, published a 57 page response to the European Commission's review of MiCA on Tuesday, and in it the group argues that one of MiCA's signature safety rules should go. The rule requires stablecoin issuers to hold 30 percent of reserves as bank deposits, rising to 60 percent for significant issuers. The central banks say that requirement creates a direct link between issuers and credit institutions, and could leave lenders exposed to sudden withdrawals if a stablecoin run forces an issuer to pull deposits fast.
Their proposed replacement shifts the question from where reserves sit to how fast they turn into cash. Pointing to draft European Banking Authority standards, the central banks back minimum liquidity thresholds, with significant stablecoins holding at least 40 percent of reserves in assets maturing within one working day and 60 percent within five working days, and lower thresholds of 20 and 30 percent for the rest. Overnight reverse repurchase agreements and short term sovereign bonds get a nod as the kind of instruments that fit the new buckets.
The irony here has a history. Tether CEO Paolo Ardoino has argued since at least 2024 that MiCA's bank deposit requirements tie banks and issuers together in unhealthy ways. This week the central banks effectively agreed with him, which is a remarkable alignment between the industry's loudest critic of the rule and the institutions that write the rulebook. When the referee starts quoting the player who has been arguing the call for two years, the call is probably changing.
The paper goes further on a second front, rewards. The ESCB wants crypto platforms prevented from using lending, borrowing, staking, or other products that generate indirect returns on stablecoin holdings, extending the existing stance against direct remuneration. The group's position is that electronic money exists for payments, a tool for spending rather than a place to park savings, and that layered yield structures could blur the line between electronic money and bank deposits while tilting competition across the EU financial system. It is the same fight American banks just waged over the CLARITY Act, where eight banking groups pushed senators to tighten reward restrictions before the bill stalled on a 49 to 50 procedural vote.
There is also a candid enforcement note tucked into the response. The central banks describe material challenges in enforcing MiCA, with firms operating outside the rules still reaching EU customers, raising concerns over investor protection and market integrity. A rulebook is only as strong as its reach, and the ESCB just said the reach needs work.
For stablecoin holders and builders, the direction of travel is clarifying on both continents. Europe is moving toward liquidity based reserve rules that treat speed of redemption as the real safety metric, while drawing a firmer line around yield. The United States, meanwhile, watches its market structure bill sit in neutral while agencies write the rules case by case. Builders planning euro stablecoin products should design for liquidity buckets now, because the central banks just told everyone where the puck is going.
