ECB Blocks Euro Stablecoin Relief as FDIC and Japan Tighten Rules
The stablecoin sector hit a fresh all-time high of $323.052 billion this week, and regulators on three continents responded not with celebration but with new restrictions. The ECB shot down proposals to ease rules for euro stablecoin issuers, the FDIC advanced Bank Secrecy Act compliance requirements for bank-linked issuers in the US, and Japan finalized a sweeping overhaul of its payment and crypto intermediary rules effective June 1. All three moves point in the same direction: stablecoins are getting bigger, and regulators are not letting that go unmanaged.
ECB Draws a Hard Line in Nicosia
At an informal Ecofin meeting in Cyprus, Brussels think tank Bruegel put forward a proposal to loosen liquidity requirements for euro stablecoin issuers and potentially grant them access to ECB funding. The ECB rejected it outright. ECB President Christine Lagarde led the pushback, warning that stablecoin issuance destabilizes bank deposits by funneling funds to issuers’ accounts, raising bank funding costs and eroding interest-rate transmission. She had already stated publicly that “the case for promoting euro-denominated stablecoins is far weaker than it appears.”
Bruegel’s argument was a competitiveness one: Europeans execute 38% of global stablecoin transactions, yet euro-denominated tokens account for just 0.3% of total supply. Circle’s EURC, the largest euro stablecoin, ranks only 12th globally. The think tank warned that stricter EU rules compared to the US GENIUS Act risked accelerating dollar dominance in digital payments. Central bankers at the meeting largely dismissed that concern. Several even floated restrictions on European redemptions of both US and EU-issued stablecoins to guard against reserve runs. The ECB is not treating euro stablecoins as a competitive opportunity; it is treating them as a threat to the deposit base.

In the US, the FDIC board advanced a proposed rule that would impose Bank Secrecy Act and sanctions compliance standards on FDIC-supervised stablecoin issuers, including anti-money laundering oversight and Treasury Department consultation requirements. The measure sits within the broader GENIUS Act implementation framework, and its timing is notable given that US banks have been pushing back against stablecoin provisions for months. The FDIC is now making clear that any bank-linked issuer will carry a full compliance load, not a lighter crypto-native one.
Japan’s FSA finalized its own package simultaneously, covering trust-type stablecoin reserves, a new intermediary business category for crypto and payment services, and cross-border payment structures. The rules take effect June 1, giving affected firms almost no runway to adjust. Reserve assets for certain instruments may now include government bonds and cancellable fixed-term deposits alongside demand deposits, but the FSA paired that flexibility with strict allocation ratios and safeguards against principal loss. The agency received 259 comments from 62 entities during consultation, which tells you the industry was paying close attention.
Back in the market, Tether holds $189.468 billion of the $323 billion total, a 58.65% share. The top five stablecoins collectively account for nearly 90% of the sector. That concentration should worry anyone counting on competition to discipline the market. Regulators are building compliance frameworks around a sector that is already dominated by two or three players, and the ECB’s refusal to ease euro rules guarantees that dollar-denominated tokens keep that structural advantage. Whether Washington, Tokyo, or Brussels intended to entrench Tether’s position is irrelevant. That is the outcome on the table.
