Circle Hears Europe's Knock While USDT Pretends Not to Be Home 🚪

Circle is positioning itself as the primary beneficiary of the European Union's Markets in Crypto-Assets (MiCA) regulation, which reached its final compliance deadline on July 1. Licensed exchanges across the bloc have begun delisting Tether's USDT, clearing a path for Circle's USDC to capture share on regulated venues. Of the top ten stablecoins by market capitalization, Circle is the only issuer that secured e-money-token authorization under MiCA for both USDC and its euro-denominated EURC.

Tether did not apply for the MiCA license. CEO Paolo Ardoino has defended the decision publicly, citing the regulation's requirement that issuers hold 60% of e-money token reserves in European bank deposits, a structure Tether declined to adopt. As a result, USDT's roughly $185 billion in circulation is no longer available on EU-licensed exchanges. Tether has indicated it will continue serving markets outside the European Union.

Circle co-founder and CEO Jeremy Allaire framed the moment on social media on June 30, 2026, writing: "Stablecoins represent one of the largest market opportunities in the world as the internet transforms the infrastructure for storing and moving money. We deeply believe in this, and it's why we both founded Circle and why we've invested to build the largest regulated stablecoin…" The post appeared as Allaire's account, @jerallaire.

Institutional infrastructure is reinforcing the shift. On June 30, BNY (Bank of New York Mellon) confirmed that USDC became the first stablecoin available on its Digital Asset Custody platform, allowing institutional clients to store, transfer, mint, and burn USDC through the bank. The move adds a major U.S. custodian to Circle's distribution at the same moment European exchanges are restricting access to competitors.

The broader regulatory transition is reshaping the EU crypto sector. Of the approximately 1,200 virtual-asset firms that held pre-MiCA national registrations across the bloc, only around 210 converted to full Crypto-Asset Service Provider (CASP) authorization, a rate near 17%. Tether has not signaled plans to seek MiCA approval, and the degree to which EU trading volume migrates to USDC is set to become clear in the coming weeks.
