Circle and Paxos gain MiCA edge as 3 stablecoins lead EU compliance

Circle's USDC and EURC, alongside Paxos's USDG, are the leading MiCA-compliant stablecoins in the European Union, a Circle executive said July 29, as the bloc's regulatory framework reshapes a $302 billion global stablecoin market.

"MiCA compliance grants Circle and Paxos a competitive edge in the EU, potentially reshaping stablecoin market dynamics and regulatory strategies," the executive said, according to a report from CryptoBriefing.

USDC holds a $75.3 billion market cap with 72 percent year-over-year growth, processing $11.9 trillion in on-chain volume during the fourth quarter of 2025 alone, per CoinGecko data. EURC commands over 50 percent of the MiCA-compliant euro stablecoin market with a $430.4 million market cap, growing 109.8 percent in the year ending June 2026. By contrast, Tether's USDT — the largest stablecoin at $183.6 billion — remains delisted from European exchanges after failing to obtain Electronic Money Institution authorization under MiCA.

The regulatory divergence creates a two-track market. USDC and EURC are positioned for institutional adoption in Europe, where compliance is a prerequisite for licensed trading. USDT retains dominance in unregulated and emerging markets, but its exclusion from the EU — combined with the US GENIUS Act signed in July 2025 — pressures Tether to adapt its offshore structure or cede market share in regulated jurisdictions.

MiCA's enforcement reshapes the competitive landscape

The EU's Markets in Crypto-Assets regulation required stablecoin issuers to obtain authorization by mid-2024, with the full transition period for crypto asset service providers closing July 1, 2026. Circle secured authorization as an Electronic Money Institution in France ahead of the deadline, positioning both USDC and EURC as compliant from the outset. Paxos followed with USDG, creating a three-token cohort that meets the bloc's reserve, transparency, and licensing requirements.

Hungary's recent regulatory shift illustrates the framework's impact. The Hungarian Parliament repealed a mandatory third-party crypto validator requirement after the rule disrupted the local market, while the National Bank of Hungary granted CoinCash the country's first MiCA license on July 20, according to a company announcement.

$185 billion in USDT supply locked out of Europe

The compliance gap has real market consequences. MiCA enforcement left roughly $185 billion in USDT supply unavailable on licensed European trading venues, pushing EU retail traders toward USDC and EURC, according to data from CoinGecko and DefiLlama. The total market cap of MiCA-compliant euro stablecoins surged 128 percent from $295.6 million to $673.9 million between June 2025 and June 2026, with only eight tokens meeting full requirements.

For Circle, the regulatory moat translates into commercial momentum. The company's fourth-quarter 2025 revenue reached $770 million with EBITDA surging 412 percent, driven by institutional adoption from Visa, Mastercard, and BlackRock integrating USDC for payment settlement.
