OKX Europe has expanded its conversion capabilities by launching one-way conversion routes across 30 EU and EEA countries, allowing customers to deposit USDT and exchange it for MiCA-compliant USDC and USDG. According to latest reports, the platform now fully supports USDC (issued by Circle) and USDG (issued by Paxos) for deposits, trading, and related services including the OKX Card. The company has introduced an 8% deposit bonus for assets moved from non-MiCA platforms starting from the enforcement of new regulations. Unlike automatic conversion programs, OKX's service allows users to decide when to exchange their holdings, with the conversion remaining at the client's discretion. The distinctive feature is that the conversion remains at the client's discretion, with no deadlines imposed by the platform.
The conversion launch comes ahead of the July 1, 2026 deadline when licensed platforms in the EU will no longer be permitted to offer non-compliant stablecoins to European users. European platforms have significantly reduced support for USDT since Tether has not secured authorization to issue the stablecoin under MiCA. As reported by CoinDesk, since the regulation's final transition period ended on July 1, 2025, exchanges have restricted deposits, removed trading pairs and directed customers toward approved alternatives. Circle's USDC has become a main option because it operates under the EU framework, with OKX's new tool supporting deposits only in USDT and conversions only into USDC. The shift follows the completion of MiCA's stablecoin rollout, turning stablecoin access in Europe from a liquidity question into a licensing question.
Circle's EURC stablecoin has gained over $110 million in market cap this year, doubling to roughly $430 million as MiCA regulations reshape Europe's stablecoin landscape. The token's circulation now sits at approximately €378 million as of mid-July, with its share of the euro stablecoin market ballooning from about 17% a year ago to north of 40%. The broader euro stablecoin market has reached record highs approaching $900 million as of mid-2026, with EURC commanding roughly 40–50% of that total. Circle secured a French Electronic Money Institution license back in 2024, giving it a single regulatory passport to operate across the entire EU and European Economic Area. The supply numbers tell the story clearly, with EURC's token supply growing from roughly 309 million at the end of 2025 to approximately 390 million in early 2026, nearly tripling in a compressed timeframe.
Despite European restrictions, USDT remains the world's largest stablecoin with Tether controlling about 59% of the nearly $310 billion stablecoin market, according to DefiLlama data. As reported by CoinDesk, USDT holds roughly $184 billion in market value, compared with around $73 billion for USDC. However, USDT trading volumes on EU platforms have already dropped significantly, with some exchanges reporting declines exceeding 70%. Revolut has announced plans to stop supporting USDT for customers in the EEA and Switzerland, giving users until August 31 to sell or withdraw their holdings before Revolut converts any remaining tokens into base currency. The larger market implication is that stablecoin dominance is no longer measured only by market capitalization - regulatory access is becoming a second measure of strength.
Tether CEO Paolo Ardoino has repeatedly defended the company's decision not to seek MiCA authorization, arguing that the framework's reserve rules could expose stablecoin issuers to additional risks. In an interview, Ardoino described the regulatory framework as "very dangerous with respect to stablecoins", specifically questioning the reserve requirements that oblige issuers to hold a portion of their funds in European credit institutions. In a July 2025 post on X, Ardoino said Tether would reconsider seeking authorization only "when MiCA becomes safer for consumers and stablecoin issuers." The company's objection centers on reserve requirements under the framework, including rules that require a portion of reserves to be held with European credit institutions.
