Circle obtains CASP approval under MiCA: USDC compliance channel officially opens across Europe

Since the phased implementation of the MiCA legislation in 2024, its core goal has been to incorporate crypto assets into a unified European regulatory framework. The CASP (Crypto Asset Service Provider) license is the most essential authorization category within this system for trading platforms, custody wallets, and transfer services. As the issuer of USDC, Circle’s European entity obtaining CASP approval signifies that USDC’s issuance, custody, and transfer activities in Europe have for the first time received consistent legal recognition across 27 member states. The significance of this milestone lies in solving the longstanding issue of “license fragmentation” in cross-border stablecoin operations. Under the MiCA framework, entities holding CASP authorization can provide services throughout the EU via the “passport mechanism,” without needing to apply separately in each country. This establishes a regulatory foundation for USDC’s liquidity and channel expansion in Europe.

How the competitive landscape between USDC and USDT will change after the compliance channels are opened

As of May 6, 2026, based on Gate’s market data, USDC is priced at 1.00 USD, and USDT is also at 1.00 USD. The two leading stablecoins are equally anchored in pricing, but the differentiation in compliance attributes is widening. The recent CASP authorization granted to USDC covers custody and transfer services, giving it a clear legal basis when serving European institutional clients, banking partners, and regulated trading platforms. In contrast, Tether, the issuer of USDT, has not disclosed progress toward equivalent comprehensive MiCA authorization across the entire region. This means that for European institutional funds requiring strict regulatory backing—such as insurance companies, asset managers, and payment institutions—USDC has gained a first-mover advantage in the regulatory system. It’s important to note that compliance does not automatically translate into market share transfer, but its advantages in reducing counterparty risk and meeting AML scrutiny will be significant factors when institutions choose custodial assets.

How the European unified market will reshape the liquidity structure of stablecoins

The core design of MiCA is “unified authorization and cross-border circulation.” In the stablecoin context, this means that USDC approved as a CASP can freely transfer among custodians in different jurisdictions such as Ireland, Luxembourg, Germany, and France, with highly consistent compliance review standards for each transfer. This structure impacts stablecoin liquidity in two ways: on one hand, it reduces compliance friction costs across jurisdictions, facilitating market makers to provide USDC liquidity on more European trading venues; on the other hand, it raises ongoing compliance requirements for stablecoin issuers, including reserve asset disclosures, operational capital maintenance, and transaction monitoring reports. From a market structure perspective, this arrangement favors larger stablecoin issuers with stronger compliance capacity, objectively increasing the potential for market concentration.

How traditional financial institutions can leverage MiCA amid the wave of bank entry into crypto

Fédération Générale du Crédit Agricole’s SG-Forge expanding its MiCA-compliant services is not an isolated event. Several European traditional financial institutions are applying for or have already obtained CASP-related licenses, typically through two pathways: one is establishing independent subsidiaries to apply for crypto service licenses; the other is partnering with already licensed compliant stablecoin issuers. For USDC, Circle’s CASP approval positions it as a natural custodian and transfer partner for banking institutions. When banks offer digital asset custody or compliant payment services, choosing stablecoins with clear compliance attributes can significantly reduce regulatory risks. Once this “bank + compliant stablecoin” model scales, it will promote USDC’s penetration from crypto-native scenarios into traditional financial infrastructure, transforming stablecoin use cases from mere trading media to compliant settlement assets.

Will regulatory compliance become a core barrier in stablecoin competition?

From the perspective of MiCA’s implementation logic, compliance is shifting from an “optional bonus” to a “market entry threshold.” Obtaining CASP approval involves multi-dimensional reviews including capital requirements, governance structure, client asset segregation, and transaction monitoring, typically taking 12 to 18 months or more. This means that after MiCA’s full rollout, stablecoins without clear compliance pathways will face substantial operational barriers in Europe—such as delisting from trading platforms, rejection by banks, or withdrawal by institutional clients. Consequently, the competition focus is shifting from on-chain technical performance (like transaction speed and gas fees) to institutional compliance capabilities. The approval USDC recently received is not only a license to operate but also a window of regulatory advantage for a period. Competitors unable to establish equivalent compliance frameworks in the short term will find it difficult to compete on equal footing in the European institutional market.

Is the stablecoin battlefield shifting from a crypto-native scene to a regulatory framework?

Historically, stablecoins have mainly been used in crypto trading pairs, DeFi liquidity pools, and cross-border personal transfers. Under MiCA, the gradual implementation of CASP approvals is pushing stablecoins into the institutional realm—including compliant settlement on regulated trading platforms, payment routing for financial institutions, corporate treasury management, and cash settlement layers for asset tokenization projects. A key signal of this trend is that USDC’s recent approval coincides with the expansion of bank-affiliated crypto service providers like SG-Forge, indicating that European regulators intend to bring stablecoins into the traditional financial compliance orbit. For crypto exchanges, this may lead to changes in user composition—an increase in institutional users and trading behaviors—along with higher demands for trading depth, settlement efficiency, and compliance reporting.

Summary

Circle’s obtaining of the MiCA CASP approval marks a pivotal event in Europe’s stablecoin regulation, signifying that USDC’s custody and transfer activities across the 27 EU countries now have unified legal recognition. In the short term, this enhances USDC’s first-mover advantage in the institutional compliance track; in the long term, it could reshape the competitive logic of the stablecoin market—from a focus on technological efficiency to one emphasizing institutional compliance. The entry of traditional financial institutions like banks further accelerates stablecoin’s infiltration into traditional financial infrastructure, shifting its use cases from crypto-native scenarios to regulated financial systems. Regulatory compliance is becoming a market entry threshold rather than an option for stablecoins.

FAQ

Q: What is the difference between CASP approval and a stablecoin issuance license?

CASP (Crypto Asset Service Provider) authorization covers services like custody, trading, and transfer. A stablecoin issuance license (under the EMT framework) pertains to the issuance activity itself. Circle’s recent approval as a CASP means it can legally provide USDC custody and transfer services in Europe.

Q: What is the current compliance status of USDT in Europe?

As of May 2026, Tether has not publicly disclosed obtaining equivalent comprehensive MiCA CASP authorization across the entire region. Its European compliance status depends on local arrangements with specific member states and does not yet have a unified passporting capability.

Q: What practical impact does compliance stablecoin have on ordinary users?

Compliant stablecoins are subject to higher regulatory requirements regarding custody security, reserve transparency, and fund traceability, allowing users to verify backing assets through public disclosures. However, in daily transactions and transfers, there is no significant difference compared to non-compliant stablecoins.

Q: Does CASP authorization under MiCA mean the EU recognizes stablecoins as legal currency?

No. Under MiCA, stablecoins are classified as crypto assets and are not considered legal tender. Their issuance and operation are regulated but do not confer legal status as currency.

Q: How will this event affect USDC’s trading depth in Europe?

The opening of compliance channels benefits more European compliant trading platforms and market makers to participate in USDC liquidity provision. Long-term, this could enhance trading depth, but it depends on the actual demand growth for compliant stablecoins in the region.
