How Will the US GENIUS Act Reshape the Stablecoin Landscape? Comparing MiCA and Global Regulatory Convergence

2026 年 has become a critical turning point in the global regulation of stablecoins, shifting from textual legislation to substantive enforcement. The US GENIUS Act is entering a period of intensive rulemaking, while the EU MiCA framework has fully entered the enforcement phase. Although they belong to different jurisdictions and adopt different legislative logics, they show significant convergence in core regulatory dimensions. This convergence is no coincidence—stablecoins, as the core infrastructure of digital payments, are being globally aligned into a normative system based on “reserves transparency, compliant authorization, and financial stability.”

What is the key time window for US legislation?

The legislative and enforcement process of the US GENIUS Act is in a critical sprint phase. The bill was signed into law by the president on July 18, 2025, establishing the first federal regulatory framework for payment-type stablecoins in the US. According to the bill, all federal regulators overseeing payment stablecoins must issue final implementation rules by July 18, 2026, and the law will fully take effect 120 days after the final rules are published or by January 18, 2027. This schedule means July 2026 is a hard deadline for the release of regulatory details.

On the regulatory rule level, OCC released a comprehensive 376-page proposal in February 2026, FDIC introduced prudential regulation rules in April of the same year, and FinCEN and OFAC jointly issued proposed rules on AML and sanctions compliance on April 8. Meanwhile, the White House set a legislative goal to push the CLARITY bill for signing before July 4. The coordinated advancement of these two bills is shaping the regulatory landscape for digital assets in the US.

What rigid constraints does the MiCA enforcement phase face?

Unlike the US, which is still in the rulemaking stage, the EU MiCA framework has entered the enforcement cycle. Since the comprehensive application of stablecoin provisions in June 2024, the entire market faces a rigid compliance bottom line: by July 1, 2026, all stablecoin issuers operating in the EU must obtain formal authorization, or face delisting. This leaves less than two months before the deadline.

In this context, early movers with compliance advantages are emerging. Circle France received MiCA authorization from the French AMF on April 20, 2026, allowing it to provide custody and transfer services for USDC and EURC across the European Economic Area. Meanwhile, Tether’s USDT has been deemed non-compliant by major EU trading platforms because it has not obtained the necessary licenses and its reserve disclosure system does not meet MiCA standards. This enforcement mechanism shows that MiCA is not just a paper framework—its rigid enforcement is actively changing the supply structure of stablecoins in Europe.

What are the mirror logics behind reserve, licensing, and yield bans?

Although the GENIUS Act and MiCA differ in legislative pathways and regulatory divisions, they show high mirror characteristics in three core regulatory dimensions.

In reserve requirements, both establish the basic principle of 1:1 full reserves, requiring high-liquidity assets to support stablecoin value. The GENIUS Act explicitly mandates issuers to maintain 1:1 reserves and publish audited reserve composition reports monthly. MiCA also requires full reserves for electronic money tokens (EMT) and prohibits paying interest to holders.

In licensing systems, the GENIUS Act sets three pathways for issuance—subsidiaries of depository institutions, OCC-approved federal qualified issuers, and state-licensed state qualified issuers—creating a “bank-level” access threshold. MiCA restricts EMT issuance rights to credit institutions or electronic money institutions authorized within the EU, following the principle of “same business, same risk, same regulation.”

In yield bans, both impose clear restrictions on the yield-generating attributes of payment-type stablecoins. The GENIUS Act explicitly prohibits stablecoin issuers from paying interest or yields to holders. MiCA similarly bans electronic money tokens from paying interest. Both bills tend to define payment stablecoins as pure exchange and settlement tools, not as financial assets generating returns, to prevent their evolution into “internet-scale shadow deposits.”

What deeper compliance integration exists beyond competition?

Building on the convergence in the three core dimensions, the GENIUS Act and MiCA also show deep integration of compliance logic at a macro level. The US Treasury’s rulemaking explicitly requires assessing whether state-level regulatory frameworks are “substantively similar” to federal ones, essentially constructing a unified regulatory baseline. MiCA establishes a single passport system in Europe, allowing issuers authorized in one country to operate freely across the European Economic Area.

This convergence also reflects a structural change in cross-border compliance costs. When a stablecoin issuer’s reserve management and AML compliance systems simultaneously meet the bank-level standards of the GENIUS Act and the electronic money institution standards of MiCA, the marginal compliance costs of cross-jurisdictional operations are significantly reduced. The overlapping frameworks in reserve transparency, customer due diligence, and sanctions screening are creating conditions for the emergence of a global compliance infrastructure.

How are institutional capital and tokenization infrastructure responding to regulatory signals?

The certainty of the regulatory framework is driving real institutional capital inflows. Wall Street’s response is particularly swift. JPMorgan has launched the on-chain liquidity fund JLTXX, designed to meet the reserve standards of the GENIUS Act, marking a proactive move by traditional asset managers to tokenize reserve management tools. BlackRock has also submitted applications for two tokenized funds, aiming to bring its large-scale stablecoin custody business fully on-chain.

In Europe, the Qivalis alliance of major banks is advancing a euro stablecoin compliant with MiCA, expected to launch in the second half of 2026. ING, UniCredit, and BNP Paribas are jointly developing a euro stablecoin based on Ripple blockchain technology. This indicates that compliant frameworks are not stifling innovation—instead, they are providing clear institutional pathways for traditional financial institutions to enter the stablecoin space.

What is the future direction of the global regulatory landscape?

The standards set by the Bank for International Settlements and the Financial Action Task Force are providing higher-level regulatory anchors for the GENIUS Act and MiCA. Both bills’ provisions on AML, counter-terrorism financing, and reserve management draw on these international standards.

However, differences remain. The GENIUS Act emphasizes federal and state regulatory coordination, while MiCA favors a centralized single passport mechanism. Regarding decentralized stablecoins, the structural premise of the GENIUS Act—requiring identifiable issuers—effectively excludes protocols without clear issuers from regulation; whereas MiCA, through functional definitions, covers decentralized stablecoins but imposes technical compliance barriers that functionally amount to a de facto ban. These differences suggest that in the short term, global regulation will evolve mainly through “policy alignment” rather than “institutional unification.”

Summary

In the first half of 2026, the GENIUS Act and MiCA jointly established the first substantive frameworks for global stablecoin regulation. Their reserve requirements, licensing systems, and yield bans are highly convergent at the core level, but they retain distinct features in enforcement mechanisms and scope of application. This pattern of “core convergence, detailed divergence” determines that global compliance infrastructure will evolve along two main tracks, paralleling each other, and continue to align in areas like reserve custody, compliance auditing, and AML technology at a macro level.

By 2026, the global stablecoin compliance framework has shifted from “legislative competition” to “enforcement implementation.” The rulemaking of the GENIUS Act and the strict enforcement of MiCA form the two main axes of today’s global stablecoin regulation. The core convergence (reserve 1:1 + yield ban + bank-level compliance) and the detailed differences (decentralized stablecoin handling, federal/single passport mechanisms) jointly shape the distribution of compliance costs. Early movers will gain significant first-mover advantages, while issuers failing to meet standards face systemic risks of exit from regional markets.

FAQ

Q1: How do the reserve requirements of the GENIUS Act and MiCA compare?

Both require payment stablecoins to maintain 1:1 full reserves, supported by high-liquidity assets (cash, short-term US Treasuries, etc.), and to disclose audited reserve reports regularly. Differences lie in the specific qualified assets and regulatory acceptance standards.

Q2: What does July 1, 2026, mean for the stablecoin market?

This date is the hard deadline for full enforcement of the EU MiCA regulation. Issuers without official authorization will be forced to exit the EU market, sharply dividing compliant and non-compliant stablecoins.

Q3: What is the rationale behind the prohibition of yield payments in the GENIUS Act?

The yield prohibition aims to prevent payment stablecoins from evolving into “shadow deposits,” avoiding direct competition with traditional bank deposits, and maintaining financial stability. It is also a key point of contention between banking and crypto sectors.

Q4: How can stablecoin issuers meet both regulatory systems simultaneously?

By building compliant infrastructure that is compatible with the GENIUS Act’s bank-level reserve standards and MiCA’s electronic money institution standards—including unified reserve management, AML procedures, and disclosure systems—issuers can reduce the marginal compliance costs of cross-jurisdictional operations.

Q5: What is the legal status of decentralized stablecoins under both frameworks?

The GENIUS Act’s structural premise—requiring identifiable issuers—effectively excludes protocols without clear issuers from regulation. MiCA, through functional definitions, includes decentralized stablecoins but imposes technical compliance barriers that amount to a de facto ban. Neither provides a clear compliance pathway.
