US GENIUS Act proposed rules
The GENIUS Act, enacted on July 18, 2025, established the first comprehensive federal framework for payment stablecoins in the United States. By mid-2026, the Treasury Department, the Office of the Comptroller of the Currency (OCC), and the Federal Deposit Insurance Corporation (FDIC) released proposed rules to implement the law’s requirements. These regulations define how issuers must manage reserve assets, maintain redemption capabilities, and operate within the US financial system.
The Treasury’s proposed rule focuses on the composition and custody of reserve assets. Under the GENIUS Act, permitted payment stablecoin issuers (PPSIs) must back outstanding tokens with high-quality, liquid assets. The proposed rules specify that reserves may consist of US dollars, federal reserve notes, and funds held at regulated institutions. This approach aims to prevent issuers from investing in riskier assets that could jeopardize the stablecoin’s peg during market stress.
The OCC and FDIC proposed rules address the operational and supervisory aspects of stablecoin issuance. The OCC’s proposal outlines requirements for OCC-regulated national banks and federal savings associations that wish to issue stablecoins. It details where and how these institutions may hold reserve assets, ensuring they meet strict safety and soundness standards. The FDIC’s proposal, released on April 7, 2026, requires PPSIs to redeem stablecoins within two business days. This redemption timeframe is designed to protect consumers and maintain liquidity in the event of a sudden surge in redemption requests.
These proposed rules represent a significant step toward integrating stablecoins into the regulated financial system. By setting clear standards for reserves, redemption, and institutional oversight, the agencies aim to foster innovation while mitigating risks to consumers and financial stability. The public comment period for these proposals remains open, allowing stakeholders to provide feedback before final rules are adopted.
Reserve asset composition
The GENIUS Act, passed by Congress in July 2025, establishes a strict framework for payment stablecoins. It mandates that issuers maintain reserves backing outstanding tokens on at least a one-to-one basis. This requirement ensures that every unit of stablecoin in circulation is fully supported by high-quality liquid assets, eliminating the fractional reserve practices seen in earlier models.
Under the proposed rules from the OCC and NCUA, reserve assets are limited to specific categories. Permitted holdings include US dollars, Federal Reserve notes, and funds held at insured depository institutions or regulated money market funds. The goal is to minimize credit risk and ensure immediate redemption capability for users.
This approach contrasts sharply with previous industry standards where stablecoins often held corporate commercial paper or longer-dated government securities. By restricting the asset pool to cash and cash equivalents, the new regulations prioritize safety and liquidity over yield generation. Issuers must also disclose their reserve composition clearly and undergo regular attestation or audit to verify compliance.
The comment period for these proposed rules closes on April 13, 2026. Issuers are currently reviewing the specific operational requirements for where and how these assets must be held. The final rules will likely refine the definition of "regulated" financial institutions and the acceptable custody arrangements for these reserves.
MiCA implementation status
The European Union’s Markets in Crypto-Assets (MiCA) regulation has moved from legislative framework to operational reality for stablecoin issuers. As of 2026, the regulation’s provisions regarding asset-referenced tokens (ARTs) and e-money tokens (EMTs) are fully enforceable across all member states. This marks the end of the transitional period that began when the regulation first came into force in late 2024. Issuers must now hold valid licenses from national competent authorities to operate within the EU single market.
The European Securities and Markets Authority (ESMA) continues to coordinate the application of these rules, ensuring consistent oversight across jurisdictions. National authorities, such as Germany’s BaFin and France’s ACPR, are actively supervising licensed entities. The regulatory focus remains on reserve management, transparency, and consumer protection. Issuers must maintain reserves that are fully backed, liquid, and segregated from their operational funds. This structure is designed to prevent the kind of solvency crises that have affected stablecoins in unregulated markets.
While the core EU-wide framework is set, some national implementations are still finalizing technical details. These include specific reporting formats and interaction protocols with national payment systems. However, the fundamental licensing requirements are clear: only supervised entities can issue or process stablecoins. This creates a level playing field for compliant businesses while restricting access for unauthorized operators. The result is a more structured stablecoin market in Europe, prioritizing stability and legal certainty over rapid, unchecked expansion.
Cross-border payment implications
The convergence of the European Union’s Markets in Crypto-Assets (MiCA) regulation and the United States’ GENIUS Act creates a dual regulatory framework that fundamentally alters cross-border stablecoin payments. Passed by the U.S. Congress in July 2025, the GENIUS Act establishes a federal framework requiring payment stablecoin issuers to maintain one-to-one reserves in liquid, low-risk assets. This aligns with MiCA’s strict reserve requirements, reducing the regulatory arbitrage that previously allowed issuers to operate in jurisdictions with lax oversight.
For cross-border transactions, this harmonization reduces compliance friction. Businesses and consumers can now rely on a clearer legal standard for stablecoin issuance across major Western economies. The Federal Reserve notes that these regulatory shifts are accelerating the adoption of stablecoins as a global payment rail, particularly for remittances and B2B settlements where efficiency gains are immediate. By standardizing reserve backing and operational transparency, regulators are attempting to mitigate the systemic risks associated with unbacked digital assets.
However, the implications extend beyond simple transaction speed. The Federal Reserve has highlighted that the widespread use of regulated stablecoins could impact monetary policy transmission. As stablecoins increasingly serve as a medium of exchange rather than just a speculative asset, central banks must monitor how capital flows and liquidity are affected by these private digital currencies. The interplay between U.S. and EU rules will likely dictate the next phase of global digital finance, balancing innovation with financial stability.
The Fed’s March 2026 analysis notes that payment stablecoins are increasingly used for cross-border payments, with regulatory clarity driving adoption in remittances and treasury operations.
What issuers must do next
Regulated entities navigating the stablecoin regulation 2026 landscape face immediate, time-sensitive obligations under both MiCA and the US GENIUS Act. The regulatory window for shaping final rules is closing, making timely participation in comment periods the highest-impact action for current stakeholders.
In the United States, the National Credit Union Administration (NCUA) has proposed a rule for permitted payment stablecoin issuer applications. The comment period for this proposed rule closes on April 13, 2026. Issuers should review the full proposal and submit feedback before the deadline to influence the final compliance framework.
Simultaneously, the GENIUS Act mandates that issuers maintain reserves backing outstanding payment stablecoins on at least a one-to-one basis. These reserves must consist of specified assets, including US dollars and federal reserve notes. Issuers must audit their current reserve structures to ensure they meet these strict liquidity and asset-quality standards before the compliance deadlines take effect.
Stablecoins are increasingly functioning as a global payment rail, with cross-border transfers and B2B settlements driving the strongest momentum in 2026. However, this operational efficiency must be balanced against the new regulatory rigor. Issuers who align their reserve policies and application processes with these upcoming requirements will be better positioned to operate within the compliant stablecoin regulation 2026 framework.
