The FDIC Board of Directors approved a notice of proposed rulemaking on May 22 that would establish Bank Secrecy Act and sanctions compliance standards for permitted payment stablecoin issuers under the agency’s supervision. The proposal, issued under authority granted by the Guiding and Establishing National Innovation for U.S. Stablecoins Act, marks the second major GENIUS Act implementation rule from the FDIC and arrives as the total stablecoin market capitalization stands at approximately 318 billion dollars, according to CoinGecko data.

What the Proposed Rule Requires

The rulemaking targets FDIC-supervised permitted payment stablecoin issuers that operate as subsidiaries of insured state nonmember banks and state savings associations. Under the proposed framework, these issuers would need to maintain anti-money laundering and countering the financing of terrorism programs aligned with standards set by FinCEN, the Treasury Department’s Financial Crimes Enforcement Network. The rule also mandates compliance with sanctions screening procedures administered by the Office of Foreign Assets Control, including watch-list monitoring and related reporting obligations.

The FDIC’s proposal would establish and align supervision and enforcement provisions for stablecoin issuer AML/CFT programs with existing FinCEN requirements. Customer due diligence, transaction monitoring, and suspicious activity reporting procedures would need to meet thresholds comparable to those applied to traditional financial institutions. The agency has opened a 60-day comment period following publication in the Federal Register, giving industry participants and the public an opportunity to respond before the rule is finalized.

Building on the GENIUS Act Framework

The May 22 proposal follows an earlier FDIC rulemaking approved on April 7 that established broader prudential standards for permitted payment stablecoin issuers. That initial rule addressed reserve asset requirements, redemption standards, capital requirements, and risk management frameworks. It also clarified that pass-through deposit insurance applies to deposits held as reserves backing payment stablecoins, and that tokenized deposits meeting the statutory definition of a deposit receive identical treatment under the Federal Deposit Insurance Act as conventional deposits.

Together, the two rulemakings create a layered regulatory architecture for stablecoin issuers operating within the federal banking system. The first rule sets prudential guardrails around reserves and capital, while the latest proposal layers financial crime compliance on top. The FDIC had also published a separate proposed rule in December 2025 addressing application procedures for bank subsidiaries seeking to issue payment stablecoins, establishing the procedural entry point for the broader framework.

Industry and Market Context

The regulatory push arrives at a time when stablecoins have become a central focus of federal policy. The GENIUS Act, signed into law earlier in 2026, created the legislative foundation for federal oversight of payment stablecoins, and multiple agencies including the FDIC and the Office of the Comptroller of the Currency have moved to implement its provisions. The stablecoin market remains dominated by Tether’s USDT at approximately 189.5 billion dollars in market capitalization and Circle’s USDC at roughly 76.5 billion dollars, according to CoinGecko. A House subcommittee hearing on May 22 separately examined broader modernization of the Bank Secrecy Act for digital assets and artificial intelligence, reflecting growing Congressional attention to updating financial crime frameworks for new technologies.

For issuers, the compliance burden could be significant in the near term. Building out AML/CFT infrastructure, hiring compliance personnel, and implementing sanctions screening systems requires substantial operational investment. Industry observers have noted, however, that clearer regulatory expectations could strengthen institutional confidence in stablecoin issuers and facilitate deeper banking relationships, potentially supporting broader adoption over time.

Risks and Uncertainties

The proposal’s scope is limited to FDIC-supervised entities, leaving open questions about how stablecoin issuers operating outside the traditional banking perimeter will be regulated. Critics have noted that the largest stablecoin issuers by market capitalization are not currently structured as subsidiaries of FDIC-insured banks, which could limit the rule’s immediate practical impact. The 60-day comment period may also surface industry pushback on specific compliance thresholds, particularly around transaction monitoring costs and reporting burdens for smaller issuers. Cross-border regulatory fragmentation remains another concern, as standardized U.S. sanctions compliance does not automatically resolve jurisdictional differences in how other countries supervise stablecoin activity. The final rule’s effectiveness will depend on whether the framework attracts stablecoin issuers into the regulated banking system or drives activity toward less supervised alternatives.
