If you hold a dollar-pegged stablecoin, the money backing it probably sits in a bank account somewhere. But if that bank fails, nobody has been able to tell you with certainty whether federal deposit insurance covers your share of those reserves. On April 7, 2026, the Federal Deposit Insurance Corporation took its first concrete step toward answering that question, approving a Notice of Proposed Rulemaking that would set binding standards for how banks handle stablecoin reserves and when those reserves qualify for pass-through deposit insurance. Final rules are expected by late 2026.
The proposal arrives as the stablecoin market has grown past $230 billion in total capitalization, with tokens like USDC and USDT functioning as core infrastructure for crypto trading, cross-border payments, and decentralized finance. Until now, the reserves backing those tokens have existed in a regulatory gray zone: held at banks, but without clear federal rules governing custody, recordkeeping, or insurance eligibility.
What the FDIC proposal actually does
The April 7 rulemaking covers three distinct areas. First, it establishes prudential standards for payment stablecoin issuers supervised by the FDIC. Second, it clarifies when reserve deposits backing those tokens qualify for deposit insurance. Third, and perhaps most consequentially, it imposes enhanced governance, disclosure, and recordkeeping obligations on any insured bank that holds or custodies reserve assets on behalf of an issuer, even if the bank itself does not issue tokens.
That third category extends the agency’s reach well beyond issuers. A regional bank that wins a contract to hold reserves for a stablecoin company would face new requirements designed to make insurance determinations cleaner if the bank were to fail. The FDIC would need to trace coverage back to individual token holders, which means banks must demonstrate controls over wallet mapping, omnibus account reconciliation, and reserve identification.
The proposal is anchored to the GENIUS Act, bipartisan legislation that passed the Senate Banking Committee in early 2026 and, as of May 2026, remains pending before the full Senate. The bill would establish a federal licensing and oversight framework for payment stablecoins. The FDIC’s rulemaking translates the act’s broad mandates into specific supervisory expectations, making it the first agency-level action to convert congressional intent into enforceable deposit insurance and capital standards for stablecoin-related banking activity.
How regulators got here
This rulemaking caps a dramatic reversal in federal banking agencies’ posture toward crypto over roughly 18 months.
In 2022 and 2023, the FDIC, Federal Reserve Board, and Office of the Comptroller of the Currency issued joint statements warning banks about crypto-asset risks. The FDIC went further with FIL-16-2022, requiring banks to notify the agency before engaging in any crypto-related activity and effectively giving examiners veto power over new business lines. The chilling effect was well documented: in March 2025, the FDIC released 175 internal supervisory documents showing how examiners had delayed or discouraged banks seeking to offer crypto services, even when agency leadership signaled openness.
The pivot began in early 2025. The three agencies jointly withdrew the 2023 interagency statements. The FDIC then issued FIL-7-2025, which eliminated the prior notification and approval requirement, allowing banks to pursue permissible crypto activities through normal supervisory channels. The Federal Reserve Board separately withdrew its own restrictive guidance on crypto-asset and dollar token activities.
A joint interagency release on risk-management considerations for crypto-asset safekeeping reinforced the shift. The FDIC, Fed, and OCC stated explicitly that the guidance “does not create any new supervisory expectations” but instead clarifies existing risk-management principles. That distinction matters: the safekeeping statement is informational, while the GENIUS Act rulemaking will produce binding rules.
The trajectory is unmistakable. Agencies warned banks away from crypto in 2023, reversed course in 2025, and are now proposing to bring stablecoin custody inside the regulated banking system with formal standards.
What remains unresolved
The NPRM establishes a framework, but several critical details are still open.
The specific reserve-asset tests, capital and liquidity thresholds for issuers, and the mechanics of pass-through insurance determinations have not been finalized. Banks do not yet know whether all fiat-denominated reserves in segregated accounts will qualify for coverage automatically or whether additional operational controls will be required on a case-by-case basis. The comment period has not closed, and the agency has not indicated how long it will run. Until a final rule is issued, proposed prudential standards could tighten or loosen based on feedback from industry participants, consumer advocates, and fellow regulators.
That uncertainty complicates product design decisions right now. Whether to structure a new stablecoin as a bank liability, a trust interest, or an off-balance-sheet instrument could carry very different consequences under the final rule. Issuers and their banking partners are, for the moment, building on shifting ground.
There is also a gap between policy and practice. The 175 supervisory documents released in 2025 revealed that field-level examiners did not always match leadership’s stated openness to crypto. Whether the new rulemaking will override that pattern or simply layer formal standards on top of informal friction is a live concern, particularly for community and regional banks that depend heavily on examiner relationships.
State-level coordination adds another layer of complexity. Several states already license stablecoin issuers or digital asset trust companies. The GENIUS Act framework focuses on FDIC-supervised institutions, but it could indirectly pressure nonbank issuers if counterparties start favoring tokens backed by reserves at insured banks under a clear federal regime. Whether the FDIC will coordinate with state regulators on examination protocols and information sharing has not been addressed publicly.
What this means for the two biggest stablecoin issuers
The proposal’s practical impact depends heavily on how it interacts with the market’s dominant players. Circle, the issuer of USDC, already holds the bulk of its reserves at regulated U.S. financial institutions and has publicly sought a federal banking charter. A clear pass-through insurance framework could strengthen USDC’s competitive position by giving institutional buyers additional confidence in the token’s backing.
Tether, the issuer of USDT and the largest stablecoin by market capitalization, operates outside the U.S. banking system and has faced persistent questions about reserve transparency. The FDIC’s rulemaking does not directly regulate offshore issuers, but it could reshape the competitive landscape: if U.S.-regulated stablecoins offer verifiable deposit insurance on reserves, institutional demand may shift toward tokens that can make that claim. How Tether responds, whether by seeking closer ties to the U.S. banking system or doubling down on its offshore model, will be one of the most consequential market dynamics to watch as the rule takes shape.
Where the rulemaking goes from here
The FDIC has laid out a clear direction: federal regulators expect systemically important payment tokens to operate inside, not outside, the traditional safety net. That is a meaningful shift from even two years ago, when the same agency was quietly discouraging banks from touching crypto at all.
But direction is not the same as destination. How wide the supervised path becomes depends on the final rule’s contours, the quality of industry engagement during the comment period, and whether day-to-day bank supervision catches up with the policy changes documented in recent months. Banks, issuers, and the millions of people who hold stablecoins are all waiting on the same thing: the specific language that will determine whether “insured” on a stablecoin reserve account means what everyone assumes it means. That answer is expected by late 2026. Until then, the rules of the game are changing, but the new boundaries have not been drawn.
