# Fed Gives Stablecoin Issuers 24 Hours to Report a Reserve Shortfall Under Draft GENIUS Act Rules

An issuer that cannot restore full backing would have to liquidate reserves and start redemptions, a sequence that compresses a shortfall into about two days.

On 24 September, the Federal Reserve Board of Governors [opened comment on two draft rules](https://www.bnnbloomberg.ca/markets/crypto/2026/09/24/us-federal-reserve-proposes-new-stablecoin-rules/) for the payment stablecoin issuers it supervises under the Guiding and Establishing National Innovation for US Stablecoins Act (GENIUS Act), which became law in July 2025. The first draft requires tokens to be matched at all times by allowed reserve assets, limited to highly liquid instruments such as short-dated Treasury bills.

The enforcement mechanism is a clock. An issuer whose reserves fall below the value of its outstanding tokens gets [24 hours to notify the Fed and submit a plan to restore full backing](https://cryptoslate.com/fed-proposed-stablecoin-rule-could-trigger-a-48-hour-liquidation-run/). If the plan does not satisfy supervisors, the issuer must begin selling reserve assets and processing redemptions. CryptoSlate's reading is that the two steps together create roughly a 48-hour window in which a supervised issuer publicly liquidates into a market that already knows it is short. The proposals carry a 60-day comment period and are not final.

The scope matters as much as the clock. Circle's USDC, with $75.39 billion outstanding, sits inside the American supervisory perimeter. Tether's USDT, at $183.75 billion of the $313.03 billion stablecoin float, is issued offshore, and Washington's practical interest in it runs the other way. [Tether's Treasury holdings of roughly $114 billion](https://cryptoslate.com/washington-has-114-billion-reasons-to-want-tether-around/) make it a buyer of American government debt and a distributor of dollar exposure abroad. The same government that fined Tether for misrepresenting its reserves now has a fiscal reason to want those tokens circulating. A rulebook that binds the supervised issuer tightly while the largest issuer stays outside it changes the competitive picture before it changes run risk.

## What this means

The mechanism is disclosure timing. A mandated notification followed by a supervised liquidation converts a private reserve gap into a public one within days, and holders who read the signal redeem first, which is the behavior bank resolution law has spent a century trying to suppress. Circle and other Fed-supervised issuers carry that cost directly, while offshore issuers face none of it and can advertise the absence of a forced-sale trigger. The precedent is USDC's March 2023 depeg after Silicon Valley Bank failed, when the discount closed only once the deposit backstop became explicit, not when the reserve composition was published. The likelier outcome in the 60-day comment window is that issuers and their banks press for a confidential cure period before any liquidation obligation bites, and the Fed softens the sequencing rather than the full-reserve requirement itself. If the final rule keeps the hard clock instead, expect supervised issuers to hold shorter-dated reserves and larger capital buffers than the statute requires, and expect USDT's offshore share of the float to keep growing.

## What to watch

- Whether comment letters from Circle, banks and payment firms target the liquidation trigger rather than the reserve definition, which would show where the industry thinks the real cost sits.
- Whether the supervised share of the $313.03 billion stablecoin float grows or shrinks over the comment period, the cleanest measure of whether regulation is pushing issuance offshore.
- Any Fed or Treasury statement on liquidity support for a supervised issuer in distress, since the rule assumes an orderly sale into a market that may not bid.
