The Federal Reserve has laid out a supervisory framework for stablecoin issuers that includes capital charges and a mandatory two-day redemption window, according to the proposal reported by finance.biggo.com. The framework represents the most detailed articulation to date of how the U.S. central bank expects issuers of payment stablecoins to manage reserve assets, liquidity and redemption obligations.

The two core pillars of the proposal address the two risks that regulators have repeatedly identified as systemic in stablecoin markets: insolvency of the reserve portfolio and the inability of holders to redeem tokens at par on demand.

Under the capital charge component, issuers would need to hold loss-absorbing buffers against their reserve holdings, so that a drawdown in the value of the underlying assets cannot leave the token undercollateralized. The design follows the same logic that banking supervisors apply to securities portfolios at deposit-taking institutions: reserves held in credit or duration-sensitive instruments carry risk weights, and equity capital must stand behind them.

The redemption rule is the more operationally demanding of the two requirements. A hard two-day window for processing redemptions would force issuers and their reserve managers to structure portfolios for liquidity, not just yield. Issuers holding commercial paper, term deposits or other instruments that cannot be monetized within 48 hours would face a structural choice: shorten asset durations, maintain standing credit lines, or hold larger buffers of near-cash instruments. Each option carries a direct cost to the interest income that has historically underpinned stablecoin issuer economics.

The operational consequences extend beyond the issuers themselves. Reserve custodians, prime brokers and the tokenization platforms that record ownership of reserve assets would all need to support settlement cycles compatible with a two-day redemption commitment. For issuers operating on multiple blockchains, the requirement also raises questions about how redemption queues are sequenced during periods of concentrated demand — precisely the scenario that collapsed several algorithmic and undercollateralized tokens in previous market stress episodes.

For the largest issuers — Tether and Circle, whose combined tokens account for the overwhelming majority of stablecoin circulating supply — the framework formalizes practices they already claim to follow in substance. Both companies publish reserve attestations and state that holders can redeem at par. The distinction is that a Federal Reserve supervisory standard converts voluntary disclosure into an enforceable obligation, with examination, reporting and remediation powers attached.

The capital charge question is thornier. Issuers currently distribute most reserve income to shareholders or, in Circle's model, to itself rather than to token holders. A binding capital requirement would lock a portion of that income into non-distributable buffers, directly compressing the net interest margin that constitutes the core business model of every major stablecoin issuer. The higher short-term rates have risen in recent years, the larger that compression becomes in absolute terms.

Smaller issuers face a proportionally heavier burden. Compliance infrastructure for reserve reporting, redemption processing and capital adequacy carries substantial fixed costs, and a Fed-supervised regime would likely accelerate consolidation toward a small number of large, well-capitalized issuers — an outcome regulators have themselves flagged as a financial stability concern.

The framework also interacts with pending legislation. Stablecoin bills advanced in both chambers of Congress would assign primary supervisory roles for large issuers to federal banking regulators, with the Federal Reserve and the Office of the Comptroller of the Currency as the leading candidates. A detailed Fed framework positions the central bank to act as the de facto standard-setter regardless of how the final legislative allocation of authority lands.

Market participants will now be watching for the formal publication of the proposal, the specifics of the risk weights attached to different reserve asset classes, and the comment period that follows. The ratio of required capital to reserves, and any phase-in schedule for the redemption requirement, will determine whether the framework functions as a compliance adjustment for the major issuers or as a structural reset of the stablecoin business model.
