"We will have a final rule out by November, so we are working with great speed here." — Jonathan Gould, Comptroller of the Currency, August 19, 2026
The Office of the Comptroller of the Currency is racing to finalize a 376-page federal rulebook for payment stablecoins by November 2026, four months before the GENIUS Act takes effect on January 18, 2027. The regulatory sprint involves three federal agencies — the OCC, FDIC, and FinCEN — issuing parallel rulemakings that together define who can issue stablecoins in the United States, what reserves they must hold, how they report to regulators, and whether they can pay yield to holders.
The stakes are measured in dollars: $302 billion in stablecoin supply as of early September 2026, $141 billion of which sits in U.S. Treasury bills held by a single issuer (Tether), and 23 of 40 new bank charter applications filed since January 2025 that include digital asset business plans. The rules being written now will determine whether the stablecoin market remains dominated by offshore crypto-native issuers or shifts toward FDIC-insured banks that are openly preparing to enter.
The compressed timeline — final rules in November, applications processed in early 2027 — leaves issuers, banks, and service providers a narrow window to build compliance infrastructure for a market that Standard Chartered projects could reach $2 trillion in supply within two years.
The GENIUS Act, signed by President Trump on July 18, 2025, established the legal category of "Permitted Payment Stablecoin Issuer" (PPSI) and assigned three federal agencies to write implementing rules. Each agency controls a different piece:
The law becomes effective on the earlier of January 18, 2027 (18 months after enactment) or 120 days after federal regulators issue final implementing rules. If the OCC delivers its final rule in November as promised, the 120-day clock would push the effective date to approximately March 2027 — later than the statutory default. The January date therefore holds.
Comptroller Gould has stated the OCC began drafting rules before the legislation was formally signed, and digital asset-related chartering activity has increased eightfold compared to the previous administration.
The OCC's Notice of Proposed Rulemaking, published February 25, 2026, runs 376 pages and covers nearly the entire lifecycle of a payment stablecoin. The comment period closed in May 2026. Key requirements:
Reserve composition: Issuers must hold reserves in permissible assets — primarily U.S. Treasury securities, insured deposits, and central bank reserves. Reserves must be bankruptcy-remote and segregated from the issuer's other assets.
Redemption: Stablecoins must be redeemable at par, on demand, in U.S. dollars. The proposal sets enforceable liquidity and redemption timing expectations.
Reporting: OCC Bulletin 2026-24, issued June 11, 2026, proposes two new reporting forms. Form PS-01 requires weekly confidential reporting of stablecoin activity and reserve composition. Form PS-02 requires quarterly reports of condition and income. The comment period for these forms closed August 11, 2026.
Wind-down: The proposal mandates orderly wind-down procedures for failed issuers, a provision absent from the voluntary frameworks that governed stablecoin issuance prior to the GENIUS Act.
Foreign issuers: The rules establish a supervisory framework for foreign payment stablecoin issuers operating in the U.S., requiring registration with the OCC.
The FDIC has issued two separate proposed rules in 2026:
Application procedures (published April 10, 2026): Establishes how FDIC-supervised insured depository institutions apply to issue payment stablecoins through subsidiaries.
BSA/Sanctions compliance (published May 22, 2026): Sets Bank Secrecy Act and sanctions compliance standards for FDIC-supervised PPSIs, aligning with FinCEN requirements.
Separately, FinCEN and OFAC published their own proposed rule on April 10, 2026, creating a new regulatory part that treats PPSIs as financial institutions under the BSA. The rule would require PPSIs to maintain both an AML/CFT program and an economic sanctions compliance program.
The Treasury Department added a further layer on August 18, 2026, proposing principles for determining when a state-level regulatory regime is "substantially similar" to the federal framework. The comment period for this Treasury proposal closes October 19, 2026.
The cumulative regulatory output in 2026 alone: at least six proposed rules across four agencies, all targeting the same market.
The stablecoin market stood at approximately $302 billion in total supply as of early September 2026, according to data aggregated by StablecoinBeat. The market peaked at $322 billion on April 16, 2026, and has contracted approximately 6% since, marking what Forbes described as the first contraction in four years.
Market structure remains concentrated:
| Issuer | Supply (Sept. 2026) | Market Share | |--------|-------------------|-------------| | Tether (USDT) | $183.3B | ~59% | | Circle (USDC) | $73.6B | ~24% | | All others | ~$45B | ~17% |
Tether and Circle command approximately 83% of total supply. The GENIUS Act's compliance requirements — including reserve audits, weekly OCC reporting, and AML programs — are calibrated to this reality. Both companies have the revenue base to absorb bank-grade compliance costs. Tether's Q1 2026 attestation showed a reserve base of $191.8 billion backing $183 billion in token liabilities.
The question is whether smaller or newer issuers can compete under the same regulatory burden.
According to Comptroller Gould, the OCC has received 40 applications for new bank charters over the 18 months since January 2025. Of those, 23 — approximately 57.5% — include digital asset business plans. Gould described integrating payment stablecoins into business plans as "ordinary course" activity in the regulatory pipeline.
Major banks have publicly signaled intent:
A consortium of regional banks — including Huntington, First Horizon, KeyCorp, M&T, and Old National — formed the Cari Network, targeting a customer-facing tokenized deposit network launch in Q4 2026 following a Q3 pilot.
JPMorgan, Citi, Bank of America, and Wells Fargo are separately building a tokenized deposit network through The Clearing House, targeting a 2027 launch for 24/7 interbank settlement.
Section 8 of the GENIUS Act prohibits payment stablecoin issuers from paying interest or yield to holders. The OCC's proposed rule extends this prohibition to affiliates and "related third parties," establishing a rebuttable presumption that certain affiliate arrangements violate the ban.
According to the Bank Policy Institute and American Bankers Association, the scope of this prohibition remains the most contested element in public comments. The law does not define "holder," leaving open whether the ban applies to the intermediary custodying the stablecoin or the end investor who owns it.
The prohibition has not eliminated yield. It has rerouted it through three channels:
DeFi lending: Aave, with $40 billion in TVL, offers 4–7% APY on stablecoin deposits. Compound offers 2–6%. These platforms sit outside the GENIUS Act's issuer-focused framework.
Platform rewards: Coinbase launched onchain USDC lending via Morpho in September 2025 with variable yields reaching 10.8%. Robinhood's "Robinhood Earn" offers an estimated 7% APY on USDG, its own stablecoin, with roughly half the advertised rate coming from subsidies rather than native return.
Tokenized Treasuries: BlackRock's BUIDL fund holds $2 billion in AUM at approximately 4.8% APY. Ondo's OUSG holds $692 million at 3.49–3.75% APY. Superstate's USTB reached $967 million before its acquisition by Invesco in Q2 2026.
The yield-bearing stablecoin treasury market now totals approximately $20 billion, according to BlockEden data. The CLARITY Act, a companion bill still in Congress, contains provisions that would explicitly allow crypto firms to offer stablecoin rewards while preserving the bank yield prohibition.
The GENIUS Act creates a two-tier system. State-chartered, nonbank stablecoin issuers with $10 billion or less in outstanding stablecoins may operate primarily under state oversight, provided the state regulatory regime is "substantially similar" to the federal framework. Above $10 billion, issuers must transition to federal regulation, obtain a waiver, or stop issuing.
The Treasury Department's August 18 proposal aims to define "substantially similar." State rules must not impede compliance with federal requirements but need not replicate detailed OCC processes.
This threshold creates a structural barrier. Of the current stablecoin market's approximately $302 billion supply, two issuers (Tether and Circle) account for $257 billion — both far above the state threshold. Any state-regulated issuer is by definition a small-market participant, capped at $10 billion unless it converts to federal oversight.
The practical effect: the GENIUS Act's most detailed and expensive requirements apply to exactly the issuers best positioned to absorb them, while smaller players face lighter regulation but also a hard growth ceiling.
Stablecoin issuers have become significant holders of short-term U.S. government debt. Tether's Q1 2026 attestation disclosed $117 billion in direct Treasury bill holdings and $24 billion in reverse repurchase agreements collateralized by Treasuries — $141 billion in total Treasury exposure. This makes Tether the 17th-largest holder of U.S. government debt globally, ahead of Germany and the UAE, according to Tether's public disclosures.
Circle holds approximately 32% of its reserves in U.S. Treasury bills. Combined, the top two stablecoin issuers hold an estimated $140–160 billion in T-bills.
Standard Chartered projected in February 2026 that the U.S. Treasury may need to boost T-bill issuance as the stablecoin market approaches $2 trillion in supply. At current reserve ratios, a $2 trillion stablecoin market would require roughly $1.2–1.6 trillion in T-bill holdings — a non-trivial increment to the roughly $6 trillion T-bill market.
The GENIUS Act's reserve requirements formalize what issuers already practice but add weekly reporting and regulatory oversight. The OCC's Form PS-01 would give regulators real-time visibility into the composition and adequacy of stablecoin reserves for the first time.
The regulatory machinery surrounding the GENIUS Act is moving faster than most crypto legislation has historically moved — and still may not move fast enough. The November target for the OCC's final rule leaves issuers, banks, and service providers approximately two months to build or retrofit compliance systems before the January 2027 effective date. For banks, the timeline is even more compressed: applications cannot be processed until the final rule is published, and approval timelines are unknown.
The six concurrent rulemakings represent an attempt to regulate a $302 billion market that was largely self-governed until July 2025. Whether this framework produces the intended effect — bringing stablecoins into the regulated banking system while maintaining the speed and programmability that made them useful — depends on implementation details that remain, as of September 2026, in proposed form. The comment periods are closed. The rules are being written. The market is waiting.
