The Guiding and Establishing National Innovation for United States Stablecoins Act (GENIUS Act) takes effect January 18, 2027, with significant restrictions on foreign stablecoin issuers. From July 18, 2028, digital asset service providers including exchanges, custodians, and transfer services may not offer or sell any payment stablecoin to U.S. persons unless it comes from a permitted issuer, and must verify a foreign issuer's compliance before offering its coins. The proposal carves out self-custody, direct peer-to-peer transfers, and same-owner transactions, while offering a safe harbor for inadvertent issuance conditioned on policies against U.S.-targeted marketing. Treasury poses dozens of questions, including how far providers must go to ensure offers don't reach U.S. persons, making the impact of this prohibition clearer than previously anticipated. Tether Limited, whose USDT is the largest stablecoin globally with most adoption outside the U.S., faces particular challenges as its reserves include gold and bitcoin, which are disallowed by GENIUS. After July 2028, a U.S. provider cannot offer a swap from USAT into USDT to a U.S. person, as that swap is an offer of USDT. The NPRM confirms what the statute implied: GENIUS is on track to close the U.S. market to foreign stablecoins that don't meet its requirements, and the closure arrives sooner than the 2028 date suggests.
Tether Limited, the issuer of USDT, faces the most consequential unresolved question in GENIUS Act implementation with approximately $140 billion in circulation as of August 2026. As reported by CoinDesk, Tether requires a Treasury reciprocity determination to continue serving United States businesses under the foreign issuer pathway, and as of August 2026, that determination has not been issued for any jurisdiction, including the British Virgin Islands where Tether is incorporated. The market has responded to this uncertainty, with USDT's share of United States exchange trading volume declining from 72% in January 2026 to approximately 64% in August, while USDC's share has grown from 18% to 26% over the same period. Tether has responded with plans to register USDT under the foreign issuer pathway and launched USAT, a new United States focused stablecoin designed for GENIUS Act compliance. However, after July 2028, a U.S. person holding USAT who wants to pay a counterparty abroad in USDT will have no legal onshore venue for the trade, as swapping USAT into USDT is an offer of USDT for sale. The squeeze starts in January 2027: offering the swap remains legal, but marketing it to U.S. persons does not.
The GENIUS Act requires every stablecoin issuer serving United States users to be licensed, maintain 100% reserves in Treasury bills or insured deposits, report weekly to regulators, and publish monthly disclosures. According to CoinDesk, issuers above $50 billion in market capitalization must submit to annual audits, with all issuers facing disclosure requirements that exceed current voluntary standards. Circle's USDC is closest to full compliance, holding reserves primarily in Treasury bills and regulated as a money transmitter in multiple states, while Ripple's RLUSD, which crossed $2 billion in market capitalization during August 2026, is designed for GENIUS Act compliance with reserves held in United States denominated assets. The law takes effect on either January 18, 2027 (18 months after signing) or 120 days after final rules are issued, whichever comes first. The ABA and Bank Policy Institute jointly asked the OCC to delay finalizing its new weekly and quarterly reporting forms for permitted stablecoin issuers until the substantive GENIUS Act rules are final, to define the reporting terms consistently with Call Report instructions, and to drop the line item collecting how much of an issuer's reserves are held in tokenized form. The rest of the letter is considerably less accommodating, wanting issuers filing the full forms on top of whatever they already file, and objects to the FDIC's lighter weekly form for issuers under $1 billion as an invitation to regulatory arbitrage.
FASB issued a proposed Accounting Standards Update on cash equivalents with two components that directly connect to GENIUS Act compliance. All entities presenting cash equivalents would disclose their significant components and amounts, whether or not any are digital assets, while new illustrative examples clarify how the existing cash-equivalents definition applies to digital assets such as stablecoins. Under the examples, a stablecoin qualifies only if the holder has a direct, on-demand contractual redemption right against the issuer at a fixed amount, redemption carries no significant fees or restrictions, and the issuer maintains segregated reserves of cash and Treasury bills with original maturities of three months or less on at least a 1:1 basis; secondary-market saleability alone is not sufficient. The proposal requires all qualifying holdings to move out of the intangibles footnote and into cash, with comments due November 19, 2026. This change sets a precedent for requiring banks to report on how much of their deposit base is tokenized, which is a question no bank wants on a Call Report because it triggers supervisory questions about whether an instantly redeemable, always-on liability deserves its own outflow assumption under LCR. FASB didn't change the definition of cash equivalents because it didn't need to. The GENIUS Act codified redemption rights and reserve quality, so certain compliant coins already fit. The board is simply saying so with examples, and requiring everyone to disclose what sits inside the cash-equivalents line. When FASB took this project up last November, I wrote that reclassification would broadly unblock corporates to hold and use stablecoins like cash deposits and money market instruments, and in March, when the SEC gave payment stablecoins a 2% net capital haircut, that stablecoins were marching up the balance sheet toward being formally treated as money. This proposal is the final step in that march: qualifying holdings move out of the intangibles footnote and into cash.
The delay has created a bottleneck for institutional products, with the Clearing House tokenized deposit network targeting a launch in the first half of 2027, assuming GENIUS Act rules are final. As reported by CoinDesk, FASB's August 18 proposal to treat qualifying stablecoins as cash equivalents on corporate balance sheets is directly connected to the GENIUS Act timeline, with the accounting treatment requiring stablecoins to carry on-demand redemption rights and segregated one-to-one reserves. The OUSD revenue sharing stablecoin consortium, including Visa, Mastercard, Stripe, and BlackRock among its 140+ partners, has positioned itself to capitalize on this convergence, with a stablecoin that qualifies as a cash equivalent under FASB and meets GENIUS Act reserve requirements becoming functionally equivalent to a Treasury bill on corporate balance sheets. When this change lands, corporate stablecoin demand will arrive through banks' commercial customers, and banks that can hold, convert, and move stablecoins from the deposit account will be the ones who keep the relationship. Two qualifications matter for this transformation: first, the examples require a direct redemption right against the issuer, which burdens holders who would need redemption accounts with every issuer they touch, and undercuts intermediaries who make multi-stablecoin convenience possible; issuers should be drafting flow-through provisions that extend the legal redemption right through intermediaries to end holders. Second, the successful examples look through to reserves with original maturities of three months or less, while GENIUS permits investments with remaining maturity under 93 days, which could disqualify even USDC, which routinely holds near-maturity paper with longer original maturities.
