Editorial policyThe GENIUS Act’s one-year rulemaking deadline was 18 July 2026. No coordinated final rules hit the Federal Register. That miss does not repeal the statute and does not make USDT or USDC unlawful the next day. Section 20 (or the equivalent effective-date clause in enacted text) still points at the earlier of 18 January 2027 or 120 days after primary-regulator finals. As of late August 2026 the January 2027 backstop is the planning date. Educational only; not legal advice.
US agencies did not publish final GENIUS Act payment-stablecoin rules by the statutory 18 July 2026 date. NPRMs remain. The Act’s default effective date is 18 January 2027 unless finals start the 120-day clock first — a path that needed roughly mid-September 2026.
Skip this recap if you wanted the conceptual map of licensing and reserves — that is the evergreen GENIUS explainer. Skip it if you thought 18 July was ‘stablecoins banned.’ Our June countdown is now historical.
On 18 July 2025 the GENIUS Act was signed (Public Law 119-27 in contemporaneous citations). One year later, 18 July 2026, primary federal payment-stablecoin regulators were supposed to have promulgated implementing rules. They did not. Coverage in July and August 2026 — including Crowdfund Insider’s 19 July round-up at www.crowdfundinsider.com/2026/07/292568-the-genius-act-deadline-passes-without-final-stablecoin-rules-from-us-regulators/ — found notices of proposed rulemaking, not finals, with some comment windows still open after the deadline.
The miss has no statutory ‘penalty’ that delays the Act forever. It removes slack. The effective date is the earlier of 18 months after enactment (18 January 2027) or 120 days after primary-regulator final rules. To beat January via the 120-day trigger, finals needed to land around mid-to-late September 2026. Late-August comment-period posture made that optimistic. Treat 18 January 2027 as the date issuers and US-facing venues actually plan against unless the Federal Register says otherwise.
Circle-style transparent reserves remain the path of least resistance for US-facing platforms. Tether’s offshore structure is still the harder federal fit. That sentence was true in our June countdown and is still true; only the calendar changed. DAI, USDS, crvUSD and similar crypto-backed dollars remain outside many ‘payment stablecoin’ readings pending CLARITY and agency definitions.
Do not reweight a Curve pool because a deadline was missed. Do update any internal memo that still says ‘finals due 18 July 2026’ as if that date were in the future. The evergreen explainer at /regulation/genius-act-explained/ now matches this recap.

Historical June 2026 countdown: agencies were due to publish final GENIUS Act stablecoin rules by 18 July 2026. That deadline was missed — read the August recap for the January 2027 effective-date backstop.
The GENIUS Act — the first major US federal stablecoin legislation — has passed the Senate and is advancing to the House of Representatives. The bill establishes a licensing framework for stablecoin issuers, reserve requirements, and federal oversight. Here is what it means for USDC, USDT, and DeFi protocols that rely on stablecoins.
Leader Thune filed cloture on the motion to proceed to H.R. 3633. The first 60-vote test is 2:15 p.m. ET on 15 September — it is not final passage. CFTC Chair Selig has said the agency can still write rules if the bill stalls.
