The GENIUS Act is approaching implementation, introducing new reserve, redemption and licensing rules for payment stablecoins. Learn how the timetable could affect USDT access, issuers and crypto platforms in the US.
GENIUS Act Implementation Countdown Begins as USDT’s US Market Access Shifts
On 18 July 2026, the US GENIUS Act (GENIUS Act) reached the statutory deadline for federal regulators to complete the implementation rules. As of the 12–18 July 2026 window, seven agencies—the Office of the Comptroller of the Currency, Federal Deposit Insurance Corporation, Federal Reserve, National Credit Union Administration, Department of the Treasury, Financial Crimes Enforcement Network and Office of Foreign Assets Control—had yet to publish the final rule texts, leaving stablecoin issuers to continue their compliance preparations based on the proposed rules.
The Act was signed into law by the US President on 18 July 2025, establishing the country’s first federal regulatory framework specifically for payment stablecoins. It introduced uniform standards covering issuers’ reserve composition, redemption arrangements, disclosures and regulatory registration. The US market position ofUSDT, the world’s largest stablecoin by circulation, has consequently become a major focus for the market.

Dual Timetable for the Act’s Effective Date and Three-Year Transition Period
The GENIUS Act establishes two parallel timelines applying to different parties, which is the principal source of current differences in market interpretation.
Framework Effective Date: The Earlier of Two Dates
18 months after the Act was signed, namely 18 January 2027; or
120 days after the principal federal payment stablecoin regulators publish their final implementation rules.
The earlier date will apply. If the final rules are issued by the statutory deadline of 18 July 2026, the framework’s effective date will be brought forward from the backstop date of 18 January 2027. If rulemaking is delayed, the 18-month backstop provision will determine the effective date.
Three-Year Distribution Transition Period: 18 July 2028
Section 3(b) of the Act provides that, from the third anniversary of enactment—18 July 2028—digital asset service providers offering or selling payment stablecoins to any person in the United States will, in principle, be restricted to tokens issued by a “permitted payment stablecoin issuer” or by a foreign payment stablecoin issuer meeting specified conditions. The restriction covers trading platforms, brokers and custodians. Section 3(e) further specifies that the relevant provisions have extraterritorial effect where stablecoins are offered or sold to persons in the United States.

Comparison of Key Dates and Compliance Obligations
| Date | Event | Obligated Party | Legal Effect |
|---|---|---|---|
| 2025-07-18 | Act signed into law | All market participants | Three-year transition period begins |
| 2025-12 to 2026-06 (window) | Seven agencies publish proposed rules | Issuers and service providers | Covers capital, reserves, liquidity, redemption and anti-money laundering |
| 2026-07-18 | Statutory deadline for final rules | Federal regulators | The Act provides no automatic extension mechanism |
| 2027-01-18 | Framework backstop effective date | Payment stablecoin issuers | The earlier of this date or 120 days after the final rules |
| 2028-07-18 | Distribution restrictions commence | Exchanges, brokers and custodians | Non-compliant stablecoins may not be offered or sold in the US |
Core Compliance Thresholds Set Out in the Proposed Rules
The proposed rules published between December 2025 and June 2026 have outlined the basic structure of the regulatory framework, principally covering the following requirements:
A minimum capital floor of US$5 million;
Issuers must maintain a same-day liquidity buffer;
Redemption requests must be completed within two business days;
Issuers will be brought within the scope of the Bank Secrecy Act;
Reserve assets will be limited to US dollar cash, Federal Reserve deposits, insured bank deposits, US Treasury securities with a remaining maturity of no more than 93 days, overnight repurchase agreements backed by Treasury securities and eligible money market funds;
Reserves must fully support stablecoins in circulation at a ratio of no less than 1:1, with reserve composition disclosed monthly;
Issuers may not pay reserve income to token holders in any form.
Certain obligations are subject to separate timetables. Once the Financial Crimes Enforcement Network and Office of Foreign Assets Control publish their final anti-money laundering rules, issuers will receive a 12-month period to establish the required compliance procedures.

Diverging Approaches Taken by Tether and Circle
As of 12 July 2026, USDT had a market capitalisation of approximately US$184.16 billion, whileUSDChad a market capitalisation of approximately US$73.37 billion and was quoted at US$0.9998. Together, they account for the principal share of US dollar-pegged stablecoin supply and are therefore primary targets of the new framework.

Differences in Reserve Composition
Tether’s public disclosures show that USDT reserves continue to include asset classes such as precious metals, loan exposures and Bitcoin holdings. These assets may support income generation and portfolio diversification, but they differ structurally from the list of eligible reserve assets set out in the proposed rules. Tether has stated its intention to comply with the new requirements, but has not yet published a comprehensive plan to restructure USDT’s reserves or operating model around the US framework.
Additional Conditions for Foreign Issuers
To retain listing eligibility on US centralised trading platforms, non-US stablecoin issuers must satisfy requirements relating to reserve custody, regulatory registration, compliance with lawful freezing and seizure orders, and supervision by a home-country regulator considered comparable to the US regulatory system. Tether has launched a separate stablecoin, USAT, for the US market through Anchorage Digital, although its scale remains significantly smaller than USDT and it has not replaced USDT’s liquidity role in the global cryptocurrency market. Circle, by contrast, has taken clearer steps to align itself with the US regulatory framework.
Market Restructuring May Precede the Statutory Deadline
Justin Levin, a lawyer advising clients on stablecoin compliance, noted that once the Act takes effect, foreign issuers will first be required to comply with lawful freezing and seizure orders, while having approximately two years to prepare for the additional requirements that will determine whether their tokens may continue to be listed on US centralised trading platforms.
“A compliant, bank-issued digital dollar.”
Market interpretations of the timetable differ and may lead to segmentation among US trading platforms:
Small and medium-sized platforms with limited legal resources may delist higher-risk stablecoins before the mandatory regulatory deadline;
Larger platforms are more likely to maintain listings of stablecoins issued outside the US while awaiting clearer regulatory guidance or increased enforcement pressure;
Institutional liquidity migration may occur before the formal deadline of 18 July 2028.
USDT is deeply embedded in global cryptocurrency trading, offshore platform liquidity and digital-asset dollar settlement channels. Restrictions in the US market would not remove it from global circulation, but could weaken its role in regulated US trading and institutional settlement. Reserve composition, regulatory access, banking relationships and the ability to respond to legal orders are replacing circulation and trading volume as the core variables determining which US dollar stablecoins can maintain large-scale distribution in the US market.
GENIUS Act and USDT Compliance Questions
On what date does the GENIUS Act take effect?
The earlier of two dates will apply: 18 January 2027, which is 18 months after signing, or 120 days after the principal federal payment stablecoin regulators publish their final implementation rules. As of 18 July 2026, the final rules had not been published, so the precise effective date still depends on when the rules are issued.
Who is subject to the 18 July 2028 deadline?
The deadline applies to digital asset service providers, including exchanges, brokers, custodians and other parties involved in distribution. From that date, payment stablecoins offered or sold by them in the United States must be issued by a permitted payment stablecoin issuer or by a foreign issuer meeting specified conditions.
Which assets may be used as stablecoin reserves under the Act?
Eligible assets include US dollar cash, Federal Reserve deposits, insured bank deposits, US Treasury securities with a remaining maturity of no more than 93 days, overnight repurchase agreements backed by US Treasury securities and eligible money market funds. Reserves must cover stablecoins in circulation at a ratio of no less than 1:1, with their composition disclosed monthly.
May issuers distribute reserve income to token holders?
No. The Act prohibits issuers from paying reserve income, typically interest earned on Treasury securities, to holders as a feature of the token. Alternative arrangements linked to token balances, including rebates or points-based schemes, are also within the scope of the prohibition.
What is the relationship between USAT and USDT?
USAT is a separate stablecoin issued by Tether through Anchorage Digital for the US market, and it is distinct from USDT. At present, USAT remains far smaller than USDT and has not assumed USDT’s liquidity role in the global market.
What happens if regulators fail to publish the final rules on time?
The Act provides no automatic extension mechanism. A delay in publishing the rules would mean that the framework’s effective date falls back to the backstop date of 18 January 2027, while issuers would have to continue preparing their compliance programmes on the basis of the proposed rules until then.
