In a development that could shift the way regulated stablecoins are perceived in the United States, Deloitte has issued the first-ever reserve attestation for Tether’s newly launched U.S. dollar‑pegged stablecoin, USAT.
The attestation covers the backing of the token as of January 31, 2026—marking a notable moment in Tether’s ongoing effort to win institutional confidence and align more closely with U.S. regulatory expectations.
Key Takeaways
- Deloitte issued the first-ever reserve attestation for Tether’s USAT stablecoin, confirming $17.6 million in reserves against 17.5 million tokens.
- USAT’s reserves consist of $3.65 million in cash and $13.95 million in short-term U.S. Treasury-backed reverse repurchase agreements.
- The attestation confirms the reserves at a snapshot in time but does not assess daily management, internal controls, or broader regulatory compliance.
- USAT is designed to comply with the U.S. GENIUS Act and is issued through Anchorage Digital Bank to appeal to institutional and regulatory-focused investors.
- This attestation represents Tether’s first Big Four verification for a U.S.-regulated stablecoin, signaling a push toward transparency and credibility in the domestic market.
A Snapshot of USAT’s Reserve Validation
The report, prepared by Deloitte under criteria set by the American Institute of Certified Public Accountants (AICPA) for asset‑backed, fiat‑pegged tokens, confirmed that USAT had $17.6 million in reserves backing 17.5 million tokens in circulation at the end of January. That leaves a slight excess of roughly $103,000, indicating the backing exceeded supply.
USAT’s reserve composition is straightforward: about $3.65 million held in U.S. dollar cash and roughly $13.95 million in very short‑term reverse repurchase agreements collateralized by U.S. Treasury securities.
Those repurchase positions matured in late January and early February and were managed through a registered U.S. broker‑dealer. The cash holdings were kept in bank and brokerage accounts that generally provide federal insurance protections, though some portions were above standard coverage limits.
What the Attestation Does and Doesn’t Tell Us
It’s crucial to understand that this engagement was an attestation rather than a full audit. Deloitte’s role was to assess whether the reserve report was fairly presented in accordance with the AICPA’s 2025 stablecoin criteria at a specific point in time.
The firm did not examine how reserves are managed day‑to‑day, evaluate internal controls, or judge compliance with all federal, state, or local regulations.
That distinction matters because a full audit would involve deeper scrutiny of financial systems, governance, and ongoing reserve practices—areas that regulators and institutional investors often demand for higher assurance.
Tether CEO Paolo Ardoino has publicly stated that securing a broad, independent audit from a Big Four firm is a top objective, even as major accounting firms have historically avoided full audits of Tether’s main stablecoin, USDT.
A Strategic Push Into Regulated Dollar Tokens
USAT represents Tether’s calibrated re‑entry into the U.S. stablecoin market under a formal regulatory framework known as the GENIUS Act, which went into effect in July 2025. This law requires stablecoin issuers operating in the U.S. to hold high‑quality reserves and operate under federal oversight — a significant departure from Tether’s traditional practice with USDT, which has faced long‑standing scrutiny for its audit history and international orientation.
Issued through Anchorage Digital Bank, USAT is structured to maintain a strict 1:1 peg with the U.S. dollar on the Ethereum blockchain. Anchorage, chartered in 2021 as the first federally regulated digital asset bank in the U.S., partnered with Tether to design a stablecoin that could satisfy Federal Reserve and regulatory expectations directly.
In messaging surrounding the report, Tether has framed USAT as a blend of its global stablecoin experience with Anchorage’s U.S. regulatory standing, positioning the token as appealing to institutional and compliance‑focused market participants.
Market Context and Competitive Backdrop
USAT’s $17.6 million reserve base and initial market cap of roughly $20 million may seem modest when compared to the broader stablecoin landscape, where the total market cap approaches $300 billion and dominant tokens like USDT and Circle’s USDC alone account for the vast majority of supply.
However, the significance of this announcement lies less in scale today and more in the compliance architecture it suggests for regulated dollar tokens moving forward.
Circle has been working with Deloitte on its USDC reserve attestations since early 2023, giving it a head start in establishing audited confidence. Tether’s engagement of Deloitte for USAT—even at the attestation level—signals an effort to close that credibility gap in the regulated U.S. market.
Looking Ahead
Deloitte’s attestation does not fundamentally alter the structure of USAT’s reserve holdings, but it does provide a level of third‑party verification that Tether has historically struggled to secure from major accounting firms due to reputational and regulatory risk concerns.
Whether this step will evolve into full audits for USAT or eventually extend to Tether’s broader stablecoin portfolio remains a key question for market watchers.
For now, the endorsement from Deloitte adds a new dimension to the credibility of regulated stablecoins, offering reassurance to investors and institutions that demand transparent and independently confirmed backing for dollar‑pegged digital assets.
