Tether announced this week that KPMG U.S. has completed an independent audit of its financial statements for the year ending December 31, 2025, the first time a Big Four accounting firm has conducted a full financial review of the El Salvador-based company behind USDT. The auditor issued an unqualified opinion, meaning the financial statements were found to present fairly in all material respects. The audited reserve surplus stood at $6.814 billion. Tether has not released the underlying financial statements to the public.

The distinction between this audit and Tether's prior work matters. For years, the company published quarterly attestations performed by BDO Italia. An attestation confirms a specific claim on a specific date; it does not independently verify internal controls, accounting methodologies, or counterparty exposure across a full reporting period. KPMG's engagement covered the complete balance sheet, income statement, equity changes, and cash flows. Auditors also physically counted and inspected individual gold bars held in custody rather than accepting custodian reports at face value. Tether calls it the "largest inaugural financial audit in history" by dollar value covered. CEO Paolo Ardoino framed the completion as a landmark achievement. "For years, some said an audit of Tether could not be completed," he said. "We have once again proven them wrong."

CoinDesk reported it had not received a response from Tether on the question of public disclosure. That gap matters: the headline opinion and the surplus figure are not substitutes for the underlying notes, which would detail reserve composition, related-party transactions, and accounting policy choices. The audit opinion also says nothing about redemption capacity, liquidity under stress, or counterparty concentration. These are precisely the risks most relevant to the USDT peg holding during a market shock, and they are distinct from the question of reserve surplus level.

There is a second number that deserves attention alongside the audited surplus. Tether's Q2 2026 quarterly attestation, published July 31, showed the reserve buffer had contracted to $4.11 billion, down roughly 40% from the $6.814 billion figure KPMG confirmed as of December 31, 2025. This occurred even as Tether reportedly booked approximately $1.5 billion in net operating profit during the first half of 2026. Analysts point to two likely causes: gold prices fell more than 20% from their January 2026 peaks, and Bitcoin holdings generated unrealised losses. Tether holds approximately $8 billion in gold and $7 billion in Bitcoin alongside roughly 80% of reserves in U.S. Treasuries. One additional complication for analysts: the legal entity audited by KPMG (Tether International, S.A. de C.V.) does not map precisely to the entity covered in quarterly group-level attestations, making direct comparisons imprecise.

Regulatory context and the foreign-issuer gap

The audit arrives amid overlapping regulatory developments and a legacy of enforcement actions. The GENIUS Act, signed into law in July 2025, requires U.S.-domiciled stablecoin issuers to obtain annual audits, publish monthly attestations, and maintain one-to-one reserve backing. Tether, incorporated in El Salvador, is not legally subject to those requirements. The company pursued this audit voluntarily. A separate bill, the Foreign Stablecoin Transparency Act (S.3907), reintroduced by Sen. Jack Reed, would extend similar obligations to foreign issuers operating in U.S. markets, but the legislation has not advanced. By way of background, Tether settled with the New York Attorney General in 2021 for $18.5 million over allegations it misrepresented its reserves, a case that first elevated scrutiny of its attestation-only approach. The CFTC issued a separate order against Tether the same year.

What it means outside the United States

USDT currently has a circulating supply of approximately $189.77 billion as of mid-2026, representing about 58.65% of the $323.4 billion total stablecoin market. About 97% of that supply sits on two blockchains: Ethereum and Tron. Tron's TRC-20 network carries more than half of total USDT supply, largely because transaction fees run under $0.001, making small transfers economically viable.

That cost structure matters most in regions where USDT has become functional infrastructure. India ranks first globally in stablecoin adoption according to the Chainalysis 2025 Global Crypto Adoption Index, with between 93 and 119 million crypto holders relying on USDT for remittances and as a dollar-denominated savings tool. Pakistan, ranked third globally, has roughly 15.9 million crypto users; chronic inflation above 25% and a freelance workforce of approximately 10 million have pushed many toward stablecoin payments over the Pakistani rupee. Stablecoin transaction volume across South Asia grew approximately 80% year-over-year in the 2024 to 2025 period, reaching roughly $300 billion. In Sub-Saharan Africa, stablecoin transaction volume grew 52% year-over-year in 2025. Nigeria, where inflation has exceeded 30%, uses USDT widely as a savings vehicle. Yellow Card processed more than $6 billion in stablecoin volume across more than 35 African countries in 2025.

The audit carries direct regulatory relevance in these markets. Regulators in Nigeria, Kenya, and India have cited audit-grade transparency as a key requirement for enabling formal licensing of USDT-based payment rails, and the KPMG opinion provides the institutional credibility signal that regulators in New Delhi, Islamabad, and Dhaka may need to move forward. An unqualified Big Four opinion is precisely the kind of documentation that AML and central bank compliance teams in those jurisdictions understand. Tether has also made a strategic investment in LemFi, a cross-border payments platform targeting African and Asian diaspora corridors, with USDT positioned as the settlement layer across 30-plus countries. LemFi reports settlement times under one minute and cost reductions of approximately 45% compared with SWIFT transfers.

The road forward depends on disclosure. Tether has cleared the credibility bar set by a Big Four audit, which is a meaningful step after years of scrutiny. But several gaps remain. The audit opinion does not address liquidity under stress or Tether's capacity to meet large-scale redemptions in a market shock. The entity audited by KPMG, Tether International, S.A. de C.V., does not map precisely to the entity covered in group-level quarterly attestations, leaving an unresolved mismatch that complicates ongoing monitoring. Whether regulators and market participants treat the audit as sufficient will depend partly on whether the underlying financial statements ever become available for independent review, and on whether the reserve buffer stabilises after its post-audit decline.
