Tether Gets First Full Big Four Audit After Years of Reserve Doubts
Tether has completed its first full financial statement audit, ending one of the longest-running transparency questions around the world's largest stablecoin issuer.
Key Takeaways
- KPMG issued Tether a clean audit opinion.
- Reserves exceeded liabilities at year-end.
- KPMG physically inspected Tether’s gold holdings.
- The complete signed audit is not public.
The scale makes the milestone difficult to dismiss as a routine accounting exercise. Tether has grown into one of the world’s largest holders of U.S. government debt, with more than $140 billion in Treasury exposure, while USDT sits at the center of a stablecoin market used across exchanges, payments and emerging markets.
Tether announced on August 13 that KPMG U.S. audited Tether International, S.A. de C.V. for the year ended December 31, 2025 and issued an unqualified opinion. The audited accounts showed reserves exceeding liabilities by $6.814 billion, while KPMG examined the balance sheet, income statement, cash flows, changes in equity and the records supporting them.
KPMG Went Beyond Tether’s Previous Reserve Reviews
Tether has published quarterly reserve attestations through BDO for years, while Deloitte separately reviewed the reserves behind Tether-linked USA₮ earlier in 2026. Those engagements focused on specified reserve information. KPMG instead audited Tether International’s annual financial statements, including transactions, systems, ownership records, valuations and counterparties across the wider business.
Tether’s balance sheet now spans U.S. Treasuries, gold, Bitcoin, secured loans and other investments. The company has also become one of the world’s largest holders of U.S. government debt, making the quality and liquidity of those assets increasingly important alongside their total value.
KPMG Physically Inspected Tether’s Gold
Tether says KPMG physically counted and inspected every individual gold bar it held, including identifying information attached to each bar. Rather than relying solely on internal ledgers or custodian statements, the physical inspection provided independent proof that the gold recorded in the accounts actually exists.
What the Clean Opinion Covers
KPMG issued an unqualified opinion on Tether’s 2025 financial statements, finding no material issue that required a qualification to its opinion.
Tether says the accounts were prepared under U.S. GAAP and the audit was conducted under AICPA auditing standards. Descriptions circulating online that call it a PCAOB audit go beyond what Tether has disclosed.
The opinion covers the financial statements for the year ended December 31, 2025. It does not guarantee that USDT will always maintain its peg or remove market and liquidity risk from the assets held after that date.
Asset Quality Still Matters
Tether’s excess reserves provide room to absorb losses, but the strength of that protection depends on the portfolio underneath them. Short-term Treasuries carry very different liquidity and volatility characteristics from Bitcoin, gold or secured lending. With Tether now managing a much broader investment portfolio, the mix, maturity and liquidity of those holdings matter alongside the headline size of the balance sheet.
The Audit Comes After Years of Scrutiny
A Big Four opinion carries particular weight for Tether because doubts over the quality and accuracy of its backing disclosures have followed the company for years.
In 2021, the U.S. Commodity Futures Trading Commission ordered Tether to pay a $41 million penalty over statements concerning USDT’s backing. The regulator found that Tether had represented USDT as fully backed by corresponding fiat reserves during a period when that was not consistently the case.
The CFTC also cited earlier statements about professional audits when Tether had not completed one.
KPMG’s opinion does not change what happened during that period. It does remove a criticism that followed Tether for years: the company can no longer be accurately described as having never completed a full annual financial audit.
The Full Report Still Needs to Be Published
Tether’s announcement describes KPMG’s opinion and the scope of its work, but the complete signed audit report and audited financial statements are not attached.
Those documents would provide much more detail on asset classification, valuation methods, accounting policies, related-party exposure and areas where management judgment was required. Until they are published, outside readers cannot examine the full notes behind KPMG’s opinion for themselves.
Tether also says its products are used by more than 650 million people. That number comes from the company and should not be presented as a user count independently verified by KPMG.
What Comes After Tether’s First Audit
A clean financial audit does not settle separate regulatory questions around USDT. Reserve requirements, permitted assets and rules for foreign stablecoin issuers still apply independently of KPMG’s opinion. U.S. stablecoin rules could therefore affect USDT even with stronger financial reporting.
The next benchmark is whether Tether publishes the complete audited statements and repeats the process every year.
If annual Big Four audits become routine rather than exceptional, Tether will have done more than answer a long-standing criticism of its own reserves. It will have raised the transparency standard that every major stablecoin issuer will increasingly be measured against.
