Tether, the issuer of the world’s largest stablecoin USDT, has marked a pivotal moment in its financial reporting history by completing its first full financial statement audit. Conducted by KPMG U.S., one of the global Big Four accounting firms, the audit resulted in an unqualified opinion for Tether International, S.A. de C.V.—the company’s El Salvador-based issuing entity—for the fiscal year ending December 31, 2025. An unqualified opinion represents the highest level of assurance an auditor can deliver, signaling that financial statements present a fair and accurate view of an organization’s financial standing. However, the achievement comes with a notable caveat: Tether has chosen not to publish the audited financial statements or the accompanying opinion letter from KPMG, leaving market observers and industry analysts waiting for complete visibility into the firm’s internal finances.
From Reserve Attestations to a Full Financial Audit
For years, Tether’s financial transparency has been a central topic of discussion within the cryptocurrency ecosystem. As the primary liquidity backbone of the digital asset market, USDT commands a massive market capitalization exceeding $100 billion, facilitating billions of dollars in daily trading volume across global exchanges. Historically, Tether addressed transparency concerns by releasing periodic reserve attestations provided by independent accounting firms, including BDO Italia and MHA Cayman.
While these past attestations confirmed that Tether held sufficient backing assets to cover outstanding USDT tokens at specific points in time, they differed fundamentally from a full financial statement audit. Key distinctions include:
- Attestations: Offer a narrow snapshot of balance sheet items at a single moment, verifying asset backing without examining operational details.
- Financial Audits: Involve comprehensive examinations of an entity’s complete financial framework, including income, operating expenses, profit margins, liabilities, cash flows, and internal control systems over an entire fiscal year.
By securing a full audit, Tether has addressed a long-standing criticism regarding its accounting practices, moving beyond point-in-time reserve checks to full-year corporate accounting evaluation.
Understanding the Standards: AICPA vs. PCAOB
The audit performed by KPMG U.S. was conducted in accordance with standards established by the American Institute of Certified Public Accountants (AICPA). While AICPA standards are widely recognized across private corporate finance in the United States, they differ from the criteria set by the Public Company Accounting Oversight Board (PCAOB).
This distinction is particularly relevant amidst ongoing legislative efforts in Washington. Emerging U.S. regulatory frameworks, such as the proposed GENIUS Act and other stablecoin bills, frequently require licensed stablecoin issuers to meet PCAOB auditing standards similar to publicly traded corporations. By utilizing AICPA standards for its El Salvador entity, Tether has completed a major internal milestone, though it operates outside the scope of strict U.S. public company regulations.
The El Salvador Strategy and Corporate Structure
The entity evaluated by KPMG, Tether International, S.A. de C.V., forms a critical component of Tether’s evolving global corporate architecture. Over recent years, Tether has established strong operational roots in El Salvador, a nation that gained international attention by adopting Bitcoin as legal tender in 2021. Establishing a primary issuing entity in El Salvador has allowed Tether to navigate changing regulatory regimes while operating within a crypto-supportive legal jurisdiction.
Because the audit focused specifically on the El Salvador issuing entity rather than a single unified global parent company, analysts note that understanding Tether’s overall risk profile still requires insight into how reserves, capital, and liabilities are distributed across its network of international subsidiaries.
Why the Secrecy Surrounding the Report Matters
Despite the significance of obtaining an unqualified opinion from a Big Four firm, Tether’s decision to withhold the financial statements and audit letter has generated debate among digital asset researchers and institutional investors. In traditional financial markets, an unqualified audit opinion is accompanied by public disclosures of balance sheets, income statements, and operational notes.
Without access to these financial disclosures, market participants cannot independently verify details such as:
- Exact breakdown of net income and operational costs.
- Total contingent liabilities and corporate debt structures.
- Specific yield generation mechanisms on reserve assets.
Industry observers contend that releasing the full documentation would provide unprecedented validation for USDT, helping eliminate residual skepticism from traditional banking partners and global regulators.
Broader Implications for Stablecoin Markets
Tether’s audit announcement arrives at a critical juncture for the stablecoin industry. Regulatory bodies worldwide are implementing stricter regimes, such as the European Union’s Markets in Crypto-Assets (MiCA) framework, which demands elevated liquidity, reserve, and governance disclosures. Simultaneously, main competitors like Circle, the issuer of USD Coin (USDC), continue to emphasize public transparency and regulatory alignment as core differentiators.
Driven by higher interest rates on its extensive holdings of U.S. Treasury bills, Tether has reported record profitability in recent quarters, positioning it among the most profitable companies per employee globally. Achieving a clean audit report from KPMG reinforces its narrative of institutional strength. If Tether eventually chooses to publish the full financial report, it could mark a transformative moment for institutional trust and integration across centralized finance, decentralized platforms, and global banking systems.
Conclusion
Tether’s successful completion of a full financial audit by KPMG U.S. represents a significant structural milestone in its corporate history. Earning an unqualified opinion demonstrates that the financial reporting of its El Salvador issuing entity aligns with rigorous AICPA accounting standards. However, until Tether chooses to release the complete audit documentation and financial figures to the public, the crypto community and international regulators will continue to monitor the company’s disclosures closely. The milestone marks undeniable progress toward traditional financial auditing standards, even as the request for full public visibility remains open.
