Tether Pursues Independent Audit for USDT Reserves Amid Regulatory Pressure
Tether, the issuer of the widely used stablecoin USDT, has announced the engagement of an unnamed Big Four accounting firm to conduct its first comprehensive independent audit of reserves worth approximately US$192 billion (AU$275 billion) that back the cryptocurrency. This announcement, made on March 24, has reignited discussions on Tether’s commitment to transparency and regulatory compliance, a subject of scrutiny since the company’s inception.
Tether boasts a market capitalisation of around US$184 billion (AU$263 billion), yet the specifics of the audit remain murky. The company did not disclose the identity of the chosen firm or provide a timeline for the audit’s completion. Tether’s Chief Executive Officer, Paolo Ardoino, stated that this initiative aims to enhance confidence in their reserve infrastructure. Furthermore, Chief Financial Officer Simon McWilliams indicated that the selection process for the auditing firm was competitive and that initial onboarding tasks, such as system reviews and controls, have already been finalised.
The need for a full audit has become pressing following past failures to deliver on similar commitments. Tether’s previous attempt in 2017 with Friedman LLP ended without a final report, and Ardoino noted challenges in securing a Big Four firm in the years following. Until now, Tether’s approach to transparency has largely relied on quarterly attestations from BDO Italia, which offer limited assurance as they represent a snapshot in time, contrasting with the rigorous examination expected from a full-scale audit.
The company’s efforts come in response to heightened regulatory expectations. The GENIUS Act, enacted in July 2025, mandates that foreign stablecoin issuers processing more than US$50 billion (AU$71 billion) in volume must undergo annual reserve audits. Tether firmly exceeds this threshold, further intensifying the scrutiny surrounding its reserve claims.
Tether asserts that the majority of its reserves are held in US Treasury bills, alongside smaller allocations in Bitcoin, loans, and about 148 tonnes of physical gold, valued at approximately US$23 billion (AU$32 billion). Historical context is essential; Tether’s reserve practices have been under a microscope for years. In 2021, the company settled with the New York Attorney General for US$18.5 million (AU$25 million) after allegations of misleading statements regarding its backing. The Commodity Futures Trading Commission (CFTC) also imposed a US$41 million (AU$58 million) fine over overstated dollar reserves, highlighting the necessity for greater transparency.
As Tether embarks on this audit, it is poised to face one of its most significant tests of transparency yet. The promise of a full independent audit could mark a turning point in Tether’s narrative; however, without the disclosure of a firm name or a specified deadline, skepticism remains. Market observers are keen to see how this decision will unfold and influence the broader landscape of cryptocurrency regulation and trust.
In summary, while Tether’s engagement of a Big Four firm signals a step towards stronger accountability, the absence of specifics raises questions. The company’s ability to navigate this audit successfully could reshape perceptions and regulatory frameworks surrounding stablecoins in the evolving digital currency landscape.
