Tether's New Stablecoin Audited by Deloitte, But USDT Reserve Concerns Remain

Tether has for the first time engaged a Big Four auditing firm to verify its stablecoin reserves, but this audit only covers its newly launched US-compliant stablecoin, USAT, and not the market-leading USDT. While this development is significant, it fails to address long-standing doubts about the reserve transparency of USDT, which have persisted for a decade.

USAT is issued by Anchorage Digital, the first federally chartered crypto bank in the United States. Tether CEO Paolo Ardoino positions it as an extension of USDT aimed at the US institutional market, rather than a replacement. The two are completely independent in terms of legal structure, regulatory framework, and operating entity. The audit report dated January 31, 2026, shows that all of USAT's reserves (approximately $17.6 million) are held in independent trust accounts, free of any collateral obligations, and are committed to 1:1 redemption, in compliance with AICPA 2025 stablecoin reporting standards. Deloitte's conclusion confirms that management's representations regarding the reserve report are fairly presented in all material respects.

This marks the first time a Big Four auditing firm has provided public endorsement for any asset within the Tether ecosystem, breaking the long-standing deadlock where multiple accounting firms refused to participate in USDT audits due to reputational concerns. This move is seen as an important step in enhancing institutional trust, and USAT's market capitalization has climbed to nearly $20 million since its launch, indicating initial market acceptance. However, this audit is unrelated to USDT. As the world's largest stablecoin by market capitalization, USDT currently has a size of approximately $189 billion, and its reserves still rely on quarterly attestations from the Italian firm BDO, without publicly disclosing detailed asset composition. Deloitte's audit was only a sample check at a single point in time and does not involve a comprehensive financial audit. USAT's reserve size is only about one ten-thousandth of USDT's, making the two incomparable. Therefore, while USAT's transparency represents a crucial step forward, the core market concern—whether USDT is truly fully, compliantly, and transparently backed—remains unresolved. Only when Deloitte or a similar institution issues an audit report on USDT itself can genuine trust rebuilding begin.
