Tether has moved from a mixed-asset backing model to a portfolio dominated by short-term U.S. government securities. After regulators penalised the firm for overstating its dollar reserves, it announced in late 2022 that it would replace commercial paper with Treasury bills. This change addressed the need for highly liquid assets that can be quickly turned into cash when users redeem USDT, while also providing a clearer picture for auditors. An audit by KPMG of its 2025 financial statements gave the company an unqualified opinion, marking a departure from earlier years when the lack of audited statements was a major criticism.
Size of the Treasury position
According to the latest reserve disclosure, Tether directly owns roughly $115 billion of Treasury bills, representing the bulk of its short-term assets. The total reserve pool stands at about $188 billion, with liabilities of $184 billion, leaving a modest surplus. Besides Treasury bills, the reserve includes around $19 billion in overnight reverse-repo agreements, $19 billion in precious metals, $5.8 billion in Bitcoin, and $13.5 billion in secured loans. The weighted average maturity of the Treasury holdings is under 90 days, underscoring the firm’s focus on liquidity.
Political and policy relevance
Washington’s interest in Tether stems from two complementary factors. First, the stablecoin’s dominance—over 60% of the stablecoin market as of June—means it channels a large volume of dollar demand through a private channel that reaches users outside traditional banking. Second, by buying Treasury bills, Tether becomes a reliable, recurring purchaser of U.S. debt without the government having to manage the retail distribution itself. Recent reports suggest the U.S. administration is exploring an overseas stablecoin program that could involve public-private partnerships to promote dollar usage and Treasury demand, although no formal agreement with Tether has been announced.
The firm’s network effectively extends the reach of the dollar to individuals who may lack access to conventional banking services. Users can acquire USDT instantly on digital platforms, use it for payments, or convert it to local currencies, thereby reinforcing the dollar’s global role. While the Treasury purchases do not directly reduce the national debt, they provide a steady source of funding for short-term borrowing needs and embed American financial infrastructure within the crypto ecosystem.
Why it matters
Tether’s transformation into a major holder of U.S. Treasury bills illustrates how a private stablecoin can become an integral part of sovereign debt markets. The arrangement benefits both parties: the U.S. government gains a dependable buyer for short-duration securities, and Tether secures low-risk assets that support confidence in its token. For users, the link between digital dollars and U.S. Treasury debt reinforces the stability of USDT, while also tying their everyday transactions to broader fiscal policy considerations. As policymakers contemplate leveraging stablecoins to extend dollar influence abroad, Tether’s model may serve as a template for future collaborations between regulators and crypto firms.
