Tether claims 650 million users decentralize US debt, but reserves stay centrally controlled

Paolo Ardoino, Tether’s chief technology officer, said the stablecoin’s 650 million users collectively hold U.S. Treasury bills, framing the network as a decentralized owner of U.S. debt. The comment highlights concentration risk in traditional foreign‑government holdings, but the legal and economic structure of USDT remains issuer‑mediated.

How Tether defines user ownership

Tether’s documents state that users own the USDT token and have a contractual right to redeem it for fiat, provided they are verified customers. The reserve assets, including Treasury bills, are owned and managed by Tether International, which can change the portfolio composition at its discretion.

Reserve composition and scale

As of June 30, Tether reported $187.751 billion in reserve assets against $183.642 billion in liabilities. The reserve includes $114.961 billion of direct U.S. Treasury bills and $18.626 billion of overnight reverse‑repo exposure collateralized by U.S. Treasuries.

Limits on holder rights

USDT holders are entitled only to redemption at face value, less fees. They do not receive any gains from the reserve portfolio above the token’s nominal value. Direct redemption requires verification, a $100,000 minimum transaction size, and is subject to Tether’s discretion.

What the 650 million figure represents

Tether’s internal methodology uses on‑chain addresses and estimates of users on centralized services to arrive at a broad upper‑bound count. The figure does not represent an independent count of unique Treasury investors or verified redeemers.

Implications for US debt markets

Broad demand for USDT creates a dispersed source of funding for short‑term U.S. Treasury bills, but the legal title, portfolio control and any upside from the assets remain with Tether. The stablecoin therefore decentralizes the distribution of a dollar claim, not the ownership or control of the underlying debt.
