USDT has developed into a global dollar network used by more than 530 million people, giving its issuer an unusual role in channeling demand for U.S. government debt.

Tether reported more than 530 million users at the end of 2025. Its latest market data showed that on-chain USDT holders alone had reached approximately 140 million, while more than 100 million additional users were estimated to hold USDT through centralized exchanges.

That scale is central to Tether CEO Paolo Ardoino’s argument that USDT is helping distribute U.S. debt ownership across hundreds of millions of users.

The arrangement does not mean those users directly purchase Treasury bills. Instead, they hold USDT while Tether holds the assets backing the tokens. As of March 31, 2026, Tether reported approximately $141 billion in direct and indirect exposure to U.S. Treasury bills. Reuters separately reported that the company held about $117 billion in Treasury bills in its reserves.

The distinction is significant: USDT users are distributed across the world, but the Treasury exposure remains concentrated on Tether’s balance sheet.

The structure gives USDT holders dollar exposure without requiring them to individually own Treasury securities. Tether, meanwhile, earns income from the assets backing the tokens. The Bank for International Settlements (BIS) has highlighted the broader trend, noting that stablecoin issuers’ holdings of Treasury bills have grown to levels comparable with those of large jurisdictions and government money-market funds.

Tether’s model therefore places the company between global dollar users and the U.S. Treasury market. Hundreds of millions of people create demand for USDT, while Tether aggregates the resulting reserve pool into a concentrated Treasury portfolio. In economic terms, that makes the exposure to the debt much more broadly distributed than ownership of the securities themselves.

For policymakers and market observers, the relevant distinction is therefore between the breadth of USDT’s user base and the concentration of its reserve assets. User growth can expand the network without changing who legally holds the Treasury bills, making Tether’s reported reserve composition and disclosures central to understanding that relationship.

Ardoino has previously described the company’s role in emerging markets as “basically pushing dollar hegemony, selling U.S Debt outside the U.S.” His comments were reported by BitcoinKE.

The scale of stablecoin holdings has also prompted discussion about their potential role in the Treasury market. A BitcoinKE report examined the possibility that Tether ($USDT) and Circle ($USDC) could become major buyers of U.S. debt if the stablecoin market expanded substantially. Separately, U.S. national debt surpassed $40 trillion for the first time, according to a milestone reported by the publication.

These developments illustrate how stablecoin reserves can connect a globally distributed user base with a highly concentrated portfolio of U.S. government securities.
