Tether aims to become a top-five buyer of US Treasuries

Tether holds over $122 billion in US Treasury bills and aims to become a top five buyer, a shift that reshapes both the stablecoin and the government debt markets⁶. Its chief executive has set out that top five ambition explicitly^2,4.

Tether, the issuer of the world’s largest stablecoin USDT, already ranks among the top buyers of US government paper on the strength of those holdings⁸. The mechanism is simple: every USDT token in circulation needs to be backed by reserves, and Tether has chosen to park the vast majority of those reserves in Treasuries⁵.

The scale

The reserve pile has been growing. Tether’s exposure to US Treasuries surpassed $141 billion by the end of 2025³, and the company argues that its position strengthens the Treasury market rather than straining it³.

Set against the reported bill holding of over $122 billion, the end-of-2025 exposure figure of more than $141 billion shows how quickly the position has been built^3,6. A buyer of that size is no longer a curiosity at the short end of the curve.

The industry’s own projection is larger still. Stablecoin regulation could create an additional $2 trillion in Treasury demand³. Cryptonews frames the shift as enhancing the stablecoin’s role in the broader financial ecosystem and as evidence of changing market dynamics², while Coinfomania points to rising interest from traditional financial institutions⁴.

Why investors should care

A stablecoin issuer as a marginal buyer ties bill demand to crypto trading volumes, and that link runs in both directions. Tether’s growing role in US Treasuries could stabilise demand, but it risks market disruption if rapid redemptions occur, with knock-on effects for the wider financial system⁷.

The downside case is already being discussed on the funding side. A slowing stablecoin market, following a downturn in cryptocurrency trading, could dampen the US Treasury’s plan to sell government debt¹. In other words, a crypto drawdown would arrive at the auction as a smaller bid.

The reflexivity is the point. Reserves grow when tokens are issued, which happens when trading is active, and shrink when holders redeem^5,8. That makes a portion of the buyer base for short-dated government paper procyclical with an asset class that has no obligation to the funding calendar. For anyone modelling bill demand, Tether is now a line item worth naming rather than a rounding error⁶.
