Foreign Investors Shift US Investment: Stocks Over Treasury Bills, Stablecoins Emerge as Potential Demand Source

Foreign investors sent a net $133.5 billion into US financial markets in June, with a notable shift towards stocks over Treasury bills. The Treasury International Capital (TIC) report showed $181.4 billion in US equity purchases, contrasting with a $29 billion sale of short-term Treasury bills. This dichotomy reflects a selective allocation, favoring ownership in American companies over government debt, particularly at the short end.

The reduction in foreign holdings of short-term Treasuries, from $1.430 trillion in May to $1.400 trillion in June, marks a 2% decrease and the second consecutive monthly reduction. While the reasons behind these sales are unclear—potentially due to routine cash management or preference for other assets—the data underscores a weakening demand for cash-like government debt.

Stablecoin issuers, such as Tether and Circle, have emerged as significant holders of Treasury bills, with Tether alone holding $114.96 billion in direct Treasury bills and $25.62 billion in repo positions as of Q2. The mechanism by which stablecoins indirectly demand Treasury bills (through issuer investments) positions them as a potential future demand source, especially if their circulation expands. Current stablecoin market size (near $302.1 billion) and minimal growth in Tether’s USDT circulation suggest that while new token creation did not directly absorb the $29 billion bill sale, the stablecoin market’s structure inherently links stablecoin demand to Treasury bill demand.

Washington’s increasing regulatory support for stablecoins, notably through the GENIUS Act and proposed rules favoring liquid reserves (cash, short Treasury obligations), further integrates stablecoins into the US financial system. This regulatory environment could enhance stablecoins’ role in government debt financing, particularly at a time of softened foreign demand for short-term Treasuries.

Key numbers to watch in future TIC reports include changes in foreign bill holdings and stablecoin circulation. A sustained decrease in foreign Treasury bill ownership coupled with growing stablecoin activity could signal a shift towards stablecoins as a substantial buyer of US government debt.
