The US Treasury has released its Treasury International Capital report for March 2026, showing a total net foreign capital inflow of $150.7 billion — encompassing purchases of long-term securities, short-term instruments, and banking flows.

The breakdown reveals a clear divide between private and official investors. Foreign private investors drove a net inflow of $162.1 billion, while foreign official institutions — including central banks and sovereign wealth funds — recorded a net outflow of $11.4 billion, indicating that state-level actors were net sellers of US assets in March even as private capital continued to flow in.

In the long-term securities segment, foreign residents made net purchases of $96.5 billion overall. Private foreign investors accounted for $111.4 billion in net buying, while official institutions recorded net sales of $14.9 billion. Adjusted for estimated foreign portfolio acquisitions of US equities through swap arrangements, total net foreign purchases of long-term securities reached $81.3 billion for the month.

On the other side of the ledger, US residents increased their exposure to foreign long-term securities, recording net purchases of $15.2 billion.

In short-term instruments, foreign investors trimmed their holdings of US Treasury bills by $16.8 billion. However, total foreign positions across all dollar-denominated short-term US securities and custody liabilities edged up by $1.3 billion. Net dollar liabilities of US banks to foreign residents rose by $68.1 billion.

The next TIC data release, covering April 2026, is scheduled for June 18.
