On the third Tuesday of every month, the U.S. Department of the Treasury releases the Treasury International Capital (TIC) data — the official record of cross-border capital flows in and out of U.

S. financial assets (per home.treasury.

gov/data/treasury-international-capital-tic-system). The TIC release is one of the most under-followed major macroeconomic data series, because it lacks the immediate market-moving impact of an FOMC statement or a CPI print, but it carries the structural picture of how foreign investors are allocating capital into U.S.

Treasuries, agency securities, equities, and corporate bonds. Per recent TIC monthly releases (the most recent data shown here as approximate, with substantial month-to-month variation): Japan is the largest single foreign holder of U.S.

Treasury securities at approximately $1.1 trillion (per TIC, varying by ±$50-100B across recent months); China is the second-largest at approximately $770 billion (down from a peak of approximately $1.3 trillion in 2013); the United Kingdom holds approximately $700-750 billion; Cayman Islands ~$300-400 billion (largely a domicile for offshore funds, not a sovereign holder); other major holders include Belgium (custodial holdings often associated with Russian / Eurozone official reserves), Switzerland, Luxembourg, Ireland, Brazil, India, Saudi Arabia.
