There’s a number that came out Monday that barely made the evening news. It should have. China’s U.S. Treasury holdings: $633 billion. Back in November 2013, that number was $1.317 trillion. China was the single biggest buyer of American government debt. More than Japan. More than anyone on earth.

They’ve cut their position in half.

The Treasury Department’s latest international capital data shows the three biggest foreign holders — Japan, the UK, and China — all sold in June. Combined, $61 billion out the door in one month. Net foreign inflows specifically into Treasuries collapsed 88%... from $56.6 billion in May to just $6.8 billion in June. (Total net capital inflows into all U.S. assets actually ticked up to $133.5 billion — but the appetite for government debt is what shifted.) China stands out. They dumped 4% of their remaining holdings in a single month. That brings them to the lowest level since September 2008. Before the financial crisis even started. And the pace is picking up — look at the chart. The bars get shorter... and the gaps between them get bigger.

Now... most people think this is just trade-war politics. That’s part of it. Here’s what most people get wrong. China isn’t just selling our bonds. They’re buying something else. Gold. Central banks worldwide bought over 1,000 tonnes of gold a year for three straight years through 2024 — a pace not seen since the 1950s. China was among the biggest single buyers in 2023; Poland and India have led more recently. That’s not routine portfolio trimming. That’s a coordinated bet away from dollar reserves.

And here’s the part that really gets me. The U.S. ran a $1.8 trillion deficit in fiscal 2025, and net interest on the debt crossed $1 trillion for the first time. Somebody has to buy all that new paper. When the biggest foreign buyers slow down — and they are — interest rates have to rise to attract new money. That’s not a theory. That’s supply and demand. Even Japan, the largest foreign holder at $1.116 trillion, is well off its own peak of $1.325 trillion from November 2021.

This doesn’t mean a crisis next Tuesday. But the cost of borrowing for the United States is going one direction. And that cost gets passed to you — in mortgage rates, car loans, and every bond in your portfolio.

If you own long-duration bonds or you’re planning to refinance anything in the next year or two, keep your eye on this trend. The foreign bid for U.S. debt is thinning at the margin. That’s worth a conversation with your advisor this week — not next month.
