Japan's Treasury buying collapsed 99%: what that means for yields
As seen on the 24/7 Wall St. homepage on October 28, 2026.
The biggest foreign buyer of U.S. government debt has essentially stepped away, which leaves domestic buyers to absorb supply and puts the burden on yields. Keep an eye on the long end of the curve and the dollar.

Japan is the largest foreign holder of U.S. Treasuries, which makes its buying behavior one of the most consequential signals in the global bond market. Through August, that buying came to just $389 million, a 99% drop from the same period a year earlier.
When the single largest foreign source of demand for U.S. government debt pulls back this sharply, the supply that Japan used to absorb has to go somewhere. Domestic buyers must step in to fill the gap, and the price they demand for doing so typically shows up as higher yields, particularly at the long end of the curve.

The long end, meaning longer-dated maturities like the 10-year and 30-year Treasury, is where this kind of demand shift hits hardest. A sustained rise in those yields ripples through mortgage rates, corporate borrowing costs, and equity valuations, so the bond market is the place to watch for the next leg of this story.
The dollar is the other variable to keep in focus, since reduced Treasury purchases mean fewer dollars recycled back into U.S. assets. Rising yields alongside a softer dollar would be an uncomfortable signal for markets to absorb.
