10-year Treasury yield tops 5.1% as bond selloff deepens

The 10-year U.S. Treasury yield rose above 5.1% on Sept. 23, 2026, WSJ reported, as selling in government bonds deepened. The yield — the return lenders demand to hold U.S. debt — helps set mortgage and loan rates. Higher yields can mean costlier borrowing and pressure on stocks. I see the speed of the move as the risk to watch.
