US 30-year yield hit 5.34% in mid-August, worst stretch since 2006

The US 30-year Treasury yield hit 5.34% in mid-August, according to Bloomberg-compiled data, leaving the long bond entering September 2026 on its worst run since 2006. Yield is the annual return buyers demand to hold government debt. Higher long yields tend to push up mortgages and corporate borrowing. I'd treat talk of a quick rebound with skepticism.
