CNBC — Week of 2026-08-15 to 2026-08-21

Story of the Week

A combined geopolitical shock from Strait of Hormuz shipping attacks and the U.S. national debt crossing the $40 trillion mark triggered a severe global bond market rout, sending the U.S. 30-year Treasury yield to a 19-year peak of 5.33%. To stabilize the market, Treasury Secretary Scott Bessent launched an upscaled $4 billion-plus debt buyback program, which briefly rallied equities before ultimately failing to contain the rise in yields. This failed intervention has heightened inflation concerns, sending major stock indexes to snap a three-week winning streak and setting up a high-stakes Jackson Hole meeting for newly-installed Fed Chairman Kevin Warsh.
