Treasury yields spike after $6 billion buyback plan announced
Bessent, speaking at an SMU Cox School of Business fireside chat Tuesday, framed the buybacks as a mechanism to make market participants “get out of their fever dream and look at the facts.”
Markets responded by sending yields higher. The actual buyback operation is scheduled for Thursday in a 20-minute window concluding at 2 p.m. ET.
What the spike means for mortgage rates
For US mortgage brokers, Wednesday’s moves are the latest chapter in a deteriorating rate story. US mortgage rates are inching toward 7%, driven by a convergence of pressures — a national debt that has surpassed $40 trillion, tariff-fueled inflation, and an Iran conflict that sent Brent crude above $100 a barrel Wednesday for the first time since late July.
Bond yields climbing throughout 2026 have repeatedly raised the prospect of renewed mortgage rate pressure, a pattern Thursday’s operation will either interrupt or confirm.
Marc Ostwald, chief economist and global strategist at London’s ADM Investor Services, captured the bind in a Wednesday note: “Rates and FX markets are facing an ever more complex environment, with the risks of high energy prices spilling over more broadly in inflation terms, but in turn also increasing the risks of growing headwinds to growth, and demand destruction.”
