Bessent Steps In — Then The Market Steps Back

Treasury Secretary Scott Bessent staged a rare intervention on Wednesday.

The 30-year Treasury yield had just hit 5.27%, a 19-year high, on a mix of concerns over the $40 trillion national debt, a fiscal 2026 deficit tracking above $1.8 trillion, and heavy AI-related corporate issuance.

Two weeks after publishing its buyback schedule, Treasury announced it would “at least double” its buybacks of 10- to 30-year debt.

Long-end yields collapsed on the news — the 30-year dropped nine basis points, the 10-year 5.7 basis points. The relief lasted less than 48 hours. By Friday, the 30-year was back to 5.25%, near pre-announcement levels.

JPMorgan called the move a “band-aid” without underlying fiscal consolidation. Evercore ISI flagged the risk of a “slippery slope” if Bessent starts trying to defend specific yield levels.
