Key takeaways

  • A jump in oil to $109 a barrel reignited a global bond sell-off, pushing US yields to the highs of the day.
  • Scott Bessent's Treasury buyback operation fell short of its target, adding a supply-side dimension to the bond sell-off.
  • A buyback that undershoots leaves more duration in the market than the operation planned to absorb.
  • Both catalysts — crude at $109 and the buyback shortfall — pushed in the same direction, strengthening bond sellers.
  • Whether the crude move holds at the $109 level is the key macro caveat for rates.

Oil's jump to $109 a barrel reignited a global bond sell-off, with US yields climbing to the highs of the day. The rate move gathered pace after Scott Bessent's Treasury buyback operation fell short of its target, adding a supply dimension to a session that crude had already tilted against bond holders.

The two catalysts ran in the same direction. A buyback that undershoots leaves more duration in the market than the operation had planned to absorb; oil at $109 had already given rates desks a live signal to trade. Together, they put sellers in the bond market on firmer footing.

Energy at $109 applied pressure from the commodity side. The Bessent shortfall applied it from the supply side. Against the backdrop of the broader sell-off cycle, the combined effect registered cleanly in the session's highs for US yields. The macro caveat is whether the crude move holds at that level.
