• US 5- to 10-year Treasury yields rose about 10 basis points the day after the January 2026 ISM Manufacturing PMI release, driven by the index's stronger-than-expected jump to 52.6 from 47.9 prior, signaling manufacturing expansion above 50.
  • The move pushed the 10-year yield toward the upper end of its recent range (around 4.16%-4.30%), with initial post-ISM gains partially offset later by weak labor data like higher jobless claims (231k vs. 212k expected) and a flight-to-safety rally.
  • The yield curve steepened, with the 10-year/2-year spread widening to 0.73%—the widest in four years—due to Fed rate cuts lowering short-end yields (~3.49% for 2-year) while longer yields rose amid high US debt and softer Treasury demand.

US Treasury yields experienced a sharp uptick following the release of the January 2026 ISM Manufacturing PMI, which came in at 52.6, well above forecasts of 48.5 and marking a significant rebound from the prior 47.9. This stronger-than-expected data, indicating manufacturing expansion above the 50 threshold, initially drove 5- to 10-year yields up by about 10 basis points, according to market analysts. The 10-year yield approached the upper end of its recent range, hovering around 4.16%-4.30%, as investors recalibrated expectations amid signs of economic resilience.

However, the rally in yields was tempered later in the day by softer labor metrics, including higher jobless claims at 231k versus an expected 212k, which triggered a flight-to-safety rally. "The ISM beat was a clear signal of manufacturing resurgence, but it's being countered by mixed data on the labor front," said one trader familiar with the matter, who spoke on condition of anonymity. Efforts to reach the Federal Reserve for comment on the yield movements were not immediately successful.

The yield curve steepened notably, with the spread between 10-year and 2-year yields widening to 0.73%, the widest in four years. This shift reflects the dynamic where short-end yields, around 3.49% for the 2-year, have been pressured lower by anticipated Fed rate cuts, while longer yields are rising due to factors like elevated US government debt loads and subdued demand for Treasuries. In broader market trends, investment-grade corporate bond supply hit $59 billion, surpassing the $40 billion expected, with strong investor appetite, while municipal bonds saw $1.9 billion in inflows.

Political context adds another layer, as Fed Chair Powell, ahead of the May transition to Kevin Warsh, has noted that services inflation is tracking toward the 2% target, with goods prices easing post-tariffs. Although no direct policy shifts were tied to the ISM data, the softening labor metrics may amplify the Fed's focus on full employment. Societally, higher yields raise borrowing costs for mortgages, autos, and consumer loans, putting pressure on households amid sticky long-term inflation expectations, which stand at 3.4% over 5-10 years according to the University of Michigan survey.

Looking ahead, yields may dip below 4% if labor data weakens further, with the BLS report delayed post-shutdown, potentially validating rate cuts. Market participants are pricing in a 25 basis point cut in June, with another expected in the fourth quarter. In related developments, consumer sentiment rose to 57.3, beating forecasts of 55, and inflation views eased slightly, while Bitcoin fell 16.5% and equities faced pressure from sell-offs. Upcoming data includes the ISM Services index, forecast to hold steady at 53.8, and the next ISM PMI release in February 2026.
