Key Takeaways
- • Short positioning in US Treasuries surged ahead of the Federal Reserve's September 2026 meeting, with JPMorgan's client survey showing shorts increasing 10 percentage points to reach 14% in the week ending September 14, marking the lowest net long positioning in approximately four months.
- • The 10-year Treasury yield climbed to its highest level since 2007, while the two-year yield reached its highest point since 2024, driven by elevated inflation expectations and geopolitical oil price pressures following the Iran conflict.
- • Markets are pricing a greater than 90% probability of a 25-basis-point rate increase at the September Fed meeting, which would represent the first US rate hike since 2023, reflecting investor expectations that persistent inflation will compel monetary policy tightening.
- • Treasury futures short positioning increased both before and after last week's stronger-than-expected inflation data, according to CME Group open-interest figures, signaling sustained bearish conviction among institutional investors.
- • Rising oil prices, persistent inflation concerns, and deteriorating US fiscal policy outlook have converged to shift investor sentiment from neutral positioning toward outright bearish Treasury positioning.
Summary
Bond investors have established pronounced bearish positions across the US rates complex ahead of this week's Federal Reserve meeting, as multiple macro pressures converge to support expectations for higher interest rates and elevated Treasury yields. According to a Bloomberg report, the positioning shift reflects growing conviction that renewed inflation momentum will force the Fed to abandon its current monetary policy stance and resume rate increases for the first time since 2023.
Yield moves have been pronounced across the curve. The 10-year Treasury yield reached its highest level since 2007 on Tuesday, while the two-year yield climbed to its highest point since 2024. This sharp upward repricing has been accompanied by a dramatic increase in short positioning, with investors demonstrating reluctance to accumulate government debt following the recent Treasury selloff. JPMorgan's latest client survey provides quantitative evidence of the positioning shift: short positions increased by 10 percentage points in the week ending September 14, with the survey now showing its lowest level of net long positioning in roughly four months. The shift was primarily driven by investors transitioning from neutral positions into bearish shorts, suggesting a meaningful change in conviction rather than a continuation of existing trends.
Market pricing reflects these positioning dynamics and underlying macro concerns. CME Group open-interest figures confirm that investors have added to Treasury futures shorts both before and after last week's stronger-than-expected inflation data, demonstrating that the positioning response extends beyond any single catalyst. Markets are now pricing a greater than 90% probability of a 25-basis-point rate increase at the September Fed meeting. The combination of higher oil prices following the Iran conflict, persistent inflation signals that suggest price pressures are not transitory, and deteriorating US fiscal policy concerns have all contributed to the significant repricing of rate expectations and the corresponding surge in Treasury short positions.
