Bond Yields Spike Amid Rising Oil Prices and Middle East Tensions

The third quarter of 2026 saw a significant surge in government bond yields alongside record diesel prices and oil exceeding $100 a barrel. Global stock markets, however, continued their upward trajectory driven by strong corporate earnings. Investors are now closely monitoring inflation trends, central bank decisions, and escalating tensions in the Middle East.

On October 1, the yield on 10-year US Treasury notes hit 5.34%, the highest level in 24 years, rising over 80 basis points in the quarter. French bond yields also reached a 24-year high, nearing 5%, while Japan’s 10-year bond yields neared a 30-year peak of 3.115%. Australia’s central bank raised its key rate to 4.60%, the highest in 15 years, with more tightening expected.

The Federal Reserve signaled a potential pause in rate hikes after New York Fed President John Williams suggested no rush for an October increase. This shifted market expectations from 70% to less than 50% for an October rate hike. Weak economic data, including falling job openings and lower-than-expected inflation, contributed to this shift. However, inflation remains above the Fed’s 2% target.

Geopolitical risks intensified as tensions between the US and Iran escalated, with Washington deploying additional forces to the Middle East. Brent crude prices surged over 4% before easing slightly. Diesel supply concerns grew as China suspended fuel exports, and the US urged Europe to release reserves. Meanwhile, trade tensions eased as China and the US discussed reducing tariffs on $60 billion worth of goods.

Anthropic’s IPO documents revealed revenue growth to $4.6 billion in 2025, but operating losses exceeded $8 billion. Nvidia authorized a record $150 billion share buyback, surpassing Apple’s 2024 buyback. Markets awaited the US employment report for September, with forecasts predicting 90,000 new jobs and an unchanged unemployment rate of 4.1%.
