U.S. stocks fell on September 1 while global bond markets sold off sharply, driven by surging oil prices after renewed U.S.-Iran tensions and a climb in Treasury yields that pushed the 10-year toward 4.80%.
The Dow, S&P 500, and Nasdaq all declined, with technology stocks leading losses. Energy shares outperformed, but the broader market was weighed down by fears that higher crude costs could feed into consumer inflation just as the Federal Reserve is considering another rate hike.
Global yields rose across the board. Japan's 10-year yield reached 3%, its highest in roughly three decades, while the United Kingdom and Germany also experienced multi-year highs. The synchronized move higher in government borrowing costs added stress to equity valuations, especially for growth-dependent sectors.
Traders now assign roughly a 68% probability to a 25-basis-point Fed hike in September, up from about 40% a week earlier. That repricing is hurting mortgage-sensitive industries and raising the discount rate applied to long-duration technology stocks.
With crude elevated, yields higher, and seasonal weakness in September already in market lore, the start of the month has reinforced rather than relieved investor caution. The path forward depends heavily on whether inflation data and Fed communications reinforce or contradict the current hawkish tilt.
