Stocks Fall as Oil Surges After U.S. Strikes Iran, 10-Year Yield Hits Highest Since January

Hyperdash News|09/01/2026 20:30 UTCMacro

U.S. stocks fell to start September as a jump in Crude oil stoked inflation worries and drove Treasury yields to their highest since January. The S&P 500 fell -0.71% to 7,631 after U.S. strikes on Iran in the Strait of Hormuz.

Scoreboard

• S&P 500 7,631 (-0.71%)
• Euro Stoxx 50 6,369 (-0.80%)
• Nikkei 225 66,215 (-0.15%)
• Gold 4,376 (-2.37%)

• Bitcoin 77,266 (-2.10%)
• VIX 16.40 (+9.92%)
• DE 10Y 3.369% (-1bp)

The selloff followed U.S. military strikes on Iran in the Strait of Hormuz and President Trump's threat of further action should Tehran retaliate. WTI jumped +5.68% to 90.63 and Brent climbed +5.13% to 95.13, both settling near six-week highs. The oil surge lifted the US 10Y yield +3bp to 4.792%, its highest since January, as global bond yields pushed toward multi-decade highs. Fed Governor Michael Barr said he would support a rate hike if inflation fails to ease. The VIX jumped +9.92% to 16.40 as stocks slid.

Key headlines

• Nasdaq Tumbles 1% to Start September
• Dow Falls for Third Day as Stocks Decline, Oil Jumps, 10-Year Yield Hits 4.8%
• Global Oil Futures Settle at Nearly Six-Week High Amid Mideast Tensions
• 10-year yield hits highest since January 2025 as higher oil prices stoke inflation worries

The takeaway

The move in oil cut two ways against equities: it lifted energy costs and, by stoking inflation worries, pushed the US 10Y yield to its highest since January. That combination, higher input prices and higher discount rates, left equities with little cover, and the VIX jumped +9.92%.

Treasury Secretary Scott Bessent touted the bond market as yields spiked, while Barr's remarks kept a further rate hike on the table. Ahead lie any Iranian response to the U.S. strikes, the path of Crude, and upcoming inflation data. The DXY edged up +0.27% to 99.6920.
