U.S. stocks closed lower on Sept. 10 as surging crude prices, rising Treasury yields and renewed inflation concerns pressured risk assets. October West Texas Intermediate (WTI) crude settled at $102.48 a barrel, up $6.43, or 6.69%, after reaching $103.06 intraday, while November Brent rose 6.34% to $107.63; both contracts recorded their highest closes since May 19. Brent had gained about 30% since the start of the second half and moved above $100 as the continuing U.S.-Iran conflict, attacks on tankers and Yemen's Iran-backed Houthi seizure of Mocha raised concerns about shipments through the Strait of Hormuz, Bab el-Mandeb and the Suez Canal. IBK Investment & Securities said tensions could persist through the U.S. midterm elections and that clashes could broaden to involve the United States and China. The Dow Jones Industrial Average fell 0.60% to 52,064.10, the S&P 500 declined 0.58% to 7,591.70 and the Nasdaq Composite lost 0.65% to 26,081.72. The 10-year Treasury yield reached 4.97% intraday, near the October 2023 peak of 4.99%, while the 30-year yield closed at 5.360%, its highest close since June 2004, and the two-year yield rose to 4.548%. August producer prices increased 0.4% from July and 5.4% year over year, above the 5.3% forecast, while CME FedWatch placed the probability of a September rate hike at about 60%, reviving concern that tighter policy could weigh on equities even if the Federal Reserve holds rates at the upcoming meeting.
