Sept 8 (Reuters) - The benchmark S&P 500 and the blue-chip Dow indexes were on course to open lower on Tuesday as fresh hostilities in the Middle East pushed oil prices to their highest since late July, while markets await inflation data due later this week.
The declines follow a roller-coaster stretch that saw investors rushing to readjust rate-hike expectations after commentary from Federal Reserve Governor Christopher Waller and a stronger-than-expected jobs
report.
The truncated week after the Labor Day holiday will be dominated by the Consumer Price Index report due on Friday and the Producer Price Index reading on Thursday.
Some investors have said inflation readings will hold more weight for the Fed's rate trajectory, given Chair Kevin Warsh's focus on bringing prices down.
"It still seems to be a bit of a wild card out there. Warsh is not as easily readable as his predecessor Jerome Powell was," said Michael Matousek, head trader at U.S. Global Investors. With oil potentially climbing further, market volatility could persist, he added.
Traders now see a 60.6% chance of an increase in interest rates this month, according to the CME FedWatch tool.
At 8:27 a.m. ET, Dow E-minis shed 445 points, or 0.83%, S&P 500 E-minis were down 20.75 points, or 0.27%, and Nasdaq 100 E-minis rose 4.75 points, or 0.02%.
WAR RISKS FRONT AND CENTER
Now in its seventh month, the U.S.-Iran war has remained an overhang on equities. Tensions flared up again in the region, raising the risk of a wider conflict.
Yemen's Tehran-backed Houthis attacked energy facilities and cities in U.S. ally Saudi Arabia on Tuesday, while Israel struck a southern Lebanese town early on Monday. Shipping traffic through the Strait of Hormuz slowed, with Iran threatening on Monday to retaliate for any new U.S. attacks.
Brent crude futures rose 1.64% to $98.59 a barrel, their highest since July 24.
The oil rally is turning the inflation picture "murkier," said Kyle Rodda, senior financial market analyst at Capital.com. "The military activity is maintaining a significant risk premium in energy markets amidst the heightened possibility of deeper and more protracted disruptions to global supply."
Energy stocks were higher in premarket trading, with Marathon Petroleum and Occidental Petroleum climbing 1.78% and 2.02%, respectively.
Elevated yields on risk-free U.S. Treasuries have in recent weeks made it less attractive for investors to take on the added risk of buying stocks.
The yield on the benchmark 10-year Treasury note rose 0.42 basis points to 4.7882% on Tuesday.
Crypto stocks fell as bitcoin retreated from the $80,000 level. Coinbase fell 1.57% while Strategy was down 2.92%.
Chipmakers rose, helped by optimism toward AI. Intel gained 4.54%, while Nvidia inched 0.51% higher.
"History shows that increased speculation and concerns about excess can carry on for some time without a correction materializing," wrote Ben May, director of global macro research at Oxford Economics.
