Dow falls 400 points as oil surge lifts Fed rate-hike bets

US stocks opened September lower as renewed US-Iran hostilities pushed crude to multi-month highs and repriced Federal Reserve rate-hike odds.

The Dow Jones Industrial Average fell 0.79 percent, or about 400 points, on Tuesday as investors weighed an oil-driven inflation shock against higher global bond yields. The S&P 500 and Nasdaq Composite also closed lower, extending a cautious start to September trading.

Market-implied odds of a 25-basis-point hike at the next Federal Open Market Committee meeting have climbed to about 40 percent, up from 30 percent a month ago, according to CME FedWatch data.

The 10-year Treasury yield rose about 15 basis points over the past week to its highest level in months, while crude settled up more than $4 a barrel on renewed US-Iran fighting. The stronger dollar added pressure on gold, which slipped toward $4,450 an ounce.

Higher yields raise the discount rate on future earnings, hitting growth and technology stocks hardest, while energy names stand to benefit from the crude rally. Traders now look to the FOMC meeting for guidance on the rate path.

The selloff tracked a cross-asset repricing driven by the Middle East flare-up. Oil's climb to multi-month highs stoked inflation expectations, prompting investors to demand higher yields on long-term Treasuries and strengthening the dollar, which makes dollar-priced assets more expensive for overseas buyers.

Sector rotation favored energy producers as crude rallied, while airlines, transportation and consumer discretionary names face margin compression from higher fuel costs. The advance-decline picture skewed negative across the S&P 500, with the yield move pressuring the longest-duration sectors.

Oil's $4 Jump Resurrects Supply-Disruption Risk

Crude settled up more than $4 a barrel as the latest fighting resurrected Middle East supply-disruption risks, according to market reports. The move reinforced the case for the Fed to maintain a hawkish stance, with inflation still above the central bank's 2 percent target.

For investors, the September open sets up a test of whether the equity market can absorb higher-for-longer rates. Energy stocks may continue to outperform, but the broader index faces headwinds from elevated real yields, which historically cap valuations on growth and technology names. If crude keeps climbing, margin pressure could spread beyond airlines and transport into consumer discretionary, where fuel and input costs feed directly into earnings. The FOMC meeting, where policymakers will signal whether the oil-driven inflation spike forces another hike, is the next catalyst for direction.
