Wall Street Finishes Nearly Flat as Oil and Bond Yields Keep Investors on Edge

Wall Street ended a volatile Thursday almost exactly where it started. The S&P 500 finished near flat after opening sharply lower, while the Dow Jones Industrial Average fell about 0.3% and the Nasdaq Composite was little changed. The session began under pressure as Middle East uncertainty pushed oil prices and Treasury yields higher, but stocks recovered from their lows after reports that U.S. and Iranian negotiators were exploring a phased plan that could reopen the Strait of Hormuz and reduce some of the economic pressure tied to the conflict.

The market's biggest immediate problem remains the combination of expensive energy and high interest rates. Rising oil prices can keep inflation elevated, while higher Treasury yields make borrowing more costly and reduce the relative appeal of richly valued growth stocks. Federal Reserve Governor John Williams said another rate increase this year would be reasonable, reinforcing the idea that investors may have to contend with tighter financial conditions for longer. That backdrop weighed on technology and semiconductor shares during the session, with several AI-linked names trading lower earlier in the day.

Investors are also watching the intersection of geopolitics and inflation more closely than usual. The Strait of Hormuz is one of the world's most important energy corridors, so any progress toward reopening it could quickly lower the risk premium embedded in crude oil prices. That would matter for the stock market because lower energy costs could ease pressure on inflation expectations and bond yields. Thursday's rebound from the session lows showed how sensitive equities have become to any sign that the conflict may de-escalate.

The broader market picture is still mixed rather than clearly bullish or bearish. Earlier in the week, AI optimism and falling oil prices helped push the Nasdaq to record territory, but the market has also shown how quickly gains can reverse when oil and yields rise. For investors, the next major drivers are likely to be energy prices, Treasury yields, Federal Reserve guidance and any concrete progress in U.S.-Iran negotiations. Until those pressures ease, the market may remain vulnerable to sharp intraday swings even if the major indexes continue to hold near record levels.
