US stocks ended down on Friday, capping a week in which erratic crude oil prices whipsawed equities, as investors gauged how the war in Iran was affecting the global oil supply.
All three major US stock indexes logged daily and weekly declines.
The small-cap Russell 2000 RUT ended at its lowest close of the year so far.
Crude prices fluctuated before heading higher, even after US President Donald Trump temporarily eased sanctions on Russian oil to assuage supply concerns.
"We've seen volatility in the energy market that rivals any two-week period in cryptocurrency history. So, it's hard to say that it's being driven by fundamentals," said Paul Nolte, senior wealth advisor & market strategist at Murphy & Sylvest in Elmhurst, Illinois.
"It's very much an emotional market, so it really doesn't make sense trying to trade, let alone invest in this market."
Nolte added: "You just sit back and wait for things to unfold and to settle, and that may happen over the course of a couple of weeks."
Front-month WTI crude futures settled at $98.71 per barrel, up 3.11 percent on the day. Brent LCOc1 rose 2.67 percent to $103.14, settling above $100 per barrel for the first time since August 2022.
Trump's vow to hit Iran "very hard over the next week," combined with reports that the conflict had spread to Lebanon, Kuwait, Iraq, the United Arab Emirates, Bahrain and Oman, has dimmed hopes of de-escalation and near-term resolution.
Trump's comments prompted Iran to tighten its grip on the Strait of Hormuz, conduit for one-fifth of the world's oil. On Thursday, the International Energy Agency said the war will cause the largest-ever disruption in global crude supply.
The Commerce Department's sharp downward revision to fourth-quarter GDP growth dominated a deluge of mostly disappointing economic indicators.
The Personal Consumption Expenditures report showed little movement in the US Federal Reserve's preferred inflation gauge, while other data showed weakening demand for durable goods.
Despite softer economic data, the US Federal Reserve was expected to leave its key interest rate unchanged at the conclusion of next week's monetary policy meeting.
With the threat of spiking oil prices further stoking inflation, the odds of a near-term rate cut are dwindling.
"Inflation remains elevated, and with the possibility of energy prices eventually moving into the pipeline, the Fed is likely to stay on hold for a longer period of time,” said Peter Cardillo, chief market economist at Spartan Capital Securities in New York.
