Wall Street and Global Stock Market Performance

NEW YORK, April 20 (Reuters) - Wall Street pulled back from record highs on Monday and oil prices spiked as increasing tensions over the crucial Strait of Hormuz raised concerns that the fragile U.S.-Iran ceasefire might not hold.

All three major U.S. stock indexes lost ground, and the Nasdaq closed the book on a 13-day winning streak, its longest since January 1992.

The equity-market losses were shallow, held in check by hopes that a deal will eventually be reached, and ongoing optimism over solid first-quarter corporate earnings, and other markets, such as the dollar and U.S. Treasuries, were also subdued.

Investor Sentiment and Commentary

"We're not seeing a lot of selling pressure develop because the action that the market saw last week highlighted the importance of staying invested," said Robert Pavlik, senior portfolio manager at Dakota Wealth in Fairfield, Connecticut. "The opportunity potentially missed by being out of the market is probably keeping a lid on the losses today."

"Everybody knows that the war could change on a dime," Pavlik added.

US-Iran Ceasefire Developments

The uneasy ceasefire between the United States and Iran frayed after the U.S. announced it had seized an Iranian cargo ship, prompting vows of retaliation from Iran, which over the weekend said it would not participate in a second round of negotiations. A senior Iranian official later told Reuters that the country is considering sending representatives to talks that are expected to take place in Islamabad.

Impact on Oil and Commodity Prices

Those fears reignited a rally in crude oil prices with traffic through the Strait of Hormuz still largely halted. U.S. crude rose 6.9% to settle at $89.61 per barrel, while Brent settled at $95.48 per barrel, up 5.6%.

Key Takeaways

  • Failed U.S.–Iran negotiations and seizure of an Iranian‑flagged cargo ship elevated geopolitical risk, denting equity sentiment.
  • Markets remain highly reactive to the volatile interplay of ceasefire developments, navigation status in Hormuz, and diplomatic signals.
