NEW YORK — Oil prices climbed Monday following the latest rise of tensions between the United States and Iran, but the moves were more modest than they were earlier in the war. U.S. stocks, meanwhile, gave back a bit of their record-breaking rally.

The S&P 500 slipped 0.2% from its all-time high for just its second drop in 14 days after the United States seized an Iranian-flagged cargo vessel that it said had tried to evade its blockade of Iranian ports. The Dow Jones Industrial Average dipped 4 points, or less than 0.1%, and the Nasdaq composite fell 0.3%.

The price for a barrel of Brent crude oil, the international standard, climbed 5.6% to settle at $95.48 on worries that Iran could keep petroleum pent up in the Persian Gulf if it continues to block tankers from exiting the Strait of Hormuz.

It’s a turnaround from the prior trading day on Wall Street, when stocks soared and oil prices tumbled after Iran said Friday it was reopening the strait to commercial traffic. That enthusiasm vanished quickly after Iran closed the strait again Saturday following the U.S. decision to press ahead with its blockade of Iranian ports.

The next big deadline is looming on Tuesday night at 8 p.m. Eastern time, which is early Wednesday Tehran time, when a ceasefire agreement between the United States and Iran is scheduled to expire.
