Oil prices fell and stocks rose on Monday after the United States and Iran reached an agreement that President Trump said would reopen the Strait of Hormuz.

Mr. Trump’s social media post capped weeks of fraught negotiations between the countries that, at times, seemed to make little progress. A key mediator in the peace talks, Pakistan's prime minister, said the agreement covered Lebanon and that a signing ceremony was scheduled for Friday in Switzerland.

The specifics of the agreement remained opaque, but restoring shipping through the Strait of Hormuz has been among Mr. Trump’s top priorities.

“I hereby fully authorize the toll-free opening of the Strait of Hormuz, and, simultaneously herewith, authorize the immediate removal of the United States Naval blockade,” Mr. Trump posted online. “Ships of the World, start your engines. Let the oil flow!”

The removal of the U.S. blockade — which was intended to stop the flow of Iranian oil — is just one piece of restoring shipping through the narrow waterway on Iran’s southern coast. Iran would also need to relinquish its control over ship traffic. The country’s deputy foreign minister, who confirmed the deal, said Iran’s commitments under the accord would begin on Friday.

Oil prices dropped.

· The price of Brent crude, the global benchmark for oil, fell nearly 5 percent to around $83 a barrel, extending last week’s losses on the hope that a deal would restore shipping through the strait.

· West Texas Intermediate crude, the U.S. benchmark, experienced similar losses, trading at around $81 a barrel on Monday.

· Investors and analysts are focused on shipping in the Strait of Hormuz, the narrow waterway between Iran and Oman and a vital trading route for oil and natural gas that normally carries as much as one-fifth of the world’s oil supply.

Stocks surge.

· Futures on the S&P 500 pointed to a solid 1.2 percent rise when stocks resume trading in the United States on Monday.

· Stocks in Asia, where countries import vast quantities of oil and gas, shot higher. Benchmark stock indexes in South Korea and Japan jumped about 5 percent, while shares in Taiwan rose about 3 percent.

Gasoline prices dipped.

· Gas prices fell slightly on Sunday, to a national average of $4.07 a gallon, according to the AAA motor club. Still, gas prices for drivers are up about 37 percent since the war began.

· Gas prices don’t move in lock step with crude, usually trailing increases or drops by a few days.

· The average price of diesel fell slightly to $5.22 on Sunday, up about 39 percent since the start of the war.
