Hopes for diplomatic end to Iran war give boost to shares, ease price of oil

S&P 500 rises 0.5% and Dow Jones adds 0.7%, while markets climb more than 1% in London, Paris, and Shanghai, after US floats truce to Tehran

NEW YORK (AP) — Hopes for a possible end to the war with Iran pushed stocks higher on Wall Street on Wednesday, while oil prices eased.

The S&P 500 rose 0.5 percent in its latest flip-flop after the United States delivered a plan to pause the war with Iran. The Dow Jones Industrial Average added 305 points, or 0.7%, and the NASDAQ composite gained 0.8%.

But the moves were shaky, and the S&P 500 briefly came close to erasing all of its jump, which maxed out at 1.2% in the morning. Financial markets have swung sharply since the war began more than three weeks ago, and many of the reversals have come hour to hour as uncertainty continues to dominate about how long the war will last.

Keeping up that uncertainty on Wednesday, Iran’s Foreign Minister Abbas Araghchi said in an interview with Iranian state TV that his government has not engaged in talks to end the war, “and we do not plan on any negotiations.”

Iran also launched more attacks on Israel and Gulf Arab countries, including an assault that sparked a huge fire at Kuwait International Airport, while coming under attack itself. The US military deployed paratroopers and more Marines to the region.

Optimism, though, was nevertheless evident in financial markets worldwide. Stock indexes climbed more than 1% in London, Paris, and Shanghai. Tokyo’s Nikkei 225 leaped 2.9%.

The price for a barrel of Brent crude delivered in June fell 3% to settle at $97.26. Hopes rose that a cooldown in fighting could allow oil and natural gas to flow more freely from the Persian Gulf to customers worldwide. Many oil tankers are currently stuck outside the Strait of Hormuz off Iran’s coast, and the blockage has sent Brent crude’s price to nearly $120 per barrel at times.

In the bond market, Treasury yields also eased. That could help soften the rise in rates for mortgages and other kinds of borrowing since the beginning of the war. That in turn could lessen the pressure on the economy.

The yield on the 10-year Treasury fell to 4.32% from 4.39% late Tuesday, though it remains well above its 3.97% level from just before the war.

Even gold, which has been one of the investment world’s worst losers through the war, rose. It climbed 3.4% to settle at $4,552.30 per ounce.

Gold’s price had briefly gotten near $5,400 early this month. That was before Treasury yields rushed higher on worries that high oil prices would drive inflation upward and prevent the Federal Reserve from cutting interest rates. When bonds are paying more in interest, they make gold, which pays its investors nothing, less attractive in comparison.

All told, the S&P 500 rose 35.53 points to 6,591.90. The Dow Jones Industrial Average gained 305.43 to 46,429.49, and the NASDAQ composite climbed 167.93 to 21,929.83.
