President Donald Trump vowed to retain military assets in the Middle East until a peace deal was reached with Iran and warned ‌of a major escalation ⁠if ⁠it failed to comply, while Israel bombed more targets in Lebanon as Tehran warned there would be no deal unless Tel Aviv ceases bombing the country.

Few signs ​of traffic moving through the Strait of Hormuz heightened uncertainty around energy shipments, leading to a rebound in oil prices, though they remained below $100 a ​barrel.

The S&P 500 energy sector added 1.3% and utilities stocks were the biggest percentage gainers, up 1.6%.

"Moving from the brink of a continued escalation in Iran to a more diplomatic approach has calmed markets down from some perspective," said Charlie Ripley, senior investment ​strategist for Allianz Investment Management.

The S&P 500 and the Nasdaq posted their biggest one-day jumps in over a week on Wednesday, as global markets cheered the two-week ceasefire, while the Dow marked its steepest rise in a year.

Meanwhile, data showed U.S. inflation increased as expected in February and likely rose further in March amid the Iran war, while economic growth slowed more than previously estimated in the fourth quarter.

"(This doesn't) really change the narrative from a Fed perspective in ‌that we have elevated inflation pressures, so that is going to keep them on hold for the time being," said Ripley.

Money market participants are expecting only about 30% chances of a 25 basis-point interest rate cut by end-2026, compared with a 56% chance a day ago, per LSEG-compiled data.
