The White House said Trump will deliver a public address Wednesday evening on the Iran war.

Trump’s remarks came after he told U.S. allies to “go get your own oil” and blamed them for refusing to be more involved in its war effort. Significant maritime traffic disruption at the Strait of Hormuz, where roughly a fifth of the world’s oil typically passes through, has sent energy prices surging and is fueling global inflation.

Oil prices fell and were briefly down 4% to below $100 a barrel on Wednesday, though the losses later narrowed. Brent crude, the international standard, was down 1% at $102.98 per barrel. Benchmark U.S. crude dropped 1.1% to $100.31.

As the Iran war rattles global energy markets, on Tuesday, U.S. gas prices surged past an average of $4 a gallon, the first time since 2022.

“De-escalation hopes have given markets a lift, but we think the effects of the war would, in many cases, persist even if the war did end soon,” wrote Thomas Mathews, head of markets, Asia Pacific at Capital Economics in a research note Wednesday.

“It’s worth thinking through how markets might fare if the war were to end ‘very soon,'” he wrote. “Do markets have further to recover if sentiment continues to improve? The answer is almost certainly yes.”

Wall Street advanced on Tuesday. The S&P 500 jumped 2.9% for its largest gain since May to 6,528.52. The Dow Jones Industrial Average surged 2.5% to 46,341.51, and the Nasdaq composite leaped 3.8% to 21,590.63.
