Trump's Iran War Stance Adds to Market Jitters as Oil Swings 5%

President Trump's mixed signals on Iran—threatening war while claiming to seek peace—are injecting a new layer of volatility into global markets, leaving investors to decipher whether the president is bluffing or preparing for a wider conflict.

President Donald Trump’s oscillating rhetoric on Iran whipsawed global markets Monday, with his threats of a full-scale assault undermining his own administration's claims of progress in peace talks. The contradictory statements sent oil prices on a volatile 5% swing and left equities struggling for direction as traders weighed the rising risk of a wider Middle East conflict against the slim hope for a diplomatic breakthrough.

“The market is hanging on every word, but the words are pointing in opposite directions,” said Fawad Razaqzada, an analyst at Forex.com. “It’s a good first step if a deal is confirmed, but the president’s own threats are making it impossible to price in any sustainable relief.”

The uncertainty was reflected in shaky trading across asset classes. The S&P 500 finished down 0.1% after a day of yo-yoing between gains and losses, while the Dow Jones Industrial Average added a modest 0.3%. Brent crude, the international oil benchmark, surged to a high of $112 a barrel overnight before falling back below $107, a stark illustration of the geopolitical risk premium now embedded in energy prices. The price is still well above the roughly $70 a barrel seen before the war began in late February.

The economic stakes are high, with finance ministers from the Group of 7 nations meeting in Paris to devise a plan to contain the fallout. The war has already dragged on for 80 days, disrupting global trade and fueling inflation fears, with a recent New York Times/Siena poll showing 64 percent of American voters believe the decision to go to war was wrong.

Cease-Fire Hangs by a Thread

Despite Mr. Trump announcing Monday that he had called off a planned attack on Iran at the request of Gulf leaders, he simultaneously warned that a "full, large scale assault" could happen "on a moment's notice." This came just a day after he posted on social media that for Iran, "the Clock is Ticking, and they better get moving, FAST, or there won't be anything left of them."

Tehran, for its part, said it had conveyed a revised set of terms for a peace deal through Pakistani mediators, insisting the talks are focused entirely on ending the war and have not yet touched on nuclear matters—a key U.S. demand. Iranian state media even floated an unconfirmed report that the U.S. had offered to suspend oil sanctions during negotiations, a claim the Trump administration has not verified. The mixed messaging has left allies and investors alike questioning the coherence of the U.S. strategy.

The diplomatic maneuvering is set against a backdrop of continued military action. A drone strike over the weekend, widely blamed on Iran, caused a fire at a nuclear power plant in the United Arab Emirates. Meanwhile, Israel continues to launch strikes in southern Lebanon against the Iran-backed group Hezbollah, despite a tenuous U.S.-brokered cease-fire.

Strait of Hormuz Chokepoint

Central to the conflict is the Strait of Hormuz, a critical waterway through which roughly a fifth of the world's oil passes. While tanker traffic has ticked up slightly from a wartime low, it remains significantly depressed. U.S. Central Command reported that its forces have redirected 85 commercial vessels as part of a blockade on Iranian ports.

Iran has threatened to require permits for internet fiber optic cables passing through the strait and is working with Oman on a "mechanism" to manage traffic, which analysts see as an attempt to create a toll-booth system. The U.S., however, has sought to contain the economic damage from the blockade, with the Treasury extending a sanctions waiver by 30 days to allow Russian oil already at sea to reach vulnerable nations, a move Treasury Secretary Scott Bessent said would "help stabilize the physical crude market."
