Markets Surge and Oil Tumbles as Trump Hits Pause on Iran Strikes

A single social media post from President Donald Trump was enough to send financial markets into a sharp reversal on Monday, erasing days of anxiety and triggering one of the more dramatic single-day swings seen in recent weeks. The announcement that the United States would hold off on further strikes against Iranian energy infrastructure, pending the outcome of diplomatic discussions, gave investors exactly the signal they had been waiting for.

The Dow Jones Industrial Average closed up more than 630 points, a gain of roughly 1.4%. The S&P 500 added 1.15% and the Nasdaq climbed by a similar margin. Both indexes had briefly surged past 2% before pulling back as the initial enthusiasm was tempered by conflicting signals from the region. The Nasdaq had closed Friday teetering on the edge of correction territory, just barely short of a 10% decline from its recent peak, making Monday’s rebound particularly welcome for investors who had watched the index slide through the previous week.

Oil Posts Its Biggest Drop in Weeks

The more dramatic movement came in the energy markets. Brent crude, the globally referenced oil benchmark, fell nearly 11% to settle below the psychologically significant threshold of $100 per barrel for the first time since mid-March. American crude followed a similar trajectory, dropping just over 10% to its lowest settlement price in the same period. The declines represented the largest single-day fall in oil prices since earlier in the month, when Trump had last suggested the Iran conflict might be nearing its end.

The reversal came after prices had reached their highest point since the summer of 2022 just days earlier. Iran’s effective closure of the Strait of Hormuz, the narrow waterway that handles roughly a fifth of global oil supply, has been the primary driver of that surge since military operations began at the end of February. Trump’s weekend ultimatum, threatening to strike Iranian power plants unless the blockade was lifted, had sent markets bracing for further escalation. Monday’s announcement moved in the opposite direction.

Gasoline and diesel futures in the United States also dropped sharply, falling approximately 9.5% and 10% respectively. The relief, however welcome, needs to be placed in context. Both fuels remain roughly 70 to 80% more expensive than they were at the start of the year, and the declines of a single day do not come close to reversing the cumulative impact of weeks of elevated prices.

Americans Are Already Feeling the Consequences

For ordinary drivers, the pain at the pump has been accumulating steadily. US gasoline prices rose for the 23rd consecutive day on Monday, reaching an average of $3.96 per gallon according to figures from AAA. That marks the highest average price since the summer of 2022 and represents a increase of more than $1 per gallon over the course of a single month, a pace of increase that exceeds the spikes seen following Hurricane Katrina in 2005 and the Russian invasion of Ukraine in 2022.

That latter episode eventually pushed prices to a record high above $5 per gallon before they receded. Whether the current situation follows a similar arc depends heavily on how events in the Middle East unfold.

Complicating Monday’s market optimism was a clear disconnect between Washington and Tehran over what is actually happening diplomatically. Iranian officials flatly rejected Trump’s characterization of meaningful progress in negotiations, while Israeli military operations in Tehran continued regardless. Analysts cautioned that any sustained market recovery would require concrete developments on the ground rather than social media announcements, and that the coming days would be critical in determining whether Monday’s rally had genuine legs or was simply a relief bounce in a market still driven almost entirely by geopolitical headlines.
