The move followed Trump’s rejection of an Iranian proposal aimed at reopening the Strait of Hormuz and restarting negotiations between Washington and Tehran.
The Strait is one of the most consequential shipping passages on Earth. Disruptions there can quickly reverberate through oil markets, transportation networks and ultimately the prices paid by ordinary consumers.
Trump made it clear over the weekend that Tehran’s proposed terms weren’t going to get an automatic green light from his administration.
“I like making a deal, too. But, I’m not – that deal would not be acceptable,” he told reporters as he was departing the White House. “They want to make a deal where they open the strait immediately because they’re losing so badly.”
Iran’s proposal called for steps from Washington before Tehran would fully reopen the critical waterway.
Among Iran’s demands were reduced U.S. military pressure, an easing of restrictions affecting Iranian oil exports and changes involving the blockade of Iranian ports.
Trump wasn’t buying it.
And energy traders immediately began pricing in the possibility that the confrontation could drag on.
That’s potentially bad news for American drivers.
Gasoline and diesel prices have already been squeezed by the conflict, and prolonged instability could keep pressure on fuel supplies as the Northern Hemisphere approaches the colder months.
The consequences don’t necessarily stop at the gas station.
When diesel and gasoline become more expensive, trucking companies, airlines, manufacturers and shipping operations face higher costs.
Those expenses can eventually work their way through the economy, showing up in everything from grocery bills to consumer products delivered by truck.
Investors were also watching the inflation implications.
If an energy shock keeps inflation elevated, the Federal Reserve could face a more complicated path on interest rates. Bond markets reflected some of that concern Monday as Treasury yields moved higher.
Nic Puckrin, cross-asset analyst and founder of Coin Bureau, warned that several potentially explosive economic pressures are now converging.
“Refined-product supply is being exhausted, the Strategic Petroleum Reserve is at its lowest level since 1982, and the political situation is getting more fraught as we approach the midterms,” he wrote. “Meanwhile, cold weather in the Northern Hemisphere is just around the corner.
“Add to that the ocean of debt the US is drowning in, and yields above 5% start to look like the new normal.”
The White House is also examining additional measures aimed at protecting domestic fuel supplies.
Trump has said he is “very seriously” considering restrictions on diesel exports as his administration looks for ways to prevent Americans from absorbing even more of the economic fallout from the conflict.
But Tehran isn’t exactly lowering the temperature.
Iranian Foreign Minister Abbas Araghchi delivered an extraordinary warning during an appearance on NBC’s “Meet the Press,” declaring that Iran is prepared for another major confrontation.
“We stand firm in the face of any aggression against us, even when it comes to a doomsday war,” he told NBC’s “Meet the Press” in an interview aired Sunday. “At the same time, we are ready for diplomacy.”
Araghchi nevertheless insisted that negotiations remain possible.
He called Iran’s cease-fire proposal a “very reasonable plan on the table.”
That leaves Washington and Tehran in a precarious position: Both sides continue talking about diplomacy while simultaneously preparing for the possibility that fighting could intensify again.
And the longer that uncertainty continues, the greater the risk that energy markets remain under pressure.
Europe could find itself in an especially difficult position.
The continent depends heavily on imported energy, making prolonged disruptions particularly painful as colder weather approaches.
Stephen Coltman, head of macro at 21shares, warned that the approaching winter could magnify the problem.
“Europe is particularly exposed heading into winter as a net importer of both US diesel and Qatari LNG,” Coltman wrote in a note Monday. “Gas inventories in Europe are much lower than seasonal norms and demand is set to rise rapidly in the weeks ahead.”
For Trump, the stakes extend far beyond another round of negotiations with Tehran.
The president is trying to maintain pressure on Iran without allowing the resulting energy shock to punish American consumers indefinitely.
For Tehran, control over access through the Strait of Hormuz remains one of its biggest sources of leverage.
And for everyone else, Monday’s oil surge was another reminder of just how quickly events thousands of miles away can show up in an American family’s monthly budget.
With Brent back above $107, winter approaching and neither Washington nor Tehran showing signs of backing down from their central demands, the world’s energy markets are once again bracing for what comes next.
