Oil prices have spiked and US stocks have fallen sharply as the countdown continues towards President Donald Trump's latest deadline for Iran to open the Strait of Hormuz. Trump has threatened to destroy Iranian power plants and bridges if the demands are not met by 8pm Eastern time, raising fears of further conflict in the region. The uncertainty has roiled financial markets, with the S&P 500 dropping 1% and the Dow Jones Industrial Average down nearly 400 points.

Why it matters

The ongoing tensions between the US and Iran have already disrupted global oil production and transportation, sending crude prices soaring. A prolonged conflict or further escalation could lead to a sustained period of high energy costs, fueling inflation and potentially tipping the global economy into recession. Investors are closely watching for any signs of a diplomatic breakthrough or de-escalation to ease the market volatility.

The details

Oil prices have jumped 3.8% to $116.72 per barrel for US crude and 0.7% to $110.58 for Brent crude, as the war has snarled production and transportation of crude in the Persian Gulf. Much of that oil exits the region through the Strait of Hormuz, which Iran has blocked to its enemies. The sharp rise in energy costs has already started to impact businesses and consumers, with the national average price for a gallon of regular gasoline jumping to $4.14, up from less than $3 before the conflict began.

  • President Trump set an 8pm Eastern time deadline on April 7, 2026 for Iran to open the Strait of Hormuz.
  • The US and Israel launched attacks to begin the war in late February 2026.

What they’re saying

“A 'whole civilization will die tonight, never to be brought back again' if Iran does not meet his deadline at 8 p.m. Eastern time to open the Strait of Hormuz.”

— President Donald Trump

“Investors are likely to remain on edge and markets unable to establish trends, probably until there is a clear outcome later this evening: a deal, the U.S./Israeli strikes intensify, or Iran's retaliation becomes escalatory instead of proportional.”

— Paul Christopher, Head of Global Investment Strategy, Wells Fargo Investment Institute

What’s next

The world will be watching closely to see if President Trump follows through on his threat to destroy Iranian infrastructure if the Strait of Hormuz is not opened by the 8pm Eastern deadline. Any further escalation or retaliation from Iran could send shockwaves through global financial markets and the broader economy.

The takeaway

The ongoing tensions between the US and Iran have created significant uncertainty and volatility in global financial markets, with the prospect of a prolonged conflict threatening to drive up energy costs and fuel inflation worldwide. Investors are hoping for a diplomatic resolution, but the risk of miscalculation and further escalation remains high.
