Oil Rockets Past $110 and Gas Hits $4 a Gallon After Trump's Iran Speech

Published Apr 2, 2026

A pressure gauge labeled "Crude Oil" is shown at an oil refinery, with a digital sign displaying "$4.08/GAL National Avg. Unleaded," flames burning in the background—a stark illustration of rising oil prices.
Summary:
  • U.S. crude oil jumped 12% to above $112 a barrel after Trump's Wednesday speech offered no path to a ceasefire with Iran.
  • The national average for a gallon of unleaded gas reached $4.08 - up from $2.98 before the war started.
  • Asian stock markets sold off hard, with South Korea's KOSPI dropping 4.2% and regional indexes falling across the board.

A gallon of gas costs $1.10 more today than it did before the first bombs dropped. Diesel cracked $5.51 a gallon.

That's the price of a war with no end date.

Trump Promised Speed. Markets Wanted a Plan.

President Trump went on national TV Wednesday night and said the fighting with Iran would be over "shortly." In the same breath, he promised additional strikes stretching out another two to three weeks.

What he didn't offer was a road map. No ceasefire framework. No plan for unlocking the Strait of Hormuz - the chokepoint where about 20% of the world's oil moves through.

His answer on the strait: it would "open up naturally."

Crude started running higher the moment Trump started talking and kept going through Thursday. By the afternoon, U.S. crude was up 12% and trading north of $112.

Brent crude - the price the rest of the world watches - tacked on 8% to push past $109.

One bright spot did surface midday. Iran's deputy foreign minister mentioned a possible "new navigation regime" for the strait after fighting wraps up.

That pushed U.S. stocks off their lows - the S&P 500 trimmed its drop to just 0.3% by early afternoon. Oil barely flinched at the comment.

The Damage Is Spreading

This isn't just an oil story anymore. It's showing up in borrowing costs.

A 30-year fixed mortgage is running 6.41% right now. The day before bombs started falling, that number was 5.99%.

Bond interest rates - what investors call yields - have climbed from around 3.96% in late February to roughly 4.30%. When yields rise, everything from car loans to credit cards gets more expensive.

Analysts at Bank of America put out a note saying the Fed's go-to inflation number - the PCE index - is on track to hit nearly 4% before summer. That reading was 2.8% back in January.

In Europe, prices jumped even faster. March inflation came in at 2.5%, way up from the 1.9% reading a month earlier.

What to Watch

U.S. markets are dark Friday for Good Friday - meaning Thursday was the last session before a three-day weekend. During stretches like this, investors tend to lighten up. Nobody wants to sit on a position while the ground shifts overseas.

Britain pulled 35 countries onto a call Thursday to talk about getting the strait back open. The U.S. wasn't on it.

The war is still setting the price of everything.

Common Investing Mistakes: Why a Stock Grade Is One Tool, Not the Whole Toolkit
  • The Briefs Score shows growth, income, and wealth preservation investors how well a stock fits their goal, with a separate letter grade for each one.

  • Research works best as one input in a process you own. The grade shows how a stock stacks up. You supply the goal, the timeline, and the rules for being wrong.

  • An asset puts money in your pocket and a liability takes money out, and the wealthy buy assets first, then let the assets pay for the fun stuff.
  • Before you buy anything, ask one question: does this put money in my pocket, or take money out of my pocket? Then you need a plan for the money you keep.

How to Build Your First $2,000 Emergency Fund and Wipe Out Every Debt Over 10%
