Fill up your truck in California right now, and you're paying $6.92 a gallon for diesel.
That's up from $5.10 before the Iran war started.
And here's the part that should worry you even if you've never set foot in California: that price is about to show up in your grocery bill too.
Stay with me — this one connects more dots than it seems.
California isn't just another state at the pump.
It's home to the San Pedro Bay port complex — the busiest containership hub in the country.
👉 Nearly one-third of all U.S. imports and exports pass through it.
So before that phone case, that couch, that box of cereal reaches a shelf in Ohio, it first gets loaded onto a truck or train.
And that truck runs on California diesel.
At California prices.
Most war coverage obsesses over crude oil prices.
But the tighter, scarier market is diesel — the actual workhorse fuel that moves freight across the U.S.
Here's why it's squeezed from every direction:
Add it up, and Lipow Oil Associates estimates the world is now short about 8% of global diesel demand.
Eight percent doesn't sound huge. In fuel markets, it's a earthquake.
That's roughly what ExxonMobil CEO Darren Woods told CNBC.
Even once the Strait reopens, he said, refiners still have to absorb the Russian capacity that's already gone.
Meaning: don't expect a quick snapback.
And California isn't even the extreme outlier anymore — some reports this year have shown parts of the state pushing past $7, even $8 a gallon at various points, blowing past the old record of $7.01 set back during the 2022 Ukraine energy shock.
Think about that.
A war half a world away, in Iran, is resetting fuel-price records that were set by a different war, in a different region, four years ago.
JPMorgan analysts put it bluntly in a note to clients:
"A meaningful share of America's supply chain pays West Coast fuel prices."
Those prices don't stay in California.
They flow straight into:
So a shopper in Texas or New York, who's never heard of the San Pedro Bay port, still ends up quietly subsidizing this diesel spike every time they check out.
The average U.S. diesel price sits at $5.36.
California is running nearly $1.60 above that.
That gap is the whole story in one number — a state that handles a third of the nation's trade, paying the nation's highest fuel prices, with a war overseas making both numbers worse.
Six months into the Iran conflict, the front line isn't just in the Gulf.
It's on the 405 freeway, in a truck stuck in traffic, burning through a tank that costs almost two dollars more than it did before the war began.
That's all for now!
