You’ve likely enjoyed the recent stretch of sub-$3 gas at your local station. It felt like a rare win for the wallet. But that era is ending fast. Over the weekend, the U.S. and Israel launched strikes against Iran, and the global oil market did exactly what you’d expect. It panicked.
Oil futures surged immediately. West Texas Intermediate (WTI) and Brent crude both spiked by more than 5% within hours of the news. If you’re wondering why a conflict thousands of miles away matters when you’re filling up your Ford F-150 in Florida or Ohio, the answer is simple. Oil is a global commodity. When a major producer like Iran gets hit, or when the world's most vital shipping lane is threatened, every driver pays the "war premium."
Experts are already warning that the national average, which sat around $2.99 last week, could soon blow past $3.50. Some analysts at JPMorgan and Citi are even whispering about $120 a barrel oil if things spiral. That would put us back in $4 or $5 per gallon territory.
The choke point that controls your wallet
The biggest threat isn't just the missiles. It’s the water. The Strait of Hormuz is a narrow strip of sea between Oman and Iran. It’s the only way out for about 20% of the world's total petroleum liquids. We’re talking 20 million barrels of oil every single day.
Iran’s Revolutionary Guard has already warned shippers to stay away. That’s a de facto blockade. When 20 million barrels of oil can’t reach the market, prices don't just rise. They "gap" upward. It’s a violent shift in the supply-demand balance.
While the U.S. doesn't buy much oil directly from Iran anymore, we live in a connected world. If China and India can't get their Iranian or Middle Eastern crude, they’ll bid up the price of oil everywhere else. You’re competing for the same barrel of oil as a refinery in Shanghai.
- 84% of the oil through the Strait goes to Asia.
- 20% of global LNG (Liquified Natural Gas) also passes through here.
- 15 million barrels per day are currently stalled as vessels drop anchor to avoid the crossfire.
Why gas prices move slower than oil
You’ll see the "Oil Up 8%" headline tonight. You might not see the 20-cent jump at the pump until Wednesday. Gas stations usually lag behind the futures market by a few days. They’re selling the inventory they bought last week at lower prices.
But don't get comfortable.
Patrick de Haan, the head of analysis at GasBuddy, points out that while the initial hike might be a nickel or a dime, the "real" adjustment happens within a week. By Friday, you could be looking at a 30-cent increase in many states. If you live in high-tax markets like California or Washington, that jump could be closer to 80 cents.
Diesel is even more sensitive. Truckers are going to see daily price hikes. Since almost everything you buy is delivered by a truck, this war isn't just going to make your commute more expensive. It’s going to make your groceries more expensive, too.
The summer blend double whammy
The timing of this conflict is brutal. March is typically when refineries begin the "spring flip." They switch from producing winter-grade gasoline to summer-blend gasoline.
Summer gas is more expensive to make. It uses costlier additives to prevent evaporation during hot weather. This switch usually adds 10 to 15 cents to the price per gallon regardless of what’s happening in the Middle East. Throw a war on top of that seasonal hike, and you have a recipe for a price shock that could last all the way through Labor Day.
Can the Strategic Petroleum Reserve save us?
The U.S. government has one major lever to pull: the Strategic Petroleum Reserve (SPR). As of late February 2026, the SPR holds about 415 million barrels. That sounds like a lot until you realize it’s nowhere near its full capacity of over 700 million.
President Trump may authorize a massive release to stabilize prices, especially with midterm elections looming. A release can suppress prices by $10 or $15 a barrel temporarily. But it’s a band-aid. It doesn't fix the fact that 20% of the world's oil is stuck behind a combat zone.
We’re also producing record amounts of domestic oil—about 13.6 million barrels per day. That helps, but it doesn't insulate us from global price spikes. We still export our light sweet crude and import the heavy stuff our refineries were built to handle. We’re part of the global machine, like it or not.
What you should do right now
Stop waiting for the "perfect" time to fill up. If your tank is half empty, top it off today. The prices you see on the sign right now are likely the lowest you’ll see for the next several months.
Keep an eye on the Brent Crude price index. If it stays above $80, expect $3.50 gas to become the new normal. If it hits $100, prepare for $4.00.
Don't panic-buy gas in containers. That just creates artificial shortages and drives prices up faster for everyone. Just stay informed and adjust your budget now. The "peace dividend" of low energy costs is officially over. Check your local gas apps tonight before the morning rush increases hit the registers. Don't wait until the weekend. Prices will be higher by then.
Keep your tires inflated and combine your errands. It sounds like old-school advice, but when gas jumps 50 cents in a month, every mile counts. Watch the news out of the Persian Gulf. If the Strait of Hormuz stays closed for more than a week, we aren't just looking at a price spike; we're looking at a global energy crisis.
