Gas Prices Are Just the Beginning: How the Iran War Could Raise Costs Across the U.S. Economy

Rising gasoline prices are often the most visible sign of geopolitical conflict for American consumers. But economists warn that the economic impact of the recent U.S. and Israeli strikes on Iran could extend far beyond the pump. As oil prices climb, transportation costs are rising across global supply chains—setting the stage for higher prices on a wide range of goods purchased by U.S. households.

Rising Oil Prices Ripple Through the Economy

Since the military strikes targeting Iran, oil and gasoline prices have surged, drawing the attention of financial markets and consumers alike. However, energy prices represent only the first wave of economic effects.

Higher oil prices directly raise the cost of transporting goods worldwide. Cargo ships, freight trains, trucking fleets, and cargo planes all depend heavily on fuel. When oil prices spike, shipping costs quickly follow.

That means the price of moving everything from groceries to electronics across the United States could soon increase—especially if the conflict continues.

Brian Bethune, an economics professor at Boston College, said businesses may struggle to absorb the rising costs because many are already dealing with financial pressure from tariffs imposed over the past year.

“If we see the persistence of these higher oil prices for a period of time, then you’re going to see a persistent cost shock,” Bethune said.

Fuel Surcharges Are Already Taking Effect

The impact of higher fuel prices is already showing up in shipping fees.

Many freight companies adjust their pricing through fuel surcharges tied directly to diesel prices. For example, FedEx Ground and residential deliveries add a 21.5% surcharge once diesel reaches at least $3.55 per gallon.

According to the U.S. Energy Information Administration, diesel prices hit $4.86 per gallon as of March 9—nearly $1 higher than the week before.

That jump triggers a 24.75% fuel surcharge for the upcoming week.

Similar pricing systems are used across major freight sectors including trucking, rail shipping, air cargo, and ocean freight. As fuel prices rise, these surcharges quickly ripple through supply chains.

Grocery Stores May Be the First Place Consumers Notice

For many Americans, the first noticeable price increases may appear at the grocery store.

Deborah Weinswig, CEO and founder of retail research firm Coresight Research, says food products—especially perishable ones—are particularly sensitive to rising transportation costs.

Fresh produce, meat, and dairy products require constant refrigeration and rapid shipping. Because these items cannot be stored long-term, retailers have less ability to stockpile them ahead of price increases.

As a result, grocery store shelves may reflect higher transportation costs sooner than other sectors.

Outside of supermarkets, price increases could take longer to appear.

Over the past year, tariffs implemented under President Donald Trump prompted many companies to build up inventory before new duties took effect. That means some retailers currently have large stockpiles of products, delaying the impact of rising shipping costs.

Companies May Turn to “Shrinkflation”

Businesses may also look for creative ways to manage rising expenses.

A similar situation unfolded in 2022 after Russia’s invasion of Ukraine sent global oil prices sharply higher, intensifying already high inflation in the United States.

At the time, many companies turned to a strategy known as “shrinkflation”—reducing product sizes while keeping prices the same. Consumers ended up paying more per ounce or unit, even if the price tag didn’t change.

But with American households already cutting back on spending due to inflation and higher interest rates, companies may find it harder to rely on subtle price adjustments.

Consumers have become more aware of shrinkflation, making it a riskier strategy.

Layoffs Could Become Another Cost-Cutting Measure

If higher fuel costs persist and businesses cannot pass the expenses onto customers, companies may be forced to cut costs elsewhere.

One potential outcome could be layoffs.

“There’s no free lunch. It’s going to show up somewhere,” Bethune said.

In other words, rising oil prices triggered by geopolitical conflict could eventually affect not only the cost of goods but also employment levels.

The Bottom Line

While gasoline prices often dominate headlines during global conflicts, the broader economic impact can be far-reaching. Higher oil prices increase transportation costs, which eventually filter into the prices of food, retail goods, and other consumer products.

If the conflict involving Iran continues and energy prices remain elevated, American households could soon feel the effects across multiple areas of daily spending—from grocery bills to delivery fees and beyond.
