Iran War Drives Inflation to Three Year High as Wages Fall Behind

Energy Crisis Fuels Inflation Surge

American consumers are feeling the pinch as inflation surged to 3.8% in April, its highest level in nearly three years, as the war in Iran causes a ripple effect across the economy and energy prices rise . For the first time since 2023, prices are now rising faster than wages, which could aggravate the affordability crisis that has already been gripping consumers .

The culprit behind this economic squeeze is clear: the Iranian closure of the Strait of Hormuz, a maritime trading route that facilitates the transport of about one-fifth of global oil supply . Before the Iran war, more than 20% of the world's energy supply traveled on oil and gas vessels through the Strait of Hormuz, off southern Iran. Since the war started, ship traffic has plunged to a trickle .

The immediate impact on American wallets has been severe. The price of jet fuel has surged 60% since the war with Iran started , while gas prices have climbed sharply since the war broke out, averaging $4.12 per gallon nationally on Monday, up 80 cents from a month earlier . Energy related costs jumped 3.8% on a monthly basis and were up 17.9% over the last 12 months, accounting for over 40% of the inflation increase .

Broader Economic Ripple Effects

The energy shock is spreading far beyond gas pumps. Tuesday's report also showed that other categories, such as "food at home," or grocery prices, jumped 0.7% in April, while services, which includes transportation, rose 0.5% from the month before. The jump in grocery prices was the highest in nearly four years . Airlines have responded by raising fees, with a number of airlines, including Delta, United and Southwest, have increased bag fees. Some international airlines have also implemented surcharges on ticket prices .

The pain is hitting American households where it hurts most. "Inflation is a regressive tax, which hits the ranks of those who can afford it least," KPMG chief economist Diane Swonk said . "The rise in diesel fuel, which touches just about everything, shows up rapidly on grocers' shelves," Swonk said. "The jump in diesel costs happened even faster [than gas prices], ahead of the spillover effects that shortages can have across supply chains, including fertilizer and the food supply."

The economic disruption extends globally, with "The closure of the Strait of Hormuz is more than an energy shock; it is roiling supply chains around the world in ways that echo the disruptions we saw during the pandemic," she wrote Tuesday .

Federal Reserve's Difficult Position

The inflation surge has put the Federal Reserve in an increasingly difficult position. Rising energy prices since the outbreak of the Iran war have led a number of forecasters to rewrite their interest rate predictions, with some economists saying there's a chance the Fed won't make cuts this year. "Given our higher headline and core PCE inflation forecast, we have revised our baseline to show only one 0.25-percentage-point rate cut in 2026, likely in December, but it is entirely plausible that the Fed won't deliver any rate cuts this year," EY-Parthenon chief economist Gregory Daco told investors in a report .

Some economists are even contemplating the unthinkable: rate hikes. Beth Hammack, president of the Federal Reserve Bank of Cleveland, told the Associated Press on Monday that while her preference is to hold the benchmark rate steady "for quite some time," a hike could become necessary if inflation stays stubbornly high. "I could see where we might need to raise rates if inflation stays persistently above our target," she said .

"Before the war, before we got the oil shock, I've been on the optimistic side of the rate — I believed rates could come down even multiple times in 2026," Goolsbee said. The energy shock "complicates that picture for me — that if we're truly not going to see any improvement in inflation, to me that starts pushing these decisions off to 2027 at the earliest," he said .

Looking Ahead

The duration of the conflict will largely determine the economic fallout. Swonk said Tuesday's report and the Hormuz issue suggest that consumers could continue to feel the ripple of effects of the energy and supply chain disruptions "well into 2027, even if the strait were to reopen tomorrow." The war has already entered its 11th week with no clear resolution in sight.

For ordinary Americans, the message is clear: the economic pain from this geopolitical crisis is just beginning. With wages falling behind inflation for the first time in years, households are facing a renewed affordability crisis reminiscent of the pandemic era. The Federal Reserve's tools to combat this type of supply-driven inflation are limited, leaving policymakers in the uncomfortable position of choosing between supporting employment and fighting price pressures.

The path forward depends largely on
