Inflation climbed sharply in April, reaching 3.8 percent — its highest level in nearly three years — according to data released by the Bureau of Labor Statistics. The jump is largely driven by surging energy prices caused by the ongoing war in Iran, which is creating widespread economic ripple effects.
This marks a troubling shift for American households. For the first time since 2023, prices are now rising faster than wages. Wage growth has slowed to 3.6 percent, down from nearly 4 percent last November. As a result, many families are finding it harder to keep up with rising costs, worsening an affordability crisis that has already strained budgets for years.
Energy Prices Lead the Surge
Increased energy costs made up more than 40 percent of the overall monthly rise in inflation. The energy index itself jumped 3.8 percent in April. As of early May, the average price of a gallon of gas had reached $4.50, while oil prices had climbed more than 70 percent since the beginning of the year.
The conflict in Iran has sharply reduced oil shipments through the Strait of Hormuz, a critical waterway that normally carries over 20 percent of the world’s energy supply. Ship traffic there has dropped dramatically, echoing supply chain problems seen during the pandemic.
These energy shocks are showing up quickly in everyday prices. Grocery prices (“food at home”) rose 0.7 percent in April — the largest monthly increase in nearly four years. Economist Diane Swonk of KPMG explained that rising diesel fuel costs affect almost everything on store shelves, from transportation to fertilizer used in farming. Airfares also surged, climbing 20 percent from a year earlier, as jet fuel prices jumped 60 percent. Airlines such as Delta, United, and Southwest have responded by raising bag fees and other charges. Even the U.S. Postal Service added temporary surcharges to cover higher fuel expenses.
Core Inflation and Other Details
Core inflation, which strips out volatile food and energy prices, rose 0.4 percent from the previous month — higher than economists had expected. Month-over-month, overall inflation increased 0.6 percent.
Not all categories saw increases. Prices fell slightly for new vehicles, medical care, health insurance, and communications. Used vehicle prices remained flat, and vehicle maintenance costs edged down.
Long-Term Concerns
Swonk described inflation as “a regressive tax” that hurts lower-income families the most. She warned that the situation is likely to get worse before it improves. Energy costs are still working their way through the economy and could continue pushing up prices for months. Disruptions to global supply chains may affect consumers well into 2027, even if the Strait of Hormuz reopens soon.
While the April inflation figures matched economists’ expectations in some ways, the faster-than-expected rise in core inflation and the ongoing energy crisis suggest challenges ahead for both consumers and policymakers.
