A global energy shock triggered by the ongoing conflict between the U. S. and Iran has sent U. S. inflation soaring in March, with the Consumer Price Index (CPI) rising to an annual rate of 3.3%. This marks the highest inflation reading in nearly two years, a sharp reversal from the cooling trend observed in recent months. The surge is primarily attributed to a spike in energy prices following U. S. attacks on Iran, which began in late February.
The conflict has disrupted global oil supplies, particularly through the Strait of Hormuz, a critical chokepoint for energy shipments. This disruption has led to a significant increase in gasoline prices, which jumped 21.2% in March alone, representing the largest monthly increase since the Bureau of Labor Statistics began tracking the data in 1967. U. S. gasoline prices have soared nearly 40% since the conflict erupted, reaching an average of $4.15 a gallon. Brent crude, the global benchmark for oil prices, has also risen sharply, trading at $95.88 a barrel as of Friday morning, compared to $73 before the war.
The rise in energy costs is rippling through the economy, impacting not only consumers at the pump but also businesses and various sectors. Higher transportation costs are affecting the prices of goods, including food, potentially leading to broader inflationary pressures. While a tentative ceasefire agreement between the U. S. and Iran has been reached, experts caution that the lagged impact of the energy shock will continue to affect consumers throughout the remainder of 2026.
Despite the overall inflation surge, "core" inflation, which excludes volatile food and energy prices, rose modestly by 0.2% in March, or 2.6% annually. This suggests that the energy shock is the primary driver of the current inflationary pressures, potentially giving the economy some room to absorb the price increases. However, the longer the conflict persists, the greater the risk of sustained inflationary pressures and broader economic consequences.
