U.S. consumer inflation accelerated sharply in March 2026, with price gains tied largely to a spike in energy costs amid the U.S.-Israel conflict with Iran. Data showed the Consumer Price Index (CPI) rose 0.9% from February and was up 3.3% from a year earlier, the biggest monthly increase in nearly two years.
The report pointed to energy as the dominant driver. The energy index climbed 10.9% in March, while gasoline prices surged 21.2%, accounting for nearly three-quarters of the overall monthly CPI increase. Airfares also moved higher, rising 2.7% on the month and 14.9% year-over-year.
Officials and market participants have been closely watching the inflation impact of the conflict, particularly after Iran’s blockade of the Strait of Hormuz, a key route for global oil shipments. The inflation data underscored how disruptions around major energy transit corridors can quickly feed into consumer prices, especially through fuel and transportation-related categories.
By contrast, underlying inflation pressures appeared more contained. Core CPI, which excludes food and energy, increased 0.2% in March and 2.6% from a year earlier. The annual inflation rate had not been above 3% since summer 2024, highlighting how the latest jump is occurring after a period of comparatively steadier price trends.
Energy markets remained central to the outlook described in the report. Even after a temporary ceasefire agreement contributed to a pullback in oil prices, U.S. crude oil was still 10% above pre-conflict levels and nearly 30% higher since the start of the year. That persistence suggests the energy shock has not fully unwound, keeping pressure on headline inflation measures.
The inflation surge arrives alongside signs of softer growth and weaker sentiment. Q4 2025 GDP growth was revised down to 0.5%, and consumer confidence fell 10.7%, adding to uncertainty that had already been elevated following earlier impacts from tariffs. Together, these developments complicate the policy backdrop as the Federal Reserve weighs future interest rate decisions.
At the same time, the labor market continued to show resilience. Employers added 178,000 jobs in March, and the unemployment rate declined to 4.3%. The combination of stronger headline inflation, mixed growth signals, and steady hiring leaves policymakers balancing inflation risks against broader economic momentum.
