U.S. Inflation Surges to 3.3% in March as Energy Prices Spike

The consumer price index for March 2026 rose to an annual 3.3%, the fastest pace since May 2024 and almost a full point above February’s 2.4% rate. A 0.9% monthly gain lifted headline inflation to its highest level in nearly two years.

Energy prices drive the spike

The jump is anchored in soaring energy costs tied to the war in Iran. National gasoline prices broke the $4‑per‑gallon barrier for the first time in three years, and oil prices have climbed sharply as the conflict ripples through global markets.

Core inflation stays elevated

Even without food and energy, core CPI is projected at 2.7% year‑over‑year, while the Fed’s preferred PCE price index held at 2.8%. Both figures sit well above the Federal Reserve’s 2% target, signaling persistent price pressures.

Policy outlook

The Fed now faces a tighter balancing act. While the impact of earlier tariffs is fading, the energy shock means policymakers must decide whether to adjust interest rates or rely on the gradual cooling of other price components.
