The United States’ Core Consumer Price Index (Core CPI) rose 0.2% month-over-month in March 2026, matching February’s 0.2% increase, according to data updated on 10 April 2026. On a month-over-month basis, this indicates that the pace of underlying inflation—excluding volatile food and energy components—remained unchanged heading into the spring.
The comparison period is measured on a month-over-month basis, meaning the March figure reflects price changes relative to February, while the previous reading reflected February’s changes compared with January. With both months posting identical 0.2% gains, the data suggest a period of short-term stability in core price pressures, an important gauge for policymakers and markets tracking the trajectory of inflation.
