The National Bank of Poland published its March 2026 core inflation indices, showing a year-on-year Consumer Price Index (CPI) increase of 3.0% and inflation excluding food and energy prices of 2.7%. The release indicates an acceleration across the core measures compared with February 2026. Inflation excluding administered (state-controlled) prices rose to 2.7% from 1.6% a month earlier, while inflation excluding the most volatile prices increased to 3.0% from 2.3%. The 15% trimmed mean measure moved up to 2.9% from 2.2%. The National Bank of Poland reiterated that it computes the four core indices monthly to better identify sources of inflation and assess persistence, noting that the core measure excluding food and energy is commonly used in inflation targeting because it is more responsive to monetary policy than food and energy prices.
