 abstract={The objective of the article is to estimate the impact of energy commodity prices, particularly oil, coal, and natural gas, on disaggregated inflation in Poland. The empirical part was based on multiple regression models constructed using simple OLS methods, providing short-run analysis. The study focused on inflation in the areas of food, housing, transportation, and core inflation. The study revealed that energy commodity prices have a significant impact on three out of four considered inflation categories, with the nature of this interaction varying across sectors. Coal and natural gas prices had a substantial effect on housing sector inflation (ECPI), while oil prices exerted the most significant influence on transportation sector inflation (TCPI). None of the variables affected inflation in the food area. This type of differentiation underscores the importance of disaggregated inflation analysis. Macroeconomic control variables, such as the output gap, exchange rate, and interest rates, also played a crucial role in the model. A positive output gap increases inflationary pressure, and exchange rates, particularly the real effective exchange rate (REER), can suppress price growth, especially in import-dependent sectors like transportation. Interest rates also had a pronounced impact on inflation, highlighting their role as a monetary policy tool. The study contributes to the development of knowledge on the impact of energy commodity prices, particularly oil, coal, and natural gas, on disaggregated inflation in Poland.},
