This research examines the relationship between aggregate supply and inflation in Iraq during (2004-2023) through deviations in aggregate supply that lead to changes in output and inflation. The core issue of the research lies in how any change in aggregate supply results in a shift of the aggregate supply curve from its initial position. This study employed a deductive methodology, theoretical frameworks, descriptive and quantitative assessments, and econometric techniques to analyze the connection between aggregate supply, which is treated as a dependent variable, and inflation, categorized as the independent variable. The findings of the analysis validated the hypothesis and confirmed a statistically significant association between the explanatory variable, identified as aggregate supply, and the dependent variable, recognized as inflation. Additionally, we outline a prospective research agenda and highlight the governance of oil revenues that aid in diversifying income sources to bolster resilience against shocks to aggregate supply.
