The focus of the study was to ascertain the interrelationship between budget deficit, inflation and economic growth in Nigeria. Various literatures were reviewed. The study period span from 1991 to 2022. Various econometric tests such as unit root test, cointegration test etc were employed. The study employed vector auto regression model and impulse response function and variance decomposition. The findings from the impulse response and variance decomposition analyses provide valuable insights into the interrelationships between fiscal deficits, inflation, and economic growth in Nigeria. While inflation is primarily driven by its own history, the influence of GDP and employment grows over time, suggesting that fiscal and monetary policies targeting both inflation and economic growth will be crucial for stabilizing the economy in the long run. Base on the findings of the study, the researcher recommend among others that given that inflation is largely self-driven in the short term, it is critical for policymakers to focus on controlling factors that can exacerbate inflationary pressures, such as excessive money supply growth or external shocks.
