Investigating the Role of Policy Rate and Money Supply in Nigeria's Inflation Stability

This study examines the factors influencing inflation stability in Nigeria from 2011Q1 to 2023Q1. We employ an ARDL model to assess the impact of monetary policy rate, money supply, crude oil price, GDP growth, and government budget deficit on inflation. Our findings reveal that broad money and fiscal deficit exert a positive and statistically significant influence on inflation in both the short and long run. Interestingly, monetary policy rate only affects inflation in the short term. These results suggest that Nigerian policymakers should prioritize managing broad money and fiscal deficits to achieve long-term inflation stability.
