This study aims to analyze the role of monetary policy in addressing the budget deficit by examining the relationship between monetary policy tools and fiscal imbalance, and assessing their effectiveness based on the experiences of three selected countries (Malaysia, Turkey, and Chile). The significance of the research lies in highlighting the impact of monetary policy as a tool for achieving financial stability and enhancing economic performance. The research adopts both the descriptive and analytical approaches, utilizing advanced econometric models through EViews 12 to measure the impact of monetary policy instruments on the budget balance. The results reveal a cointegrated relationship between monetary policy tools—namely, exchange rate, broad money supply, and real interest rate—and the budget balance. Moreover, findings indicate that monetary policy requires varying timeframes to correct fiscal imbalances: approximately one year in Malaysia, three years and six months in Turkey, and two years and four months in Chile, due to short-term deviations from long-term equilibrium levels. The study concludes with several recommendations, the most prominent of which is the need to maintain real interest rates within balanced levels to reduce borrowing costs and ease fiscal pressures.
