This study aims to analyze the influence of the exchange rate, money supply, and state budget deficit on inflation in indonesia, both simultaneously and partially. the research method used was multiple regression analysis with secondary data obtained from various official sources such as the central statistics agency and the indonesian bank. the study results show that simultaneously, the exchange rate, money supply, and state budget deficit have a significant influence on inflation. partially, the exchange rate and state budget deficit show a positive and significant influence on inflation, while the money supply also has an influence but with lower significance, which shows that this variable does not have a strong enough impact to statistically influence the inflation rate in indonesia in the research period used. thus, this research suggests the need for more attention to managing the exchange rate and state budget deficit in efforts to control inflation in indonesia, while the influence of the money supply requires further study to understand the dynamics and other factors that may influence it. keywords: exchange rate, money supply, state budget deficit, inflation, indonesia.
