Macroeconomics plays an important role in influencing firm value and performance. This study aims to analyze the effect of inflation, exchange rates, interest rates, and Gross Domestic Product (GDP) on firm value, with firm performance as a mediating variable. Firm performance in this study is proxied by liquidity, which is measured using the Current Ratio (CR), representing one specific dimension of firm performance rather than its overall performance, while firm value is proxied by the Price Earning Ratio. The study was conducted on infrastructure sector companies listed on the Indonesia Stock Exchange for the 2019–2023 period, using a purposive sampling method. Data analysis was carried out through classical assumption tests, multiple linear regression, and mediation analysis using the Sobel test. The results showed that inflation, interest rates, and GDP had a significant effect on Current Ratio, but exchange rates did not. Meanwhile, inflation, interest rates, and exchange rates had a significant effect on firm value, but GDP did not. The mediation test showed that Current Ratio only significantly mediated the effect of inflation on firm value. These findings indicate the importance of liquidity management and strategies in dealing with macroeconomic risks. Further research is recommended to examine other mediating variables and different industrial sectors.
