This study aims to examine the influence of inflation and interest rates on the stock returns of PT Bank Central Asia Tbk (BCA) during the period 2020–2024. This research employs secondary data with a total of 60 observations, obtained from official sources, including Bank Indonesia, the Central Bureau of Statistics, and Yahoo Finance. The analytical methods used in this study include descriptive analysis, classical assumption tests, and multiple linear regression to evaluate both partial and simultaneous effects. The results indicate that inflation has no significant effect on BCA’s stock returns, as evidenced by a significance value of 0.374 (> 0.05). Similarly, interest rates also show no significant effect on stock returns, with a significance value of 0.302 (> 0.05). Simultaneously, inflation and interest rates do not have a significant influence on stock returns, as reflected by an F-test significance value of 0.441 (> 0.05). These findings suggest that fluctuations in inflation and interest rates during the study period are unable to explain variations in BCA’s stock returns. Overall, BCA’s stock return movements are more strongly influenced by internal company factors, fundamental stability, and market sentiment rather than macroeconomic variables such as inflation and interest rates. This study highlights the importance of strong financial performance and corporate reputation in maintaining stock return stability amid economic fluctuations.
