This paper aims to determine the effect of the Covid-19 scenario, the Rupiah Exchange Rate, on the Indonesia Composite Index via the Balance Of Trade. From September 2019 to August 2021, the variables employed in this study are the development of active cases in Indonesia, as well as macroeconomic indicators such as the Rupiah Exchange Rate (ER), Balance Of Trade (BOT), and Indonesia Composite Index (ICI). The research approach used in this study is a quantitative descriptive study with the analytical tool WarpPls version 5.0. The obtained results prove that C-19 has a considerable adverse influence on BOT in Indonesia. The second finding is that ER has a significant favourable impact on BOT. Thirdly, C-19, ER, and BOT have a strong beneficial effect on ICI. The Sobel test established that BOT can mediate the effects of C-19 and ER on ICI. The research concludes that investors should monitor the evolution of C-19 and macroeconomic variables such as ER and BOT that substantially impact ICI movements before participating in the capital market.
