Abstract

An efficient stock market supports economic growth and is a barometer of South Africa’s financial health. Our research delves into how macroeconomic variables impact stock prices in South Africa by investigating yearly time series data ranging from 2000 to 2023. We utilise Johansen’s cointegration test and the Vector Error Correction Model (VECM) to investigate the equilibrium relationship between stock market prices and critical macroeconomic factors like inflation (INFL), trade rate (TR), money supply (MS) and exchange rate (EXCH). The study findings indicate that these factors are correlated in the long run, indicating a lasting correlation between specific macroeconomic indicators and stock market prices. Stock market prices are affected positively by exchange rates and inflation, as well as by the money supply; however, trade rates have a negative impact according to the analysis of short-term financial dynamics, which suggests that adjustments are made to reach a long-term equilibrium despite the lesser immediate effects of macroeconomic factors. Granger causality tests show that macroeconomic factors influence stock market prices over long and short-term periods. This highlights the importance of the stock market as an indicator of trends and signals potential shifts in the broader economy, which policymakers and investors should keep a close eye on as an early warning system.
