Abstract: Understanding the role of the exchange rate behaviour in domestic prices is crucial for monetary authorities in anticipating inflation. Over the last 28 years (1994 – 2022), the inflation rate in South Africa has increased, averaging at 5.7% per year. It is believed that some of the increase in the inflation rate is a result of trade, hence this study aims at identifying how much of the changes in the exchange rate is passed on to domestic inflation. This idea is of interest in a country like South Africa that had implemented inflation targeting. The study identifies two channels of the exchange rate pass-through (ERPT); direct and indirect. the direct involves the change in import prices that is associated with the change in the exchange rate. The indirect channel involves the change in consumer price index (CPI) and the producer price index (PPI) that is associated with a change in import prices. The study uses monthly data from 1994 – 2022 to identify the speed and the magnitude of the exchange rate pass-through to domestic prices in the short-run and the long-run. Using the vector autoregressive model (VAR) and the vector error correction model the results shows that the magnitude of the exchange rate pass-through to import prices is relatively higher than the exchange pass-through to the CPI and PPI and that import prices; CPI and PPI increases immediately after an increase in the exchange rate.
