Purpose: Policy makers, academics and journalists have frequently discussed the link between oil prices and exchange rate in recent years. After the 2014 World’s biggest oil price drop that plunge CEMAC oil exporting countries into an external liquidity strain, due to the pressure raised on Euro to which CFA franc is pegged, this paper revisits the dependence between crude oil price changes and exchange rate.
 Methodology: Crude oil price is the main independent variable, though other independent variables have been considered. The change in crude oil price is captured through differentiation of average yearly crude oil prices. The real effective exchange rate (RER) is the dependent variable, captured with the consumer’s price index (CPI), which describes the strength of a currency relative to a basket of other currencies. The data used in this study were extracted from Word Bank Development Indicators (WBDI, 2020) and World Bank Commodity Price Data. The study covers the period 1990-2018. The main channels of transmission used in this paper are the terms of trade channel, the wealth or portfolio channel and the anticipation or expectation channel. A panel autoregressive distributive lag (ARDL) model was used.
 Findings: The result shows that there is a short run positive and insignificant effect of oil price changes on exchange rate of CEMAC oil producing countries. In the long-run, there is rather a negative and significant impact of oil price changes on exchange rate. More concretely, a unit increase in oil prices depreciates exchange rate of these countries by 0.4340 units and this is significant at 1%. The short run Cross-country analysis shows that the effect is negatively significant for Cameroon and Chad; positive and significant for Democratic Republic of Congo and Equatorial Guinea; but positive and not significant for Gabon. These results are likely linked to structural differences between countries as the dependence on oil revenue and the security situation are concerned.
 Recommendations: Given this negative long run damage of oil prices on exchange rate of CEMAC oil producing countries, it is highly advisable these countries increase direct investments in key economic non-oil sectors in order to reduce dependence. On the other hand, considering the unidirectional causality from exchange rate to oil prices, a policy of exchange rate anchor by BEAC is suitable in order to absorb the shock of oil price changes on exchange rate and eventually inflation in the these economies.
