Abstract

The goal of this paper is to highlight the mechanisms through which shocks on commodities can affect the external stability of the CFA issued by the BEAC (apprehended through the External Coverage Rate of the currency - ECR). The choice of variables, namely: the ECR, the profits from the exploitation of natural resources on the one hand, the external public debt and inflation (control variables) on the other is made with reference to the literature, the financial history (crisis of the 1980s and financial turbulences of the years 2015-2019) and the current events (the Great Lockdown and the Russia-Ukraine war). The econometric strategy consists of a panel-VAR specification on which various diagnostic tests were applied (stationarity, number of lags, stability of the model and robustness). Our results show that shocks on commodities (including those on control variables) weaken the foreign exchange reserves dynamics in CEMAC. However, they do not compromise the credibility of the BEAC in the short term. Based on this, we make some policy recommendations.
