The main objective of this study is to quantify the implications of changes in trade of Cameroon on the welfare of its monetary households. Specifically, it is to assess due to a shock on the world oil price implications of an increase or a decrease in exports / imports from Cameroon to its trading partners on household consumption in Cameroon using the static computable general equilibrium models. The results of this study allow us to show interest in Cameroon to strengthen cooperation / exchange and accelerate the process of regional integration within the CEMAC. For industrial imports and agricultural exports , the respective variations are is ( 101.88 % ) and ( 35.68 %) are negatively correlated with monetary welfare. Variation are (-96.85 % for urban households) and (- 98.97 % for rural households). So Cameroon needs to increase intra-zone trade as required by the UNCTAD (2013).
