The global financial crisis and the subsequent uneven recovery have underscored the need for Africa's resilience to output and other shocks originated in the rest of the world. A comparison of two regional economic communities – the East African Community (EAC) and the Southern Africa Customs Union (SACU) – suggests that deeper intra-regional, and in particular intra-industry, trade ties have contributed to the EAC's resilience to external output shocks. More broadly, intra-regional and intra-African trade with fast-growing economies, together with geographically diversified trade links, can strengthen the capacity of African countries to absorb global output shocks. Besides helping shield countries from external shocks, intra-regional trade also supports economic diversification and participation in regional value chains.
