This study examined the contemporaneous effect of global economic policy uncertainty on Nigeria’s export earnings, using Nigerian data that spans from 1997 to 2016. The theoretical framework relied on the contemporaneous theory of external vulnerability, which posits that macroeconomic shocks from dominant economies could be transferred to lesser dominant economies through international linkages of global economies and financial market. To achieve objective, this study employed the ARDL and GARCH estimation techniques, to estimate the effect of global economic policy uncertainty on Nigeria’s export earnings. The results revealed the adverse effect of global economic policy uncertainty on Nigeria’s export earnings, affirming the vulnerability of Nigeria’s export earnings to external shocks. The practical implication of the finding is that developing economies could insulate their domestic macroeconomic environment from external shocks by diversifying their economies. Importantly, Nigeria should increase diversification of her export base as a coping strategy for protecting against the contemporaneous effect of global economic uncertainties.
