Purpose The purpose of this paper is to evaluate the influence of VND/USD exchange rate on Vietnamese coffee export price (PVN). Design/methodology/approach The study uses cointegration test, Granger causality test and vector autoregression (VAR) model. Findings The results reveal that there is no co-integrating equation between two variables. It means the exchange rate does not have an effect on PVN in the long run. Furthermore, there is one Granger causality relationship between VND/USD exchange rate and PVN in the short run, but not vice versa. The study suggests that the first previous period of PVN is the most closely related variable which has the greatest impact on the variation of PVN among the selected variables, meanwhile the effect of VND/USD exchange rate on it, contrarily, is positive and very trivial. Originality/value In overall, the impact of VND/USD exchange rate on Vietnamese coffee export price (PVN) has been analyzed deeply in this research by applying new approaches.
