The main objective of this study is to investigate the Granger Causality between Oil Price and Inflation during the period 1990 to 2013, using vector autoregressive model (VAR), Phillips?perron test, Augmented Dickey- fuller test, Johansen co-integration test, variance decomposition and impulse response function, as well as using four variables of Gross Domestic Product (GDP), Exchange rate(ER), Oil price (OP), Inflation (INF). The main results of this study showed that OP does not Granger cause GDP, and the GDP does not Granger cause OP, so there is bidirection from GDP to OP. Impulse response function shows that there is a negative effect of OP to GDP and a Positive effect of OP to ER and INF. Co-integration test reveals the existence of the three vector co-integration, suggesting a long-run relationship among variables
