And analysis of the relationship between the two variables, as well as monitoring and analysis of the evolution of oil prices and global food commodity prices. And measuring the relationship between the two variables using Granger causality and the Autoregressive Vector model (VAR). The research found a one-way causal relationship in which oil price fluctuations affect the fluctuations of global food commodity prices. And there is a significant positive impact of the global financial crisis on the increase in oil price fluctuations. And a positive moral impact of the Corona crisis on the increase in the price fluctuations of food commodities. Therefore, economic policy makers and international investors must monitor changes that may occur in oil prices due to their impact on global food commodity prices.
