The study looked at how oil prices affect the economies of eight countries in the Middle East and North Africa. They found that oil prices impact things like economic growth, consumer prices, and stock markets in both the short and long term. Oil-exporting countries see bigger changes in economic growth due to oil prices compared to oil-importing countries. The stock market tends to react negatively to oil price changes during financial crises. Overall, oil prices have a small effect on money market rates in the region.
