[Why is so important just for the oil price to go up when Iraq is so rich in natural resources and not to forget agriculture?]
I’m going to try not to over-complicate it, because it really is a simple matter.
You are correct, Iraq is indeed blessed with much natural resources, agriculture, and more!
But in spite of that, there is still a finite amount of oil beneath the surface, and if they are to get the most out of their efforts and have the best chances of RVing and sustaining a higher rate, their income from oil sales has a direct impact on that.
Therefore, higher price of oil = better for CBI.
