An Oil Market Crash is a Timeline Event that occurs at random 3 to 4 year stints. While the event is happening, the commodity prices of Crude Oil and Oil Products decreases by 50% as oil production exceeds demand. If the island has an oil refinery, crashes could be a good time to start importing oil from the Middle East, withholding exports of the resulting Oil Products, and then exporting all of them once the crash is over for a large profit.
