The world market for crude oil refers to the total demand for and supply of crude oil globally. It is a market where producers and consumers of crude oil from different countries come together to buy and sell oil. The price of crude oil is determined by the interaction of global supply and demand. The Organization of the Petroleum Exporting Countries (OPEC) plays a significant role in influencing the world market for crude oil by controlling the supply of oil from its member countries. However, the market is also influenced by non-OPEC oil-producing countries and other factors such as geopolitical events and economic conditions.
