The international organization that influences and sets the price of oil in the international markets is the Organization of the Petroleum Exporting Countries (OPEC). OPEC is an intergovernmental organization made up of 14 oil-producing countries. These countries work together to control the supply of oil in the international markets, with the aim of stabilizing prices and generating income for their member countries. By controlling the supply of oil, OPEC can influence the price of oil in the international markets, making it a powerful player in the global energy market. IMF, ECOWAS, and OAU are not organizations that are involved in setting the price of oil.

ECOWAS (Economic Community of West African States) is a regional organization made up of 15 West African countries, aimed at promoting economic integration and development in the region. OAU (Organization of African Unity) is a defunct organization that was formed to promote unity and cooperation among African countries.
