The International Monetary Fund (IMF) is the intergovernmental organization that oversees the global financial system by following the macroeconomic policies of its member countries, in particular those with an impact on exchange rate and the balance of payments. It has 187 member states, working to foster global monetary cooperation, secure financial stability, facilitate international trade, promote high employment and sustainable economic growth, and reduce poverty around the world.
It is an organization formed with a stated objective of stabilizing international exchange rates and facilitating development through the enforcement of liberalising economic policies on other countries as a condition for loans, restructuring or aid. It also offers loans with varying levels of conditionality, mainly to poorer countries. Its headquarters are in Washington, D.C., United States. The IMF's relatively high influence in world affairs and development has drawn heavy criticism from some sources.
Following a picture of the emblem on Yahoo News, the flag was constructed. The emblem of the IMF was shown on a red background in a Yahoo News article on 12 March 2004.
The IMF and World Bank do have flags, but I don't think they are ever flown at headquarters. Where I have seen them displayed publicly is on cars carrying IMF/WB officials in charge of their offices in countries where this is customary.
A photo at the Burkina president's website shows what seems to be the flag of IMF/FMI: blue with a yellow logo quite different from the one we show above.
