black market, the selling or buying of commodities at prices above the legal ceiling or beyond the amount allotted to a customer in countries that have placed restrictions on sales and prices. Such trading was common during World War II wherever the demand and the means of payment exceeded the available supply. Most of the warring countries attempted to equalize distribution of scarce commodities by rationing and price fixing. In the United States black-market transactions were carried on extensively in meat, sugar, tires, and gasoline. In Great Britain, where clothing and liquor were rationed, these were popular black-market commodities. In the United States, rationing terminated at the end of the war, but a black market in automobiles and building materials continued while the scarcity lasted. In the decades following World War II, as the countries of Eastern Europe were trying to industrialize their economies, extensive black-market operations developed because of a scarcity of consumer goods. Black marketing is also common in exchange of foreign for domestic currency, typically in those countries that have set the official exchange value of domestic currency too high in terms of the purchasing power of foreign money. Black-market money activities also grow when holders of domestic currency are anxious to convert it into foreign currency through a fear that the former is losing its purchasing power as a result of inflation. See also bootlegging.
