| black market n.
|
The illegal buying and selling of goods above the price fixed by a government. Black markets usually develop when, because of war, disaster, or public policy, a government tries to set prices for commodities instead of allowing the normal operations of supply and demand to set prices.
Black Market
A type of economic activity that takes place outside of government-sanctioned channels. Black-market transactions typically occur as a way for participants to avoid government price controls or taxes, conducting transactions 'under the table'. The black market is also the means by which illegal substances or products - such as illicit drugs, firearms or stolen goods - are bought and sold.
Investopedia Commentary
While the black market is commonly associated with criminal activities involving drugs or weapons, it also has a financial component: black currency-exchange markets almost always appear when government controls on exchange rates prevent the use of natural exchange rates in the global marketplace.
