A **black market**, **underground economy**, or **shadow economy** is a [clandestine](https://en.wikipedia.org/wiki/Secrecy) [market](https://en.wikipedia.org/wiki/Market_(economics)) or series of transactions that has some aspect of illegality or is characterized by some form of noncompliant behavior with an institutional set of rules.
