shadow banking system details

The shadow banking system or the shadow financial system consists of non-depository banks and other financial entities (e.g., investment banks, hedge funds, and money market funds) that grew in size dramatically after the year 2000 and play an increasingly critical role in lending businesses the money necessary to operate. By June 2008, the U.S. shadow banking system was approximately the same size as the U.S. traditional depository banking system. The equivalent of a bank run occurred within the shadow banking system during 2007-2008, when investors stopped providing funds to (or through) many entities in the system. Disruption in the shadow banking system is a key component of the ongoing subprime mortgage crisis.
