What is Shadow Banking?

"The Financial Stability Board (2012) describes shadow banking as “credit intermediation involving entities and activities (fully or partially) outside the regular banking system”. This is a useful benchmark, but has two weaknesses:
First, it may cover entities that are not commonly thought of as shadow banking, such as leasing and finance companies, credit-oriented hedge funds, corporate tax vehicles, etc. (...)
Second, it describes shadow banking activities as operating primarily outside banks."


"An alternative – ‘functional’ – approach treats shadow banking as a collection of specific intermediation services. Each of them responds to its own demand factors (e.g., demand for safe assets in securitisation, the need to efficiently use scarce collateral to support a large volume of secured transactions, etc.). The functional view offers useful insights. It stresses that shadow banking is driven not only by regulatory arbitrage, but also by genuine demand, to which intermediaries respond. This implies that in order to effectively regulate shadow banking, one should consider the demand for its services and – crucially – understand how its services are being provided (Claessens et al. 2012)."
