The U.S. Treasury Department wants international financial regulators to stop using the term "shadow banking" when referring to non-bank lenders, according to a report released Thursday. Instead, it wants such activities to be referred to as "market based finance." Per the report:

Etymology: The term "shadow banking" was coined by former bond fund manager Paul McCulley in 2007, and soon became ubiquitous as such lending helped spark the following year's financial crisis. Today the term is used fairly broadly, particularly as the securitization mania of 2007 has given way to new lending booms like private credit funds.

Bottom line: While "shadow banking" may be a pejorative term — which seems to be Treasury's gripe — it hasn't stopped the industry's rapid growth. Nor has that growth sparked increased oversight, as non-bank lenders continue to operate under much less oversight than can their banking peers.
