The "Plunge Protection Team" (PPT) is a colloquial name given to the Working Group on Financial Markets. Created in 1988 to provide financial and economic recommendations to the U.S. President during turbulent market times, this group is headed by the Secretary of the Treasury; other members include the Chair of the Board of Governors of the Federal Reserve, the Chair of the Securities and Exchange Commission and the Chair of the Commodity Futures Trading Commission (or the aides or officials they designate to represent them).

The name "Plunge Protection Team" was coined by The Washington Post and first applied to the group in 1997.
