What it means
On a day in October 1987, US share prices fell very sharply, and regulators were alarmed at how quickly markets had moved. In 1988, an executive order created the President's Working Group on Financial Markets.
Its purpose was to improve cooperation among the main financial regulators and to look at ways of keeping markets stable. The group consists of senior officials: the Secretary of the Treasury, the chair of the Federal Reserve, the chair of the Securities and Exchange Commission and the chair of the Commodity Futures Trading Commission.
They meet to discuss issues such as market structure, risk and crisis planning. The body is a coordination forum, not a trading desk.
The nickname Plunge Protection Team became popular in the financial press and on the internet. It suggests a hidden squad that buys shares or futures contracts to stop prices falling.
Many traders talk about it when markets rebound suddenly after a drop. There is no public proof that the group buys shares to hold up the market.
Official statements describe its work as policy coordination and planning, and market moves usually have ordinary explanations such as news, trading flows and investor behaviour. Governments and central banks do intervene in some markets, but through publicised tools such as interest rates and lending programmes.
For business readers, the term is useful as an example of market folklore. It shows how people look for simple explanations when markets move sharply.
Finance professionals should rely on evidence, and be wary of any theory that cannot be tested. The idea also raises a real question about how far authorities should support markets in a crisis.
Support can reduce panic and protect the economy, but it can also encourage investors to take bigger risks, assuming they will be rescued. This tension is known as moral hazard and is a central issue in financial regulation.
In practice
Real-world examples.
Example
A shares trader sees the market fall by 3% in the morning and rebound by the afternoon. A colleague jokes that the Plunge Protection Team must have stepped in. The trader checks the news and finds that a positive economic report was published at lunchtime, which explains the recovery without any secret buying.
Example
A finance blogger writes that a sudden jump in index futures proves secret government buying. A reader asks for evidence, and the blogger cannot provide any. The post is later corrected to describe the claim as speculation.
Example
A university lecturer uses the nickname to introduce moral hazard to students. She explains that if investors believe a rescue will always come, they may take more risk than they otherwise would. Students discuss how regulators can calm markets without encouraging reckless behaviour, and they compare several historical crises.
Case study
Seen in the real world.
Greywater Capital is a fictional investment club, and this story is illustrative. After a sharp fall and recovery in share prices, several members were convinced that secret government buying had saved the market.
The club's treasurer decided to test the theory by looking at the facts. She found that the recovery began after a central bank statement and a better than expected company earnings report, and that prices had moved in line with other markets around the world. She presented a one-page timeline showing each news item and the market's reaction to it, so members could judge for themselves.
She also pointed out that a member who had bought shares purely on the belief of a hidden rescue had lost $3,000 when the next fall was not reversed. The club agreed to base decisions on evidence, with each investment idea supported by a written reason. The illustrative lesson is that comforting theories can be costly, and careful checking protects against them.
Watch out
Common mistakes.
- Treating the nickname as proof of a secret programme, when it is only a label from market folklore.
- Buying shares on the assumption that the government will always step in to stop a fall.
- Confusing the working group with central banks, which use open and published tools such as interest rates and lending facilities.
