What was the name of the U.S. market collapse in October 1989 after the leveraged buyout of United Airlines failed?

The October 1989 U.S. market collapse after United Airlines’ leveraged buyout failed was called the Friday the 13th mini-crash.

On Friday, October 13, 1989, the Dow Jones Industrial Average fell 190.58 points, or about 6.9 percent. The immediate trigger was the collapse of a proposed leveraged buyout of United Airlines. Investors had expected financing for the deal, and its failure raised concerns about speculative acquisitions and the availability of credit.

The decline was much smaller than the 1987 global crash, so it became known as a mini-crash. It also occurred on a Friday the 13th, giving the episode its memorable name. The event is sometimes confused with Black Monday, which refers to October 19, 1987, when markets worldwide suffered a far larger one-day shock. The 1989 decline did not produce the same prolonged global panic, but it demonstrated how takeover finance could affect broad market confidence.
