Which company’s failed buyout helped trigger the October 1989 U.S. stock-market mini-crash?

United Airlines’ failed buyout helped trigger the October 1989 U.S. stock-market mini-crash.

On Friday, October 13, 1989, a leveraged buyout of United Airlines collapsed after the proposed financing arrangement failed. United’s parent company, UAL Corporation, saw its share price plunge, and the shock contributed to a broader market decline. The Dow Jones Industrial Average fell 190.58 points, then a very large one-day move.

The episode became known as the Friday the 13th mini-crash. It was not as severe or as globally transformative as Black Monday in 1987, but it highlighted how highly leveraged takeovers and financing conditions could affect wider markets.

United Airlines is sometimes confused with other airline companies involved in later restructurings or bankruptcies. The relevant event here was the failed 1989 buyout proposal involving UAL, not an airline operating failure or a later merger.
