Which 1989 U.S. leveraged-buyout collapse helped trigger the October mini-crash?

The failed United Airlines deal helped trigger the October 1989 mini-crash.

On 13 October 1989, the market reacted sharply after the proposed leveraged buyout of United Airlines collapsed. The deal had depended on employee ownership and financing arrangements, and its failure undermined confidence in the highly leveraged takeover boom. The Dow Jones Industrial Average fell 190.58 points that day, about 6.9%.

The decline is often called the October 1989 mini-crash. It came two years after Black Monday and was also associated with concerns about junk-bond financing, takeover activity, and rising interest rates. Because the fall was connected to a specific failed corporate transaction, it is distinct from broad crashes caused by a banking or macroeconomic collapse.

The United Airlines episode is sometimes confused with the RJR Nabisco buyout, another landmark leveraged transaction of the era. RJR Nabisco’s deal was completed in 1989; the United Airlines transaction was the one whose collapse became the immediate market catalyst in October.
