The crash was apparently caused by a reaction to a news story of the breakdown of a $6.75 billion leveraged buyout deal for UAL Corporation, the parent company of United Airlines.
When the UAL deal fell through, it helped trigger the collapse of the junk bond market.
The deal unraveled because the Association of Flight Attendants pulled out of the deal when management, in negotiations over an Employee Stock Ownership Plan (ESOP) designed to fund the leveraged buyout, refused to agree to terms.
Since most market participants blame the UAL deal as the culprit, survey researcher William Feltus and Robert Shiller, the author of Irrational Exuberance, conducted a telephone survey of 101 market professionals in the business days following the crash, asking if they had heard about the UAL news before or after the crash: 36% surveyed said they had heard about it before the losses set in, and 53% said afterwards.
[2] The crash is often pinpointed as the start of the early 1990s recession, but the surprisingly-low growth rates (almost 0 percent) during the summer months and the savings and loan crisis earlier in the year had triggered the crisis almost concurrently with the mini-crash, which, in turn, got blamed by the public (the memory of the 1987 crash still being fresh) as the true culprit of the recession.
