In February 1987, leaders signed the Louvre Accord to help stabilize money markets. However, many people did not believe this plan would work. This lack of faith created a crisis of confidence. Some believe computer models used for "portfolio insurance" made the fall even faster.

Before the crash, the market had been doing very well. For five years, the Dow Jones Industrial Average rose steadily. It went from 776 in 1982 to a peak of 2,722 in August 1987. During this time, many markets around the world also grew. In October 1987, things began to shift quickly in the United States. On October 14, new tax bills and trade figures caused prices to drop. By the time the weekend arrived, there was a lot of pressure to sell.

When the market opened on Monday, the crash was massive. The Dow Jones Industrial Average fell by 508 points. That is a 22.6 percent drop in just one day.

This was the largest one-day percentage drop in its history. The volume of trading was so huge that it overwhelmed computers. Many communication systems shut down for an hour or more. This left many traders feeling very confused and worried.

Central banks worked hard to stop the damage from spreading. The Federal Reserve in the United States acted very quickly.
