Black Monday (1987)

DJIA (19 July 1987 to 19 January 1988).

FTSE 100 Index (19 July 1987 to 19 January 1988).

In finance, Black Monday refers to Monday, October 19, 1987, when stock markets around the world crashed, shedding a huge value in a very short time. The crash began in Hong Kong and spread west to Europe, hitting the United States after other markets had already declined by a significant margin. The Dow Jones Industrial Average (DJIA) dropped by 508 points to 1738.74 (22.61%).^[1]

In Australia and New Zealand the 1987 crash is also referred to as Black Tuesday because of the timezone difference. The terms Black Monday and Black Tuesday are also applied to October 28 and 29, 1929, which occurred after Black Thursday on October 24, which started the Stock Market Crash of 1929.

Market effects

By the end of October, stock markets in Hong Kong had fallen 45.5%, Australia 41.8%, Spain 31%, the United Kingdom 26.45%, the United States 22.68%, and Canada 22.5%. New Zealand's market was hit especially hard, falling about 60% from its 1987 peak, and taking several years to recover.^[2] The Black Monday decline was the largest one-day percentage decline in the Dow Jones. (Saturday, December 12, 1914, is sometimes erroneously cited as the largest one-day percentage decline of the DJIA.^[3][4] In reality, the ostensible decline of 24.39% was created retroactively by a redefinition of the DJIA in 1916.^[5][6])

Following the stock market crash, a group of 33 eminent economists from various nations met in Washington, D.C. in December 1987, and collectively predicted that “the next few years could be the most troubled since the 1930s”.^[7] However, the DJIA was positive for the 1987 calendar year. It opened on January 2, 1987 at 1,897 points and closed on December 31, 1987 at 1,939 points. The DJIA did not regain its August 25, 1987 closing high of 2,722 points until almost two years later.

Timeline

Timeline compiled by the Federal Reserve.

In 1986, the United States economy began shifting from a rapidly growing recovery to a slower growing expansion, which resulted in a "soft landing" as the economy slowed and inflation dropped. The stock market advanced significantly, with the Dow peaking in August 1987 at 2722 points, or 44% over the previous year's closing of 1895 points.

On October 14, the DJIA dropped 95.46 points (a then record) to 2412.70, and fell another 58 points the next day, down over 12% from the August 25 all-time high.

On Thursday, October 15, 1987, Iran hit the American-owned supertanker, the Sungari, with a Silkworm missile off Kuwait's main Mina Al Ahmadi oil port. The next morning, Iran hit another ship, the U.S. flagged MV Sea Isle City, with another Silkworm missile.

On Friday, October 16, when all the markets in London were unexpectedly closed due to the Great Storm of 1987, the DJIA closed down another 108.35 points to close at 2246.74 on record volume. American Treasury Secretary James Baker stated concerns about the falling prices. That weekend many investors worried over their stock investments.

The crash began in Far Eastern markets the morning of October 19. Later that morning, two U.S. warships shelled an Iranian oil platform in the Persian Gulf in response to Iran's Silkworm missile attack on the Sea Isle City.^{[8] [9]}

Causes

Possible causes for the decline included program trading, overvaluation, illiquidity, and market psychology.

A popular explanation for the 1987 crash was selling by program traders, most notably as a reaction to the computerized selling required by portfolio insurance hedges.^[10] However, economist Dean Furbush points out that the biggest price drops occurred when trading volume was light.^[11] In program trading, computers perform rapid stock executions based on external inputs, such as the price of related securities. Common strategies implemented by program trading involve an attempt to engage in arbitrage and portfolio insurance strategies. As computer technology became more available, the use of program trading grew dramatically within Wall Street firms. After the crash, many blamed program trading strategies for blindly selling stocks as markets fell, exacerbating the decline. Some economists theorized the speculative boom leading up to October was caused by program trading, and that the crash was merely a return to normalcy. Either way, program trading ended up taking the majority of the blame in the public eye for the 1987 stock market crash. U.S. Congressman Edward J. Markey, who had been warning about the possibility of a crash, stated that "Program trading was the principal cause."^[12]

New York University's Richard Sylla divides the causes into macroeconomic and internal reasons. Macroeconomic causes included international disputes about foreign exchange and interest rates, and fears about inflation.

The internal reasons included innovations with index futures and portfolio insurance. I've seen accounts that maybe roughly half the trading on that day was a small number of institutions with portfolio insurance. Big guys were dumping their stock. Also, the futures market in Chicago was even lower than the stock market, and people tried to arbitrage that. The proper strategy was to buy futures in Chicago and sell in the New York cash market. It made it hard – the portfolio insurance people were also trying to sell their stock at the same time.^[13]

Economist Richard Roll believes the international nature of the stock market decline contradicts the argument that program trading was to blame. Program trading strategies were used primarily in the United States, Roll writes. Markets where program trading was not prevalent, such as Australia and Hong Kong, would not have declined as well, if program trading was the cause. These markets might have been reacting to excessive program trading in the United States, but Roll indicates otherwise. The crash began on October 19 in Hong Kong, spread west to Europe, and hit the United States only after Hong Kong and other markets had already declined by a significant margin.

Another common theory states that the crash was a result of a dispute in monetary policy between the G7 industrialized nations, in which the United States, wanting to prop up the dollar and restrict inflation, tightened policy faster than the Europeans. U.S. pressure on Germany to change its monetary policy was one of the factors that unnerved investors in the run-up to the crash. The crash, in this view, was caused when the dollar-backed Hong Kong stock exchange collapsed, and this caused a crisis in confidence.^{[citation needed]}

Some technical analysts claim that the cause was the collapse of the US and European bond markets, which caused interest-sensitive stock groups like savings & loans and money center banks to plunge as well. This is a well documented inter-market relationship: turns in bond markets affect interest-rate-sensitive stocks, which in turn lead the general stock market turns.^{[citation needed]}
