In financial markets, Black Monay is the name given to Monday, October 19, 1987, when stock markets around the world 'crashed', shedding a huge value in a very short period. The crash began in Hong Kong, spread west through international time zones 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 1739 (22.6%). By the end of October, stock markets in Hong Kong had fallen 45.8%, Australia 41.8%, Spain 31%, the United Kingdom 26.4%, 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. (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. Confusingly, in Australia the 1987 crash is also referred to as Black Tuesday because of the timezone difference)
