What was the 1987 global stock-market crash called in Hong Kong?

The 1987 global stock-market crash was called Black Monday in Hong Kong. Hong Kong’s Hang Seng Index fell sharply on 19 October 1987, the same calendar date that became infamous in several other markets.

The collapse was international rather than confined to the United States. Markets in Australia, the United Kingdom, Canada and other countries also recorded severe losses. In the United States, the Dow Jones Industrial Average fell 22.6 percent on 19 October, its largest one-day percentage decline.

Program trading, portfolio insurance, elevated valuations and investor concern about trade and interest rates all featured in explanations of the crash. “Black Monday” is also used for later market plunges, so the year 1987 is important when identifying this particular event.
