Oct 19, 1987 — Black Monday, where a shocking 22.6% plunge on Wall Street reverberated around the world. All 23 major world markets at that time collapsed: eight of them by more than 20%; three of them by more than 30%; and another three by more than 40%. Hong Kong won the bogey prize — it was down 45.8% — and the exchange had to be shut for a week after.
