What was the name of the 1992 British currency-market crisis when the pound left the ERM?

The 1992 British currency-market crisis when the pound left the ERM was called Black Wednesday.

Black Wednesday occurred on September 16, 1992, when the United Kingdom suspended sterling’s membership in the European Exchange Rate Mechanism. The ERM required participating currencies to remain within agreed bands against one another. Speculators believed Britain could not maintain sterling’s exchange rate without damaging the domestic economy through higher interest rates.

The British government raised interest rates and spent foreign-exchange reserves defending the pound, but the pressure continued. After sterling left the mechanism, it depreciated substantially. The episode damaged the Conservative government’s economic credibility and became a major political event. It is also called the 1992 sterling crisis. This event was a currency crisis rather than a conventional single-day stock-exchange crash.
