The United Kingdom had joined the European Exchange Rate Mechanism, committing to maintain sterling's exchange rate above a prescribed lower limit. Speculative pressure in currency markets made this commitment increasingly untenable, as traders bet against the pound's ability to hold its required level.
On 16 September 1992, the UK Government failed to defend sterling's position within the ERM despite emergency measures, including interest rate hikes. Facing unsustainable market pressure, the government was forced to withdraw the pound from ERM I entirely, an event that became known as Black Wednesday.
The crisis severely damaged the economic credibility of John Major's Conservative government. The party suffered a landslide defeat at the 1997 general election and remained out of power until 2010. Paradoxically, sterling's subsequent depreciation and the adoption of inflation targeting contributed to a period of economic recovery in the years that followed.
