Black Wednesday: How Sterling Broke the ERM (1992) - QuickFinanceStories

On September 16th, 1992, one man bet against the entire British government. And won. His name was George Soros.

And this is the story of how he broke the Bank of England. In 1990, Britain joined the European Exchange Rate Mechanism. The ERM was supposed to keep European currencies stable by pegging them together.

Britain pegged the pound to the German mark within a narrow band. The idea was simple: stable currency, stable economy. But there was a fundamental problem.

The British economy was in recession. Inflation was high. Unemployment was rising.

Britain needed lower interest rates to stimulate growth. But Germany had the opposite problem. After reunification, Germany raised interest rates to fight inflation.

After reunification, Germany raised interest rates to fight inflation.

And because the pound was pegged to the mark, Britain had to follow. High interest rates in a recession. It was economic suicide.

Speculators smelled blood. George Soros and his Quantum Fund started building a massive position. He borrowed billions in pounds and sold them on the open market.

Other hedge funds piled in behind him. They were all betting on the same thing: Britain couldn't hold the line. The Bank of England fought back desperately.

They bought pounds with foreign currency reserves. Billions and billions of pounds. They raised interest rates from 10% to 12% in a single morning.

Then announced they'd go to 15%. The markets didn't flinch. Every pound the Bank of England bought, speculators sold two more.

By 7 PM, it was over. Chancellor Norman Lamont appeared before cameras. Britain was leaving the ERM.

The pound crashed 15% in hours. Soros made over $1 billion in a single day. He became known as "the man who broke the Bank of England." British taxpayers lost an estimated 3.4 billion pounds defending a doomed currency.

The day became known as Black Wednesday. A humiliation for the government. A triumph for speculators.

And a permanent reminder: When a currency peg doesn't match economic reality, no amount of reserves can save it. Markets always find the weakness. And they never show mercy.
