The gold-standard era: sterling on top
For roughly a century before the First World War, the pound was the world’s dominant currency and was fixed against the dollar near $4.86 under the classical gold standard. London was the centre of global finance, and a large share of world trade was invoiced and settled in sterling. The pound of that era was, in effect, what the dollar is today.
War, decline and devaluations
The two world wars transformed the picture. Britain went from creditor to debtor, the United States emerged as the dominant economic and financial power, and the dollar steadily displaced sterling as the world’s reserve currency. The pound was pegged at $4.03 during and after WWII, then devalued to $2.80 in 1949, and devalued again to $2.40 in 1967 — the episode that produced Harold Wilson’s famous (and much-criticised) reassurance about “the pound in your pocket”. Each step reflected the strain of defending an overvalued fixed rate against persistent balance-of-payments deficits.
The floating era begins
When the Bretton Woods system of fixed exchange rates collapsed in the early 1970s, GBP/USD began to float freely, its value set by the market rather than by decree. The pound fell heavily in the mid-1970s amid high inflation and an IMF bailout, then swung dramatically in the 1980s. In February 1985 a soaring dollar drove Cable to a then-record low of about $1.05, before the dollar reversed sharply following the Plaza Accord.
Black Wednesday to the modern era
In 1992, Britain’s attempt to shadow European currencies inside the Exchange Rate Mechanism ended on Black Wednesday, when speculative pressure forced the pound out of the ERM in a single dramatic day. The pound later staged a long recovery, reaching a multi-decade high around $2.11 in 2007 before the global financial crisis sent it sharply lower. The 2016 Brexit referendum triggered the largest one-day fall in decades, and in September 2022 the pound hit a record intraday low near $1.035 after an unfunded package of tax cuts — the “mini-budget” — spooked markets, briefly reviving talk of pound-dollar parity.
The through-line of this history is the long handover of financial leadership from London to New York, overlaid with the UK’s recurring struggles with inflation, deficits and confidence. Today GBP/USD trades freely as one of the most liquid pairs in the world, its level set minute by minute by the same forces — rates, inflation, growth and risk — described across this site.
