Pound to dollar exchange rate by year, 1940–1971
During the Bretton Woods era GBP/USD was an official parity, not a market price — so for most of these years a single figure holds for the whole year. That is why annual tables of this period look so flat.
| Years | Official GBP/USD parity | Note |
|---|---|---|
| 1940–1948 | $4.03 | Wartime and immediate post-war peg, set in 1940 and carried through the Bretton Woods agreement |
| Jan–Sep 1949 | $4.03 | Final months of the $4.03 parity, under mounting balance-of-payments pressure |
| 18 September 1949 | $4.03 → $2.80 | The Cripps devaluation — a 30.5% cut, announced on a Sunday and effective immediately |
| 1950–1963 | $2.80 | The $2.80 parity holds unchanged for eighteen years; annual averages differ only by fractions of a cent |
| 1964 | $2.80 | Sterling crisis under the new Labour government; the $2.80 Bretton Woods peg is defended rather than moved |
| 1965–Nov 1967 | $2.80 | Repeated defence of the parity through central-bank support operations |
| 18 November 1967 | $2.80 → $2.40 | The Wilson devaluation — a 14.3% cut, and the “pound in your pocket” broadcast |
| 1968–1971 | $2.40 | The final fixed parity, until the Bretton Woods system unravelled |
| 1972 onward | market-determined | Sterling floats on 23 June 1972; from here a “rate for the year” is an average, not a parity |
Why the fixed-era figures are so precise
Between 1940 and 1971 the pound-dollar rate was a policy decision. Under Bretton Woods each member country declared a par value against the US dollar and undertook to keep the market rate within a narrow band of it — one percent either side. The Bank of England enforced that band by buying and selling sterling out of the reserves. So when a source quotes “$2.80 in 1964”, it is quoting the declared parity, and the actual traded rate that year sat within roughly $2.78–$2.82.
This also explains why devaluations arrive as sudden steps rather than slides. A parity holds exactly until the government concludes it can no longer be defended, at which point it is moved overnight — $4.03 to $2.80 in September 1949, $2.80 to $2.40 in November 1967. Both were among the largest single-day moves in the pound’s history, and neither was a market event in the modern sense.
Where to find full annual series
For year-by-year averages across the whole period, the standard public sources are the Bank of England’s historical statistical database, the Federal Reserve’s H.10 series (which begins in 1971 for daily data), and university-hosted archives of annual average exchange rates. Figures in the table above are the official parities and the dates on which they changed; annual averages from those sources will differ slightly in devaluation years, because the year contains both parities.
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.
