The British Pound from a sound-money lens
Oldest still-circulating currency. Bank of England (1694) — and a 99% loss since.
The pound sterling traces its design back to 1158 and its name to Anglo-Saxon silver pennies, which makes it — at over 850 years — the world's oldest still-circulating currency. The Bank of England, founded in 1694, is the second-oldest central bank on this page. None of which has prevented the pound from losing nearly all its purchasing power over the modern monetary era.
A 1900 pound bought what about £140 buys today — a 99% loss across the century. The pace accelerated after 1971 (the abandonment of Bretton Woods) and again after 2008 (the Bank of England's first quantitative easing programme). M4 broad money roughly tripled between 2000 and 2024.
The pound's defining moment of recent years was the September 2022 mini-budget crisis: a fiscal package the gilt market rejected forced £65bn of emergency BOE bond-buying and a 7% intraday currency drop. It was a reminder that even reserve-currency status doesn't insulate a fiat from fiscal credibility shocks.
CPI inflation peaked at 11.1% in October 2022 — the highest in 41 years — before easing back to the BOE's 2% target. The structural pressures haven't gone away: an aging population, rising debt-to-GDP, and a Bank balance sheet still well above pre-crisis norms. The pound's institutional credibility (rule of law, an independent central bank, deep gilt markets) remains real. Its monetary credibility — its ability to hold value over decades — is on the same trajectory as every other fiat on this list.
