In the summer of 1946 inflation in Hungary reached 41.9 quadrillion per cent. That’s 41.9 followed by 14 zeros – the highest rate of inflation ever recorded anywhere in the world. It meant prices of everyday goods and services doubled, on average, every 15 hours. As the shattered country struggled to get to its feet after World War Two, weighed down by a Soviet occupation and punishing reparations, its government had little choice but to print more and more money, further fuelling the price spiral. The hyperinflation stripped wages of almost all their value and plunged millions of Hungarians into a new fight for survival, but as they lost all faith in banknotes they turned to ever more inventive ways to trade and earn a living. We discuss how life for ordinary Hungarians changed amidst the chaos, what caused and eventually halted the economic disaster, and what the whole episode can tell us about the meaning of money.
