Prices doubled every 15 hours in the worst hyperinflation ever recorded

In mid-1946, Hungary's currency collapsed so fast that prices doubled roughly every 15 hours, and the government issued a banknote worth 100 quintillion pengő. It remains the most extreme hyperinflation ever documented — worse than Weimar Germany or Zimbabwe — driven by war debts and reckless money printing.
