If you were to ask most people which country suffered the worst inflation in history, they would answer Germany, since Germany’s hyperinflation after World War I is probably the most famous. By 1923 when Germany finally put an end to its hyperinflation, it took 1 trillion old Marks to get 1 new Rentenmark. As devastating as the German inflation was, there were three hyperinflations that made the German case look amateurish: Hungary in 1946, Yugoslavia in 1992-1993 and Zimbabwe from 2004 to 2009. Of these three, Hungary’s was the worst of them all.
Hungary was no stranger to hyperinflation. The Austro-Hungarian Empire was on the losing side of World War I and was broken up after the war. The new nation of Hungary lacked the proper government structures, so it turned to printing money to fill the hole in its budget. Before World War I, there were 5 Kronen to the US Dollar, but by 1924 there were 70,000 Kronen to the US Dollar. So Hungary replaced the Kronen with Pengö at the rate of 12,500 Pengö to the Kronen in 1926.
