Group of 10 Early 1900's WWI German Hyperinflation Notes. hyperinflation in the Weimar Republic, economic disaster in the Weimar Republic in 1922–23 that impoverished millions of German citizens.During World War I, prices in Germany had doubled, but that was just the start of the country’s economic troubles. The new German Weimar government was bound by the Treaty of Versailles, which was designed to ensure that the grandees of the now defunct German Empire could never wage war on their neighbours again. The treaty’s terms put the Weimar government under significant financial pressure, such that it was unlikely that the ailing German economy would recover. The huge amount the Germans had to pay the Allies in reparation for the war meant they couldn’t afford to buy imported goods, and the loss of their colonies meant they couldn’t rely on cheap raw materials. At the same time, billions of marks hoarded during the war suddenly came back into circulation.The rising cost of goods combined with a dramatic increase in the money supply created perfect conditions for inflation. Before World War I, the exchange rate was just over four marks to the U.S. dollar. By 1920 the value of the mark was 16 times less. It stabilized at 69 marks to the dollar for some months. The Weimar government was still in a position to get a grip on the economy; instead, it chose to print yet more money in order to pay the reparation debt. By July 1922 prices had risen by some 700 percent, and hyperinflation had arrived.
