The Economist - Zimbabwe after hyperinflation: In dollars they trust < 5min

Grubby greenbacks, dear credit, full shops and empty factories … Inflation reached an absurd 231,000,000% in the summer of 2008. Output measured in dollars had halved in barely a decade. A hundred-trillion-dollar note was made ready for circulation, but no sane tradesman would accept local banknotes. A ban on foreign-currency trading was lifted in January 2009. By then the American dollar had become Zimbabwe’s main currency, a position it still holds today. … Zimbabwe’s dollar had been too liberally printed: a swollen stock of local banknotes was chasing a diminished supply of goods. Now the American banknotes the economy relies on have to be begged, borrowed or earned. Even so, the monetary system works surprisingly well. A scarcity of greenbacks keeps inflation in the low single digits. The economy has made up much lost ground.
