The most visible of these is Zimbabwe's recent currency 'revaluation.' The revaluation wiped three zeroes off the $ 20.000 Zimbabwean bill into a $20 bill. The local currency had been rendered almost worthless by years of inflation that hit 1,200 percent a year. Zimbabweans had to carry large satchels full of banknotes to pay for even the most ordinary trifle. The $20 bill actual value after the redenomination—10 American cents at official rates, less than 3 cents at black-market rates—remained unchanged. So has hyperinflation.
