For various reasons — ranging from political mismangement, to civil war, to economic sanctions — some countries are unable to maintain a stable domestic currency. These "troubled currencies" are associated with elevated rates of inflation, and in some extreme cases, hyperinflation. Often, it is difficult to obtain timely, reliable exchange-rate and inflation data for countries with troubled currencies.
To address this, the Troubled Currencies Project collects black-market exchange-rate data for these troubled currencies and estimates the implied inflation rates for each country.
