The Johns Hopkins-Cato Institute Troubled Currencies Project
For various reasons – ranging from political mismanagement, 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. Its timely research made it the first to uncover and break the story of Iran’s flirtation with hyperinflation in 2012. It also determined that Venezuela became the world's 57th episode of hyperinflation in 2016. The data and estimates are updated on a regular basis and can be found at the following location: The Johns Hopkins-Cato Institute Troubled Currencies Project.
