Venezuela’s bolivar is collapsing. And as night follows day, Venezuela’s annual implied inflation rate is soaring. Last week, the annual inflation rate broke through the 500% level. It now stands at 510%. When inflation rates are elevated, standard economic theory and reliable empirical techniques allow us to produce accurate inflation estimates. With free market exchange-rate data (usually black-market data), the inflation rate can be calculated.
