For example, – which publishes reliable black-market exchange rate data, as well as the Johns Hopkins-Cato Institute annual inflation estimates – claims that the bolivar has depreciated by over 100 percent this month. This is wrong because DolarToday’s arithmetic is wrong. DolarToday’s mistake represents a common error. It fails to transform the bolivar-U.S. dollar exchange rate into dollars and cents. At the start of the month, the VEF/USD black market rate was 1,501.17, and as of November 29th, it was 3,744.52.

The accompanying charts illustrate the correct arithmetic and the linkage between black market exchange rates and annual inflation rates. For Venezuela’s inflation to hit the International Monetary Fund’s (IMF) 720 percent inflation forecast for 2016, the bolivar would need …read more
