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
