English: The value of one US dollar in Venezuelan bolívares (VEF/VES) on the black market through time, according to DolarToday.com. Blue vertical lines represent every time the currency has lost 90% of its value relative to the US dollar since the last one. This has happened four times since 2012, meaning that the currency is worth, as of December 2017, less than one ten-thousandth of what it was worth five years ago, since it has lost 99.99% of its value. The rate at which the value is lost (inflation) is rapidly accelerating. The first time the money took 2 years and 2 months (an implied monthly inflation rate of 9.3%) to lose 90% of its value, the second time 1 year and 10 months (implied rate 11% m/m), the third time only 10 months (implied rate 26% m/m), and the fourth time a mere four months (implied rate 77% m/m).
