In August 2018, Venezuela replaced the bolivar fuerte with the new bolivar soberano (above). One soberano was worth 100,000 fuertes.

Venezuela's beleagured currency was easily the most volatile in a year in which overall volatility increased at the highest rate since 2015.

Venezuela's currency was the most volatile in the world in 2018 as its complex, three-tiered currency system finally gave way to hyperinflation, a collapsing economy and the increased authoritarian rule of Nicholas Maduro.  The bolivar, as the currency is officially known, reached a volatility percentage of 39.8%, according to the Currency Volatility Index (CVI), the highest rate since Myanmar's currency reached a 43.3% level in 2012.
