Hungary (1946) 100 Quintillion Pengo

....... (100,000,000,000,000,000,000, or 1020). The Post-WWII hyperinflation of Hungary holds the record for the most extreme monthly inflation rate ever — 41,900,000,000,000,000% (4.19 × 1016%) for July, 1946, amounting to prices doubling every fifteen hours!!

The pengo (sometimes written as pengo or pengoe in English) was the currency of Hungary between 1 January 1927, when it replaced the korona, and 31 July 1946, when it was replaced by the forint. The pengo was subdivided into 100 filler. Although the introduction of the pengo was part of a post-World War I stabilisation program, the currency survived only for 20 years and experienced the most serious hyperinflation ever recorded.
