The Zimbabwean dollar (sign: $, or Z$ to distinguish it from other dollar-denominated currencies) was the official currency of Zimbabwe from 1980 to 12 April 2009.
Although the dollar was considered to be among the highest-valued currency units when it was introduced in 1980 to replace the Rhodesian dollar at par, political turmoil and hyperinflation rapidly eroded the value of the Zimbabwe dollar to become one of the least valued currency units in the world, undergoing three redenominations, with high face value paper denominations including a $100 trillion banknote (1014). The third redenomination produced the "fourth dollar" (ZWL), which was worth 1 trillion ZWR (third dollar), or 1025 ZWD (first dollar).
Despite attempts to control inflation by legislation, and three redenominations (in 2006, 2008 and 2009), use of the Zimbabwean dollar as an official currency was effectively abandoned on 12 April 2009. This was a result of the Reserve Bank of Zimbabwe legalising use of foreign currencies for transactions in January 2009.
Currencies such as the South African rand, Botswana pula, pound sterling, euro, and the United States dollar are now used for all transactions in Zimbabwe; the policy of the government of Zimbabwe has insisted that any attempts to reintroduce Zimbabwean currency should be considered only if industrial output improves.
