The Zambian monetary unit refers to the official currency used in Zambia. This unit is called the kwacha, and it has synonyms such as ZMW, Zambian kwacha, and Zambian dollar. The Zambian monetary unit has undergone significant changes, including the devaluation of the kwacha in the early 1990s, which saw its value plummet by 75%. In 2012, the Bank of Zambia redenominated the unit, which replaced 1,000 old kwachas with a single new kwacha. Despite these changes, the unit remains vital to Zambia's economy, and it is widely utilized in its daily transactions.
