Genuine Zimbabwe 2008 Reserve Bank of Zimbabwe $10,000,000,000 Note (Ten Billion Dollars)

Until early 2009, the Reserve Bank of Zimbabwe (RBZ) routinely printed money to fund their budget deficit, causing hyperinflation.

Dollarization in early 2009 - which allowed currencies such as the Botswana pula, the South Africa rand, and the US dollar to be used locally - ended hyperinflation and reduced inflation below 10% per year.
