During the height of inflation from 2008 to 2009, it was difficult to measure Zimbabwe’s hyperinflation because the government of Zimbabwe stopped filing official inflation statistics. The black market exchange rate to the US dollar changed constantly. In 2008 innovative locals adopted ‘The Hard Boiled Egg Index’ to determine a fair value of exchange rate. The Hard Boiled Egg Index works on the premise that across Africa, US$1 buys around seven hard boiled eggs. Hard boiled eggs are sold on the side of the road as a snack.
