"Hyperinflation typically occurs when several forces combine into a worst-case scenario. Ingredients often include corrupt governments, unstable economies and poor monetary policies. Natural events can also play a role, like long-term droughts that reduce a country’s ability to produce goods or feed itself.
Increasing money supply
One of the most common direct causes of hyperinflation is when a central bank prints too much money. Historically, this occurs when struggling governments need to pay off large debts or fund wars.
As more funds become available, the value of each unit declines and prices rise. Consumers are forced to spend more on the same goods and services as company profits decline. To keep abreast of rising prices, the central bank may kick up production further, feeding into the cycle."
