This is inflation that is rapid or out of control. It usually only occurs during wars or during severe political instability.
Hyperinflation is a continuous rise in the price level, which makes it impossible for people to save money, because of its constant loss of value. Prices increase as the currency loses its real value so the population has a clear reduction in its monetary wealth.
It affects the companies and business capital, and even our personal own, because it implies its decrease and loss in a considerable way.
This is one of the economy's most feared enemies.
