Ending hyperinflation depends on which model is the main cause. In the confidence model, the method of ending hyperinflation is to change the backing of the currency—often by issuing a completely new one. Also, if possible, any action that restores confidence in the government can help end the hyperinflation (e.g. the psychological effect of food in the shops after shortages in most hyperinflations, the election of a new government both capable of and dedicated to tackling the problem). In the monetary model, the issuer of the currency must stop expanding the currency.
