This work inquiries the impact of high inflation, or hyperinflation, on the economy of a country. Its causes and the actions of the government are being inquired that can stabilize but also worsen this inflationary process and thereby completely damage the economy of a country. Furthermore, the consequences that this economic phenomenon leaves on the state, especially on its economic growth, as well as the stabilization policies that are most often used to suppress hyperinflation, are emphasized. Special emphasis is placed on the most severe recorded case of hyperinflation so far, which is the case of Hungary from 1945 to 1946. It is significant and worth noting because in this case the prices doubled every fifteen hours, and the consequences of hyperinflation were catastrophic. This case shows that in addition to the increased amount of money in circulation, hyperinflation is due to a large lack of supply of goods and goods, i.e. a consequence of a supply shock. The purpose of the work is to investigate the historical circumstances of hyperinflation, the causes that led to it, the actions of the government at the time, as well as ways to stabilize this advanced inflation, and to prove on a practical example that uncontrolled money printing is not a solution to hyperinflation. This work shows how stabilization is possible without foreign loans, by introducing a new value using internal policy and own funds. Furthermore, monetary policy does not mean only the change of value but the entire creation and circulation of money, and the stabilization of value is important in order to ensure the stability of the internal price level. The Hungarian economy, despite hyperinflation, managed to recover after the Second World War, and stabilization policies to combat hyperinflation have been shown to trigger economic recovery and growth and thus contribute to the country's economic progress.
