and central banks with the expansion of credit.

Banks expand credit well beyond their own assets and by the funds of their clients, often supported or encouraged by the setting of low interest rates by a central bank. This additional credit flow into the economy from increased borrowing for capital projects stimulates economic activity. Projects which would not have been started before, seem now profitable, creating malinvestment. They increase demand for production materials and for labor and their prices rise, which, in turn, leads to an increase in prices of consumption goods. If the banks would stop the extension of credit, the boom would be rapidly over. To prevent the sudden halt of this boom (and the resulting collapse of prices), the banks must create more and more credit, and the prices will rise even more.
But this expansion of credit cannot continue forever. There is no additional capital or labor; there is only more money (and debt). The means of production and labor which have been diverted to the new enterprises have to be taken away from others. Society is not sufficiently rich to permit the creation of new enterprises without taking away from others. As long as the expansion of credit is continued this will not be noticed, but it can't be pushed indefinitely. The inflation and the boom can last only as long as the public thinks that the prices will stop rising in the near future. When the public becomes aware, that there the inflation will not end, and that prices will continue to rise, panic sets in. Eventually, people may give up the currency and rush to exchange money for goods, buying things they have no use for, just in order to get rid of the money (the so-called "flight into real values.")
