Given that all major economies currently have a central bank supporting the private banking system, almost all new money is supplied into the economy by way of bank-created credit (or debt). Austrian economists believe that this bank-created credit growth (which forms the bulk of the money supply) sets off and creates volatile business cycles and maintain that this “wave-like” or “boomerang” effect on economic activity is one of the most damaging effects of monetary inflation.
According to the Austrian Business Cycle Theory, it is the central bank’s policy of ineffectually attempting to control the complex multi-faceted ever-evolving market economy that creates volatile credit cycles or business cycles. By the central bank artificially “stimulating” the economy with artificially low interest rates (thereby creating excessive increases in the money supply), the bank itself induces inflation (often focused in asset or commodity markets) and speculative investment, resulting in “false signals” going out to the market place, in turn resulting in clusters of malinvestments, and the artificial lowering of the returns on savings, which eventually causes the malinvestments to be liquidated as they inevitably show their underlying unprofitability and unsustainability…
