How does the fractional reserve banking system impact the overall stability of the economy?

The fractional reserve banking system can impact the overall stability of the economy by potentially amplifying economic fluctuations. When banks create money through lending based on only a fraction of their reserves, it can lead to increased money supply and credit expansion. This can stimulate economic growth but also increase the risk of financial instability if loans are not repaid or if there is a sudden loss of confidence in the banking system.
