What is a monetary crash?

We use the term "monetary crash" for a situation where an excessive supply of money leads to a loss of value of money, simply because economic agents lose confidence in money and try to protect themselves against such a loss . The quantity of money obviously remains unchanged, but the same quantity of money buy s a smaller quantity of safe-haven assets, such as: Real estate; Corporate capital; Private currencies (Bitcoin, etc.); Gold and other precious metals. This is a dangerous situation for the economy, because all economic agents holding money are impoverished by this loss of value of money and because money creation no longer stimulates the real economy, but simply raises the prices of safe-haven assets (lowers the value of money even further).
