If the financial crisis comes back some day
As in 2008 after the Lehman Brothers incident
I think it will be quite a burden to do the currency policy QE again.
The crisis of the financial enterprise caused the fault
In spite of quantitative easing to overcome the crisis, most people do not feel that they have improved economically, but rather feel they have benefited from the huge banking system
Again, if the financial crisis recurs, it would be unreasonable to write monetary policy against the fierce opposition of many who question the effectiveness of QE
Government policies will try to stop the economic downturn by lowering interest rates and introducing negative interest rates.
Depositors will be burdened with the deposit fee, which is a negative interest rate, and they will prefer the currency.
If the central bank issues the Central Bank Digital (crypto) Currency along with the private cryptographic currency, then the Digital Currency that replaces the current dollar, the dollar, will appear and settle
If so,
global currency redenomination
Whether or not the financial crisis comes
In an economy where only Fiat Money (currency) is used, private cryptographic and central bank digital currencies will be issued and coexist
