The big question as has been argued by Jim Rickards is not the printing of money rather it is the velocity of money or how quickly the money changes hands.
The great inflation fear arises as the world comes out of lock down and people start spending on holidays, restaurants overseas trips etc at a far more rapid rate than they do now.
The second part of the inflation question after lock down is --if the various Reserve banks attempt to prevent inflation then they must increase interest rates and withdraw currency.
If they increase interest rates then the interest bill on their debt and the respective Government Debts will increase dramatically thus there is a strong disincentive to increase interest beyond a nominal amount.
If they withdraw to much money through bond sales or increases in Taxes then an initial recovery may be reversed.
Governments and indeed many individuals and corporations are heavily exposed to debt thus they also will be damaged by increases in interest rates and taxes.
The balancing act facing Governments is now almost impossible thus perhaps covid 19 is the accelerator for a problem that has been brewing since 1971. The apparent solution is do anything possible to trigger inflation to reduce the real debt by returning to lenders dollars of less value so PM's and base commodities are probably the place to be for the next 3 or more years.
