"Nowadays, serious alternatives to the US$ for the purpose of world trade are being mooted but aren't yet in place..'"
Lol.
Which "serious" alternatives are these?
The Euro? The Yen? The British Pound? One of the much-vaunted cryptocurrencies?
The US Fed printed something like two trillion dollars over the past 6 months, and yet the US currency is unchanged against other major currencies. If that doesn't teach us anything about the sheer resilience of the US dollar, then I'm not sure what will.
The global economic aftermath of this virus is going to - unavoidably - impact the US economy, but compared to other more trade exposed economies which are likely to be severely contracted, the US will come up smelling rosy by comparison.
I've spent most of my adult life (I'm no longer a youngster, mind) reading about, and listening to, foretellings of the imminent demise of the US dollar.
