world will go full in to usa dollar standard
Sure... Now tell that to all those BRICS countries that they'll all go bankrupt and back to USD. You're funny.
These predictions were made back in 2020. Now it’s already 2024, but nothing bad is happening with the currencies you specified and I’m sure that it won’t happen. In order for the currencies of these states to disappear, it is necessary that these states themselves disappear or they unite following the example of the European Union. Now almost all states and their currencies are going through difficult times. But this does not mean that they or their currencies will disappear soon.
To defend OP, Pound has been bleeding against the Dollar for more than 10 years. It used to be worth $2 and now it's only $1.27, so it looks like it continues to weaken and the historical bottom is somewhere at 1.2 USD. If we fall below this it's going to look bad.
Anyway, all fiat currencies look weak and with BRICS I just don't see how USA could take over the world with their currency. IMO Dollar is at its global peak and can either hold the status or weaken and there are countries actively working to do the latter.
