IMO the de-dollarisation of trade transactions within the BRICS and to a lesser extent within ASEAN will weaken the USD as the global reserve currency and the US ability to print Trillions of Greenbacks to support overseas wars including that of the Ukraine .
The Ukraine War and subsequent comprehensive economic sanctions on Russia by NATO members generally and the US specifically has sent a shot over the bows of emerging economies who fear the "$Russian & Iranian" treatment by US Neo-Cons should these emerging economies object to getting into bed with Uncle Sam.
