The hegemony of the dollar is likely to collapse due to the continued dedollarization by countries that do not benefit, especially those that are already members of the BRICS, this move will narrow the Dollar as a global reserve currency, a bad step to maintain the power of the Dollar is to use militarization to countries that threaten its sovereignty, but there is a possibility that a second step that is one of the options for the US to manage global finance is to go further into the digitalization of the currency, they will definitely build technology companies which sustains the development of an era like crypto currency, therefore it is very likely that they will take a position in the crypto industry for where people keep money and they will still have global financial power by using crypto.
They will do the same by using crypto. IMO
I'm still thinking about this, please share your opinion.
The de-dollarization is not a sprint but a marathon. The US and it's allies still dominate the global financial system so it will be a gradual process. But some champions of the process which includes the BRICS+ nations are implementing diverse mechanisms which include using local currencies for transborder trade thereby reducing the reliance on the Dollar.
Besides Russia, there are no other top BRICS+ nations that are fighting a war. Maybe it might happen in the future, who knows.
Even if these nations adopt crypto currencies as an alternative it will be centralized. The recent BRICS summit brought about the introduction of central bank digital currency (CBDC) called m-Bridge. For now these nations should focus on devising means of avoiding using the dollars for cross-border bank claims and also adopt other assets or currency as reserves.
