Staying in a western controlled financial system is also a risk. Look at what happened to Russia after their invasion of Ukraine. If the system works out, there will probably be alot of other countries interested in either switching over, or playing both sides.
There be two systems and countries, companies can use both. Right now there is a monopoly but there can be a multitude of systems.
Russia’s importance has been diminishing exponentially. Their greatest exports have all become less valuable (their military technology has shown up to be below par, their gas pipelines to Europe are basically done for, their most valuable human capital has fled/died in the millions).
Brazil is in economic crisis. Again their economy has been becoming less important rather than more over the past 5-10 years.
And the less said about the South African economic disaster the better.
India and China also hate each other and are literally fighting an active war with each other as we speak.
BRICS as an organization is terribly impotent considering how important 2 of their 5 largest members are in the world order.
Also, it’s nice for Switzerland that they have SWIFT but it’s really not that useful. We learnt that when SWIFT detonated the nuclear option a couple of years ago against Russia and nothing happened.
Clearly SWIFT has little geopolitical value, so with that known now, even western economies will benefit with some competition.
