Reality Check - when the US Dollar is dropped as the Global Reserve Currency - there will quit being a Global Reserve Currency.
That will wreck havoc on Global Trade.
Not among countries that agree on a common currency or a currency back by commodities like gold or oil, the BRICS are a prime example of what can happen, the US Dollar will stone a major currency but it won’t be dominant and we won’t be able to use it as a political weapon to impose sanctions on anyone
It also means we become Venezuela with nukes…….Overnight. RIP America.
