Offshore US Dollar deposits (could also credit denominated in USD created by credible non-us banks) held in banks outside the US are up to a record ~$14.5 trillion. compared $4.5T in 2000.
By comparison, only ~$3.5 trillion worth of euros are held in offshore banks, outside the Eurozone.
This means offshore US Dollar deposits are now equivalent to~43% of US domestic bank deposits, with no other currency coming close to this percentage.
Fed has no control on this so far. but has full control blockchain stablecoins.
