Yes, but he only can do that to American companies/companies that do business here. He can't tell, say, the Swiss to keep the Russians' money.

There's a difference between "Money market funds, banks, stock exchanges, and every other financial institution can be frozen instantaneously by the U.S. President to 'prevent another financial collapse'" as thread OP mentioned and what you're talking about. I was addressing only systematic action for the sake of averting economic problems, not financial uses of national security power.

For INDIVIDUALS, you're absolutely correct.

Which is why I'm a large proponent of local currencies.

(Trust me, I understand. I'm a very confused Ukranian-American who would like to go back to not being relevant.)

Ok thanks for repeating those details of the GP comment. I have to agree with you that some facts in there are fundamentally wrong. The U.S. government can do things to restrict uses of USD but they aren’t _that_ arbitrary.
