No, it’s like 1/3 foreign, 1/3 domestic, 1/3 the Fed and other money moving between federal agencies.
Presumably the latter would be a wash. Then of the domestic holdings, a big chunk is state and city holdings. Institutional
investors would be mad. Citizens with saving bonds and/or money tied up in t-bills thanks to reddit are a tiny fraction.
Even still, if we assume that the fed is a wash, that suggests that half of the remainder is domestic. I don't think that the orange idiot would start nuking the US. Oh god, I really hope that he's not quite that stupid.
I would really hope that Trump doesn't start nuking the US.
