How did you come to the 300T? Back when I looked into this I found around 45T (by just adding M0, M1, M2, and physical cash) [1]. Note that the numbers are from march 2021. The large difference with your number makes me suspect I’m missing something
Not really, since USD in the international currency of exchange, and every country needs to have reserves in dollars in order to purchase things like petrol and gas - so in effect every other currency tries to align to the dollar, for better or worse.
