It's a very nice distillation of the MMT account of money creation, which is descriptively accurate. 1/

One can argue the description is chosen to emphasize lack of constraint, but one can't really argue with the core point, that as issuer the US can spend US dollars in arbitrary quantities into existence, the whole bond apparatus is a way of extra providing services and/or managing consequences. 2/

He does make claims toward about the uniqueness of the dollar in the global system, suggesting continuing resilience of demand for dollars as a trade and reserve currency. 3/

Those have always been contestable, and I think are more contestable now than before due to the US "weaponizing" dollar dominance with sanctions and freezes, and more recently Trump's erratic attitude toward the dollar, access to the dollar system, and trade. 4/

But the account is clear and correct that if there were a crisis because the dollar lost its near universal acceptability in global trade, at a high value in terms of tradable goods + services, we'd experience that in prices, an inflation crisis rather than an inability to come up with dollars. 5/

(A sufficiently bad inflation crisis wouldn't necessarily be a gentler crisis that the sovereign defaults that countries that borrow in foreign countries are sometimes forced into, however. Russia once chose to default on its own debt, preferring that to the consequences of printing.) /fin
