Stable coins can print anytime they want, there's no one at the SEC that will regulate it in this admin. As a matter of fact it's pretty well accepted in some circles, especially on subreddits, that Tether did exactly that, printed usdt, purchased btc at effectively 0 cost basis, inflating bitcoin prices by decreasing supply and then turned around and purchased treasuries. Cantor Fitzgerald ran that for them.

Further, stable coins / crypto are almost certainly being used to slop up as much liquidity as possible and has essentially so far pulled 4 trillion out of circulation. If not for that sleight of hand trick, hyperinflation, at least in the USA, would have already happened. Probably still will as there's only so much can kicking that can occur. I know of 30 year olds that literally live in mom's basement and dump nearly all of their just above minimum wage checks straight into Robinhood to blindly purchase crypto. Will forever beat inflation is the mentality.

Sure looks like there's going to be lots of pain for poor and middle class people in the next 5 years.
