Honestly, this would be a decent way to just hit the reset button on the world. You have a magic supply of infinite money? Fuck it, everyone is a billionaire now, in every single currency. Sure, billionaires might try to leverage hard assets instead of liquid cash, but that’ll only get them so far when anyone can just buy their billion dollar business out from underneath them. The short term fallout would be hyperinflation of mythic proportions, and global pandemonium. Long term, we may actually see some socialist change in regards to the fact that money is largely useless now.
