Interesting story but it’s also talking about how inflation was at 80% in Brazil in the 1980s, because they were printing money. What they did in 1993 with the URVs is a fascinating psychological experiment, but I’m not sure if it was the critical factor in stopping inflation. As per the article

It wasn’t the only trick, obviously. While they put URVs in place, the group of economists made the government balance its budget and slow down on money creation.

So I feel like it was basic economic policy that mostly worked, rather than printing money and trying to dictate its value.
