Brazil hyperinflation case is a great read, both on the instruments that appeared to take advantage of it (and ultimately put more gas on the fire) and also on how Brazil managed to tackle it (it was more a behavior science thing than economics).

Interesting things that I remember from that time:
- Hypermarkets made a boom, because people would make big monthly groceries purchases right when they got their salaries, and avoid small frequent purchases (as the money would lose value with time, very quickly)
- Price freezes were very frequent and very ineffective as companies would simply stop producing/selling, generating product shortages everywhere.
- A financial device called Overnight, were you would convert your brazilian currency (had many names) into USD at night and then convert it back to BR on the next day
- Government would try to control USD exchange rates and this simply created a black market that got so widespread that the black market (called "parallel market") had its rates published at newspaper and TV like a normal thing.
