As a Brazilian, the whole concept of "overdraft fees" feels truly alien.

I am not aware of any banks that will charge you like that and wouldn't be surprised if it were forbidden by the central bank. Some of them will even charge you nothing even if the account sits in the negative for a set number of days (10 usually). The others will just charge as if it were a loan, by the month's end.

Now, here is the interesting part. You can expect to pay, currently, over 10% per month on any outstanding loans. In the case of a negative balance, charges upwards of 30% are common. So it's not like they aren't robbing people either. They are just doing it in a less visible way.
