According to representatives of the Bank, the issue of the BNDES coin will help restore public confidence in the state banks of Brazil, which are often criticized because of corruption scandals.
First of all, many stable coins work on ETH network, USDT and GUSD are part of that list.
Second, a stable coin is just as centralized as fiat and you have to trust the issuer they'll do all the needed things to keep the price stable.
Now, with such silly politicianistic nonsense as in the quoted text, I would clearly stay away from this coin (even more than the other stable coins).
