If you go to BACEN you can look for yourself to get the historic data on inflation and SELIC interest rates. FHC was able to both have high interest rates, high inflation rate and a broken economy (or did you forget that brazil had to ask IMF for a huge money lend?)...

I don't know what you mean by a coupe... but it is well known that FHC paid congress men to pass the law allowing him to be re-elected. Curiosly, now they think re-election is bad... go figure.
