Now, why should I trust Tombini's words this time around?
Because (i) his scenario for economic activity has been confirmed, 1% first quarter IBCBR; and (ii) his inflation forecast proved wrong: long run expectations rose and short-term CPI surprised everyone on the upside. So even if Tombini cares more about y than about pi, he should hasten the pace.
Well, I still have my doubts. I think Tombini does want to tighten faster, but if GDP figures put Dilma in dire straits, I guess she will dial the CB number and, very politely, order him to shut the fuck up.
