The Ibovespa rose 0.6% to close at 142,145 on Wednesday as Congress rushed to vote on a bill replacing a proposed IOF hike, preserving exemptions for incentivized securities and unifying income tax on fixed-income at 18%. Stock exchange operator B3 led the rise adding 3.5%, followed by Raia Drogasil up 3.1%, Vibra rising 2.2%, and Ultrapar Participaco surging 5.5%. Miners and steelmakers also advanced (Vale 0.8%, Gerdau 2%). Petrobras slipped 1% despite recent contracts and Argentine gas imports that support medium-term cash flow.
