The Ibovespa rose 0.4% to close at 187,423, recovering from earlier losses as investors responded to prospects for talks between the United States and Iran. US President Trump said US officials had a "very good" meeting with Iranian envoys at the UN General Assembly and that another meeting was planned. A senior Iranian official said Iran could reopen the Strait of Hormuz within days if the United States eased military pressure and lifted its blockade on Iranian ports. The pullback in oil prices supported equities. Banks traded unevenly: BB fell 1.4% and Santander declined 0.6%, while Bradesco gained 1.5% and Itaú rose 0.2%. Petrobras added 0.7% despite lower oil prices. Vale advanced 0.4% after confirming its acquisition of a 30% stake in Ligga, while Axia rose 1.3%. The index remained volatile after Copom (Brazil's monetary policy committee) released somewhat hawkish minutes.
