Brazilian real strength in early October 2026 stems primarily from presidential election dynamics, with runoff polls showing Senator Flávio Bolsonaro ahead of President Lula and signaling potential fiscal restraint that has narrowed risk premiums. USD/BRL traded near 4.98–5.02 after dipping below 5.00, supported by robust job creation and a wide Selic–Fed funds differential near 1,000 basis points that sustains carry flows, even as Copom has eased to 13.5%. Rising IPCA projections near 5% for 2026, resilient U.S. data keeping Treasury yields firm, and DXY around 102 create counterpressure, while market consensus holds end-2026 USD/BRL near 5.20 amid ongoing volatility from the October 25 runoff and upcoming inflation prints.
