Recent Brazilian presidential election developments, including a tight Oct 25 runoff between candidates favoring varying degrees of fiscal discipline, represent the dominant near-term driver of USD/BRL sentiment. The pair has traded near 4.99–5.01 in early October 2026 after appreciating from a December 2025 peak above 5.57, supported by Brazil’s elevated Selic rate near 13.75% and a wide interest-rate differential versus the Fed funds range. September inflation at 4.58% y/y exceeded the 4.5% target ceiling, while commodity prices and external accounts provide structural support. Traders are pricing in potential post-election volatility tied to fiscal outlook and any Fed policy adjustments, with the BRL’s carry advantage tempering broader dollar strength.
