The Brazilian presidential runoff on October 25 between Flávio Bolsonaro and incumbent Luiz Inácio Lula da Silva remains the dominant near-term driver of USD/BRL sentiment, with polls showing a tight race that markets interpret as favoring fiscal consolidation and deregulation under a potential Bolsonaro victory. The pair trades near 5.03 as of mid-October 2026 after touching a 2026 high of 5.54 early in the year and a low of 4.88 in May, reflecting an 8.5% year-to-date decline amid elevated Selic rates and commodity support for the real. Analysts at Goldman Sachs and JPMorgan have revised forecasts lower toward 4.70–4.80 by year-end, citing narrowing fiscal risk premia and carry-trade appeal, though global dollar strength, Fed policy signals, and any post-election slippage on debt dynamics could push volatility higher. Key upcoming catalysts include runoff results, subsequent policy announcements, and fourth-quarter inflation and growth data that will shape monetary easing expectations.
