Brazilian markets and the Superior Electoral Court (TSE) have faced ongoing volatility driven by economic shifts and judicial disputes. In late August 2026, the U.S. dollar rose toward R$ 5.20 following hawkish signals from Federal Reserve President Kevin Warsh. By mid-September, economic data showed 0.32% deflation in August, fueling expectations for interest rate cuts. The TSE also faced scrutiny over digital communication; on 14 October, TSE President Kassio Nunes Marques ordered the restoration of the ‘Exército do Lula’ WhatsApp channel after its official registration, following a ruling by Electoral Corregedor Ricardo Villas Bôas Cueva that a previous deactivation was ‘disproportionate’. Leading up to the presidential runoff, markets showed caution. On 23 October, the U.S. dollar fell to R$ 4.993, its lowest level since 9 October, while the Ibovespa rose 0.47%. Analysts at Goldman Sachs noted that while the real had potential for appreciation, fiscal uncertainties and the tight race increased volatility risks, suggesting a Lula reelection might trigger market corrections. Following the election, markets reacted sharply to Lula’s re-election, as he secured approximately 51.8% of the vote against Senator Flávio Bolsonaro’s 48.2%. ~~Prior to the final results, markets experienced a rally on 19 October, with the~~ The Ibovespa ~~rising 1.57% to 208,295.98 points.

By the end of October, the downturn intensified. The U.S. dollar rose to R$ 5.446, its highest closing value of the year and its largest weekly gain since 2008, following a 9.15% weekly increase. Simultaneously, the Ibovespa fell 0.75% on the final Friday of the month, completing an 18.12% weekly decline, its worst weekly performance since March 2020. This decline was driven by domestic uncertainty regarding President Lula’s fiscal policies, economic team composition, and a net withdrawal of nearly R$ 7.6 billion in foreign resources from the secondary equity market. Government bonds via the Tesouro Direto program also saw significant devaluations: the Tesouro IPCA+ 2050 dropped 17.19%, while the Tesouro IPCA+ 2040 fell 11.99%. Interest rates for various securities rose above levels recorded prior to the October 4 vote.
