Brazil's Bovespa Index (BMFBOVESPA:IBOV) climbed 0.71% on Monday, moving close to the 207,000 mark as market participants evaluated the first Sunday night presidential debate between President Lula and Senator Flávio Bolsonaro. Fresh election polling released on Monday by BTG/Nexus and AtlasIntel showed rising support for Lula and a drop in voting intention for Bolsonaro, though Bolsonaro maintained his lead in both surveys. The BTG/Nexus survey indicated a statistical tie, whereas the AtlasIntel poll placed Bolsonaro's advantage outside the margin of error.

The market reaction reflects investor preferences regarding fiscal policy. Although Senator Bolsonaro has not yet outlined explicit policy proposals, financial markets generally perceive him as more likely to implement government spending cuts and broader fiscal reforms. Investors consider such fiscal discipline essential for bringing down interest rates. Broad gains across key market sectors supported the index, led by financial firms such as Itaú, Itaúsa, and Banco do Brasil (BB), which each advanced roughly 1%. Utility operator Axia also gained over 1%, while healthcare provider Rede D'Or climbed 2% and aircraft manufacturer Embraer added 1%. Conversely, oil producer Petrobras fell 1% as crude oil price gains lost momentum.

Moving forward, market participants will monitor forthcoming presidential debate performances, updated polling data, and further candidate policy announcements. Key developments regarding fiscal reform proposals and economic plans will remain pivotal for Brazilian equity valuations and interest rate expectations.
