Prediction markets had put Bolsonaro’s odds near 80%. Chile and Colombia set rates and Mexico reports GDP.
The price tag on Sunday’s surprise landed fast. November futures for the Brazilian real were down 10% in Asian hours while the Nomura NF Ibovespa Link ETF, a Tokyo-listed Brazilian stock fund, plunged about 15%.

In premarket New York trading Monday, the damage was worse: Petrobras plunged roughly 22%, Itaú Unibanco, Banco Bradesco and Nu fell between 23% and 29%, while Vale lost 3.6%. EWZ, the main US vehicle for Brazilian equities, was off more than 18% before the open.
The loss is not just a Brazil story. It is also a read on a region.
What the Upset Means for Latin America
Luiz Inácio Lula da Silva won a fourth, non-consecutive term as Brazil’s president, defeating Senator Flávio Bolsonaro in Sunday’s runoff with 51.79% of the valid votes against 48.21%.
This is a reversal of first-round momentum: Flávio Bolsonaro led the October 4 first round, and Lula’s runoff win marked the first time since Brazil’s military dictatorship ended in 1985 that the second-highest vote-getter in the first round went on to win the presidency.
Brazilian voters denied Latin America’s resurgent right its ultimate prize, snapping a streak of seven straight conservative presidential victories in 18 months. Right-wing candidates allied with or favored by US President Donald Trump had won in Argentina, Chile, Colombia and Peru. Lula’s win keeps the region’s two most populous nations, Brazil and Mexico, under left-of-center leadership. That is not an abstraction for markets: it shapes what rate decisions look like across the region this week.

The Calendar That Makes This Urgent
Chile and Colombia rate decisions, Brazil jobs data and Mexico GDP are the key market events for the week of October 26 to 30, arriving directly after Brazil’s runoff.
Chile goes first. Chile’s central bank is almost certain to leave rates alone on Tuesday. The quiet decision hides a louder question: will the next move be up?
The rate sits at 4.5%. Traders expect no change, but a small minority of survey respondents now see a December hike. Chile’s copper-linked peso tends to move with risk sentiment across the region; a disorderly Brazil open could bleed into that read.
Colombia’s bank raised its rate by 0.25 points to 12.25% on September 30, so Friday’s meeting tests whether it pauses. With Lula’s win reinforcing the left-of-center bloc that also governs Colombia, investors will be watching whether the Banco de la República signals any fiscal accommodation or holds its hawkish posture.
Mexico’s third-quarter GDP estimate lands on Friday, with consensus sitting at 1.7%.

The Specific Risk for US Holders
After the first round, markets rose on the assumption of a Bolsonaro victory. A large part of today’s sell-off is a desire to unwind risk under positions previously taken for a Bolsonaro win, rather than a fresh assessment of Lula’s policies. That distinction matters for the opportunity.
Governability will be challenging, as Lula faces a more conservative Congress that may constrain his legislative agenda while also limiting fiscal expansion. Fiscal consolidation is likely to remain gradual, leaving debt concerns unresolved and supporting a higher-for-longer interest-rate outlook.
Investors are particularly concerned about the implications of a Lula administration for Brazilian interest rates, fiscal policy and the currency, factors that directly influence Nu’s net interest margins, credit quality and the dollar value of its real-denominated earnings. The same logic applies to ITUB and Banco do Brasil. On PBR, the risk is dividend policy: Lula’s prior term saw state-directed capital allocation at Petrobras that investors did not love.
The Bottom Line
Monday’s gap open in EWZ, PBR and NU is not the thesis. The thesis is whether a positioning unwind overshoots the fundamental reality. Bolsonaro is challenging the result over the extension of voting hours, but a legal reversal appears unlikely. Protests, judicial disputes and political tensions could persist.
That political noise extends the uncertainty premium on every Brazilian asset. With Chile pricing rates tomorrow and Colombia on Friday, any contagion in the broader Latin American complex would add a second layer of pressure to names already gapping lower. Watch the real at R$5.00. Lula’s re-election has shifted the market’s central assumption on fiscal policy, and every Brazilian asset is being priced through that lens. Until a finance minister and a credible budget signal emerge, the discount is unlikely to fully close.
