Brazilian markets plunged and erased more than $200 billion in value at Monday’s open after Luiz Inácio Lula da Silva stunned markets by defeating Senator Flávio Bolsonaro in Sunday’s runoff — a result that many prediction markets had put at only about a 20% chance.
Key market moves
- The iShares MSCI Brazil ETF (EWZ) — a New York-traded basket of Brazil’s largest equities — plunged as much as 26% from Friday’s close of about $42.60, hitting $31.40 before trimming losses to roughly 23% at $32.84 by 10:38 a.m. ET. That level effectively wipes out EWZ’s strong 34% gain earlier in 2026, leaving the fund roughly flat year-to-date.
- Brazil’s benchmark Ibovespa tumbled as much as 17% to about 170,000 points. B3, the São Paulo exchange, triggered its first circuit breaker since the COVID-19 pandemic, halting trading for 30 minutes after a 10% drop — but selling resumed once markets reopened.
- The U.S. dollar surged against the Brazilian real, rising by as much as 12% at one point. For a dollar-based investor, the combined equity and currency moves produced losses near 26% in the worst moments, consistent with EWZ’s fall.
What drove the shock
Markets had been pricing a Bolsonaro victory after he unexpectedly led the Oct. 4 first round with 47.03% of valid votes to Lula’s 45.16%. That result prompted a rally: Ibovespa jumped 7.85% the next day and EWZ gained more than 10% on expectations Bolsonaro would pursue fiscal tightening and lower interest rates. Monday’s outcome reversed those bets and, at its lows, left the Ibovespa about 11% below its Oct. 2 level.
Prediction markets and polls
- Prediction platforms gave Bolsonaro high odds: Polymarket showed an 82% chance the day before the runoff, and Kalshi had him near 80% on Sunday morning.
- Conventional polling, however, suggested a much closer race: Datafolha showed a tied race at 50% each (valid votes), and CNT/MDA’s mid-October poll had Bolsonaro slightly ahead 50.5% to 49.5%.
- Official results from Brazil’s Superior Electoral Court put Lula at 51.79% versus Bolsonaro’s 48.21% — a margin of about 4.4 million votes.
Political fallout
Bolsonaro said Sunday night he would not recognize the result and planned to ask the courts to annul the election, reversing an August pledge to respect the outcome. He objected to a Supreme Court decision by Justice Cristiano Zanin to extend voting until 7 p.m. at Lula’s campaign request, calling it a midgame rule change; Bolsonaro’s team had also sought extra voting time in parts of three states. “It is impossible to recognize the result of the elections in the context in which these things happened,” he said outside his campaign headquarters in Brasília.
What this means for crypto-focused readers
Sharp swings in equities and FX in major emerging markets can spill into risk assets globally. The same volatility that shook EWZ to "memecoin-sized" moves may push some Brazilian investors toward dollar- or crypto-denominated options as hedges, while overall risk-off sentiment could weigh on crypto prices in the short term. Watch FX pressure on the real, local on-chain flows, and any regulatory signals from the incoming government — all potential drivers for crypto markets in Brazil.
