Brazilian financial markets suffered a violent repricing on Monday after Luiz Inácio Lula da Silva won the presidential runoff with 51.79% of valid votes, defeating Flávio Bolsonaro, who took 48.21% and refused to accept the result.
The commercial dollar opened at R$5.425, up 8.65% from Friday’s R$4.993, and reached R$5.605 by 9:47 a.m. Brasília time, a 12.25% surge. Ibovespa futures fell as much as 19.7%, and B3 triggered a circuit breaker at 10:03 a.m. after the cash market opened sharply lower. The iShares MSCI Brazil ETF (EWZ) dropped more than 27% in premarket trading, while Petrobras, Itaú Unibanco and Bradesco ADRs were down more than 20%.
Long-dated interest-rate futures also hit daily limits, with the January 2035 DI contract rising to 14.585% at 9:33 a.m. The National Treasury cancelled bond auctions scheduled for 27 and 29 October. B3 widened emergency daily limits on Ibovespa and dollar futures for Monday.
Analysts described the move as an unwinding of crowded bets. Prediction markets had priced Flávio Bolsonaro at about 80% before the weekend. JPMorgan cut the real and local government bonds from overweight to marketweight, while Gavekal Research said it would buy Brazilian assets after the sell-off. Leonardo Mendes of Manchester Investimentos said the market is repricing fiscal and institutional risk at the same time.
For crypto, the episode could accelerate Brazil’s existing tendency to shift into dollar stablecoins during periods of real weakness, although local exchange data was not yet available. The central bank is expected by traders to potentially intervene through dollar sales or swap auctions. Reference levels are R$5.20 on stabilization and R$6.00 if fiscal and institutional uncertainty persists.
