Brazil's Ibovespa Soars 7.7% to Record on Bolsonaro's Election Lead

Brazil's main stock index jumped 7.7% to a record 206,912 on Monday, Oct. 5, after Flávio Bolsonaro edged out President Lula in the first round of voting.

Why it matters

  • The Ibovespa had its biggest one-day gain in more than six years, Trading Economics said, and closed at a record.
  • Investors see Flávio Bolsonaro as more fiscally conservative than President Lula, so his first-round lead lifted stocks and the real.
  • The two candidates meet in a runoff on Oct. 25, so the election is not settled and prices could swing again.

Brazil's benchmark Ibovespa stock index surged 7.7% to a record 206,912 on Monday, Oct. 5, after senator Flávio Bolsonaro finished ahead of President Luiz Inácio Lula da Silva in Sunday's first round of the presidential election, Trading Economics reported. It was the index's biggest one-day gain in more than six years.

The Brazilian real also strengthened sharply, moving below 5 reais per U.S. dollar.

What happened in Brazil's election?

Flávio Bolsonaro, the son of former president Jair Bolsonaro, won 47.03% of the vote on Sunday, Oct. 4. Lula received 45.16%, Euronews reported. Neither candidate reached the 50% needed to win outright, so the two will face each other in a runoff on Oct. 25.

The result was a surprise. Polls had shown Lula ahead, according to Latin Times.

Why did Brazilian stocks jump?

Investors see Bolsonaro as more fiscally restrictive than Lula, Trading Economics said. Euronews reported that his platform includes scrapping taxes, measures to rein in public debt and the privatization of dozens of state-owned companies.

The Ibovespa crossed 200,000 points for the first time in its history on Monday, Latin Times reported. It closed up 14,797 points, according to Trading Economics. The session set a record for trading activity, with more than 5 million trades.

Banks and the exchange operator led

Financial stocks posted the biggest gains, Trading Economics reported.

In New York, U.S.-listed shares of the digital bank Nu Holdings rose 13.03%, and Petrobras's U.S. shares gained more than 13%, Yahoo Finance reported.

What happened to the Brazilian real?

The real traded at 4.98 per dollar on Monday, compared with 5.22 at Friday's close, Euronews reported. Trading Economics said the currency strengthened to below 5.00 per dollar, a 17-month high.

What comes next

BTG Pactual, Latin America's largest investment bank, estimates that a Bolsonaro victory on Oct. 25 could push shares of B3 up by as much as 45%, Euronews reported. Trading Economics noted that the narrow margin means volatility is likely to continue through the campaign.
