Brazil's Markets Just Had Their Best Day Since the Pandemic Betting on the Son of a Jailed Coup Plotter

Brazilian markets went euphoric on Monday after right-wing Senator Flávio Bolsonaro beat President Luiz Inácio Lula da Silva in Sunday's first round of the presidential election. The Ibovespa closed up 7.70% at a record 206,912 points, its first close above 200,000 and its biggest one-day gain since the pandemic.

The man investors are cheering is the 45-year-old eldest son of former President Jair Bolsonaro, who is serving a 27-year sentence for plotting a coup after losing the 2022 election.

A polling miss, then a stampede

Flávio, of the Liberal Party (PL), took 47.03% of valid votes to Lula's 45.16%, roughly 56.1 million against 53.9 million. Polls had forecast Lula leading by around three points. The two now meet in a runoff on 25 October.

Lula, who turns 81 later this month and is seeking a fourth term, told a crowd in Sao Paulo he had been convinced he would win outright in the first round. His campaign has tried to tie Flávio to his father's efforts to contest the 2022 loss and to brand him corrupt.

Markets shrugged that off. The dollar posted its steepest one-session drop against the real in eight years, falling about 4% to roughly R$5.00 from around R$5.22. Interest-rate futures plunged so hard that the B3 exchange raised its maximum daily fluctuation limit twice in a single session.

In New York, the iShares MSCI Brazil ETF jumped more than 12%. Itau Unibanco's ADRs gained 15% and Banco Bradesco surged 19%. Prediction markets moved just as fast: Kalshi went from about 60% to more than 80% for Bolsonaro, and Polymarket from 63% to 85%.

Pricing a promise

The bet rests on fiscal discipline. Investors see Flávio as more market-friendly and more serious about the budget, and Brazil's deficit-to-GDP ratio was almost 10% in June. Bond markets have shown elsewhere how harshly they punish fiscal drift, as the recent selloff in French debt made clear.

The right also did well in Congress. The PL elected 19 senators and will be the largest caucus in both chambers. One asset manager told Valor that Flávio "is practically elected, with a Senate that will provide the strongest base of support any president has ever had."

That confidence comes with a gap. Flávio and his advisers have yet to detail what they intend to do with the economy, and fiscal uncertainty remains ahead of the runoff. Traders are celebrating a program that has not been written down.

Three weeks early

Markets have effectively called the race three weeks before the vote. Prediction odds and analyst views lean toward Bolsonaro, but a first-round gap of about 2.2 million votes is not a landslide.

For now, Brazil's investors have made their choice: a record stock market and a stronger real, priced on the son of a man jailed for trying to overturn the last election, and on fiscal promises nobody has spelled out.
