Market Brief Week 41 — Brazil Just Surprised Everyone

Flávio Bolsonaro unexpectedly won the first round of Brazil's presidential election with 47.0% to Lula's 45.2%, and Brazilian assets had one of their best days in years. What the two almost opposite plans mean ahead of the 25 October runoff.

And the stock market loved it.

What happened on Sunday?

Brazilians voted in the first round of the presidential election. Polls had Lula ahead, but Flávio Bolsonaro, 45, son of ex-president Jair Bolsonaro, came first. Nobody reached 50%, so he faces Lula, 80, in a runoff on 25 October.

Jobs look great, but the economy is slowing down and Brazil pays a lot to borrow. Their answers to that are almost opposite.

How did markets react?

Investors see Flávio as the more budget-friendly choice. On Monday, Brazilian assets had one of their best days in years.

  • +12.6%: MSCI Brazil ETF (EWZ) in US dollars

Losers: exporters like Suzano and Embraer. A stronger real means they earn fewer reais.

What does this mean?

For Brazilians

Lula means more support for low incomes, but borrowing may stay expensive. Flávio promises lower interest rates and tougher policing, but with spending cuts in a weak economy.

For Brazil's market

A Flávio win helps banks and other rate-sensitive stocks the most. Exporters do better under Lula, because the real would likely weaken again.

For global markets

Flávio would move Brazil closer to the US, for example on critical minerals. China stays Brazil's biggest customer either way, and the EU–Mercosur deal has support on both sides.
