Brazil Markets Rally After Flavio Bolsonaro Leads First Round

Brazilian financial markets rallied sharply on Monday after Senator Flavio Bolsonaro (PL) won 47.03% of valid votes in Sunday's presidential first round, ahead of incumbent Luiz Inacio Lula da Silva (PT) at 45.16%. The runoff is scheduled for October 25.

The Ibovespa index jumped over 8% to surpass 209,000 points for the first time, while the real appreciated more than 3% to below 5.00 per dollar. Long-term DI futures rates plunged over 130 basis points, with the January 2035 contract falling to 12.80% from 14.13%.

“There is an important difference between expectation and delivery.”

Treasury Direct fixed-rate bonds posted their second-largest single-day rate drop since 2008. The Prefixado 2032 yield fell 120 basis points to 12.95%, and the IPCA+ 2050 dropped 74 basis points to IPCA + 6.32%.

Analysts attributed the move to expectations of stricter fiscal policy and potential interest-rate cuts under a Bolsonaro administration. Capital Economics estimated Brazilian assets could rise 3-4% based on 2018 and 2022 election reactions.

Argentine assets rallied in sympathy. The S&P Merval rose 3.5-3.7%, led by banks and energy shares, while country risk fell 49 basis points to 599, breaking below the 600 threshold. Mercado Libre ADRs surged nearly 10% on its Brazilian exposure.

A stronger real benefits Argentine exporters, as Brazil receives nearly 30% of Argentina's total exports. Bilateral trade reached US$19 billion in January-August 2026.

Markets now await concrete fiscal proposals before the runoff, with some analysts cautioning that the initial euphoria may not consolidate without policy delivery.
