Brazil Markets Crater After Lula Victory, Some Stocks Plunge Up To 50%

Brazil's stock market plunged on Monday following Luiz Inácio Lula da Silva's presidential election victory, with the benchmark Ibovespa falling as much as 17.34% intraday and several major companies losing roughly half their market value.

The sell-off forced a temporary suspension of trading on the B3 exchange, while the U.S. dollar jumped approximately 12% against the Brazilian real at its intraday peak.

Domestic companies bore the brunt of the collapse. Shares in truck rental group Vamos, retailer Magazine Luiza and fashion chain C&A suffered intraday declines approaching or exceeding 50%.

Trading Halt As Ibovespa Plunges 17%

The Ibovespa entered Monday's session near its previous closing level of 205,083 points before falling sharply as investors reacted to the election result.

A 10% decline triggered a circuit breaker early in the session, suspending trading for 30 minutes. It was the first such interruption since the market turmoil of March 2020.

Selling accelerated after trading resumed. The index reached an intraday low of 169,516.43 points, representing a 17.34% decline from Friday's close.

The benchmark subsequently recovered some ground, trading between approximately 174,000 and 176,000 points during afternoon and late-session quotations. That still represented a loss of roughly 14% to 15%.

Trading volumes were elevated, while B3 expanded limits on futures contracts. A second circuit breaker was not activated despite the index breaching the normal 15% threshold, owing to technical conditions involving theoretical pre-opening prices.

The scale of the decline placed the market on course for one of its worst daily performances in decades, although the figures remained intraday rather than confirmed closing losses.

Individual Stocks Lose Up To 60%

The pressure was particularly severe among companies dependent on domestic consumption, financing conditions and interest rates.

Vamos shares fell approximately 51% to 60% at their intraday extremes, while Magazine Luiza declined around 48% to more than 50%.

C&A lost roughly 44% to 50%, and shares in exchange operator B3 dropped approximately 38% to 48%.

Financial companies also suffered heavy losses. State-controlled Banco do Brasil fell around 30% to 31%, while investment bank BTG Pactual declined approximately 30% to 37%.

Bradesco dropped between 23% and 27%, while Itaú lost more than 15%.

Petrobras preferred shares fell approximately 9% to 16%, reflecting concerns over the policy and fiscal implications of Lula's victory.

Other companies facing steep declines included Cyrela, Assaí, Localiza and Cosan.

Brazil's small-cap index also suffered a sharp sell-off, with reported intraday losses of approximately 30%. More than half the Ibovespa's components recorded double-digit declines.

Not all companies moved lower. Exporters benefiting from the weaker currency outperformed the broader market, with Vale gaining approximately 6% to 8% and pulp producer Suzano rising around 8% to 10%.

Gerdau and aircraft manufacturer Embraer were also among the relative outperformers.

Dollar Jumps 12% Against Brazilian Real

The equity collapse was accompanied by a sharp depreciation of the Brazilian currency.

The U.S. dollar climbed to approximately R$5.60–5.605 during Monday's session, an intraday increase of around 12% to 12.5% from Friday's level of roughly R$4.993.

The move represented one of the Brazilian real's steepest daily depreciations in more than two decades.

The currency subsequently recovered part of its losses, with the dollar trading around R$5.41–5.43 during afternoon quotations, still approximately 8% to 9% above its previous closing level.

Pressure extended into Brazil's debt markets.

Interest-rate futures surged across the yield curve, with some longer-dated contracts rising by more than 180 to 300 basis points. January 2031 contracts moved into the mid-14% to above-15% range, reaching trading limits at certain points.

Brazil's five-year credit default swap spread rose approximately 26%, from 120.2 basis points on Friday to 151.7 basis points, its highest level since mid-2025.

Longer-dated international bonds also declined, while the Brazilian Treasury canceled some scheduled bond auctions.

Lula Victory Reverses Market Expectations

The financial turmoil followed an election outcome that contradicted positioning across Brazilian assets.

Investors had increasingly anticipated a victory for Flávio Bolsonaro, associated in market expectations with tighter fiscal policies.

Those expectations had supported a strong rally following the election's first round. On October 5, the Ibovespa gained 7.7%, moving toward record levels of approximately 206,000 to 209,000 points.

Monday's losses abruptly reversed that positioning.

Lula secured 51.79% of the vote in Sunday's runoff, equivalent to approximately 64.26 million ballots. Bolsonaro received 48.21%, or approximately 59.83 million votes.

The difference amounted to roughly 4.43 million votes.

The result also marked the first occasion since Brazil's return to democracy that a candidate who finished second in the opening round went on to win the presidential runoff.

Bolsonaro Challenges Election Result

Bolsonaro has refused to concede defeat and said he would seek to annul the result.

His challenge centers on a last-minute Supreme Court decision extending voting hours, although both presidential campaigns had requested extensions.

Bolsonaro accused the court of altering the electoral process.

"I will not accept that the rules of the game were changed at the last minute... by Lula's friends in the Federal Supreme Court," he said.

Lula, meanwhile, called for national unity in his victory remarks.

"Once we win the elections, we no longer have adversaries. I have to govern for 215 million people," he said.

The president-elect also pledged an ambitious fourth term.

"I am going to deliver the best presidential term in the history of this country," Lula said.

For financial markets, the immediate consequence of the result was a sharp repricing of Brazilian equities, the currency and government debt.

The depth of Monday's intraday losses underscored the scale of the reversal after investors had positioned for a different election outcome.
