Did Lula's victory cause a market collapse in Brazil?

Did Brazil's real, stock market and sovereign bonds collapse after Lula's re-election, as a post shared by Javier Milei claimed?

True, but…

Lula's victory triggered market turmoil, yet claims about voter alignment are unverified.

Yes, Lula's election win caused a sharp selloff in Brazilian assets. However, the characterization of left-leaning voters in the tweet lacks supporting evidence.

Claims

✓ 1 true

The average leftist doesn't mind voting for the same candidate as prisoners.4

“Al zurdo promedio no le hace ruido: votar al mismo candidato que los presos.”

– UnverifiableLow confidence

This assertion reflects a broad political generalization about left-leaning voters without supportive data. While leftist voters can vote, there is no comprehensive public data indicating that prisoners' votes had a decisive role in the election or that their voting patterns mirror those of the general leftist population. Thus, it is categorized as unverified rhetoric.

When that candidate wins, his currency, the stock market, and sovereign bonds collapse.123

“Cuando ese candidato gana, su moneda, la bolsa y los bonos soberanos se pulverizan.”

✓ TrueCentral claimHigh confidence

This part of the claim is substantiated by credible financial reports, which document a sharp decline in Brazilian assets following Lula's victory. After Lula's election on October 25, 2026, various sources confirmed significant market reactions: the Brazilian real weakened by approximately 10-12%, the Ibovespa fell sharply prompting circuit breakers, and there were considerable losses in sovereign bonds during this immediate aftermath. The independent market verification supports the accuracy of this part of the tweet's claim.

This tweet argues that typical left-leaning voters do not notice that voting for the same candidate as prisoners correlates with negative economic outcomes following that candidate's victory.

“👉Al zurdo promedio no le hace ruido: ❌Votar al mismo candidato que los presos😬 ❌Y que cuando ese candidato gana, su moneda, la bolsa y los bonos soberanos se pulverizan😬😬 😬 Para que les haga ruido deberian atar cabos Pero si los ataran, no serian zurdos😬 Poetico”

“👉The average leftist is not bothered: ❌Voting for the same candidate as prisoners😬❌And that when that candidate wins, their currency, the stock market and sovereign bonds collapse😬😬 😬 For them to be bothered, they would need to connect the dots. But if they did, they wouldn't be leftists😬 Poetic.” — translated

The full story

Luiz Inácio Lula da Silva's victory on October 25, 2026, in Brazil's presidential runoff led to an unexpected and severe reaction in the markets. The substantial market selloff included a 10-12% decline in the real against the dollar, major fall-offs for the B3 (São Paulo Stock Exchange) indexes, and high volatility in sovereign debt markets. Analysts noted that these reactions were likely due to misconceptions about the outcome being favorable to Lula, as market expectations had largely favored his right-wing opponent. Within a day, traders reacted dramatically, causing significant trading interruptions and prompting bond yields to spike, reflecting investors' fears about Lula's economic policies. Although the claim regarding the market reaction post-election is factually accurate, the tweet's implication that leftists vote similarly to prisoners is a rhetorical flourish lacking substantiating data, reflecting a broader narrative in political discourse rather than empirical evidence.

Kernel of truth

Lula's election caused real and immediate financial repercussions that were indeed felt across Brazilian financial markets.

How it was framed

Misleading content

The tweet conveys one accurate claim regarding market reactions but misrepresents information about voting behavior with a politically charged assertion.

  • Emotional language. The post uses emoticons and strong language to convey frustration about voter behavior.
  • Selective evidence. It emphasizes the market reaction but does not provide evidence for the voting claim.

Posted by Juan I. Fernandez (@juanif17) on Twitter, an account associated with politically charged commentary.

Bias

NoneSlightModerateStrong

Leans right-leaning / anti-left. The post uses derogatory language toward left-leaning people ('zurdo') and frames the argument to mock them; it is partisan commentary rather than neutral reporting.

Bias describes how the post frames its message — the slant of the language, selection and emphasis — and is judged separately from whether the claim is true. A true claim can still be framed with a strong slant.

Looks suspicious, isn’t proof

  • The claim relies heavily on political rhetoric rather than data.
  • It involves extreme language ('votar al mismo candidato que los presos'), possible exaggeration.
  • The partisan bias of the author may imply a lack of neutrality.

The actual evidence

  • Credible reports confirm that the Brazilian real and stock markets fell sharply after Lula's victory.

  1. 1

    Check trusted financial news sources.

    Look for reports on market reactions from reputable platforms like Reuters or Bloomberg after significant political events.

  2. 2

    Analyze claims for political bias.
