Lula's Bruising Week Ends With Relief as Flávio Bolsonaro-Master Case Returns and PT Retrenches

How the Flávio Bolsonaro–Banco Master Files Changed the Week for Lula

President Luiz Inácio Lula da Silva's re-election campaign is closing one of its most difficult weeks of the year with a narrow opening: the unsealing of investigations around Banco Master has pushed Senator Flávio Bolsonaro's relationship with banker Daniel Vorcaro back into the headlines, creating new problems for the main opposition candidate. The development gave the governing camp a reprieve just as the race had tightened to a technical tie.

The latest public polls and internal trackers from both campaigns show the second-round contest between Lula and Flávio Bolsonaro effectively level. Some PT campaign numbers even placed the PL candidate slightly ahead by decimal margins, a shift that spread concern inside the government and optimism in the Bolsonaro camp. The erosion followed August reports about investigations involving Lula's son Fábio Luís Lula da Silva and a growing institutional crisis at the Supreme Federal Court, where Justice André Mendonça's attempt to remove Andrei Rodrigues as Federal Police chief pulled the clash into the Planalto.

After Justices Flávio Dino and André Mendonça collided over the police command, STF President Edson Fachin partially defused the confrontation by overturning two injunctions and confirming Rodrigues in the post. Fachin also scheduled a session for next week on the Master investigations and ordered the secrecy of the cases lifted. On Friday, that produced negative coverage for Flávio Bolsonaro, who is formally under investigation over his dealings with Vorcaro. The government supplemented the effort with measures to reduce taxes on gasoline, ethanol and diesel.

Officials acknowledge the expected impact on pump prices is small, but in a tight election any recovered voter matters, and fuel prices directly influence the president's approval rating. Inside the PT campaign, the week was spent trying to re-energize the base, recover lost votes and sharpen attacks on Flávio Bolsonaro. The campaign gained some room to maneuver, but party figures know the risks have increased, and some are pushing to revive a broad anti-Bolsonaro front after years in which Lula did little to cultivate voters who had backed him only as the lesser evil.

Why the Master Dossier, the STF Clash and Market Pricing Are Reshaping the Runoff

Why the Master Case Gives Lula a Real Reprieve

The unsealing of the Banco Master documents matters because it shifts the news cycle back to Flávio Bolsonaro's vulnerability, not his momentum. The senator is already under investigation over his relationship with banker Daniel Vorcaro, and the Dark Horse case earlier showed him allegedly demanding money from Vorcaro for a film about his father. For a race that campaign strategists expect to be decided by rejection rates, renewed coverage of that relationship gives Lula's team a usable line of attack at a moment when its own candidate was losing altitude.

The Supreme Court Has Become an Electoral Variable

The confrontation between Justices Flávio Dino and André Mendonça over control of the Federal Police was never only institutional. It landed in the middle of the campaign and forced STF President Edson Fachin to act. His decision to keep Andrei Rodrigues in office and to open the Master files next week means the court will likely remain a source of campaign-shaping headlines. That is unusual, but in this cycle the STF is not a neutral referee: its rulings on investigations, police leadership and sealed cases are directly affecting the candidates' political fortunes.

Markets Are Repricing More Than the Economy

Financial market commentary shifted as Lula's advantage narrowed. Analysts began saying the president's favoritism had diminished or disappeared, and that change helped lift asset prices such as equities and reduce interest-rate pressure. In other words, parts of the market were already treating a more competitive race as a possible change in policy direction. That link between legal and political news and asset prices means next week's STF session and any new Master disclosure could produce further volatility for Brazilian markets, not just for campaign strategists.

Lula's Structural Weakness Is the Lesser-Evil Voter

The final problem identified in the reporting is not tactical but structural. Lula has spent more than three and a half years in office without a sustained dialogue with the voters who supported him to avoid what they saw as a greater risk, while rejecting much of the PT agenda. A portion of that group has already said it will not vote for Lula again. That leaves the campaign with fewer fallback voters than in previous contests and increases its dependence on reducing Flávio Bolsonaro's acceptability rather than expanding Lula's own support.

What Campaigns, Investors and Voters Should Track Next

The story gives concrete signals for three audiences:

• Lula campaign and officials: The window from the Master disclosures is narrow and depends on next week's Supreme Court session producing more damaging material about Flávio Bolsonaro. Without new revelations, the underlying tie in the polls remains the campaign's baseline.
• Bolsonaro camp: The negative Banco Master headlines have punctured a favorable week; expect opponents to push the Vorcaro relationship as a rejection-raising issue rather than debate economic policy.
• Investors and market analysts: The improved odds of Flávio Bolsonaro have already been cited as a reason for stronger equities and lower interest-rate pressure. Next week's STF session and any Master-case leak or ruling are the next scheduled events capable of forcing a repricing.
• Voters and consumers: The fuel-tax measure should not be read as a major price change; the government itself expects only a small effect. Its real purpose is political, aimed at reversing a decline in presidential approval before the vote.
