Shadow over 2026: the crisis in the STF that could redefine Brazil's presidential succession

A Financial Times report points to a clash between Alexandre de Moraes and André Mendonça as a factor of uncertainty capable of directly influencing the 2026 presidential race.

Shadow over 2026: the crisis in the STF that could redefine Brazil's presidential succession

Brazil's 2026 presidential race could be crossed by a factor that, in theory, should remain far from the ballot box: the climate of tension at the Supreme Federal Court (STF). That is the reading of the British newspaper Financial Times, which, in a report published on Sunday (13/9), classified the court's moment as a crisis with no parallel in recent memory — and warned that this scenario casts a shadow over the country's electoral process.

According to the publication, the central episode of this turbulence is the friction between justices Alexandre de Moraes and André Mendonça, described by the newspaper as a fierce dispute within Brazil's highest judicial body.

A clash that goes beyond the boundaries of the court

For the Financial Times, what is at stake is not limited to technical or administrative disagreements among judges. The report suggests that the STF's internal strain has gained enough political weight to interfere in how the electorate and the main party forces view the 2026 election.

The British newspaper treats the phenomenon as an element of instability that adds to an environment already marked by polarization and recurring questioning of institutions.

Why the presidential succession enters the equation

According to the published analysis, the crisis in the Supreme Court is not isolated noise: it would reverberate directly on the dispute for the Palácio do Planalto.

In this reading, any sign of a rift among justices is immediately given a political reading — and therefore an electoral one.

What the report highlights

The Financial Times focuses its narrative on the clash between Moraes and Mendonça, presented as the most visible point of a broader discomfort. The text describes the situation as a “fierce dispute” that “casts a shadow over the race” for the presidency.

The British newspaper's choice of words is not accidental: by speaking of a shadow, the publication indicates that the effect is neither direct nor immediate, but diffuse — capable of altering perceptions, feeding narratives and influencing the strategies of pre-candidates over the coming months.

The weight of the institutional variable

Historically, Brazil has already seen the Judiciary occupy the center of the news in election years. The difference pointed out now, according to the newspaper, is the combination of the court's relevance to the 2026 calendar and the intensity of internal friction.

This means that the STF's performance in the face of its own disagreements may become, in itself, a campaign issue.

An open scenario

The report does not project results or anticipate outcomes. What it does is record a symptom: Brazilian politics and its main court are, today, intertwined in a way that is difficult to separate.

The implicit conclusion is that the 2026 election will not be decided only at the ballot box, on the stump or on social networks — but also in how institutions, and the STF in particular, manage their fissures until then.
