## Recent evidence

- [confirms] Lula wins a fourth term in an upset, and investors who bet on Bolsonaro rush to unwind Brazil positions (2026-10-26): Lula's re-election keeps a left government in Brasília opposite Buenos Aires, and analysts in the Stellantis coverage expect trade with Brazil to stay restricted. That extends the ideological split the thesis says suppresses trade between Mercosur's two largest economies.
- [confirms] Stellantis halts Argentine car plants as sales and exports fall, and analysts expect trade with Lula's Brazil to stay restricted (2026-10-26): Stellantis is halting its El Palomar plant until the end of the month and pausing pickup production in Córdoba from December to mid-January as sales and exports fall. Analysts expect trade with Lula's Brazil to stay restricted, which is the recurring Argentine output cut the thesis predicts.
