Brazil election and Milei summit plan in Buenos Aires

Milei has made Brazil central to that plan. He is closely watching the election battle there, hoping conservative candidate Flávio Bolsonaro can challenge President Luiz Inácio Lula da Silva, after relations between Buenos Aires and Brasília soured enough for Brazil to downgrade its diplomatic representation in Argentina to chargé d’affaires level.

For investors, Brazil remains the main prize. The country has been the anchor of the Latin American equity rally, with the iShares MSCI Brazil ETF, EWZ, closing at $37.86 on Sept. 4 after a recent run that pushed it above both its 50-day and 200-day moving averages. The fund’s RSI reading of 82.7 points to stretched momentum, even as the broader trend stays firm.

The regional backdrop is also supportive of Milei’s pitch. Several governments in the proposed orbit — including in Chile, Paraguay, Ecuador and El Salvador — already share common ground on crime, narcotics and China policy, and some are linked to the U.S.-backed “Shield of the Americas” framework. That gives the project a geopolitical edge beyond symbolism, especially if it becomes a platform for aligning security and investment policy.

Argentina’s own market exposure remains more mixed. The iShares Latin America 40 ETF, ILF, ended at $36.07 on Sept. 4, below its 50-day average but above its 200-day line, while the iShares MSCI Argentina ETF, ARGT, closed at $96.41, holding near recent highs. That suggests traders are still willing to price in political optionality, even as Milei’s domestic standing has come under pressure.

The question now is whether the summit can move from rhetoric to logistics. The date has not been set, and security and protocol issues are slowing the process, but the broader regional trade is clear: Latin America’s rightward shift is becoming more organized, and Brazil’s vote could determine how durable it becomes.
