Argentina holds Congressional elections on Sunday, 26 October in a race that has garnered more international media and financial market attention than would usually be the case for a partial midterm election. Half the seats in the Chamber of Deputies and one-third of the Senate are up for election, with the outcome set to have a significant impact on President Javier Milei’s ability to pass his policy programme through the legislature.
In this election preview, we will provide a short briefing on how the election works and who the main parties are, a chartpack of opinion polling and betting market data ahead of the vote, a scenario analysis examining the probabilities and implications of various outcomes, and an overview of the election with regard to financial markets.
