Background on Javier Milei and His Relevance

Javier Milei, a prominent right-wing politician in Argentina, secured a decisive victory in the recent legislative elections. His win is significant as he aims to strengthen his presence in the Congress, which has been dominated by the opposition. Milei’s ultraliberal economic plan is now poised for advancement, influencing Argentina’s financial landscape.

Market Performance and Key Players

The Buenos Aires Stock Exchange, represented by the Merval index, experienced a remarkable surge of 21.7% on Monday, marking its highest level since January 31st. This upswing was primarily driven by improved performances in liquid stocks with external valuations, particularly within the energy and financial sectors.

  • Leading the gains were Grupo Supervielle (47.99%), BBVA Argentina (40.75%), and Central Puerto, an energy generator (39.26%).
  • In the United States, Argentine American Depository Receipts (ADRs) also demonstrated strong performance during recent electoral cycles.

Trading activities in the U.S. focused on banks and companies linked to critical infrastructure and domestic consumption.

Impact on Argentine Economy

Milei’s victory suggests a full recovery of legislative initiative for the government, securing more than one-third of the Chamber of Deputies and nearly one-third of the Senate, with 13 senators added to their ranks.

In response to this political shift, Argentina and the United States have agreed on a currency swap worth $20 billion. Additionally, they are negotiating a rescue fund of another $20 billion with banks to support the ongoing policies championed by Milei.
