Key Takeaways
- Argentine markets surged after Milei’s party won midterm elections
- Merval stock index jumped 22%, peso gained 10% against dollar
- US provided $20 billion support package for Argentina’s economy
- Victory gives Milei stronger mandate for economic reforms
Argentina’s financial markets experienced a massive rally on Monday following President Javier Milei’s decisive midterm election victory and a $20 billion lifeline from the United States. The political win has boosted investor confidence in Milei’s ability to push through economic overhauls and stabilize South America’s second-largest economy.
The benchmark Merval stock index soared 22% while government bonds rallied sharply. The Argentine peso surged as much as 10% against the US dollar before paring some gains. The Global X MSCI Argentina ETF jumped 19%, posting its best day on record.
Political Mandate Strengthened
Milei’s La Libertad Avanza party secured approximately 41% of votes in Sunday’s legislative elections, substantially outperforming the Peronist opposition. The party gained over one-third of seats in the lower house, preventing the opposition from overriding presidential vetoes.
“After weeks of political turbulence and pronounced market volatility, President Javier Milei has emerged with a commanding mandate from the Argentine electorate,” economists at JPMorgan Chase said in a note.
The victory halted a recent slide in the Argentine peso that had occurred amid growing investor skepticism about Milei’s reform prospects.
US Support and Market Impact
The US government earlier this month announced a $20 billion currency swap to support the peso, along with direct purchases of the currency. US Treasury Secretary Scott Bessent welcomed the election outcome.
“President Milei has a renewed mandate for change,” Bessent stated on social media. “We look forward to continued steps toward economic freedom that will attract private sector investment and job creators, bringing prosperity to the Argentine people.”
Former President Donald Trump, who had made US support contingent on Milei’s political success, celebrated the victory: “Our confidence in him was justified by the People of Argentina.”
Reform Challenges Ahead
Despite the market euphoria, economists caution that significant challenges remain. Argentina continues to face structural issues with growth, employment, and fiscal policy.
“The rally is not a sign that Argentina’s problems are over,” said Mauricio Monge of Oxford Economics. “The Argentine peso is still overvalued… But now Milei has the chance to carry out these measures.”
Since taking office in late 2023, Milei has implemented aggressive spending cuts and free-market policies to combat runaway inflation. The midterm victory provides crucial political capital to continue these reforms, though he will still need support from centrist and center-right lawmakers to pass legislation.
