Argentina’s financial markets experienced a remarkable surge on Monday following the decisive victory of President Javier Milei, a key ally of former U.S. President Donald Trump, in the country’s midterm elections. This political success, coupled with a substantial $20 billion support package from the United States, has breathed new life into one of South America’s largest economies.
The Argentine benchmark Merval stock index soared by an astonishing 22%, while government bonds rebounded sharply, leading to lower yields. The Argentine peso showed significant resilience, climbing as much as 10% against the U.S. dollar before tapering its gains.
Milei’s party, La Libertad Avanza, achieved a stronger-than-expected result in the midterm elections held on Sunday, securing approximately 41% of the vote. This victory came as a relief for investors who had been troubled by weeks of political instability and market volatility, raising concerns about a potential financial crisis. Analysts suggest that Milei’s win provides him a renewed opportunity to implement critical economic reforms necessary for stabilization.
Economists from JPMorgan Chase remarked on Milei’s commanding mandate, stating, “After weeks of political turbulence, President Javier Milei has emerged as a decisive leader.” The victory not only halted a recent decline in the peso but also reinforced confidence among investors. The U.S. government had recently announced a $20 billion currency swap arrangement aimed at bolstering the peso and facilitating direct purchases of the Argentine currency.
U.S. Treasury Secretary Scott Bessent expressed optimism about Milei’s victory, highlighting a renewed mandate for economic reforms that could spur private investments and job creation in Argentina. “We look forward to continued steps toward economic freedom,” he stated, indicating the potential for improved prospects for the Argentine populace.
Milei’s administration, since taking office, has pursued aggressive fiscal reforms, adopting a “chainsaw approach” to government spending and promoting free-market policies as essential measures to counter high inflation. A win for the Peronist opposition could have severely jeopardized these efforts.
One of the key outcomes of the election was La Libertad Avanza’s successful acquisition of over one-third of the seats in the lower house of Congress, preventing the opposition from having enough votes to override presidential vetoes. However, political analysts caution that Milei will still require collaboration with centrist and center-right lawmakers to advance his legislative agenda.
Investor sentiment sharply improved post-election, with the Global X MSCI Argentina exchange-traded fund experiencing a remarkable 19% increase, marking its best day on record. This surge comes as Argentina’s markets were previously destabilizing, with a declining peso and rising bond yields reflecting a skepticism about Milei’s reform capabilities. The U.S. intervention to purchase pesos has provided a crucial lifeline for his administration.
Goldman Sachs’ LatAm economics head, Alberto Ramos, noted that the “strong and conclusive performance” of Milei’s party led to a reevaluation of Argentine assets, alleviating risks and enhancing the economic outlook. This fresh endowment of political capital, if effectively utilized to foster broader alliances, could bolster the governability and facilitate essential reforms, thereby supporting ongoing U.S. financial backing.
Despite these optimistic developments, economists advise caution, stressing that Argentina’s challenges are far from resolved. Concerns remain about the valuation of the peso, ongoing structural issues related to growth and employment, and the urgent need for comprehensive fiscal measures. Mauricio Monge, a senior economist at Oxford Economics, cautioned that the market rally does not signify the end of Argentina’s troubles but rather presents Milei with an opportunity to address pressing issues.
As Milei prepares for his reelection campaign in 2027, Trump’s previous remarks regarding U.S. support for the Argentine leader emphasize the relevance of political stability and reform effectiveness in determining future assistance.
