Background on Javier Milei and His Political Significance

Javier Milei, an Argentine politician and leader of the libertarian La Libertad Avanza party, suffered a significant defeat in the recent legislative elections for Buenos Aires province. This loss has sent ripples through Argentina’s financial markets, causing a “black Monday” for investors.

Argentina’s Market Performance

The impact of Milei’s defeat was evident across various sectors in Argentina:

  • Bonds in dollars: Fell by approximately 0.5 per dollar, marking one of the largest declines since April.
  • S&P Merval Index: Plummeted 13.3% in Argentine pesos and 22.3% in US dollars.
  • Key stocks: Supervielle (-21.2%), Grupo Financiero Galicia (-20.1%), BBVA Argentina (-20.3%), Banco Macro (-19.1%), YPF (-11%), Vista (-5.9%), and Mercado Libre (-1.7%) experienced substantial drops.

The Argentine peso also weakened, falling over 3% against the US dollar.

Contagion Effect on Chilean Stocks

The turmoil in Argentina’s markets had a spillover effect on Chilean equities. The IPSA, Chile’s benchmark stock index, declined 1.3% to 9,089.29 points, ending its streak of five consecutive record highs.

Several Chilean companies with operations in Argentina were among the worst performers:

  • Cencosud: Fell 3.9%, and is heavily weighted in the benchmark index.
  • Falabella: Dropped 3.4%.
  • Andina-B: Declined 3.1%.
  • Latam: Experienced a 3% decline.
  • CCU: Declined 2.7%.
  • Concha y Toro: Fell 1%.

José Agustín Cristi, portfolio manager of Zurich AGF’s Chilean equities, explained the situation: “Investors are less optimistic about their companies due to exposure in Argentina. Chilean firms with Argentine operations were among the hardest hit, alongside retail companies that have relied on Argentine consumers in recent times.”

Market Concerns and Future Implications

The market’s reaction reflects concerns that Milei may struggle to maintain support for his austerity agenda, potentially jeopardizing plans to re-engage with global financial markets.
