Argentina Markets: Merval & the Peso -- September 16, 2026

Argentina’s Merval index edged down Tuesday, but the session played out as a clear “two-speed” market. The S&P Merval slipped 0.16% to 3,079,779 points as banks pulled back, with Grupo Galicia down 1.7% and Banco Macro off 1.4%. Investors appeared to be taking profits in financials that have benefited from the “Milei reform trade,” while energy stayed in focus. YPF rose 2.4% after reports it is close to signing multiple liquefied natural gas (LNG) export contracts tied to Vaca Muerta. The peso was quoted at 1,506 per US dollar.
