Market Performance Overview

- Argentina: S&P Merval finished at 3,024,971.01, up 0.53%. Wholesale peso rose to 1,514 per US$ (+0.2%).

Drivers and Context
- U.S. inflation impact: A PCE price index of 3.7% YoY boosted the dollar, pressuring the Chilean peso and Mexico’s IPC.
- Chile’s sectoral weakness: Bank and retail stocks led the decline; Mallplaza -2.8%, Latam -2.5%, Copec -1.6%, Banco de Chile -1.5%.
- Argentina’s reform momentum: The lower house approved a Central Bank charter overhaul (144-102), aiming to end temporary advances to the Treasury and tighten monetary discipline. Heavy dollar demand and a Treasury auction of 12.6 trillion pesos (?US$8.3 bn) lifted the peso.
- Mexico’s monetary stance: Banxico Governor Victoria Rodríguez Ceja said future rate moves have “no preset path,” keeping the policy rate at 6.50% and raising the 2026 growth forecast to 1.5%.
