Mexico and Andean Stocks: IPC, IPSA, COLCAP, BVL — 2026-10-25
Mexico’s IPC closed slightly lower on October 23 as the peso gained ground, marking a volatile week where nearshoring hopes clashed with tariff tensions. Meanwhile, Chile’s IPSA slid 1.88% on Thursday due to copper price declines, though a key mine approval and lithium price stabilization offered some counter-narratives. Regional markets faced pressure from a broader LatAm tech sell-off and rising oil prices, with investors eyeing imminent central bank decisions and election outcomes in Brazil.

Chile’s IPSA Drops as Copper Slides
Chile’s IPSA index fell 1.88% on Thursday, October 22, closing at 10,780, driven by a decline in copper prices and a weakening peso at 986.2 per dollar. The pressure continued into Friday, October 23, with the IPSA falling another 0.31% and the peso weakening to 994.76, its weakest close since early October. Copper itself fell 1.23% to US$6.54 a pound for the week ending October 23, partly due to the end of a strike at the Centinela mine, which removed some supply-risk premium.

Tariff Tensions and Nearshoring Signals
President Trump stated on October 23 that a tariff deal with Mexico was "very close," a sentiment echoed by Mexican President Sheinbaum, though 50% steel and 25% car tariffs remain in effect. This political uncertainty weighed on Mexican equities, even as nearshoring winners like Grupo Mexico announced they would press ahead with major US copper projects despite output dips.

Copper Mine Approval Boosts Chilean Sector
In a positive development for the Andean mining sector, Chile’s Antofagasta commission unanimously approved the US$870 million Tovaku copper mine, a joint venture between Pucobre and Codelco, on October 23. This approval, granted after a 450-day review, signals regulatory stability for mining investments in the region, potentially offsetting some of the negative sentiment from falling copper prices.
