Mexico and Andean Stocks: IPC, IPSA, COLCAP, BVL — 2026-09-11
Mexico’s S&P/BMV IPC fell 1.09% to 64,106.82 on September 10 as a hot US Producer Price Index (PPI) report reinforced bets on a Federal Reserve rate hike, dragging the peso near 17.00 per dollar. Meanwhile, Colombia’s COLCAP surged 1.65% to record highs, decoupling from regional weakness, while Chile’s IPSA struggled with lithium sector headwinds and copper miners faced mixed signals from supply fears and tariff threats.

Top developments
Mexico IPC Drops on US Inflation Fears
On September 10, the S&P/BMV IPC closed down 1.09% at 64,106.82 units, reversing gains from earlier in the week. The decline was driven by a stronger-than-expected US Producer Price Index (PPI) report, which heightened expectations that the Federal Reserve may raise interest rates next week, strengthening the dollar and pressuring emerging market assets. The Mexican peso weakened to near 17.00 per dollar, impacting foreign investor sentiment toward local equities.

Colombia COLCAP Hits Record Highs
In stark contrast to Mexico and Chile, Colombia’s COLCAP index rose 1.65% on September 10, extending its rally from previous sessions where it hit a record 2,565.37 on September 8. The Colombian peso also firmed to near 3,119 per dollar, supported by August inflation data of 6.24% that aligned with market expectations for potential rate cuts by Banco de la República later in the year. This divergence highlights Colombia’s relative resilience amid broader Latin American volatility.

Chile IPSA Slides as Lithium Lags
Chile’s S&P IPSA index fell 1.16% on September 10, following a 1.14% drop on September 8, closing around the 11,300 level. The decline was led by weak performance in lithium and consumer discretionary stocks, while utility shares provided some support. The Chilean peso strengthened slightly to 925.28 per dollar on September 8, but the equity market struggled with global risk-off sentiment and specific sector underperformance.

Copper Miners Face Supply-Demand Tug-of-War
Copper-linked equities in Chile and Peru experienced volatility as US tariff threats collided with tight Andean supply and China’s energy-transition demand. On September 8, copper proxies jumped, but the sector faced pressure from falling Chilean production figures (down 9.4% in July due to storms) and mixed signals from China. Grupo México led losses in Mexico on September 10, reflecting the broader mining sector's sensitivity to global growth concerns and tariff uncertainties.

Local view
Local media in Mexico highlighted the "strong descent" of the BMV following the US PPI data, noting that the market is now pricing in higher-for-longer US rates which complicates Banxico's policy outlook. El Economista reported that the drop was broad-based, with significant selling in industrial and consumer stocks. In Chile, Diario Estrategia pointed to the IPSA's third consecutive weekly loss, citing global risk aversion and specific weakness in SQM and other lithium exporters as key drivers of the 1.16% Thursday decline.
