Mexico and Andean Stocks: IPC, IPSA, COLCAP, BVL — 2026-09-11
Latin American markets faced a volatile week ending September 11, with Mexico's IPC entering a third consecutive weekly decline amid Fed rate fears and Banxico speculation. While Colombia's COLCAP hit record highs driven by Ecopetrol and peso strength, Chile's IPSA slid due to lithium weakness and supply concerns, despite a copper surge earlier in the week.

Top developments
Mexico’s IPC Posts Third Weekly Loss Amid Rate Anxiety
The S&P/BMV IPC closed lower on Thursday, September 10, falling 1.09% as investors reacted to rising US yields and fears of a Federal Reserve rate increase. This marked the third consecutive weekly decline for the Mexican index, which has now lost 1.21% year-to-date in recent trading sessions. Market sentiment was further dampened by reports suggesting Banco de México (Banxico) might raise rates by 25 basis points next week to combat inflationary pressures.
Colombia’s COLCAP Hits Record Highs on Peso Strength
Colombia’s benchmark index, the COLCAP, continued its upward trajectory, closing at a record 2,584.02 on Friday, September 11, up 0.57%. The rally was supported by a firmer Colombian peso near 3,099 per dollar and strong performance from energy stocks like Ecopetrol. Earlier in the week, the index had already surged 1.65%, reflecting investor confidence in local policy stability and commodity exports.
Chile’s IPSA Falls as Lithium Slump Offsets Copper Gains
Chile’s S&P IPSA index dropped 1.16% on Thursday, September 10, following a 0.39% decline on Wednesday. The slide was largely driven by weak performance in lithium stocks, with Albemarle and SQM falling 3–4% on Friday due to ample supply and softening Chinese carbonate prices. This negative sentiment overshadowed earlier copper gains, where Andean supply fears met China's energy-transition demand, pushing copper proxies higher earlier in the week.

Peru’s BVL Attracts Foreign Capital via Mining ADRs
The Lima Stock Exchange (BVL) saw increased foreign interest, particularly in mining-heavy sectors, as investors sought exposure to stable sol currency and mining assets. Recent reports highlight that Peru is maintaining favorable mining laws under President Fujimori, making it an attractive destination for foreign capital despite regional volatility. Copper-linked miners remained key performers, benefiting from the structural demand narrative even as broader Andean indices fluctuated.
Local view
Local media outlets in Mexico are highlighting the pressure on the peso and the business community's call for Banxico to lower rates rather than raise them. Investing.com reports that entrepreneurs are petitioning Banxico to cut rates to mitigate the impact of a "Superpeso" on exporters, creating tension with market expectations of a hike. In Chile, Diario Estrategia noted the specific daily close variations, emphasizing the consecutive daily drops in the IPSA, while El CEO focused on the correlation between BMV and Wall Street declines driven by Fed probability shifts.
