Colombian Market Close, Oct. 28, 2026: COLCAP Breaks Below 2,500 as ISA Slides and Ecopetrol Rallies on Oil

For U.S.-based investors with Colombian exposure, through the Ecopetrol (EC) and Bancolombia/Cibest (CIB) ADRs, Latin America ETFs, or direct accounts, Wednesday was a reminder that local stocks and the peso move together. The MSCI COLCAP fell 0.73% to 2,488.21, losing its 2,500 support as banks and utilities sold off, while Ecopetrol rallied 2.8% on $100-plus oil. The peso slipped about 0.2% after the Fed’s hawkish hold, trimming dollar returns.

The peso and the Fed

The Fed held at 3.75%–4% but two officials wanted a hike. For Colombia, a December hike would narrow the rate gap that has powered carry-trade inflows and the peso’s roughly 20% rally this year. USD/COP rose 0.22% to 3,157.49. See why the peso is so strong.

Today’s headlines

  • Fed: 10–2 hold under Chair Kevin Warsh; a December hike remains possible.
  • Oil: WTI +2.6% to $102.48, Brent +2.0% to $111.64, supporting Ecopetrol.
  • Gold: above $4,000, lifting Mineros.
  • TRM: Wednesday’s official rate was 3,148.02.
  • Earnings season: Nutresa reports Friday, Oct. 30; ISA on Nov. 5.

The dollar-investor view

ExposureWednesday’s effect in USD terms
Ecopetrol (local or EC ADR)Oil-driven gain, slightly reduced by a weaker peso
Bancolombia / Cibest (CIB ADR)Bank weakness plus a softer peso
iCOLCAP / broad Colombia exposureAbout −0.7% in pesos, roughly −1% in dollars
Peso cash or TES bondsSmall currency loss after the Fed

The bigger picture for foreign investors: the peso has strengthened about 20% this year on carry-trade inflows. A Fed that leans toward hiking narrows Colombia’s rate advantage, which is the main risk to dollar returns from here.

Critical take

Breaking 2,500 while Ecopetrol rallies is a weak technical signal: the index’s main engine rose, but the rest of the market did not follow. Losses concentrated in banks and utilities, the sectors most sensitive to interest rates. With TES yields above 13% and a Fed that has not ruled out hiking, the cost of capital remains the key brake on Colombian equities, even after a year in which iCOLCAP is up more than 20%.

What to watch Thursday, Oct. 29

  • Whether COLCAP reclaims 2,500.
  • Peso reaction to Big Tech earnings and Fed repricing.
  • Ecopetrol versus crude; Nutresa results on Friday.
