Today’s Focus
Colombia’s stocks and currency both lost ground on Thursday, one day before the central bank decides on interest rates. The COLCAP, the index of the Bogotá exchange’s most traded shares, fell 0.63% to 2,489.93 points.
The peso slipped about 0.5% to 3,167 per dollar, extending a run of weaker closes. Ecopetrol, the state-controlled oil company, fell 2.26% in New York.
The market now waits for Friday’s decision, with bettors split between a rise and a hold.
What matters today. The central bank’s Friday decision sets the cost of borrowing for Colombian households and companies, and a surprise would hit both the peso and bank shares.
01 The session in one read
The COLCAP closed at 2,489.93 points on Thursday 29 October, down 0.63% from 2,505.79 on Wednesday. The day’s range ran from 2,482.44 to 2,513.30.
In New York, Ecopetrol lost 2.26% to US$17.28, and Bancolombia, the largest bank, fell 1.17% to US$93.56. The iShares MSCI Colombia ETF, a US-listed fund, was not available in our feed.
The peso lost about 0.5%, ending at 3,166.65 per US dollar against 3,149.63 on Wednesday.
The COLCAP’s 0.63% loss was small but broad, and the weaker peso shows investors being careful ahead of Friday’s decision. Brent rose to roughly US$111, which normally supports Ecopetrol, so the share’s fall points to Colombia-specific caution.
We could not confirm a single trigger. The variable to watch is Friday’s rate decision at 18:00 UTC, according to the RT economic calendar.
02 The day’s numbers
| Measure | Level | Change | Read |
|---|---|---|---|
| COLCAP | 2,489.93 | −0.63% | Second lower close this week |
| USD/COP | 3,166.65 | +0.54% | Peso weaker |
| Brent oil | US$111 | +0.6% | Oil rose modestly |
| S&P 500 | 7,720 | −0.30% | Wall Street lower |
| US 10-year yield | 4.94% | −0.08 pt | Dollar rates eased |
The COLCAP’s intraday low of 2,482.44 was close to the final level, so sellers held control into the close. The index is about 0.7% below Tuesday’s 2,506.51.
The peso’s fall of about 0.5% matched weakness across Latin America, as Brazil’s real and Mexico’s peso also lost ground. Rio Times · Live Market Intelligence

03 Why it moved: oil shares and nerves before the bank
Ecopetrol’s New York shares fell 2.26% even as Brent stayed above US$110, a reminder that Colombian stocks are trading on local risk as much as on oil.
Bancolombia lost 1.17%, in line with banks across the region. We could not confirm a single trigger for the day’s fall.
The US economy grew 3.4% at an annual rate in the third quarter, the Bureau of Economic Analysis (BEA), the US statistics agency, said on Thursday, above the 3.2% forecast in the RT economic calendar. Firm US growth can keep the dollar strong against the peso.
04 The day’s movers
| Driver | Level / Move | Change | Note |
|---|---|---|---|
| Ecopetrol (EC) | State-controlled oil company | −2.3% | Weaker despite Brent near US$110 |
| Bancolombia (CIB) | Largest bank | −1.2% | Banks slipped |
| Brent oil | Global oil benchmark | +0.6% | About US$111 |
| USD/COP | Peso per dollar | +0.54% | 3,167 |
Ecopetrol and Bancolombia are the two Colombian companies most followed by US investors because their shares trade in New York.
We could not obtain reliable closing prices for other Bogotá-listed shares on Thursday, so only these two are shown.
05 The regional scoreboard
| Index | Country | Change |
|---|---|---|
| COLCAP | Colombia | −0.63% |
| Ibovespa | Brazil | −1.06% |
| IPC | Mexico | +0.87% |
| IPSA | Chile | −1.25% |
| Merval | Argentina | −1.0% |
Colombia fell less than Chile’s 1.25% and Brazil’s 1.06%. Argentina’s Merval lost about 1%.
Mexico’s IPC rose 0.87% and was the only major market in the region to gain.
06 The technical picture
The COLCAP has closed lower on two of the last three sessions and sits near the bottom of its recent range of about 2,480 to 2,515.
A close above 2,506 would suggest the market has absorbed the news; a fall below 2,482 would open a test of lower levels.
What Prediction Markets Say
On Polymarket, a prediction market, traders put the chance that Colombia’s central bank raises its rate by 0.25 percentage points at its October decision at 54.5%, and the chance it holds at 43.5%. They give 1.2% to a rise of 0.5 points or more. About US$70,000 has been traded on this market, as of 29 October 2026, 8:45 pm ET.
Prices on prediction markets are bets, not polls or forecasts by officials.
Why we show this: prediction markets turn real-money bets into a live probability that moves within minutes of the news, which is why investors, campaigns and newsrooms in the United States now follow them closely. We show them next to polls and official results, never instead of them.
07 What to watch
- Central bank decision: Banco de la República decides on Friday 30 October at 18:00 UTC; the previous rate was 12.25%.
- USD/COP above 3,170: A further peso fall would raise import costs and debt costs.
- Unemployment data: The September jobless rate is due on Friday, with a forecast of 9.2% against 9.4% before, according to the RT economic calendar.
- Oil prices: Brent near US$110 supports Ecopetrol and the state budget.
