Today’s Focus
Colombia’s COLCAP index closed Tuesday’s session at 2,588.64, a gain of 0.90%. The benchmark tracks the most liquid shares on the Bogotá exchange.
The advance did not come from oil. Gains in industry, services and agriculture drove the index, while energy shares slipped.
Ecopetrol, the state-controlled oil producer and the exchange’s best-known name, fell 3.21% to 2,715 pesos (about US$0.85). The telecoms group ETB led the market with a rise of 5.83%.
The peso gave up a little ground. The dollar ended the local session at 3,203, up 0.13% from Monday’s close of 3,199.
What matters today. Equities rose without help from crude, which is unusual for a market this tied to Ecopetrol.
01 The session in one read
Colombia’s stock market closed higher on Tuesday. The COLCAP index gained 0.90% to 2,588.64, up from 2,565.55 on Monday 21 September 2026.
It was the benchmark’s fourth consecutive daily gain. The index had already risen 0.68% on Monday and 1.05% on Friday 18 September 2026.
Energy was a drag rather than a driver. Ecopetrol and the fuel retailer Terpel were among the three biggest fallers of the day.
Conversions in this article use a rate of 3,208.66 to the US dollar. That is the official market rate certified by Colombia’s financial regulator for Wednesday 23 September 2026.
The session breaks the usual pattern. Colombian equities normally follow crude, because Ecopetrol is the market’s heaviest name.
On Tuesday they did not. Buyers moved into telecoms, gas distribution and infrastructure while the oil names fell.
The variable to watch is the dollar. The official rate for Wednesday already sits above Tuesday’s market close, which points to a firmer greenback.
02 The day’s numbers
| Measure | Level | Change | Read |

| Dollar, session range | 3,193.80–3,218 | — | Low and high on the day |
| S&P 500 | 7,764.64 | — | US equities all but unchanged |
| US 10-year yield | 4.968% | +0.005 pt | Global rates barely moved |
Trade date: Tuesday 22 September 2026. All figures are closing levels.
Colombia’s official rate is known as the TRM. The regulator calculates it from each session’s trades and applies it the following day.
That is why the two dollar figures differ. The market closed at 3,203 on Tuesday, while the rate certified for Wednesday came out at 3,208.66. Rio Times · Live Market Intelligence

03 Why it moved — crude down, equities up
Oil fell on Tuesday. Brent crude slipped about 1% to around US$99 a barrel, with the US benchmark near US$95.
Traders linked the drop to reports that Iran had offered to reopen the Strait of Hormuz. That would ease one of the year’s biggest supply worries.
Cheaper crude explains Ecopetrol’s 3.21% fall. It does not explain the index, which rose on buying in telecoms, gas and infrastructure names.
The peso’s small slip came with the dollar firm across markets. Traders were waiting on Federal Reserve commentary about the pace of rate cuts.
The trading firm JP Tactical Trading said the dollar met resistance near the top of its expected range and pulled back. The session high was 3,218 and the low 3,193.80.
04 The day’s movers
| Stock | Close | In US$ | Change | Note |
|---|---|---|---|---|
| ETB | 127.00 | US$0.04 | +5.83% | Bogotá telecoms group; day’s best |
| Promigas | 6,060.00 | US$1.89 | +4.84% | Gas distributor; Monday’s worst |
| Grupo Argos, preferred | 16,920.00 | US$5.27 | +4.44% | Cement and infrastructure holding |
| Terpel | 18,860.00 | US$5.88 | −3.28% | Fuel retailer; day’s worst |
| Ecopetrol | 2,715.00 | US$0.85 | −3.21% | State-controlled oil producer |
| Corficolombiana | 22,520.00 | US$7.02 | −2.85% | Financial holding company |
Closing prices are in Colombian pesos, with the US dollar value beside each one. The six names above were the session’s three largest gainers and three largest fallers.
Promigas is worth a second look. It had been Monday’s weakest stock, falling 3.67% to 5,780, before Tuesday’s rebound.
The pattern is a rotation out of energy. Money moved towards telecoms, gas distribution and holding companies instead.
05 The regional scoreboard
| Index | Country | Change |
|---|---|---|
| IPC | Mexico | +1.45% |
| Ibovespa | Brazil | +0.44% |
| Merval | Argentina | −0.04% |
Mexico’s IPC led the region, closing at 64,456.59. Brazil’s Ibovespa added 0.44% to 187,422.92.
Argentina’s Merval was the outlier, slipping 0.04%. The live market board above carries the latest closes for the other regional bourses.
06 The technical picture
The COLCAP has now gained in four straight sessions. It has climbed 2.6% since its close of 2,521.85 on Thursday 17 September 2026.
The 2,550 area capped the index last week. The benchmark is now well clear of it.
For the dollar, Tuesday’s close of 3,203 sits between the session’s extremes. Support is near the low of 3,193.80 and resistance near the high of 3,218.
07 What to watch
- Federal Reserve signals: Rate-cut commentary moves the dollar, and the peso tends to follow
- Crude prices: Brent’s direction remains the clearest single driver for Ecopetrol
- Energy rotation: Whether buyers return to Ecopetrol and Terpel after Tuesday’s falls
- The official rate: Wednesday’s certified rate of 3,208.66 already sits above Tuesday’s market close
Background: Colombia’s COLCAP Jumps 1.03% as the Peso Slides to 3,166.69 per Dollar.

Frequently Asked Questions
What is the COLCAP?
It is Colombia’s main stock index, tracking the most liquid shares on the Bogotá exchange, much as the Dow does in the United States.
Why did the peso weaken?
The dollar was firm everywhere before Federal Reserve remarks on rate cuts, and it closed at 3,203 in Colombia, up 0.13% on the day.
Did oil lift the market?
No. Brent crude fell about 1% and Ecopetrol dropped 3.21%, so the index rose on industry, services and agriculture shares instead.
What is the TRM?
It is Colombia’s official exchange rate. The regulator works it out from one session’s trades and applies it the next day, which is why it lags the market.
