Colombia Markets: COLCAP & the Peso — August 4, 2026
Key Facts
- The COLCAP closed at 2,384.67 points, shedding 0.31 per cent as six of the nine tracked names finished lower
- The Colombian peso weakened to 3,158 per US dollar, a decline of 0.37 per cent that left it hovering just above its 52-week low
- Nine names changed hands, three higher and six lower, with Tecnoglass the standout at plus 7.64 per cent and Ecopetrol off 1.01 per cent
- The regional picture was mixed, with Brazil’s Ibovespa flat and Chile’s IPSA gaining 0.30 per cent while Mexico’s IPC shed 0.35 per cent
- The US S&P 500 rallied 1.48 per cent, but a 4.73 per cent slump in Brent crude kept a lid on the energy-heavy Bogotá board
Today’s Focus
The COLCAP, Colombia’s benchmark equity index, slipped 0.31 per cent on Monday to 2,384.67 points, with decliners outnumbering advancers six to three across the nine names that traded. The Colombian peso also weakened, losing 0.37 per cent to settle at 3,158 pesos per US dollar, leaving USD/COP just above the 3,122 mark at the bottom of its annual range.
Beneath the index, the board was ordinary rather than empty. Ecopetrol slipped 1.01 per cent to US$16.60 on turnover of 2.37 million shares, and Bancolombia fell 1.57 per cent to US$91.07, while Tecnoglass ran 7.64 per cent higher to lead the advancers. What was missing was a domestic catalyst—no major corporate news and no local data to shift the wider tape.
Globally, US equities climbed with the S&P 500 adding 1.48 per cent, but the positive tone did not spill over into Colombian assets. Oil, the country’s key macro anchor, went the other way: Brent fell 4.73 per cent and WTI 5.11 per cent, a slump that landed directly on Ecopetrol and capped the energy-heavy COLCAP.
What matters today. A market drifting lower with crude, waiting on the central bank’s minutes for its next domestic cue.
01 The session in one read
Colombia’s stock market fell gently on Monday. The COLCAP, the yardstick for the country’s largest and most liquid shares, shed 0.31 per cent to close at 2,384.67 points, with six of the nine names on the board lower and three higher—a drift rather than a sell-off.
The peso also drifted lower, with the dollar buying 3,158 Colombian pesos at the close, a rise of 0.37 per cent for USD/COP. In plain terms, the local currency weakened a touch, continuing to trade near the 3,122 level that marks its 52-week low—the strongest point for the peso in the past year.
The heavyweights did the work. Ecopetrol, the state-controlled oil producer that sets the tone for the whole index, closed at US$16.60, down 1.01 per cent on turnover of 2,372,149 shares—comfortably the most active name of the day. Bancolombia, the country’s largest bank, fell 1.57 per cent to US$91.07 with 304,196 shares traded, and Grupo Aval eased 0.76 per cent to US$5.24.
A rise in global stocks, which saw the S&P 500 add 1.48 per cent, was offset by a heavy day for crude, with Brent down 4.73 per cent and WTI 5.11 per cent. With oil pulling one way and Wall Street the other, Colombian equities drifted, and traders switched their attention to the week’s coming events—including minutes from the Banco de la República’s last monetary-policy meeting.
The evidence points to a market taking its cue from commodities rather than from anything domestic. Decliners beat advancers six to three, and the index’s two heaviest weights—Ecopetrol and Bancolombia—both closed lower, which is enough on its own to explain a 0.31 per cent dip in the COLCAP. The weight of the evidence sits on crude: a 4.73 per cent slide in Brent lands straight on Ecopetrol and, through the export account, on the peso. Tecnoglass’s 7.64 per cent jump was the clear outlier, a stock-specific move rather than a signal about Colombian risk. The one variable to watch is whether oil steadies before the central-bank minutes land.
02 The day’s numbers
| Measure | Level | Change | Read |
|---|---|---|---|
| COLCAP | 2,385 | −0.31% | Six of nine names lower; index drifted |
| Session range | — | — | Intraday high and low not disclosed for the session |
| USD/COP | 3,134 | +0.37% | Peso weakened; near 52w low (3,122) |
| 52-week USD/COP range | 3,122–4,053 | — | Close is −22.7% vs 52w high of 4,053 |
| Key technical level | 3,200 (round number) | — | Psychologically important resistance for USD/COP |
The COLCAP’s 0.31 per cent dip was modest, and the intraday range is not published in the scan, so the close is the cleanest read. More telling is where the index sits: at 2,384.67 it is not testing any widely-watched floor, which keeps the move firmly in drift territory.
In the currency market, the peso’s decline lifted USD/COP to 3,158, keeping the exchange rate about 0.4 per cent above its 52-week low of 3,122—the level at which the peso had been strongest. Traders often view the round 3,200 mark as a psychological line where buyers and sellers start jostling more actively, and with the rate sitting below it, 3,200 now stands as the first resistance overhead.

03 Why it moved — a slump in crude meets a quiet local calendar
Oil prices, the traditional anchor for the Colombian market given the country’s reliance on crude exports, fell hard: Brent shed 4.73 per cent and WTI 5.11 per cent. Colombia is a significant oil exporter, and Ecopetrol, the state-controlled energy giant, is the single largest influence on both the COLCAP and the peso—so a move of that size in crude is the first place to look for Monday’s softness in Colombian shares.
Monday’s US trading saw the S&P 500 gain 1.48 per cent and the Nasdaq jump 2.13 per cent, a sign that global risk appetite was alive. Yet that enthusiasm did not travel to Bogotá, where local investors appeared content to wait for the release of the central bank’s monetary-policy minutes, due later on Tuesday, for clues on the interest-rate path.
Seasonal factors did the rest. Early August is a period when trading desks across Latin America thin out, and with no major corporate headlines out of Bogotá, there was little to pull the index in either direction beyond the commodity tape. The result was a session that felt less like a considered sell-off and more like a collective shrug.
In the currency market, the slight peso weakness was consistent with a modestly firmer US dollar, as the DXY index—which measures the greenback against a basket of major currencies—was little changed. Even with crude sharply lower, the peso gave up only 0.37 per cent, holding close to the strong end of its annual range alongside its emerging-market peers.
04 The day’s movers
| Driver | Level / Move | Change | Note |
|---|---|---|---|
| Tecnoglass | US$46.76 | +7.64% | Top mover; led the board by a wide margin |
| Southern Copper | US$185.91 | +1.75% | Andean miner; copper strength offset the slide in crude |
| Buenaventura | US$30.47 | +0.63% | Precious-metals peer; modest gain |
| Grupo Aval | US$5.24 | −0.76% | Financial holding drifted lower with the banks |
| Ecopetrol | US$16.60 | −1.01% | Most active name; 2,372,149 shares as crude fell |
| Credicorp | US$395.79 | −1.20% | Regional lender lower with the Andean financials |
| Bancolombia | US$91.07 | −1.57% | Colombia’s biggest bank; 304,196 shares traded |
The board was active, not empty: nine names changed hands, three of them higher and six lower. Ecopetrol was by far the busiest, with 2,372,149 shares going through as it slipped 1.01 per cent to US$16.60—a direct read-across from the day’s slump in crude. Bancolombia, the second heavyweight, fell 1.57 per cent to US$91.07 on 304,196 shares, and Grupo Aval eased 0.76 per cent to US$5.24.
Tecnoglass was the day’s standout, jumping 7.64 per cent to US$46.76—comfortably the largest move on the board and the main reason the advancing column was not empty. Among the wider Andean names tracked alongside Colombia, Southern Copper added 1.75 per cent to US$185.91 and Buenaventura 0.63 per cent to US$30.47, while Credicorp gave back 1.20 per cent to US$395.79.
05 The regional scoreboard
| Index | Country | Change |
|---|---|---|
| Ibovespa | Brazil | 0.00% |
| IPC | Mexico | −0.35% |
| IPSA | Chile | +0.30% |
| Merval | Argentina | −0.51% |
| S&P/BVL Peru General | Peru | — |
The Latin American board was split. Chile’s IPSA, the Santiago exchange’s benchmark for large, liquid shares, rose 0.30 per cent—a subtle nod to investors finding value in Andean equities. Mexico’s IPC fell 0.35 per cent, and Argentina’s Merval gave back 0.51 per cent, even as the US tape rallied.
Brazil’s Ibovespa, the region’s deepest equity market, was flat at 178,000 points. The lack of direction from Brazil, often a bellwether for Latin American risk appetite, reinforced the sense that Monday was a holding pattern. Peru’s index move could not be verified and is noted with a dash. The live market board embedded above carries all the closing figures for a quick scan.
06 The technical picture
The COLCAP’s drift to 2,384.67 keeps it well away from the extremes of its recent range. With the move driven by two heavyweights rather than by a broad repricing, no support or resistance level was seriously tested—the index is idling inside its range rather than probing a boundary.
For the currency, the technical story is clearer. USD/COP is within a hair’s breadth of its 52-week low of 3,122—the dollar’s weakest level against the peso over the past year. A break below that could bring the psychological 3,100 handle into focus quickly. A bounce, meanwhile, could push the rate back toward the 3,200 zone that traders often watch as a first resistance.
07 What to watch
- Banco de la República minutes: The central bank’s monetary-policy minutes, due Tuesday evening, could reset rate expectations and jolt the peso and bank shares into action.
- Oil price direction: Brent’s 4.73 per cent slide already showed up in Ecopetrol; whether crude steadies will decide how much further the peso and the energy-heavy COLCAP have to give.
- Breadth on the local board: Six of the nine names traded fell on Monday; a second session with decliners well ahead of advancers would turn a drift into a trend.
- Global risk mood and the DXY: The firm US dollar and the rally in US equities create a cross-current; a decisive DXY move could force the peso’s hand while local equities mark time.
