Colombia Markets: COLCAP & the Peso — September 15, 2026
Key Facts
- Colombia’s benchmark COLCAP index closed the Monday 14 September session at 2,588.25 points, a marginal decline of 0.06% on the day.
- The Colombian peso slipped against the US dollar, with USD/COP ending at 3,091.66, a 0.59% move that snapped eight straight sessions of peso gains.
- Brent settled at US$105.68 a barrel after Saudi Arabia shut its East-West pipeline, keeping inflation and interest-rate nerves simmering across Latin America.
- Global stocks slipped with the S&P 500 falling 0.48% and the Nasdaq down 0.56%, as AI-related alerts and higher US Treasury yields weighed on risk appetite.
- Congress’s economic committees approved the COP 634.9 trillion headline amount (about US$205 billion) for the 2027 budget, while Ecopetrol named Camilo Barco acting president after Juan Carlos Hurtado resigned.
Today’s Focus
Colombia’s stock market took a breather on Monday, with the COLCAP index — the benchmark for the country’s largest listed companies — closing at 2,588.25 points, down just 0.06%. The session range was tight: a high of 2,604.56 and a low of 2,585.42.
The currency market was the livelier one. The peso slipped to 3,103.10 per US dollar, a move of 0.59% that ended eight straight sessions of gains, though the rate is still far below its 52-week high of 3,925.
The backdrop was nervous. US stocks fell, Brent settled at US$105.68 a barrel, and the yield on the 10-year US Treasury bond touched 5.01% intraday for the first time since 2023 before closing at 4.97% — all factors that normally rattle emerging markets.
What held things together was the sense that Colombia’s economy remains resilient, with oil revenue supporting the peso and local investors waiting for fresh signals from the US Federal Reserve.
What matters today. Colombia’s market moved sideways because oil strength supported the peso even as global risk appetite faded ahead of the Federal Reserve’s rate decision.
01 The session in one read
Colombia’s stock market was a study in patience on Monday, as the COLCAP — the benchmark for the country’s biggest listed companies, such as Ecopetrol and Bancolombia — closed at 2,588.25 points, down 0.06% on the day. The index traded in a narrow range between 2,585.42 and 2,604.56.
The peso, meanwhile, gave a little ground. The US dollar rose 0.59% against the Colombian currency to end at 3,103.10 pesos, ending an eight-session run of peso strength.
The global mood explains it. The S&P 500 lost 0.48% and the Nasdaq fell 0.56%, while the US 10-year Treasury yield touched 0.56% intraday before closing at 4.97%, its highest in three years. When American government bonds pay near 5%, money leaves emerging markets.
For Colombia, the counterweight is oil. Brent settled at US$105.68 a barrel after Saudi Arabia shut its East-West pipeline, and that is quietly supporting both the peso and the government’s revenue outlook.
The COLCAP’s 0.06% decline is a rounding error. The peso’s 0.59% loss matters more, because it ended eight straight sessions of gains. Local shares did not fall further even with US equities slipping and Treasury yields touching 5%. That points to decent underlying demand for Colombian assets. The variable to watch is whether Brent holds above US$100 and whether the Federal Reserve signals higher rates for longer.
02 The day’s numbers
| Measure | Level | Change | Read |
|---|---|---|---|
| COLCAP (Bogotá benchmark). | 2,588.25 | −0.06% | Flat day near record high. |
| USD/COP (peso) | 3,092 | −0.32% | Peso slips, still far below 52-week high. |
| 52-week range (COP). | 3,044 – 3,925. | — | Peso well off worst levels. |
| Intraday range (COLCAP). | 2,585.42 – 2,604.56. | — | Tight, low-volatility session. |
| US 10-year Treasury yield. | 4.97% | +0.19 pp | Touched 5.01% intraday, a three-year high. |
The most striking number for foreign investors is the peso’s positioning. At 3,103.10 per dollar, the currency sits 20.9% below its 52-week high of 3,925 — a large improvement that reflects oil’s rally and a calmer political backdrop.
The COLCAP’s gentle decline of 0.06% was so small it hardly signals conviction. Traders were clearly waiting rather than betting, with one eye on Wednesday’s Federal Reserve decision. Rio Times · Live Market Intelligence

03 Why it moved — oil strength on one side, Fed nerves on the other
Oil is the anchor for Colombia’s market, and Brent holding above US$100 per barrel after last week’s 9% surge gave the peso a tailwind. Colombia is a significant oil exporter, so pricey crude means more dollar revenue flowing into the economy.
That support was offset by the global bond market. The US 10-year Treasury yield closed at 4.97% after touching 5.01% intraday, its highest in three years, making dollar assets more attractive and pulling money away from emerging markets like Colombia.
Bogotá trades again on Tuesday, September 15, with Ecopetrol’s extraordinary shareholders’ meeting the local event of the day. Local news had already added a layer of caution. The economic committees of both chambers approved the 634.9 trillion peso headline amount (about US$205 billion) for the 2027 budget, with the detailed bill still to be voted article by article before the end of September. At Ecopetrol, Alfonso Camilo Barco Muñoz was named acting president from September 15 after Juan Carlos Hurtado, himself an interim standing in for Ricardo Roa, resigned. Neither development moved the market strongly.
The combination left the COLCAP within a fraction of its recent all-time high of 2,627.05, but unwilling to push decisively higher until the Federal Reserve’s next move is known.
04 The day’s movers
| Driver | Level / Move | Change | Note |
|---|---|---|---|
| COLCAP index | 2,588.25 | −0.06% | Turnover thin; no standout stock data. |
| Peso (USD/COP) | 3,092 | −0.32% | Eight-session winning run ends. |
| US 10-year Treasury. | 4.97% | +0.19 pp | Rising yields cap local equity gains. |
| VIX volatility index. | 17.10 | +7.95% | Global nerves rising into Fed meeting. |
Per-stock data for Colombia was not available in the verified scan on Monday, so the real movers were at the macro level. The peso’s 0.59% slip to 3,103.10 per dollar was the standout, because it ended eight consecutive sessions of gains.
The oil story still runs underneath. Colombia’s currency is more sensitive to crude prices than Brazil’s or Mexico’s, and with Brent at US$105.68, the peso has structural support that most regional peers do not enjoy right now.
05 The regional scoreboard
| Index | Country | Change |
|---|---|---|
| COLCAP | Colombia | −0.06% |
| Ibovespa | Brazil | −0.91% |
| IPC | Mexico | +0.46% |
| IPSA | Chile | +1.09% |
| BVL Perú | Peru | −0.92% |
Chile was the clear regional winner, with the IPSA jumping 1.09%, while Brazil’s Ibovespa lagged with a 0.91% fall. Colombia sat in the middle, barely changed.
The mixed picture reflects how country-specific factors — copper in Chile, politics in Brazil, oil in Colombia — still dominate over any single regional story. A live whole-market board above carries the official closes for all five markets.
06 The technical picture
The COLCAP’s close of 2,588.25 leaves it just below its all-time high of 2,627.05 reached earlier in September. The tight intraday range on Monday suggests neither buyers nor sellers had enough conviction to push the index anywhere meaningful.
For the peso, the chart is more encouraging. USD/COP at 3,103.10 sits far below the 52-week high of 3,925 and near the lower end of its 3,044–3,925 band, which technical analysts would still call strong momentum for the Colombian currency.
The key technical level to watch is 3,044 on USD/COP — that is the 52-week low and the next major support if oil pushes higher. On the COLCAP, breaking above 2,627 with volume would signal a fresh leg up.
07 What to watch
- Federal Reserve decision: the US central bank meets on 16 September — any hawkish surprise could hit the peso and lift USD/COP sharply
- Oil price stability: Brent at US$105.68 supports government revenue and the peso, but a drop would expose the currency
- Ecopetrol leadership transition: Shareholders meet on Tuesday, September 15 to vote on five new board members, with Camilo Barco taking over as acting president that day
- Colombia inflation data: annual inflation at 6.24% remains above target, keeping pressure on the central bank
