Today’s Focus
The COLCAP — Colombia’s benchmark stock index, a basket of the most liquid shares on the Bogotá exchange — closed at 2,576 points, down 0.33% on Monday. It opened higher but could not hold the gains.
The peso had the weaker day. The peso closed at 3,362 per US dollar, about 1.5% weaker than on Friday. Spot volume was about US$1.58 billion.
The drivers were external. US Treasury yields rose, oil prices climbed and global risk appetite faded. Local investors also weighed the government’s newly confirmed talks with the International Monetary Fund.
What matters today. The peso has given back part of its recent strength ahead of Wednesday’s central bank decision, while equities are drifting rather than breaking down.

01 The session in one read
Colombia’s main stock index, the COLCAP, fell 0.33% to 2,576 points on Monday, 28 September. It opened in positive territory, then turned lower as selling spread across global markets.
The peso weakened. The peso closed at 3,362 per US dollar, down from 3,312 on Friday. The day’s low was 3,302 and the high was 3,368.
The mood was cautious. Investors are waiting for the central bank’s interest rate decision on Wednesday and for more detail on the IMF talks.
Both the peso and local equities fell on the same day, which points to a common external driver rather than a domestic shock. Higher US yields and a jump in oil prices pushed investors away from emerging-market assets. The variable to watch is Wednesday’s rate decision: a surprise increase could support the peso but weigh on bank shares.

03 Why it moved — yields, oil and IMF headlines
The peso weakened as US Treasury yields rose and risk appetite faded across emerging markets. Brent crude futures rose about 0.9% to around US$105 a barrel, adding to inflation worries.
At home, the government confirmed it has begun talks with the International Monetary Fund as fiscal pressures mount. President Abelardo de la Espriella told Finance Minister Miguel Gómez Martínez and the economic team to take charge of the talks. Officials say it is too early to discuss the size of any financing. These are early talks. No loan, facility or agreement has been announced.
Wall Street also set a weak tone. The S&P 500 fell 0.77%.

06 The technical picture
For the COLCAP, the session settled nothing. The index slipped from Friday’s 2,585 but stays near the upper end of its recent range.
For the peso, the 3,300 level held as a floor for the dollar on Monday. A move back below it would point towards the year’s strongest levels near 3,044. A move above 3,400 would signal a deeper correction.
07 What to watch
- Central bank decision: Wednesday’s rate announcement. The rate is 12.00% and most analysts surveyed expect a hold.
- Peso levels: Whether the rate stays above 3,300 per US dollar or climbs towards 3,400.
- IMF talks: Any detail on financing or conditions could move bonds and the peso.
- Oil prices: Brent near US$105 a barrel supports Ecopetrol but adds to inflation risk.
