The Big Three
The MSCI COLCAP fell 0.86% to 2,232.90 on Friday — the eighth decline in nine sessions — as the First Conference on Transitioning Away from Fossil Fuels opened in Santa Marta with over 50 nations and Petro announced Colombia’s withdrawal from Investor-State Dispute Settlement (ISDS) treaties. The index opened at 2,252.27, touched a marginal high of 2,267.91, then sold off to a session low of 2,231.19 before closing at 2,232.90. The nine-session decline from 2,332 (April 16) now totals −4.25% (99.10 points). The close at 2,232.90 is the lowest since the first week of March, with the index well below the Ichimoku cloud and every moving average. The MACD histogram deepened to −7.19 and the RSI signal fell to 41.99 — the deepest bearish readings of the cycle.
Petro’s announcement that Colombia will withdraw from ISDS — the mechanism that allows foreign investors to sue governments for policy decisions affecting their profits — is the single most hostile signal to foreign investment protection since the 2022 tax reform. ISDS cases in oil, gas, and mining accounted for 45% of new claims filed in 2025, with fossil fuel companies reaping at least US$100 billion in awards historically. By withdrawing, Petro removes the legal shield that protects foreign investors from policy expropriation — precisely as the Santa Marta conference explicitly excludes fossil fuel lobbyists and targets a global phaseout roadmap. For the COLCAP, the ISDS withdrawal compounds the FDI collapse documented last week: not only is investment declining, but the legal framework protecting existing investment is being dismantled 37 days before a new president takes office.
The Santa Marta conference (April 24–29) is Petro’s capstone legacy event — and it is directly market-negative for Ecopetrol and the hydrocarbon sector that anchors the COLCAP. Environmental Minister Irene Vélez Torres told The Guardian that the US, China, Russia, India, and Japan — the world’s largest polluters — are “not the space for them.” The conference will produce a “menu of solutions” for phasing out fossil fuels, with a ministerial high-level segment April 28–29 where Petro is expected to speak. For a country that depends on crude exports for a substantial share of government revenue, hosting a global anti-fossil-fuel summit while simultaneously withdrawing from investment protection treaties creates a paradox that the next president must navigate: Petro is locking in policy commitments that constrain his successor’s freedom to reverse course.

02 Equities — The Ninth Session
COLCAP Colombia today enters Monday’s session at 2,232.90 — the lowest level since early March — after the eighth decline in nine sessions pushed the MSCI COLCAP further below the Ichimoku cloud. This Colombia stock market report covers a session where the Santa Marta conference’s opening and Petro’s ISDS withdrawal announcement added fundamental damage to an already technically broken index. This is part of The Rio Times’ daily coverage of Latin American equity markets.
The nine-session sequence from 2,332 to 2,233 is the most sustained directional decline the COLCAP has produced in 2026. The breakdown started with the 200-day SMA failure (April 21), was confirmed by the MACD bearish cross (April 22), deepened through the cloud bottom (April 23), and has now been compounded by the ISDS withdrawal and the Santa Marta conference (April 24). Each session has added a new layer of damage: technical, then momentum, then structural, then institutional. The COLCAP is not just in a technical downtrend — it is repricing the cumulative policy framework deterioration under Petro’s final weeks in office.
The lower Bollinger Band at 2,201.35 is the immediate downside target — roughly 1.4% below Friday’s close. The March correction low zone near 2,150–2,180 is the deeper support. The long-term trendline near 2,100 is the structural floor. Without a catalyst — a polling shift, an oil spike, or a BanRep signal — the COLCAP has no technical reason to stop declining. Every indicator is bearish, the policy framework is deteriorating, and the election remains unresolved.
03 ISDS Withdrawal — The Investment Shield Removed
Petro’s announcement that Colombia will withdraw from Investor-State Dispute Settlement treaties removes the legal mechanism that has protected foreign investors for decades. ISDS allows investors to sue governments in international arbitration for policy decisions — including environmental regulations, tax changes, and exploration moratoria — that affect their profits. Fossil fuel and mining companies accounted for 45% of new ISDS cases in 2025, and the average award in fossil-fuel arbitrations is $600 million. By withdrawing, Petro removes the deterrent against future policy expropriation — a signal that foreign capital in Colombia’s energy and mining sectors is exposed to policy risk without legal recourse.
The timing amplifies the damage. The ISDS withdrawal, the Santa Marta conference (where fossil fuel lobbyists are explicitly excluded), the FDI collapse to Q1 2021 lows, the 23% minimum wage increase, the BanRep operational paralysis, and the fiscal rule suspension through 2027 — these are not isolated events. They are the final-month policy acceleration of a president who knows his time is running out. The next president inherits a policy landscape where investment protection has been dismantled, the central bank is operationally paralyzed, the fiscal rule is suspended, and a global anti-fossil-fuel commitment has been made in Colombia’s name. Reversing even a fraction of this requires congressional action, treaty renegotiation, and years of institutional rebuilding.
04 The Election — 37 Days
Polymarket (latest): Valencia 42%, Cepeda 36%, “Candidate M” 49.5%. The first round on May 31 is 37 days away, with a June 21 runoff almost certain. The market needs a decisive polling signal — Valencia pulling ahead in runoff scenarios by a margin that makes the outcome predictable — to produce a sustained rally. Until that signal arrives, the COLCAP is trading the policy deterioration rather than the election hope. The Santa Marta conference’s high-level segment (April 28–29, where Petro is expected to speak) could produce further policy commitments that the next president must navigate.
05 Technical Analysis — MSCI COLCAP Daily
From the chart: O:2,252.27, H:2,267.91, L:2,231.19, C:2,232.90 (−19.37, −0.86%). Friday’s candle is a bearish bar that closed near the session low — continuing the pattern of each day’s close near the bottom of the range. The index is now 50 points below the cloud bottom (2,257.76) and 30 points below the 200-day SMA (2,262.35). Every Ichimoku level, every Bollinger Band except the lower, and every moving average except the 200-day are now distant above.
MACD at 9.32 with signal at 2.13 (histogram −7.19) continues to deepen the bearish cross. RSI at 53.50 with signal at 41.99 has the signal well below 50 — the deepest bearish RSI reading of the cycle. The lower Bollinger Band at 2,201.35 is the immediate target. Below that: the March correction low zone at 2,150–2,180 and the long-term trendline near 2,100.
06 Key Levels
| Level | MSCI COLCAP |
| Cloud top (distant resistance) | 2,276.80 |
| 200-day SMA (resistance) | 2,262.35 |
| Cloud bottom (resistance) | 2,257.76 |
| Friday Close | 2,232.90 |
| Lower Bollinger Band | 2,201.35 |
| March correction low zone | 2,150–2,180 |
| Long-term trendline | ~2,100 |
07 Looking Ahead
Monday opens with the Santa Marta conference’s high-level ministerial segment (April 28–29) beginning this week — any further Petro commitments on fossil fuel phaseout or exploration bans would be directly market-negative for Ecopetrol and the broader index. The BanRep late April meeting is the last domestic policy event before the campaign intensifies. The lower Bollinger Band at 2,201 is the near-term downside target. A close below 2,200 would open the path to the March correction low zone at 2,150–2,180.
Key dates: April 28–29 — Santa Marta ministerial high-level segment (Petro expected to speak). Late April — BanRep meeting (hold at 11.25%). May 31 — Presidential first round (37 days). June 21 — Runoff. Polymarket: Valencia 42%, Cepeda 36%.
08 Verdict
Friday was the session that added institutional damage to a technically broken index. Petro’s ISDS withdrawal — announced as 50+ nations gathered in Santa Marta for a conference that explicitly excludes fossil fuel lobbyists — removes the legal shield protecting foreign investors in Colombia’s energy and mining sectors. The COLCAP at 2,233 is now pricing four years of accumulated policy damage: the 2022 tax reform, the 2024 labor reform, the exploration halt, the 23% wage increase, the fiscal emergency, the BanRep paralysis, the FDI collapse, and now the ISDS withdrawal. The ninth session of decline (eight actual drops in nine days) has produced a −4.25% drawdown from the April 16 high with no stabilization signal.
Bias: Strongly bearish — no floor visible. The COLCAP at 2,233 is below the cloud, below the 200-day SMA, below the lower Bollinger Band proximity, and pricing the most hostile investment environment since Petro’s inauguration. The lower BB at 2,201 is the next target. The March correction lows at 2,150–2,180 are the deeper floor. The carry (11.25%) and the bond buyback ($4 billion) are structural positives that the equity market has stopped pricing. Only a decisive election polling shift (Valencia breakaway) or an oil spike can reverse the momentum. The Santa Marta ministerial segment this week creates further policy risk. Thirty-seven days to May 31. The COLCAP is in free fall.
