While South Korea surged 55% and Taiwan hit all-time highs, the iShares MSCI Colombia Capped ETF (COLO) quietly became the worst-performing country ETF in the world over the past month. The fund has shed -7.86% since the Iran war began on February 27 — underperforming the MSCI ACWI by more than 13 percentage points in a period when the global benchmark gained 5.8%.

The underperformance is not the result of a single shock. It is the accumulation of a structural condition that made Colombia unable to participate in either of the two dominant trades of 2026: the energy exporter rally of March, and the ceasefire recovery of April.

The Two Trades Colombia Missed

The Iran war created a clear binary in country ETF performance. Energy exporters gained as Brent topped $100. Energy importers fell as the Hormuz blockade raised costs. Then the ceasefire reversed the trade: energy importers recovered sharply, tech-heavy markets hit all-time highs, and risk appetite flooded back into cheap valuations.

Colombia sits in an uncomfortable position relative to both narratives. It is an oil exporter — Ecopetrol, the state-controlled oil company, is almost certainly COLO's largest holding at approximately 18.8% of the fund. By the logic of the March trade, Colombia should have gained as Brent rose. It didn't — not meaningfully. By the logic of the April recovery, Colombia should have participated in the broader EM risk-on rally. It didn't — it fell.

The explanation for both failures is the same: Ecopetrol is not a free-market oil company. It operates under the policy constraints of the Petro administration, which has pursued an energy transition agenda at odds with the capital expenditure and dividend maximisation that drove Norway's Equinor and Brazil's Petrobras higher during the oil spike. When Brent rises, Ecopetrol's theoretical revenue upside is partially captured by the government and partially constrained by Petro's restrictions on new exploration. The market has consistently discounted Ecopetrol's earnings relative to international oil price moves — and that discount is precisely why COLO failed to rally during March's oil shock.

What COLO Actually Holds

The iShares MSCI Colombia Capped ETF tracks 30 Colombian securities with $120 million in assets under management — one of the smallest country ETFs in the database by AUM, and one of the least liquid. The top holding at approximately 18.8% is almost certainly Ecopetrol (EC), Colombia's state-controlled oil giant. The next nine positions are a combination of Colombian financial institutions — Bancolombia, Grupo Aval, Davivienda — and industrial conglomerates, with Parex Resources (PXT.TO, 3.4%) as the only internationally cross-listed oil producer in the visible holdings and Tecnoglass (TGLS, 3.2%) as the lone US-listed industrial.

The portfolio's structure creates a specific vulnerability: Colombian banks are the second-largest exposure after Ecopetrol, and Colombian bank profitability is directly linked to the health of the domestic economy — which has been under pressure from President Gustavo Petro's fiscal policies, a widening primary deficit and a peso that has depreciated materially against the dollar over his administration. When the peso weakens, EWZ's USD-denominated returns amplify to the downside for international investors.

The Petro Administration Premium — Or Discount

Gustavo Petro became Colombia's first left-wing president in 2022. The market has consistently applied a risk premium to Colombian equities since his election — a discount that reflects three concerns that have not been resolved.

Oil exploration moratorium: Petro has signalled an intent to halt new oil exploration contracts as part of an energy transition policy. Colombia's proven oil reserves are relatively limited at approximately 2 billion barrels. If new exploration is curtailed, Ecopetrol's production trajectory declines in the medium term, compressing its long-term valuation regardless of current oil prices. The market is pricing Ecopetrol on a declining reserve base, not on current Brent — which explains why COLO didn't fully capture March's oil spike.

Fiscal trajectory: The Petro administration expanded social spending materially, widening Colombia's fiscal deficit. The primary deficit trajectory has put the Colombian peso under sustained depreciation pressure, which directly erodes the USD returns of COLO. With elections approaching in 2026 — either Petro seeking reelection or a successor campaign — the fiscal uncertainty is compounding, not resolving.

Dividend and capex tension: Ecopetrol has been caught between government demands for high dividend payouts (to fund social programs) and the capital expenditure requirements of maintaining production. A company simultaneously pressured to maximise dividends and invest in production maintenance is structurally constrained from doing either optimally — and international investors price that constraint.

The Valuation: Genuinely Cheap, Genuinely Risky

COLO at 8.85x forward P/E — a 51% discount to the MSCI ACWI (18.07x) — is among the cheapest country ETFs in the world. The 7.32% dividend yield is the highest of any country ETF in the CountryETFTracker database, driven by Ecopetrol's and Bancolombia's distribution policies.

The cheapness is real. The discount, however, reflects genuine structural risks that cheap valuations alone do not resolve — a lesson that every value-oriented EM investor eventually learns. A 7.32% dividend yield sounds compelling until the peso depreciates 15% against the dollar in the same period, erasing the income return and then some in USD terms. COLO's discount to the ACWI has been persistent for years — it is not a cyclical compression waiting to reverse, but a structural pricing of Colombia-specific political and fiscal risk.

Seasonality: May Offers No Structural Support

COLO's historical seasonality provides little near-term optimism:

May is seasonally neutral (+0.53% avg, 58% win rate across 17-19 years of data) — neither a tailwind nor a headwind. The seasonal pattern provides no catalyst for a near-term reversal of April's underperformance. The next structurally positive seasonal window is January, which in 2026 produced COLO's best January return on record (+17.73%) — but that was driven by EM euphoria before the Iran war began, not by a structural Colombia narrative.

The Irony: The Worst Performer in a Global Bull Market

The most striking aspect of COLO's recent underperformance is its timing. Global equities are near all-time highs. The S&P 500 (SPY) is up 8.2% since the Iran war began. South Korea (EWY) is up 24.6%. Taiwan (EWT) is up 25.4%. Even Brazil (EWZ), which has its own Petrobras political problems, is down only 5% — less than Colombia.

COLO is not just lagging the winners. It has underperformed the MSCI ACWI by 13.6 percentage points in a period of broad global equity strength. The fund is negative in a market where 70%+ of country ETFs are positive. That is not bad luck — it is a structural allocation problem that reflects the interaction of three compounding headwinds: Ecopetrol's politically constrained oil upside, Colombian bank exposure to a weakening domestic economy, and a peso that amplifies losses for USD-denominated investors.

At $120M AUM, COLO is also one of the least liquid country ETFs in the database. The fund's small size means that institutional outflows — even modest ones — can move the price meaningfully. Spreads are wider, price discovery is less efficient, and the fund is more prone to tracking error in periods of market stress than larger country ETFs.

Frequently Asked Questions

Why didn't COLO rally during March's oil price spike if Colombia is an oil exporter?

Ecopetrol, Colombia's state-controlled oil giant and COLO's largest holding at approximately 18.8%, operates under the Petro administration's energy transition constraints. The government has signalled a moratorium on new oil exploration contracts and has simultaneously pressured Ecopetrol for high dividend payouts to fund social programs. The market therefore prices Ecopetrol on a structurally declining production trajectory and constrained capital allocation — not on current Brent. When oil rose above $100 in March, Ecopetrol's valuation uplift was discounted by these structural headwinds, preventing COLO from capturing the oil exporter rally that benefited Norway's ENOR and Brazil's EWZ.

Why is COLO's dividend yield so high at 7.32%?

The 7.32% yield reflects Ecopetrol's and Bancolombia's high dividend payout ratios — Colombian companies historically distribute a large proportion of earnings. However, the yield is also a function of COLO's depressed share price: as the ETF has declined, the dividend yield has risen mechanically. USD-denominated investors must also adjust the yield for Colombian peso depreciation, which has eroded real dollar returns over Petro's administration. A nominal 7.32% yield in a currency that depreciates 10% annually against the dollar produces a negative real return in USD terms.

What would reverse COLO's underperformance?

Three catalysts could reverse the structural discount: (1) a change in Colombian energy policy — either via election of a new president in 2026 who reverses Petro's exploration moratorium, or legislative override of key energy policy measures; (2) a sustained Brent rally above $90 that forces the market to reprice Ecopetrol's near-term revenue regardless of long-term exploration concerns; or (3) a stabilisation or strengthening of the Colombian peso that removes the currency drag on USD returns. None of these is imminent — the ceasefire trade is working against the Brent scenario, the political calendar is unclear, and the peso remains under fiscal pressure.
