The Iran ceasefire announcement sent the IPC up 3.67% in a single session. But the ceasefire trade is not uniform across the region. Brazil loses its windfall. Colombia’s fiscal fragility resurfaces. Chile is the purest long. Here is the map.
On April 8, the United States and Iran announced a ceasefire. Brent crude dropped 10% in a day. The IPC posted its best session of 2026. Every LatAm index rallied. The reflex trade was simple: sell oil, buy risk. But the second-order effects diverge sharply across Latin America, and the market’s initial reaction treated the region as a monolith when it should have been pricing five different stories.
The oil shock from the Strait of Hormuz closure was the largest supply disruption in the history of the global oil market, per the IEA. Brent surged from $72 in late February to above $120 at its peak. The ceasefire, if it holds, brings Brent back toward the $80 to $90 range. That swing is massive, and it hits each Latin American economy through completely different channels depending on a single variable: is the country a net oil exporter or a net oil importer?
The IMF’s April World Economic Outlook, published this week, revised Latin America’s 2026 growth forecast to 2.3%. But that regional average obscures enormous dispersion. Brazil at 1.9%, Mexico at 1.6%, Colombia under pressure, Chile and Peru positioned to benefit. The ceasefire does not change these trajectories equally.
Brazil: the windfall reversal
Brazil is Latin America’s largest oil producer at roughly 3 million barrels per day. Petrobras, which represents approximately 25% of the Ibovespa’s weight, has been the primary beneficiary of the oil shock. Higher Brent means higher cash flow, higher dividends, and a stronger BRL on the commodity windfall.
The ceasefire reverses this. If Brent settles in the $80 to $90 range, Petrobras still operates profitably (its lifting cost is well below $30 per barrel), but the extraordinary cash generation of the $120 environment disappears. The dividend yield compresses. Foreign investors who bought Brazil as an oil hedge rotate out.
But here is what the market is underweighting: the ceasefire is net positive for domestic Brazil. The Selic at 14.75% is the most restrictive rate in any major EM. The BCB wants to cut but has been constrained by imported inflation from the oil shock. If Brent declines sustainably, the BCB’s path to easing opens. Brazilian banks (Itau, Bradesco), retailers (Magazine Luiza, Renner), and homebuilders (MRV, Cyrela) all re-rate on the expectation of lower rates. The rotation within the Ibovespa, from Petrobras to domestic rate-sensitives, is the higher-conviction trade than the index level itself.
Mexico: the Banxico unlock
We covered Mexico’s oil transmission in detail last week. The summary: equity exposure is minimal (Pemex is not listed, IPC oil weight under 1%), but the inflation channel is strong. CPI surged to 4.63% by mid-March on higher diesel and food transportation costs. Banxico cut to 6.75% on March 26 in a tight 3-2 vote, already pushing against the grain.
The ceasefire’s value for Mexico is not about oil revenue. It is about removing the inflation constraint on Banxico. If diesel prices retreat, CPI pressure eases, and the board can resume cutting without sacrificing credibility. The market expects 6.3 to 6.5% by year-end: two more 25 basis point cuts. A sustained oil decline makes that path feasible. A persistent spike above $100 makes it impossible.
The names that benefit most are the ones whose valuations are compressed by higher rates: Alsea (consumer discretionary, leveraged balance sheet that benefits from lower refinancing costs), the airport groups (jet fuel costs decline, travel demand normalizes), and Gentera (lending volumes expand when borrowing costs fall). WALMEX is a structural hold regardless: pricing power in any environment, defensive in a downturn, participation in any consumption recovery.
Colombia: the one that loses
This is the contrarian call in the region, and we want to be explicit about it.
Colombia is a net oil exporter. Ecopetrol, majority state-owned, is the country’s largest company and a critical source of fiscal revenue under President Petro’s spending agenda. The oil shock was a fiscal lifeline: higher Ecopetrol dividends and oil royalties partially offset the deficit widening that has been Colombia’s central macro risk since 2022.
The ceasefire removes that lifeline. If Brent falls back to $80 to $90, Colombia’s fiscal fragility resurfaces immediately. The country’s fiscal stance is what the IMF diplomatically calls a “weak spot,” and BanRep (the central bank) is still in tightening mode. Lower oil means lower COP, wider fiscal deficit, and potentially slower growth as government spending capacity shrinks.
Ecopetrol’s stock price, which rallied on the oil shock, gives back those gains. The broader Colcap index faces headwinds as the fiscal narrative returns. For international investors, the ceasefire is a reason to underweight Colombia relative to the rest of the region, not overweight it.
Chile: the purest ceasefire long in LatAm
Chile imports 100% of its crude oil. The Hormuz closure was an unmitigated negative: higher fuel costs, higher transportation inflation, and a BCCh (Banco Central de Chile) forced to pause its easing cycle. The CLP weakened as the energy import bill surged.
The ceasefire reverses every one of these channels. Lower oil directly reduces Chile’s import bill, eases inflation pressure, and lets the BCCh resume cutting. The CLP recovers. Retail names (Cencosud, Falabella) benefit from lower transportation costs and resumed consumer confidence. Utility names (Enel Chile) benefit from lower generation costs.
Chile also has a natural hedge that most LatAm economies lack: copper. If the ceasefire triggers a global risk-on rally, copper demand holds up, supporting Chile’s export revenue even as oil revenue (which it does not have) is irrelevant. The combination of lower energy costs and stable copper income makes Chile the most favorably positioned economy in the region for the post-ceasefire environment.
We think Chile is underowned by international LatAm allocators who have been overweight Brazil for the oil trade. The rotation opportunity is significant.
Peru: positive, but noisy
Peru is a net oil importer and a mining economy. Lower oil helps margins across the mining logistics chain (trucking, processing, port operations) and lets the BCRP resume its cautious easing. Credicorp, the country’s largest bank, benefits from lower rates through credit expansion.
But Peru has an idiosyncratic risk that the ceasefire does not resolve: political uncertainty remains elevated, institutional confidence is low, and mining investment decisions continue to be delayed by permitting challenges. The ceasefire trade in Peru is positive but smaller in magnitude than Chile, and the country-specific noise limits the conviction level.
The one caveat: gold. Peru is a major gold producer, and if the ceasefire triggers a sustained risk-on rally, gold prices could decline as safe-haven demand fades. Buenaventura and other gold-linked names may underperform even as the broader macro improves. Southern Copper (SCCO), by contrast, benefits from the risk-on copper bid and lower energy costs simultaneously.
How to position
LatAm ceasefire trade map
Oil position, shock impact, and what a sustained ceasefire means across five Latin American markets.
| Market | Oil position | Shock impact (Mar-Apr) | If ceasefire holds | Key names to watch |
|---|---|---|---|---|
| Brazil | Net exporter ~3mm bpd production | Petrobras cash flow surges. BRL supported by commodity windfall. But Selic at 14.75% already restrictive, and higher imported inflation complicates BCB's easing path. Ibovespa outperformed LatAm peers in March. | Petrobras loses Consumers win Oil decline hits Petrobras (25% of Ibovespa). But lower fuel costs accelerate BCB cuts, benefiting rate-sensitive domestics: banks, retail, homebuilders. | Petrobras (PETR4), Itau (ITUB4), Magazine Luiza (MGLU3), MRV (MRVE3) |
| Mexico | Mixed Producer but net refined importer | IPC fell 5.4% from ATH. Peso range 17.1-18.1. CPI to 4.63%. Banxico easing constrained. Fiscal math ambiguous: crude revenue up, but diesel/gasoline import costs rise. Equity transmission weak, inflation channel strong. | Broad positive Lower oil removes the inflation constraint on Banxico. Easing resumes, rate-sensitive names rally. Airports benefit from cheaper jet fuel. Consumption plays recover. | WALMEX, Alsea (ALSEA*), GAPB, OMA (OMAB), Gentera (GENTERA*) |
| Colombia | Net exporter ~750k bpd, Ecopetrol key | Ecopetrol windfall supports fiscal accounts under Petro's spending agenda. COP strengthened on oil. But BanRep still tightening, and fiscal credibility remains the weak spot. Colcap rallied on oil. | Ecopetrol loses Fiscal risk rises Oil decline exposes Colombia's fiscal fragility. Ecopetrol revenue falls, deficit widens. COP weakens. The ceasefire is net negative for Colombian equities. | Ecopetrol (EC), Bancolombia (CIB), Grupo Aval (AVAL) |
| Chile | Net importer 100% imported crude | CLP weakened as energy import bill surged. Inflation pressure from fuel and transportation. BCCh paused easing. Copper prices held up, partially offsetting the energy cost shock. | Clear winner Lower oil removes the binding constraint. BCCh resumes cutting. CLP recovers. Retail and utility names rally on lower energy costs. Chile is the purest ceasefire long in LatAm. | Cencosud, Falabella, Enel Chile, SQM (copper hedge) |
| Peru | Net importer Mining economy, not oil | PEN under pressure from imported inflation. BCRP paused cuts. Mining exports (copper, gold) strong, but fuel costs crimp margins for trucking and logistics. Political noise continues. | Positive Lower oil helps margins across mining logistics. BCRP can resume cutting. But gold decline on risk-on sentiment may offset some mining gains. Net positive for domestic names. | Credicorp (BAP), Southern Copper (SCCO), Buenaventura (BVN) |

The ceasefire trade in Latin America is not “buy LatAm.” It is a relative value trade across five economies with fundamentally different oil exposures.
The highest-conviction positions: long Chile (purest beneficiary of lower oil, BCCh easing, CLP recovery), long Mexican rate-sensitives (Banxico unlock), and long Brazilian domestics (rotate from Petrobras to banks and retailers). The underweight: Colombia (fiscal fragility resurfaces without the oil windfall). Peru is a conditional positive that requires conviction on the political environment.
Within Mexico specifically, the ceasefire resolves the uncertainty we flagged in our Five Trades article from January: Trade #1 (Banxico easing) gets back on track. Trade #5 (peso carry unwind risk from oil-driven inflation) fades. The two trades that depended on the macro environment stabilizing are now both constructive.
The bottom line
The Iran war stress-tested every assumption about Latin American markets. The ceasefire does not restore the pre-war status quo. It creates a new set of relative winners and losers based on oil exposure, central bank flexibility, and fiscal resilience.
Brazil and Colombia benefited from high oil. Mexico, Chile, and Peru were hurt by it. The ceasefire flips these positions. The investors who make money from here are the ones who recognized that “LatAm” is not a trade. It is five trades, and they just reversed.
