The war premium is gone.
On June 24 — the same day Venezuela’s earthquake killed 164 people and upended the hemisphere — U.S. crude oil tumbled nearly 4 percent to approximately $70 a barrel, reaching a pre-war low that reflected something more significant than a single day’s trading. It reflected a market finally pricing out the risk that the Iran conflict would permanently disrupt global energy supply.
The relief was real. But its distribution across Latin America was anything but equal.
The single shock split a continent. A flight to safety lifted the dollar and pressed hardest on the markets that had run furthest, while a parallel collapse in oil quietly rewarded the importers that buy their fuel abroad. Argentina wore the scars of the first force. Its Merval crashed 4.25 percent to about 3.11 million as MSCI kept the country in its lowest tier with no path to an upgrade — the climax of a roughly 11 percent three-day unwind.
Colombia’s COLCAP fell for a third straight day.
Mexico’s IPC slid to 66,278.
Brazil went the other direction entirely. Cheaper fuel feeds lower inflation in Brazil, and the market responded: the Ibovespa dipped just 0.44 percent — the regional outperformer — while the country pulled in a record $4.1 billion of foreign money in a single day. For a country running a restrictive policy rate of 15% and facing a presidential election on October 2, a falling oil price that simultaneously lowers inflation pressure and attracts foreign capital is the best possible macroeconomic news in the worst possible political moment.
The Winners
Brazil and Chile are the clearest beneficiaries of sustained lower oil prices. Both are net energy importers — Brazil despite its offshore pre-salt reserves still imports refined petroleum products — and lower crude prices reduce their import bills, ease inflationary pressure, and create space for central banks to accelerate rate cuts.
Goldman Sachs expects Brazil to cut interest rates by 2.5 percentage points to 12.5% — even at 12.5% the rate remains restrictive, but the direction matters for investment flows and consumer confidence heading into October’s election.
For Chile’s Kast government, which is already fighting a fiscal credibility battle after abandoning its zero-deficit pledge earlier this month, lower oil prices reduce energy import costs and provide a measure of relief on the inflation front — one less headwind for an administration that has plenty of them already.
Peru, the region’s fastest-growing major economy in 2026, sits in a more complex position. Its copper and gold exports are booming — commodity prices that have nothing to do with oil — and lower energy costs reduce its mining input costs. But Peru’s political crisis, with Fujimori and Sánchez separated by 24,000 votes and no certified result, means any macroeconomic tailwind is being absorbed by institutional uncertainty rather than translated into investment.
The Losers
Colombia and Venezuela face the sharpest downside from the oil price collapse — and for structurally different reasons that illuminate how fragile the region’s commodity dependency remains.
Colombia’s new president, Abelardo de la Espriella, takes office on August 7 with a promise to reopen the hydrocarbon sector, restart fracking, and generate fiscal revenues through expanded oil and gas extraction. He inherits that agenda at a moment when the commodity it depends on has just dropped to its lowest price since before the Iran war.
Colombia continues to face higher inflation due to structural imbalances, and fiscal deficits will remain significantly above historical averages. Lower oil revenues make the fiscal math harder before de la Espriella has even been sworn in.
Venezuela’s situation is categorically worse. The earthquake has transformed an already catastrophic fiscal position into an acute reconstruction crisis. Venezuela needs foreign capital, infrastructure investment, and debt relief at exactly the moment oil — the country’s primary potential revenue source in a post-sanctions environment — has dropped to $70 a barrel. The Rodríguez government’s ability to attract the foreign mining and oil investment its reconstruction depends on is now constrained by both the earthquake damage and the commodity price environment simultaneously.
The Broader Picture
The region’s top seven economies are projected to record GDP growth of 1.9 percent in 2026 — modest, but resilient against a backdrop of U.S. tariff pressure, political transitions, and now a natural disaster of historic scale.
The oil price collapse adds a new variable to that projection — one that will benefit the region’s net importers and punish its exporters for as long as the post-Iran-war price floor holds.
Latin America has always been a region where a single commodity price movement can simultaneously crown winners and devastate losers. June 24 was that day in 2026. The earthquake got the headlines. The oil chart told the economic story.
