The Briefing
- Diesel crossed $6.285 per gallon nationally for the first time in recorded history in mid-September — a milestone tied directly to the U.S.-Iran war that began February 28, now in its seventh month.
- Brent crude surged to $107 a barrel on September 10 during the conflict's biggest single-day escalation; prices have since eased to the 84–92 range, with Goldman Sachs warning of a return toward $120 if Hormuz disruptions persist.
- Mexico depends on the United States for roughly 75% of its natural gas and more than half its gasoline, making it directly exposed to every price movement at Gulf Coast refineries.
- 53% of registered Latino voters ranked inflation and cost of living as their primary concern in a spring survey conducted before diesel crossed $6.
- Brown University's Costs of War tracker now shows American households have paid approximately $107 billion more in fuel since February 28 — more than $776 per household on average.
Seven months into a tanker war that has reshaped global energy markets, the Strait of Hormuz conflict is no longer an abstraction for Latino families on either side of the U.S.-Mexico border. Diesel crossed $6.285 per gallon nationally for the first time in recorded history during the week ending September 14 — a milestone capping a sustained climb that began the day U.S. and Israeli forces struck Iran on February 28. With Brazil's presidential election set for Sunday, remittance-dependent families in Mexico and Venezuela already under strain, and Latino workers in the U.S. concentrated in fuel-reliant jobs, the Hormuz conflict has stopped being a geopolitical story and become a kitchen-table one.
How a 33-Mile Strait Became a Global Economic Emergency
The Strait of Hormuz — a narrow channel between Iran and Oman — carried roughly 20 million barrels of oil daily before the war disrupted flows, accounting for one-fifth of all global oil and gas trade. When U.S. and Israeli strikes hit Iran on February 28, Tehran responded within days by closing the strait to what it called unfriendly nations and ordering its Revolutionary Guard naval forces to attack commercial shipping.
IEA Director General Fatih Birol described what followed as "the largest supply disruption in the history of the global oil market," with losses in March alone exceeding those of the 1973 oil crisis. Seven months later, the violence has not de-escalated. Just last month, Iran's Revolutionary Guard struck tankers it accused of using unauthorized routes — direct retaliation after U.S. forces disabled the very large crude carrier Downy and the Suezmaz Stark I and destroyed a third vessel under Washington's retaliatory posture.
The September 9–10 wave of strikes — the biggest declared exchange of shipping attacks since the war began, with Iran targeting 10 vessels and the U.S. destroying five Iranian tankers — sent Brent crude surging to $107.08 a barrel, its highest point since late May. Prices have since eased into the 84–92 range as diplomatic signals multiplied, but analysts warn the calm may not last. Goldman Sachs has identified a scenario in which Brent could climb back toward $120 per barrel by the fourth quarter if Gulf output remains suppressed and Hormuz attacks resume in force.
Latino Workers Bear the Sharpest Edge of Record Fuel Costs
No segment of the U.S. workforce absorbs high pump prices more directly than Hispanic workers. Latinos represent roughly one in five people employed across the country and are densely clustered in construction, trucking, landscaping, and gig-platform driving — occupations where fuel is a cost the worker, not the employer, absorbs out of take-home pay.
When the Brown University Costs of War project first released its Iran War energy tracker in May, it found Americans had already paid more than $40 billion extra at the pump since the conflict started — about $300 per household. That figure has since grown dramatically. The live tracker now shows cumulative extra fuel spending approaching $107 billion, equivalent to more than $776 per American household — a burden that hits independent contractors and gig drivers, categories that over-index toward Latino workers, especially hard, since they have no employer reimbursement and no hedging buffer.
The economic pain carries political weight. According to the UnidosUS survey of 3,000 registered Latino voters released in late spring, 53% named inflation and the cost of living as their primary concern — surpassing jobs, housing, health care, and immigration. That survey predates the September diesel record by months.
Mexico Faces a Double Squeeze — at the Pump and in the Mailbox
Mexico is caught in a structural trap: it exports crude oil but depends on the United States for roughly 75% of its natural gas and more than half its gasoline, meaning price shocks at Gulf Coast terminals travel south within weeks. Tortilla producers have already flagged incoming price hikes. President Claudia Sheinbaum has acknowledged that inflation has climbed above the 3.7% rate recorded in 2025, while insisting prices remain manageable.
The less visible damage runs through the remittance channel. Remittances represent close to 4% of Mexico's GDP. When Latino workers in Houston, Chicago, and Los Angeles spend more at the pump, less reaches family members across the border — a compression that Economist Intelligence Unit analyst Cecilia Godoy says hits household budgets across net-import nations in Latin America clearly and negatively.
Venezuela's Transition Government Rides an Awkward Windfall
Venezuela presents the sharpest Latin American contradiction of this war. The transition government of acting President Delcy Rodríguez — which resumed crude shipments to U.S. buyers despite Venezuela's long alliance with Iran cultivated under Chávez — benefits from elevated global prices in the short term. But windfall petrodollars rarely trickle down quickly to a population still rebuilding from decades of economic collapse, while the Venezuelan diaspora in the United States faces the same fuel squeeze as every other low-income community, leaving less for remittances home.
Brazil Heads to the Ballot Box Sunday Carrying an Energy Hangover
Brazil's October 4 election takes place inside an economic picture complicated by seven months of war-driven price pressure. As a net crude exporter, Brazil gains revenue when Brent climbs — Petrobras posted net profits up 55% in the first half of 2026, with shares surging dramatically on the oil rally. But the country lacks the refining capacity to convert its own crude into enough diesel for domestic truckers — the backbone of a continent-sized logistics network — forcing those workers onto global pricing.
President Lula responded before the vote by announcing fuel subsidies for gasoline and diesel, but the move arrives against a backdrop of inflation running at a 4.47% annual rate per the most recent IPCA-15 reading — near the upper limit of the central bank's target band — and with Lula and challenger Flávio Bolsonaro separated by a razor-thin margin heading into Sunday's first round. Whether Brazilian voters separate Petrobras profits from grocery prices on Sunday may be the election's defining variable.
The Hormuz tanker war will not be on the ballot in Brazil. But its cost will be in every voter's pocket when they walk into the booth.
