US gasoline prices reach $1.09 per liter as oil trades at $76.80 per barrel

Gasoline prices across the United States have resumed an upward trend as renewed military hostilities in the Middle East heighten concerns over global energy supply security. This shift follows a period of localized price declines that briefly followed a temporary ceasefire agreement between Washington and Tehran last month.

The latest price volatility is tied directly to the deterioration of diplomatic relations in the Persian Gulf. President Donald Trump declared on 10 July 2026 that the interim ceasefire agreement with Iran is no longer in effect, despite assertions that both nations have agreed to continue negotiations. The uncertainty regarding the future of the Strait of Hormuz—a critical maritime artery through which roughly 20% of global energy flows pass—has rattled energy markets. Data from S&P Global Commodities at Sea indicates that tanker traffic through the strait fell to 34 ships on 9 July 2026, marking the lowest daily level since late June.

Market Indicators and Price Drivers

Crude oil serves as the primary benchmark for fuel costs, typically accounting for approximately 51% of the price of a gallon of gasoline. As of 6:15 a.m. Eastern Time on 10 July 2026, oil was priced at $76.80 per barrel. While oil prices experienced a slight retreat on Friday, the energy sector remains characterized by significant price swings. Refinery operations, tax policies, and seasonal demand further complicate the retail pricing structure.

According to the U.S. Energy Information Administration (Eia), the divergence between crude oil costs and pump prices is often measured by the "crack spread," an indicator of refinery profit margins. Disruptions to refinery infrastructure, such as those caused by military strikes on facilities in Russia or logistical constraints elsewhere, continue to place upward pressure on refined products like diesel, which is currently retailing at $1.210 per liter in the U.S.

Geopolitical Context and Industry Impacts

The collapse of the ceasefire has revived fears of a prolonged conflict. Beyond direct military engagements in the Gulf, the conflict has broader economic implications. Analysts at GasBuddy also point to the constraints posed by Moscow’s outright ban on diesel exports as a factor tightening the global fuel market, even as regional negotiators in Oman and Iran attempt to salvage diplomatic channels. Moscow’s response, layered on top of existing restrictions on gasoline and jet fuel exports, is intended to keep fuel supplies within Russia.

Domestic energy policy continues to play a role in how the United States manages these fluctuations. The utilization of the Strategic Petroleum Reserve remains an option for tempering supply shocks. Federal administration policies regarding drilling, including the move in 2025 to reopen more than 1.5 million acres in the Coastal Plain of the Arctic National Wildlife Refuge for oil and gas leasing, are frequently cited as long-term variables for future supply stability.

What to Watch Next

• Diplomatic Progress: Iranian Foreign Minister Abbas Araqchi is scheduled to travel to Oman on 11 July 2026 at the head of a delegation to hold talks on bilateral relations and the situation in the Strait of Hormuz.
• Refinery Output: Ongoing updates from the EIA regarding inventory levels remain critical in assessing whether domestic supply can offset the current reduction in global tanker throughput.

As the conflict continues into its fifth month, market participants are monitoring both the physical flow of oil through the Strait and the broader macroeconomic data. While markets have shown resilience in some sectors, the energy landscape remains deeply sensitive to the absence of a durable ceasefire agreement.
