US Midterms Put Energy Prices in the Spotlight as Oil Markets Look Beyond the Pump

As Americans vote in the 2026 midterm elections, falling oil prices offer the Trump administration some relief. But gasoline and diesel remain expensive, exposing the limits of political influence over a global commodity market.

Energy prices have become one of the most visible tests of the US administration's economic record. As Americans head to the polls on November 3, oil has retreated from recent highs, gasoline prices have started to fall and Washington has renewed its emphasis on energy affordability.

But the relief at the pump remains incomplete. On November 2, the national average for regular gasoline stood at $4.17 per gallon, according to AAA. That was down from $4.40 a month earlier, but still substantially above the $2.98 recorded on February 28, when the US-Israeli war with Iran began. Diesel remained around $6.29 per gallon.

The political problem is straightforward: voters experience the price at the pump, not the price of Brent futures. And the two do not always move together.

For commodity markets, the midterms raise a more consequential question. How much influence does Washington really have over energy prices when the supply chain stretches from Middle Eastern oilfields and international shipping routes to US refineries and regional fuel markets?

The Disconnect Between Oil and the Pump

Falling crude prices do not necessarily mean falling fuel prices. The difference lies in the economics of refining and the availability of finished products.

Crude is only one component of the price of gasoline and diesel. Refining margins, inventories, transportation costs and regional supply conditions can all prevent lower feedstock costs from translating into cheaper retail fuel.

That distinction has become particularly important this year.The US Energy Information Administration reported that gasoline crack spreads in New York Harbor had averaged approximately $1 per gallon above their 2025 levels since May. Disruptions to refining operations in Russia, China and the Middle East tightened international product supplies, supporting US export demand and wholesale prices.

Diesel has been under even greater pressure. Since March, New York Harbor diesel crack spreads have averaged 74 cents per gallon more than gasoline crack spreads, while US distillate inventories were 14% below their five-year average in the week ending August 28.

This is the part of the energy market that political messaging often overlooks. A government can encourage domestic production, influence sanctions and release strategic reserves. It cannot immediately create additional refining capacity, replenish depleted inventories or make international shipping routes commercially viable again.

The distinction also explains why companies operating across multiple parts of the supply chain have an advantage. Access to crude is valuable, but so are refining relationships, storage, freight capacity and the ability to redirect products when regional markets become dislocated.

Hormuz Is a Bigger Variable Than Congress

The Strait of Hormuz remains a more immediate determinant of energy-market conditions than the composition of Congress.

The conflict involving Iran has demonstrated how quickly geopolitical disruption can affect physical commodity flows. Even when diplomatic developments trigger sharp declines in oil futures, uncertainty over shipping, insurance, export availability and the restoration of disrupted supply can keep physical markets under pressure.

The consequences extend beyond crude.

Diesel is particularly important because it connects energy markets to the wider economy. Freight operators, agricultural producers, mining companies and manufacturers all depend on reliable supplies of distillate fuel. Higher diesel costs feed into the cost of moving commodities, operating equipment and delivering finished goods.

For the US, domestic oil production offers some insulation, but not immunity. American producers remain exposed to international benchmarks, while refiners depend on crude quality, infrastructure and access to regional and international product markets.

This is where physical trading capabilities become commercially important. When supply routes are disrupted, the ability to secure alternative cargoes, arrange shipping and deliver products into markets experiencing shortages can become more valuable than simply having exposure to rising oil prices.

For the firms assessed by the GCT Index, these capabilities are central to competitive positioning. Market power, logistics and operational scale determine how effectively trading houses respond when geopolitical events reshape physical flows.

What the Midterms Could Change

The election will determine how much legislative support the Trump administration has for its energy agenda during the final two years of its term.

A Republican victory would generally give the administration greater scope to pursue its priorities on fossil-fuel development, permitting and deregulation. Democratic control of either chamber would increase congressional scrutiny of energy policy, federal spending, sanctions and government support for domestic critical-minerals projects.

The implications for commodity markets would be significant but not immediate.

Permitting changes and investment incentives can influence future production and infrastructure. Sanctions enforcement can alter trade flows. Support for domestic mining and mineral processing can reshape longer-term supply chains. But none of these measures can quickly resolve a shortage of refined products or reopen a disrupted shipping corridor.

The election also comes at a time when energy security is becoming increasingly difficult to separate from trade policy. The US administration's approach to Iran, relations with major oil producers and the strategic importance of critical minerals will all influence the commercial environment for commodity companies.

For trading houses, the key consideration is not which party wins individual races. It is whether the resulting political environment changes the rules governing access to supply, international trade and investment in infrastructure.

The Market Will Deliver Its Own Verdict

Gasoline prices make an effective political indicator because consumers see them every day. But they are an incomplete measure of the health of the energy market.

Crude prices can fall while diesel remains expensive. Domestic production can increase while regional product shortages persist. Diplomatic progress can remove a geopolitical risk premium without immediately restoring physical supply.

That is why traders will be watching more than the election result. Refinery margins, distillate inventories, tanker availability, freight rates and actual export volumes will offer a better indication of whether energy markets are genuinely normalising.

The midterms may determine the political direction of US energy policy. They will not determine the price of every barrel, cargo or gallon.

Washington can influence the conditions under which energy is produced and traded. The physical market ultimately determines what gets delivered, where it goes and what it costs.
