What's Happening
In a significant diplomatic intervention with direct energy market consequences, former and current President Donald Trump publicly called on Ukraine to cease its drone and missile strikes targeting Russian diesel production and export infrastructure — stating explicitly that the attacks are causing a measurable global fuel shortage. The statement, reported by PBS on September 13, 2026, immediately reverberated through crude oil and refined products markets, where traders had already been pricing in elevated geopolitical risk premiums throughout the summer.
Russian diesel exports have been a persistent pressure point in global energy markets since the full-scale invasion of Ukraine began in February 2022. Ukraine's campaign to strike deep inside Russian territory — including refineries, fuel depots, and pipeline infrastructure — has periodically disrupted Moscow's ability to export diesel to Europe, Asia, and other markets. When Russian supply tightens, global diesel benchmarks rise, and because crude oil and refined products markets are deeply interconnected, gasoline prices follow.
Trump's statement carries weight beyond rhetoric. As president, his administration controls US diplomatic posture toward Ukraine, military aid packages, and the broader framework of Western sanctions on Russian energy. A shift in US policy that reduces pressure on Russian fuel infrastructure — or signals tolerance for resumed Russian diesel exports — could either calm markets by increasing supply expectations, or inflame them further if the statement is read as geopolitical instability. In the immediate hours after the PBS report, WTI crude futures moved higher by roughly 1.2 to 1.8 percent, reflecting trader uncertainty about what the statement signals for the medium-term supply picture. Brent crude, the global benchmark more sensitive to Russian export disruptions, saw a similar uptick. Diesel futures on the NYMEX heating oil contract — the closest US proxy for global diesel pricing — spiked more sharply, reflecting the direct supply concern Trump named.
For everyday drivers, this is not an abstract geopolitical story. It is a supply-chain event with a direct line to the price per gallon they will pay this week.
Data Snapshot
As of the week ending September 12, 2026, the AAA national average gas price stood at approximately $3.44 per gallon for regular unleaded, up roughly 6 cents from the prior week and 11 cents above the same period in 2025, according to AAA data. WTI crude oil was trading near $81.50 per barrel ahead of the Trump statement, with Brent crude at approximately $84.20 per barrel. Following the PBS report, WTI pushed toward $82.80 per barrel in after-hours trading — a move of about $1.30 per barrel, or roughly 1.6 percent.
According to EIA data, US commercial crude oil inventories drew down by approximately 2.1 million barrels in the most recent weekly report, tighter than analyst expectations of a 1.4 million barrel draw. Distillate fuel inventories — which include diesel and heating oil — fell by 1.8 million barrels, a notably large draw for this time of year that had already been pressuring diesel prices before Trump's statement added a new layer of uncertainty. The EIA's weekly retail gasoline price survey confirmed the upward trend, with the national average gas price for all grades averaging $3.51 per gallon as of the latest reporting week.
Why It Matters at the Pump
The connection between a geopolitical statement about Russian diesel and what US drivers pay for regular unleaded is real, measurable, and faster than most people expect. Here is the transmission mechanism: crude oil accounts for roughly 50 to 55 percent of the retail price per gallon of gasoline. When WTI crude rises by $5 per barrel, that translates — with a lag of one to three weeks — to approximately 10 to 12 cents per gallon at the pump. The $1.30 per barrel move seen immediately after Trump's statement is modest on its own, but it compounds an already-rising market.
Diesel's influence on gasoline prices is less direct but still significant. Refineries produce both diesel and gasoline from the same barrel of crude. When diesel margins are high — as they are now, with distillate inventories running below the five-year seasonal average — refiners have an incentive to maximize diesel output, which can reduce gasoline supply and push gasoline prices up independently of crude moves.
Regionally, the impact will not be uniform. California drivers, already paying a gas prices today average of approximately $4.65 per gallon due to the state's unique fuel blend requirements and refinery constraints, face the steepest absolute prices but are somewhat insulated from diesel-specific shocks because California's refinery mix skews toward gasoline. The Midwest, which relies heavily on pipeline-delivered diesel for agriculture and trucking, could see sharper diesel price spikes that eventually bleed into gasoline. The Gulf Coast, home to the nation's largest refining complex, typically sees the lowest retail prices — currently near $3.10 per gallon — but refinery margins there will widen if crude and diesel both rise. The Northeast, already dealing with tight home heating oil supplies ahead of winter, faces the most acute diesel vulnerability.
What's Driving This
The root cause is a collision of three forces: Ukraine's sustained infrastructure war against Russian energy assets, a global diesel market that entered September already undersupplied, and a US political intervention that has injected fresh uncertainty into how that supply picture resolves.
Ukraine's drone campaign against Russian refineries and fuel logistics hubs has been one of the most consequential — and underreported — energy market stories of 2025 and 2026. Russian refineries at Saratov, Ryazan, and Novoshakhtinsk have all suffered damage that reduced throughput. Russia's diesel export volumes to Europe fell by an estimated 15 to 20 percent in the first half of 2026 compared to the same period in 2024, according to tanker tracking data cited by Reuters. That tightness pushed European diesel benchmarks higher, which in turn pulled US diesel exports toward Europe — drawing down US distillate inventories faster than seasonal norms.
OPEC+ has not meaningfully offset this tightness. The cartel's current production framework, extended through the end of 2026, keeps voluntary cuts of approximately 2.2 million barrels per day in place among eight member nations including Saudi Arabia and Russia. Russia's own compliance with those cuts has been complicated by the infrastructure damage Ukraine has inflicted — making it difficult to separate voluntary restraint from forced reduction.
The IEA's most recent Oil Market Report flagged global diesel stocks as a key vulnerability heading into the Northern Hemisphere winter demand season, which typically begins lifting heating oil demand in October.
Historical Context
To understand whether this moment is unusual, it helps to benchmark it against recent history. The national average gas price peaked at $5.02 per gallon in June 2022, driven by the initial shock of Russia's invasion of Ukraine and the subsequent Western sanctions that disrupted global crude flows. Prices then fell sharply through late 2022 and 2023 as demand softened and US production ramped up, bottoming near $3.09 per gallon in December 2023.
The 2024 to 2026 period has been characterized by a narrower trading range — roughly $3.10 to $3.80 per gallon nationally — punctuated by periodic spikes tied to OPEC+ decisions, refinery outages, and geopolitical flare-ups. The current level of approximately $3.44 per gallon sits in the middle of that range, meaning there is meaningful upside risk if the Russian diesel situation deteriorates further.
Diesel specifically has been more volatile. The NYMEX heating oil contract — the US diesel benchmark — traded above $4.00 per gallon as recently as spring 2024 during a refinery maintenance crunch. It has since retreated to approximately $2.85 per gallon, but the current inventory draws and geopolitical pressure are pushing it back toward $3.00, a level that historically correlates with broader fuel price increases.
Regional Breakdown
California leads the nation in retail gasoline prices, with the state average near $4.65 per gallon as of mid-September 2026, driven by the state's low-carbon fuel standard, unique CARB-spec gasoline requirements, and limited pipeline connectivity to the rest of the US refining system. Any crude price increase hits California consumers hardest in absolute dollar terms.
The Pacific Northwest — Washington and Oregon — typically tracks California with a slight discount, currently averaging near $4.20 per gallon. Nevada and Arizona, which import California-spec fuel, sit near $3.90 per gallon.
The Midwest (Illinois, Ohio, Michigan, Indiana) currently averages near $3.25 to $3.35 per gallon but is highly sensitive to diesel price moves given the region's agricultural and manufacturing base. A diesel spike heading into harvest season — which runs September through November — would be particularly painful for farmers and truckers, with costs eventually passed to consumers.
The Gulf Coast states (Texas, Louisiana, Mississippi) remain the cheapest markets in the country, averaging $3.05 to $3.15 per gallon, benefiting from proximity to refinery output. The Northeast (New York, Massachusetts, Connecticut) averages $3.50 to $3.65 per gallon and faces the added risk of heating oil demand competing with diesel supply as winter approaches.
What Experts Are Saying
Analysts at Goldman Sachs have previously estimated that each 10 percent reduction in Russian refined product exports adds approximately $3 to $5 per barrel to global diesel benchmarks, with a secondary effect of $1 to $2 per barrel on crude. If Ukraine's strikes have already reduced Russian diesel exports by 15 to 20 percent — and Trump's statement suggests the impact is significant enough to warrant a public diplomatic intervention — that math implies meaningful upside pressure that markets may not have fully priced in.
The EIA, in its most recent Short-Term Energy Outlook, projected that the US regular gasoline retail price would average $3.30 per gallon in the fourth quarter of 2026 — a forecast that was made before this week's developments and may need revision. AAA has noted that distillate inventory tightness is the key variable to watch heading into fall, with a spokesperson indicating that any supply disruption affecting diesel could push gasoline prices 15 to 25 cents per gallon higher than current projections within four to six weeks. GasBuddy's head of petroleum analysis has flagged September as a historically volatile month for fuel prices as summer-blend gasoline transitions to cheaper winter-blend formulations — a transition that typically provides a 5 to 10 cent per gallon tailwind that could be partially or fully offset by the current supply pressures.
What Drivers Should Expect
In the near term — the next one to two weeks — expect gas prices today to drift higher by 5 to 15 cents per gallon nationally if crude oil holds above $82 per barrel and diesel markets remain tight. The transition from summer-blend to winter-blend gasoline, which typically begins in mid-September, should provide some downward price relief, but that seasonal tailwind may be overwhelmed by the supply-side pressures now in play.
The medium-term outlook — October through December — depends heavily on two variables: whether Ukraine continues its strikes on Russian fuel infrastructure, and whether Trump's statement translates into actual policy changes that affect either Ukrainian military operations or the sanctions framework around Russian energy exports. Either outcome introduces uncertainty that markets will price as a risk premium.
For drivers, the actionable advice is clear: do not wait to fill up. If your tank is below half, fill it now before this week's crude price move works its way through the supply chain to retail pumps — a process that typically takes seven to fourteen days. Use GasBuddy or the AAA TripTik app to find the lowest price per gallon within a reasonable driving distance; in most metro areas, there is a 15 to 25 cent per gallon spread between the cheapest and most expensive stations. Wholesale club members at Costco, Sam's Club, or BJ's should prioritize those pumps, where prices typically run 10 to 20 cents below the street average. If you have flexibility in your schedule, Monday and Tuesday mornings historically offer the lowest prices of the week before mid-week demand pushes prices up.
