Oil Executives Project 6-Month Lag Before Pump Prices Normalize Post-War

A single barrel of Brent crude has dropped from a peak of $110 to near $95, yet drivers at the pump face a $4.12 average for gasoline and a diesel price that remains $2.50 above year-ago levels. This price gap persists despite the war in Iran that disrupted global supply lines.

The conflict has forced a rerouting of global energy flows. Before the hostilities began, approximately one-fifth of the world's oil transited the Strait of Hormuz. The throttling of this waterway pushed crude prices from $70 in late February to sustained levels above $100 for several months. AAA data confirms that while diesel hit a record high of $6.52 in September, it has only marginally decreased since, leaving consumers paying a premium for refined products.

Market participants expect a rapid initial reaction to any formal peace agreement. Jaime Brito, executive director of refining and oil markets for Dow Jones Energy, stated that traders would likely see crude prices drop by $15 to $20 per barrel within two to three days of an announcement. This immediate price adjustment would require formal statements from both the U.S. and Iran confirming the reopening of the strait and the withdrawal of military forces.

The transmission of lower crude prices to the consumer pump will be slower due to logistical constraints. Ships currently taking longer, alternative routes to avoid the strait must return to their original paths, a process that could create traffic bottlenecks. Jorge León, head of geopolitical analysis at Rystad Energy, noted that this physical movement of barrels adds time to the market adjustment. Once the crude reaches refineries, it must be processed and distributed before retail prices reflect the change.

Analysts disagree on the specific timeline for price normalization. Brito estimates that in the most optimistic scenario, gasoline and diesel prices could return to prewar levels within three months of a ceasefire. León suggests a longer horizon, predicting it would take six months for crude to stabilize at prewar levels, followed by an additional one to two months for refined fuel prices to catch up. Both experts acknowledge that supply chain hiccups could extend this recovery period to a full year.

Political changes in Washington may not accelerate this timeline. Although Democrats now hold a majority in Congress, they cannot be sworn in until January. Until then, the President retains full executive authority over military strikes, sanctions, and licenses. Claudio Galimberti, chief economist at Rystad Energy, wrote that a unified Democratic Congress could make escalation more costly by attaching conditions to war spending, but legislative power is limited compared to executive discretion. President Trump acknowledged voter dissatisfaction with fuel costs on election night, and Vice President JD Vance attributed the Republican losses to the war.

External factors continue to complicate the recovery. The war in Ukraine remains a variable, as Russian refineries supply a large portion of the global diesel market. If Ukraine continues to target these facilities, diesel prices may fall more slowly than gasoline. Additionally, U.S. refineries are operating above 90% capacity, leaving little room for emergency maintenance during a period of increased oil availability. Rising freight and insurance costs for shipping around the strait have also increased the baseline cost of moving oil, potentially keeping Brent crude elevated even after hostilities cease.

Brito warned that if the administration views the period before the new Congress convenes in January as a window to complete military objectives, new attacks could occur before the end of the year. He concluded that for prices to return to normal, the market needs to see a definitive end to the conflict, not just a pause in fighting.
