Rising diesel prices in the United States are no longer merely a fluctuation in the energy market. They signal the transfer of geopolitical pressure and disruptions in the energy supply chain into the heart of Americans’ economic lives. The average price of diesel in the United States has reached a record $6 per gallon, while in California, the gap with prices a year ago has widened to an unprecedented level. In San Francisco, the average price has surpassed $8 and is approaching $9. Reuters has described the surge as part of a worsening global diesel supply squeeze driven by geopolitical crises.
Under these circumstances, the question of “$10 diesel” is no longer merely a media talking point. Of course, $10 is not yet an established market price in the United States. But when the market moves from one record to another, refining capacity is under pressure, and the global market for middle distillates faces shortages, it is not entirely far-fetched that some local US markets could reach that level. The main issue is not crude oil; the bottleneck lies in refined products, refining capacity, inventories, and logistics.
This distinction is strategically important. The modern US economy is deeply dependent on diesel. Trucks, agricultural machinery, trains, construction equipment, parts of maritime transportation, and much industrial machinery run on diesel. Any sustained increase in its price therefore quickly moves from the fuel pump to freight rates, production costs, food prices, and ultimately household spending. In other words, diesel is one of the main channels through which a geopolitical crisis is converted into domestic inflation.
This is where the significance of Iran’s new strategy in response to the US maritime blockade becomes clearer. Mohsen Rezaei, Secretary of Iran’s Supreme National Security Council, has spoken of establishing a “no-go zone” outside the Strait of Hormuz. In strategic terms, this approach has been described as “besieging the besieger” — shifting part of the cost of the blockade from Iran’s economy to the economic and maritime networks of the opposing side and other stakeholders.
Within this framework, Hormuz is no longer merely a geographic passage for oil tankers; it becomes a lever for influencing the global energy chain. Reports also indicate that the current crisis has affected the market for refined products more than just the crude oil market, with pressure on diesel and other middle distillate fuels emerging as one of the most significant vulnerabilities of the global economy.
If this trend continues, its effects in the United States could unfold in a chain reaction: more expensive diesel means more expensive transportation; more expensive transportation means more expensive food; more expensive food means greater inflationary pressure; and higher inflation puts further pressure on interest rates and financing costs. Under such circumstances, the issue is not simply how many extra dollars a truck driver pays per gallon; it is the rising cost base across a large part of the economy.
Agriculture is among the first sectors to be affected by such a chain reaction. Tractors, combines, trucks carrying agricultural products, and logistics equipment all depend on fuel. A diesel shock can therefore begin on the farm and ultimately reach the grocery shelf. This is where an energy crisis becomes a cost-of-living crisis.
From the perspective of war, this development carries added significance. The United States may be able to withstand a period of pressure militarily, but the resilience of a major power is not measured solely by the number of its warships and aircraft. Its economic and social capacity to absorb the costs of war is also part of its national power.
The strategy of “besieging the besieger” focuses precisely on this point: increasing the cost of war for the opposing side without necessarily confining the pressure to direct military confrontation. The longer the energy crisis continues, the more its costs will spread from financial and energy markets to transportation, agriculture, the food industry, and households.
For this reason, the $10 figure should be taken seriously as a warning indicator. The strategic question now is not whether the average US diesel price will reach $10 tomorrow. The question is how far the US economy can withstand the cascading rise in costs if the refining crisis and supply disruptions persist.
San Francisco, now approaching $9, may be more than just a point on the map. It could offer a picture of the path that a prolonged energy crisis may chart for America’s economic and military resilience.
