What You'll Learn
Supply and demand
The law of supply and demand is a fundamental concept in economics that describes the market dynamics between buyers and sellers. It asserts that when demand for a product rises, prices increase as well, and when demand falls, prices drop. Conversely, when supply increases, prices tend to decrease, and when supply decreases, prices tend to rise.
Demand for diesel fuel has been relatively high, especially in regions like Europe, China, India, and the United States. Diesel fuel is a major transportation fuel, and its demand often aligns with economic trends. The transition to less polluting, lower-sulfur diesel fuels has also impacted production and distribution costs, making diesel more expensive to produce.
On the supply side, there are several factors contributing to the high diesel prices. Firstly, there is a general decline in refining capacity and low inventories, which can be attributed to reduced investments in upstream infrastructure. Additionally, supply chain disruptions and geopolitical tensions, such as the conflict between Russia and the West, have further constrained the supply of diesel fuel.
The isolation of the West Coast liquid fuels market, particularly in California, also contributes to supply issues. This market is relatively isolated compared to other U.S. markets due to a lack of interconnecting pipelines and river systems. As a result, when a refinery outage occurs, it can be costly to transport supplies from outside the region, leading to higher prices.
Furthermore, local market conditions, transportation costs, and taxes influence diesel prices. Transportation costs tend to increase with the distance from the source of supply, affecting areas farther from the Gulf Coast, a major production hub. Local market factors, such as competition, traffic patterns, and the nature of retail outlets, can also impact diesel prices.

Geopolitical factors
Several geopolitical factors influence the high price of diesel fuel. One significant factor is the conflict between Russia and Ukraine, which has led to a reduction in the supply of diesel and heavy oils to the West. The Biden administration's decision to stop importing Russian oil has further contributed to the supply issues. As a result, the price of diesel has been affected, with big exporters like China, Russia, and Saudi Arabia selling less diesel and crude oil.
Additionally, the transition to less polluting and lower-sulfur diesel fuels has also impacted diesel prices. The cost of producing diesel increased due to the need for additional capital and operating costs to meet the new ultra-low-sulfur diesel (ULSD) standards. Refineries had to invest billions of dollars in equipment to remove sulfur, and this put upward pressure on diesel prices. The ULSD change also affected the price differential between gasoline and diesel, with diesel becoming more expensive.
Moreover, the high price of diesel fuel is influenced by the global demand for diesel, especially in regions like Europe, China, India, and the United States. The use of diesel in transportation, industrial machinery, and agriculture contributes to its demand and impact on inflation. Diesel inventories can decline rapidly due to unexpected supply declines or lagging imports, leading to higher prices as wholesalers and marketers bid higher for available supplies.
The geopolitical struggle between Russia and the West has also contributed to the apparent supply shortfall, affecting the price of diesel fuel. Sanctions and low stockpiles resulting from these tensions have further driven up prices. Overall, these geopolitical factors have significantly influenced the high price of diesel fuel globally.

Production costs
The production costs of diesel fuel are influenced by various factors, including crude oil prices, refining processes, and distribution costs. Crude oil prices are determined by worldwide demand and supply, with economic conditions influencing the demand for petroleum products derived from crude oil. Diesel fuel, being a major transportation fuel, follows these economic trends in terms of demand.
In the United States, the transition to less polluting, lower-sulfur diesel fuels has impacted production and distribution costs. The implementation of ultra-low-sulfur diesel (ULSD) standards required refineries to invest significant capital in new equipment to remove sulfur. This, in turn, increased the cost of producing diesel due to higher capital and operating expenses. Additionally, the demand for lower-sulfur ("sweet") crudes increased, further impacting production costs.
Refineries in the US typically produce 11-12 gallons of diesel per barrel, compared to 19 gallons of gasoline. The lower yield of diesel contributes to higher production costs. Moreover, the isolation of the West Coast liquid fuels market, particularly in California, affects production costs due to the higher cost of transporting supplies from outside the region when refinery outages occur.
Distribution and transportation costs also play a role in the overall production costs of diesel fuel. Transportation costs tend to increase with the distance between the retail location and the source of supply. Regions farther from the Gulf Coast, a major source of US diesel fuel production, often experience higher diesel prices due to transportation costs. Additionally, local market conditions, such as the location and ownership of retail outlets, can impact prices. High-volume truck stops, for example, often sell diesel fuel at lower prices than smaller-volume service stations.
Overall, the production costs of diesel fuel are influenced by a combination of factors, including crude oil prices, refining requirements and investments, yield per barrel, and transportation and distribution costs. These factors collectively contribute to the overall price of diesel fuel for consumers.

Transportation costs
The isolation of the West Coast liquid fuels market, which includes California, further exacerbates the issue. Unlike other regions in the United States that are interconnected by pipelines and river systems, the West Coast market relies primarily on in-region refinery production. When a refinery outage occurs, it becomes costly to transport supplies from outside the region, driving up prices.
Taxes also play a significant role in the transportation costs of diesel fuel. As of January 1, 2024, California's state taxes on retail, on-highway diesel fuel were significantly higher than the national average, at 96.32 cents per gallon compared to an average of 34.74 cents per gallon across all 50 states. These taxes contribute to the overall transportation costs and, ultimately, the retail price of diesel fuel in these regions.
The transition to less polluting, lower-sulfur diesel fuels has also impacted transportation costs. The federal excise tax for on-highway diesel fuel is 24.3 cents per gallon, which is higher than the tax on gasoline. Additionally, refineries had to invest in new equipment to meet the ultra-low-sulfur diesel (ULSD) standards, increasing production costs. The shift to ULSD also affected the price differential between gasoline and diesel, with diesel becoming more expensive due to the higher costs of producing lower-sulfur fuels.
The demand for diesel fuel, particularly in the transportation and logistics industries, contributes to the high transportation costs. Diesel fuel is a major transportation fuel, and its demand often aligns with economic trends. The recent geopolitical tensions between Russia and the West have also influenced transportation fuel prices. As key exporters like China, Russia, and Saudi Arabia sell less diesel and crude oil, the apparent supply shortfall drives up prices globally.

Local taxes
The federal excise tax for on-highway diesel fuel is also higher than that for gasoline, contributing to the overall higher cost of diesel fuel. The federal excise tax for diesel is 24.3 cents per gallon, 6 cents more than the tax on gasoline. While the tax rate on diesel fuel has not changed since 1993, the transition to less polluting, lower-sulfur diesel fuels has increased production and distribution costs, which are reflected in the retail price.
In addition to federal taxes, local and state taxes can also impact diesel fuel prices. For example, truck stops located within 200 miles of each other in Florida can have significantly different diesel prices due to variations in local taxes and market conditions. The cost of doing business, including overhead, local real estate costs, and taxes, can vary depending on the location of the dealer, influencing the retail price of diesel fuel.
The impact of local taxes on diesel prices is also influenced by the location and ownership of retail outlets. Refiners own and operate some retail outlets, while others are independent businesses that purchase diesel fuel on the wholesale market. Independent retailers may face higher costs in procuring diesel fuel, especially if they are located far from production sources, which can result in higher prices for consumers.
While local taxes play a significant role in diesel pricing, it is important to consider other factors as well. Supply and demand, production costs, and market conditions all contribute to the overall price of diesel fuel. However, local taxes remain a key component in the complex equation that determines the final price consumers pay at the pump.
