Factors Influencing the Price Differential

Multiple elements affect the price difference between fuel and gasoline. Supply chain logistics, production expenses, and seasonal demand fluctuations play vital roles. For instance, during peak agricultural seasons, fuel demand surges for farming equipment, driving up prices. Moreover, regulatory changes, such as the introduction of Ultra-Low Sulfur Diesel (ULSD) requirements, add to production costs, further impacting diesel pricing. Economic conditions, including crude oil prices and currency fluctuations, also significantly affect the pricing dynamics of these fuels.

To illustrate, the Ukraine war’s impact on global commodity prices is a prime example. Following the invasion in February 2022, US gasoline prices saw a sharp rise due to economic sanctions on Russia, with the producer price index (PPI) for gasoline jumping 85% above the previous year. Oil prices, which averaged $78 per barrel in December, were under pressure from weak global economic activity, record US output, and steady production from Russia. Despite these pressures, the geopolitical uncertainties and disruptions in supply chains led to volatile pricing.

Furthermore, the introduction of ULSD has significantly raised production expenses for the fuel. This regulatory change mandates lower sulfur content in fuel, requiring more complex refining processes. ‘The transition to ULSD, although advantageous for the environment, has led to increased expenses related to fuel production.’.

In a broader context, ExxonMobil’s plans and operational changes illustrate how companies adapt to these dynamics. ‘Their medium-term business plans take into account structural savings and the effect of government mandates on sustainable production levels.’.
