Gasoline

A gasoline — a light refined petroleum fraction distilled from crude oil — is the primary transportation fuel for personal automobiles in the developed world and the largest volume refined product globally. Gasoline prices directly affect consumer purchasing power, inflation expectations, and political popularity of governments, making them among the most closely watched commodity prices.

The fuel of personal mobility

Gasoline is the lifeblood of personal vehicle transportation in developed economies. Over 1 billion cars globally rely on gasoline (alongside diesel and electric alternatives). When gasoline prices spike, consumers immediately feel the pain at the pump, reducing discretionary spending and driving political anger.

A $1 increase in gas prices costs a typical American household an extra $500–1,000 per year; this translates to consumer spending cuts in other categories. Gasoline price spikes therefore create negative wealth effects and inflation concerns that ripple through the economy.

Production and refining constraints

Gasoline production is limited by refinery capacity. A typical refinery processes 100,000–500,000 barrels per day of crude oil, producing a fixed mix of products (gasoline, diesel, heating oil, jet fuel) based on crude type and refinery configuration.

Refineries operate 24/7 at high capacity utilization (85–95%) because refining is a low-margin, high-volume business. When a major refinery shuts for maintenance (every 2–3 years), that capacity is lost for weeks, tightening supply and raising prices.

US refining capacity has actually declined slightly over past decades due to permanent closures; no new refineries have been built in the US since 1977. This constraint limits the US’s ability to meet demand spikes and has made refineries strategically important.

Crude oil input and crack spreads

Gasoline prices track crude oil prices closely because crude is roughly 60% of refining costs. When crude rises, gasoline rises. The difference between crude input cost and gasoline output price is called the “crack spread” and reflects refinery profitability.

A wide crack spread (gasoline much more expensive than crude) signals healthy refinery profitability; refineries expand utilization and investment. A narrow or negative crack spread signals refinery losses; refineries reduce output and cut capital investment.

The crack spread is actively traded as a financial instrument, with traders betting on refinery profitability.

Seasonal patterns and driving seasons

Gasoline demand is weakly seasonal, with slightly higher consumption in summer (more driving, vacations) and slightly lower in winter. However, the seasonal pattern is small compared to heating oil.

More important is multi-year growth from emerging-market vehicle sales. China’s vehicle fleet has grown explosively, driving global gasoline demand growth of 1–2% annually.

Refining margins and profitability

Refineries operate on thin margins (1–3% of sales). In high-crude-price environments, these margins compress, making refining uneconomical. In low-crude-price environments, margins expand if refineries can sell products without price cuts.

This margin dynamics explains why refinery utilization rates vary: when margins are poor, refineries reduce output or temporarily shut down; when margins are strong, refineries run flat-out.

RBOB futures and retail gasoline

The primary gasoline futures contract on NYMEX is RBOB (Reformulated Blendstock for Oxygenate Blending), which trades at lower volumes than crude oil or heating oil but with sufficient liquidity for hedging.

RBOB prices correlate to retail gasoline prices but differ due to distribution costs, taxes (~50¢/gallon US average), and regional variation. California gasoline prices, for example, are often $0.50–1.00 per gallon higher than national average due to stricter environmental specifications.

Retail price spreads

The spread between wholesale RBOB futures prices and retail pump prices reflects:

• Distributor margins: 5–10¢/gallon
• Retailer margins: 10–15¢/gallon (often promotional, so actual margins are thin)
• State and federal taxes: 40–60¢/gallon
• Transportation and storage: 5–10¢/gallon

Retail pump prices are therefore much more “sticky” than wholesale prices, moving more slowly to track wholesale shifts due to consumer psychology and promotional pricing.

Demand destruction and elasticity

Gasoline demand is relatively inelastic in the short run; drivers cannot abandon cars. However, at very high prices ($5–6 per gallon), demand destruction emerges. Higher prices also incentivize vehicle electrification and public transit usage.

A prolonged period of $5+ gasoline (like 2008 and 2022) reduces gasoline consumption 5–10% within months, which is significant given the thin refining margins.

Political sensitivity

Gasoline prices are more politically sensitive than any other commodity because they affect billions of consumers directly and daily. High gasoline prices have toppled governments and driven political change.

This political sensitivity means governments sometimes intervene via:

• Fuel subsidies: Capping retail pump prices below market levels (common in developing countries).
• Strategic Petroleum Reserve releases: Increasing supply during price spikes.
• Environmental regulations changes: Temporarily loosening fuel specs during shortages.
• Tax suspensions: Temporarily eliminating fuel taxes.

These interventions can suppress prices temporarily but create market distortions.
