RBOB Gasoline: The US Gasoline Futures Benchmark

Key Takeaways

• RBOB gasoline futures price wholesale US gasoline before ethanol is blended in.
• One CME contract is 42,000 gallons (1,000 barrels), with each tick worth 4.20 dollars.
• The gasoline crack spread measures a refiner's margin over crude oil cost.
• Gasoline prices follow a strong seasonal pattern, peaking around summer driving demand.

What RBOB Gasoline Futures Are

RBOB is gasoline blendstock ready to receive a 10 percent ethanol addition at the truck rack. Refiners make the blendstock; the finished motor fuel sold at the pump is RBOB plus ethanol. Trading the blendstock rather than finished gasoline keeps the contract standardized.

The CME RBOB contract is the benchmark for the New York Harbor barge market, the main physical hub for gasoline on the US East Coast. The EIA publishes spot prices for conventional and reformulated gasoline that track the same physical market.

The Intuition

A refiner buys crude oil and sells products, mainly gasoline and diesel. Its profit depends on the gap between what it pays for crude and what it gets for fuel, not on the absolute price of either.

RBOB futures let refiners, blenders, and large fuel buyers lock in gasoline prices ahead of time. A wholesaler supplying gas stations can hedge a winter purchase commitment by buying RBOB futures, removing the risk that prices spike before the fuel is delivered.

How It Works

The RBOB contract size is 42,000 US gallons, equal to 1,000 barrels. Prices are quoted in US dollars and cents per gallon. The minimum price move is 0.0001 dollars (one hundredth of a cent) per gallon, which equals 4.20 dollars per contract.

1 RBOB contract = 42,000 gallons = 1,000 barrels
tick = $0.0001 per gallon = $4.20 per contract

The contract is physically delivered in New York Harbor, with a 2 percent loading tolerance above or below the contract size. Most financial traders close or roll positions before delivery.

A central concept is the crack spread, the difference between the product price and the crude price. The "RBOB crack" converts gasoline (priced per gallon) and crude (priced per barrel) into common units. Since there are 42 gallons in a barrel, the crack is calculated as the gasoline price times 42 minus the crude price.

Worked Example

Suppose WTI crude trades at 75.00 dollars per barrel and RBOB trades at 2.40 dollars per gallon. To compute the gasoline crack, convert the gasoline price to a barrel basis:

RBOB crack = (2.40 x 42) - 75.00
           = 100.80 - 75.00
           = $25.80 per barrel

A 25.80-dollar crack means a refiner earns that gross margin per barrel converting crude into gasoline, before operating costs. A refiner worried about the margin collapsing can lock it in by selling RBOB futures and buying crude futures together, a position called a short crack.

Seasonality matters too. Gasoline demand and prices generally rise into the summer driving season, helped by a switch to more expensive summer-grade fuel. A trader holding RBOB through that window is exposed to both the price move and the seasonal pattern.

Common Mistakes

1. Confusing RBOB with pump gasoline. RBOB is blendstock before ethanol. Finished retail gasoline includes ethanol plus taxes and distribution costs, so the futures price is well below what you pay at the pump.

2. Mixing up the units in a crack spread. Gasoline trades per gallon, crude per barrel. Forgetting the 42-gallon conversion produces a meaningless crack number.

3. Ignoring the summer-winter spec change. Summer-grade gasoline must meet stricter volatility rules and costs more to make. The seasonal switch creates predictable shifts in RBOB pricing that catch out unprepared traders.

4. Treating RBOB as a pure bet on crude. Gasoline can rally or fall independently of crude when refinery outages, demand shifts, or inventory swings move the crack. The product price is not just crude plus a constant.

5. Holding a physical-delivery contract too long. Like all CME energy futures, RBOB delivers physically. Retail traders must roll or close before expiry to avoid delivery obligations in New York Harbor.

Frequently Asked Questions

What are RBOB gasoline futures in simple terms? RBOB gasoline futures are exchange-traded contracts on wholesale US gasoline blendstock before ethanol is added. They are the main benchmark for the price of gasoline at the wholesale level.

How do RBOB gasoline futures affect investment decisions? They drive refiner margins through the crack spread, so they feed directly into energy-company earnings. Wholesalers and fleet operators also use them to hedge fuel costs ahead of purchase.

What is a real-world example of RBOB pricing? If RBOB trades at 2.40 dollars per gallon and WTI at 75 dollars per barrel, the gasoline crack is about 25.80 dollars per barrel, the refiner's gross margin on that fuel.

How can investors use RBOB futures effectively? Refiners hedge by selling RBOB and buying crude to lock in a crack spread, while buyers can hedge purchase commitments by going long RBOB. Watching the seasonal summer demand pattern helps time exposure.

How is RBOB gasoline different from ULSD or heating oil? RBOB is gasoline blendstock for cars, while ULSD and heating oil are middle distillates used in trucks, furnaces, and machinery. They are separate refined products with their own crack spreads and demand cycles.
