WTI Crude Oil: The US Oil Benchmark Explained

Key Takeaways

• WTI crude oil is the US oil benchmark, delivered physically at Cushing, Oklahoma.
• One CME futures contract covers 1,000 barrels, with each 1 cent move worth 10 dollars.
• In April 2020 the expiring WTI contract settled at negative 37.63 dollars per barrel.
• WTI trades at a spread to Brent that reflects US logistics and export capacity.

What WTI Crude Oil Is

WTI stands for West Texas Intermediate, a grade of crude oil prized by refiners because it is "light" (low density) and "sweet" (low sulfur). Those qualities make it relatively easy to refine into gasoline and diesel.

The name also refers to the benchmark futures contract listed by CME Group on the NYMEX exchange. When a trader quotes "the price of oil" in the United States, they usually mean the front-month WTI futures price. The US Energy Information Administration (EIA) publishes an official WTI spot price at Cushing, Oklahoma, alongside the futures market.

The Intuition

Oil is not one uniform product. Grades differ by density and sulfur content, and they sell at different locations with different transport costs. A benchmark solves that problem by giving the market one transparent, heavily traded reference price.

Producers, refiners, airlines, and financial traders all price their deals as a premium or discount to WTI. That shared anchor lets a Texas producer and a Gulf Coast refiner agree terms months ahead without negotiating every grade and location from scratch.

How It Works

The CME WTI contract has fixed specifications so every unit is interchangeable. The contract size is 1,000 US barrels (42,000 gallons). Prices are quoted in US dollars per barrel, and the minimum price move is 1 cent, which equals 10 dollars per contract.

1 WTI contract = 1,000 barrels
tick = $0.01 per barrel = $10.00 per contract

WTI is a physically delivered contract. A trader still holding the front-month contract at expiry must make or take delivery of actual crude at Cushing, Oklahoma. Cushing is a pipeline crossroads with a network of pipelines and storage terminals, which is why it became the delivery point.

Most traders never intend to handle physical barrels. They close or "roll" their position to a later month before expiry. The gap between near and far months is the futures curve, which can be in contango (later months cost more) or backwardation (later months cost less).

Worked Example

Suppose front-month WTI trades at 75.00 dollars per barrel and you buy one contract. Your notional exposure is 1,000 barrels times 75 dollars, or 75,000 dollars, though you post only margin.

If the price rises to 76.50, you have gained 1.50 per barrel. That is 150 ticks at 10 dollars each, or 1,500 dollars on one contract. If it falls to 73.50 instead, you lose 1,500 dollars.

The most extreme illustration came on April 20, 2020. With COVID lockdowns crushing demand and Cushing storage filling to roughly 76 percent of working capacity, holders of the expiring May contract could not find buyers or storage. Per the EIA and CFTC, the contract settled at negative 37.63 dollars per barrel, meaning sellers paid buyers to take the oil. It was the first sub-zero settlement since WTI futures began trading in 1983.

Common Mistakes

1. Confusing the spot price with the futures price. They track each other but are not identical. The EIA spot price reflects physical Cushing deals, while the headline futures price reflects the most active contract month.

2. Ignoring roll cost. Holding oil exposure through an exchange-traded product means rolling contracts. In contango, each roll sells a cheaper expiring month and buys a pricier next month, which erodes returns over time.

3. Assuming WTI equals the global oil price. WTI is a landlocked US benchmark. Brent reflects waterborne crude and is the more common reference for international cargoes. The two can diverge sharply.

4. Forgetting physical delivery risk. Retail traders who hold a physical-delivery contract too close to expiry can be forced to make or take delivery. The 2020 episode showed how dangerous that is when storage runs out.

5. Treating the negative-price event as normal. April 2020 was a rare collision of zero demand, full storage, and expiry mechanics. It does not mean oil routinely trades below zero.

Frequently Asked Questions

What is WTI crude oil in simple terms? WTI crude oil is the main price benchmark for oil in North America, named after a light, low-sulfur grade delivered at Cushing, Oklahoma. It is the number most US traders mean when they quote "the price of oil."

How does WTI crude oil affect investment decisions? WTI sets the reference price for energy producers, refiners, and transport firms, so it feeds directly into their earnings. Investors also use the WTI futures curve to read whether the market expects tighter or looser supply ahead.

What is a real-world example of WTI pricing? On April 20, 2020, the expiring WTI contract settled at negative 37.63 dollars per barrel because storage at Cushing was nearly full and holders could not exit before delivery.

How can investors avoid WTI roll-cost surprises? Check whether the futures curve is in contango before holding a futures-based oil product, and prefer instruments that spread exposure across months or track spot more closely if you want to limit roll drag.

How is WTI different from Brent crude? WTI is a landlocked US benchmark delivered by pipeline at Cushing, while Brent reflects waterborne North Sea crude and prices most international cargoes. The price gap between them shifts with US export and pipeline capacity.
