CL: Crude Oil Futures

Introduction

Among commodity futures, none is more famous or more actively traded than crude oil — ticker CL. Oil is the lifeblood of the global economy, and its price ripples through everything from petrol pumps to airline profits to inflation itself. CL is where that price is discovered, traded and hedged, around the clock, by producers, refiners, airlines, funds and speculators worldwide.

But CL comes with a feature that sets it apart from the equity-index futures: it is physically settled. That single fact makes it a more demanding — and occasionally dramatic — contract to trade, as the extraordinary events of April 2020 proved.

Quick Definition

CL is the futures contract on WTI crude oil (West Texas Intermediate), a benchmark grade of US crude. One contract represents 1,000 barrels and is physically settled — it obliges delivery of actual oil at expiry.

What CL Tracks

CL tracks West Texas Intermediate (WTI), a specific grade of light, sweet US crude oil delivered at a hub in Cushing, Oklahoma. WTI is one of the world's two primary oil benchmarks (the other being Brent), and CL is the most liquid way to trade it. When headlines report "oil prices", they're usually quoting WTI or Brent — and CL is the WTI market in action.

Key Specifications

• Underlying: WTI crude oil
• Contract size: 1,000 barrels
• Tick size / value: $0.01 per barrel = $10.00 per contract
• Settlement: physical delivery (at Cushing, Oklahoma)
• Expiries: monthly
• Trading hours: nearly 24 hours a day, five days a week
• Smaller version: the Micro (MCL) is one-tenth the size (100 barrels, $1 tick)

With a $1 move in oil worth $1,000 on a full contract, and oil routinely swinging dollars in a day, CL is a large, volatile instrument — the Micro (MCL) is where most individuals should start.

Why Physical Settlement Matters

CL's physical settlement is its defining risk. Unlike cash-settled index futures, the standard CL contract obliges the delivery of real barrels of oil at Cushing. For the producers and refiners the market serves, that's the whole point. For a speculator, it's a trap to avoid: you must close or roll your position before the delivery process begins, or risk being obligated to take (or make) delivery of 1,000 barrels you have no way to handle.

This is why understanding Futures Settlement matters so much more for CL than for ES. The delivery notice and expiry dates are hard deadlines, not suggestions.

Contango And Backwardation

Because oil can be stored, its futures curve has a shape worth knowing:

• Contango — longer-dated contracts priced higher than near-term ones. This often reflects the cost of storing oil over time, and typically appears when near-term supply is ample.
• Backwardation — longer-dated contracts priced lower than near-term ones, often signalling tight near-term supply, where buyers pay a premium for oil now.

The curve's shape affects anyone rolling contracts over time: rolling in persistent contango means repeatedly selling cheaper expiring contracts and buying dearer later ones — a drag on returns that has quietly eroded many long-term oil positions and oil-tracking funds.

What Drives Oil

CL is a geopolitical and macroeconomic instrument. Its price responds to:

• Supply decisions — especially from OPEC and major producers adjusting output.
• Geopolitics — conflicts, sanctions and instability in producing regions.
• Global demand — the health of the world economy, which lifts or dents oil consumption.
• The US dollar — oil is priced in dollars, so dollar strength or weakness feeds into the price.
• Inventories — weekly US stockpile data can move the market sharply.

This mix makes CL one of the most headline-sensitive, volatile futures a trader can touch.

The April 2020 Lesson

In April 2020, the WTI futures price did something once thought impossible: it went negative, briefly trading around minus $37 a barrel. Collapsing pandemic demand had filled storage to bursting, and holders of the expiring physically-settled contract found there was literally nowhere to put the oil they'd be obligated to receive. To escape delivery, they had to pay others to take the contracts off their hands — pushing the price below zero.

It was a once-in-a-lifetime event, but a permanent lesson: with physical settlement, holding a commodity contract into expiry without the means to handle delivery is genuinely dangerous. The mechanics of settlement are not academic — they can, in extremis, cost you more than the commodity's entire value.

Common Misconceptions

"Oil futures are cash-settled like index futures." The standard CL is physically settled. This is the single most important thing to know before trading it.

"Prices can't go below zero." April 2020 proved otherwise for physically-settled contracts under storage stress. Negative prices are rare but real.

"Rolling a long oil position is free." In contango, rolling repeatedly can steadily erode returns — a real cost that surprises many long-term holders and oil ETF investors.

Real-World Application

An airline, dreading a rise in fuel costs, buys CL futures to lock in today's oil price — a textbook hedge. If oil rises, its higher fuel bill is offset by gains on the futures; if oil falls, it pays more for the hedge but enjoys cheaper fuel. Either way, it has swapped uncertainty for a known cost, exactly as the futures market intends.

A speculator, by contrast, might trade the Micro (MCL) to bet on an OPEC supply cut driving prices up — but must diarise the expiry and delivery dates religiously, closing or rolling well before them so they never approach the delivery obligation. Forget, and the April 2020 nightmare is the extreme reminder of what physical settlement can mean. Oil offers some of the biggest, most news-driven moves in all of futures — thrilling to trade, but only for those who respect its physical-delivery mechanics and its volatility.

Key Takeaways

• CL is the future on WTI crude oil; one contract = 1,000 barrels, tick value $10, and it is physically settled.
• Physical settlement means speculators must close or roll before expiry to avoid a delivery obligation.
• Contango (upward curve) and backwardation (downward curve) describe the futures curve and affect the cost of rolling positions over time.
• Oil is driven by OPEC, geopolitics, global demand, the dollar and inventories — highly volatile and headline-sensitive.
• April 2020's negative prices are a lasting lesson in the real dangers of physical settlement at expiry.
• The Micro (MCL) is the sensible way to size this large, volatile contract.
