CME Energy Futures Specs Guide: CL, NG & Brent Contract Details Explained

Energy futures on CME - Crude Oil (CL), Natural Gas (NG), and Brent Crude Oil (BZ) - are vital tools for traders managing price risks or speculating on energy markets. Here's what you need to know:

• Crude Oil (CL): Each contract represents 1,000 barrels of WTI crude. Prices move in $0.01 increments, worth $10 per tick. Contracts settle physically in Cushing, Oklahoma. Trading is highly liquid, with over 1 million contracts traded daily.
• Natural Gas (NG): Each contract equals 10,000 MMBtu, with a $0.001 tick size valued at $10. Physical delivery occurs at Henry Hub, Louisiana. NG futures rank as the third-largest commodity futures by volume, trading 400,000 contracts daily.
• Brent Crude Oil (BZ): Representing 1,000 barrels per contract, Brent futures settle financially, avoiding physical delivery. Prices also move in $0.01 increments, valued at $10 per tick. Brent is the global oil benchmark, reflecting international supply and demand.

Key details like tick values, margin requirements, and trading hours are critical for informed trading. For example, CL and NG settle physically, while Brent is cash-settled. Trading hours run nearly 24/5, with a short daily maintenance break.

Quick Comparison:

Understanding these contracts helps traders calculate profits, manage risks, and navigate expiration schedules effectively. Whether you're trading WTI, Henry Hub NG, or Brent, knowing the specifics is crucial for success.

Crude Oil (CL) Futures Contract Specifications

Contract Size, Tick Size, and Pricing

A single CL futures contract represents 1,000 barrels of light sweet crude oil, which translates to about 42,000 gallons. Prices for these contracts are quoted in U.S. dollars and cents per barrel.

The smallest price movement, or tick size, is $0.01 per barrel, equating to a $10.00 change per contract. For example, a one-cent price move impacts the contract value by $10. A 50-cent price change, such as from $75.00 to $75.50 per barrel, would result in a $500 shift per contract. This tick value plays a key role in calculating potential profits, losses, and stop-loss levels.

Specification	Details
Ticker Symbol	CL
Contract Size	1,000 barrels
Price Quotation	USD and cents per barrel
Minimum Tick	$0.01 per barrel ($10.00/contract)
Settlement Method	Physical Delivery
Delivery Location	Cushing, Oklahoma

Next, let’s dive into how the listing cycle and expiration details shape the trading life of these contracts.

Listing Cycle and Expiration Details

CL futures are available for trading across the current year, the next 10 calendar years, and two additional contract months. This extended availability gives traders the flexibility to hedge against long-term price risks or to implement spread strategies over multiple years.

Trading for a contract ends three business days before the 25th of the month preceding the contract month. The active month, which is the most liquid, typically shifts two business days before the expiration of the spot month.

Since CL futures are settled through physical delivery, traders must either close or roll their positions to avoid taking delivery of 1,000 barrels of crude oil in Cushing, Oklahoma. Delivery can be managed through interfacility transfer, in-line transfer, or in-tank transfer of title.

Now, let’s examine the margin requirements and trading hours, which define the financial and operational framework for trading CL futures.

Margin Requirements and Trading Hours

As of March 19, 2026, the initial margin for trading a CL contract is set at $9,830, while the maintenance margin is $8,937. However, many brokers offer lower day trading margins, often around $2,000. These reduced margins require traders to close their positions before the daily break at 4:00 p.m. CT. Otherwise, the account must meet the higher overnight margin requirement.

With contracts valued at approximately $75,000 (based on a $75/barrel price), crude oil futures offer significant leverage. A $1.00 price move in the underlying oil translates to a $1,000 change per contract, highlighting the potential for both profit and risk. Exchange fees for trading CL contracts are $1.52 per contract.

CME Globex trading hours for CL run Sunday through Friday, 5:00 p.m. – 4:00 p.m. CT, with a 60-minute maintenance break starting at 4:00 p.m. CT each day. Traders should pay close attention on Wednesdays at 10:30 a.m. ET, when the EIA Weekly Petroleum Status Report is released. This report often triggers significant price volatility, which can impact margins and stop-loss strategies.

Natural Gas (NG) Futures Contract Specifications

Contract Size, Tick Size, and Pricing

Each Henry Hub Natural Gas (NG) futures contract represents 10,000 MMBtu. Prices are quoted in U.S. dollars and cents per MMBtu. The smallest price movement, or tick size, is $0.001 per MMBtu, which equals $10.00 per contract. For example, if the price moves from $2.940 to $2.941 per MMBtu, the resulting profit or loss would be $10.

The notional value of a single contract is about $29,400 (based on a price of $2.94 per MMBtu as of March 2, 2026). This highlights the leverage NG futures provide. A price change of $0.10 per MMBtu - say, from $2.94 to $3.04 - translates to a $1,000 gain or loss per contract, showcasing both the efficiency and the risks involved.

Specification	Details
Ticker Symbol	NG
Contract Size	10,000 MMBtu
Price Quotation	U.S. dollars and cents per MMBtu
Minimum Tick	$0.001 per MMBtu ($10.00/contract)
Settlement Method	Physical Delivery
Delivery Location	Henry Hub, Louisiana
Exchange Fees	$1.62 per contract

Henry Hub Natural Gas ranks as the third-largest physical commodity futures contract by trading volume. With about 400,000 contracts traded daily and an open interest of 1.7 million contracts, it’s a major player in the energy markets. For those seeking smaller exposure, the Micro Henry Hub Natural Gas (MNG) contract is available at one-tenth the size (1,000 MMBtu).

Listing Cycle and Expiration Details

NG futures are offered in monthly contracts, covering the current year and the next 12 years. This extended listing cycle is designed for traders managing long-term price risks or creating calendar spreads.

Trading for a specific contract ends three business days before the first day of the delivery month[3,16]. Since these contracts involve physical delivery at Henry Hub, Louisiana[3,15], traders who don’t plan to take delivery must either close or roll their positions before expiration. This underscores Henry Hub's role as the primary benchmark for U.S. natural gas pricing.

To simplify rolling positions, CME provides Trading-at-Settlement (TAS) spreads (NGT) for the first 12 consecutive monthly contracts. These allow trades to be executed at the day’s settlement price, easing the transition between contract months. Additionally, traders can use calendar spread options - ranging from 1 to 12 months - for more advanced strategies.

Thursdays are particularly important for NG traders, as the EIA storage reports released on this day often cause sharp price fluctuations. In the U.S., electric power generation accounts for about 40% of natural gas consumption, while industrial use makes up around 32%. This makes seasonal demand shifts a critical factor in price movements.

Margin Requirements and Trading Hours

Margin requirements depend on the contract month, with higher margins typically applied in winter and early spring due to increased volatility. For example:

• The March 2026 contract requires $3,519 for long positions and $3,348 for short positions.
• The June 2026 contract has lower margins, requiring $2,555 for long positions and $2,478 for short positions.

Some brokers offer day trading margins as low as $1,000, but holding positions overnight usually requires around $5,691. This setup highlights the leverage in NG contracts, where a relatively small margin controls a large notional value.

Trading hours on CME Globex are Sunday to Friday, 5:00 p.m. to 4:00 p.m. CT, with a 60-minute maintenance break starting at 4:00 p.m. CT[16,17,15]. Traders should stay alert for sudden price swings, as winter cold snaps can spike heating demand, while summer heatwaves may drive up electricity use for air conditioning.

These details are crucial for understanding the dynamics of trading NG futures.

Brent Crude Oil Futures Contract Specifications

Contract Size, Tick Size, and Pricing

Each Brent Crude Oil futures contract (BZ or BB) represents 1,000 barrels, with prices quoted in U.S. dollars and cents per barrel. The smallest price movement, or tick, is $0.01 per barrel, translating to a tick value of $10 per contract. A $1.00 price change in Brent crude impacts the contract's value by $1,000.

These futures are financially settled, meaning no physical delivery takes place. Instead, positions are settled using the ICE Brent Index. Traders face an exchange fee of about $0.77 per contract (often reduced when using a low intraday margin futures broker) and overnight margins around $4,192.

Specification	Details
Ticker Symbol	BZ (or BB)
Contract Size	1,000 barrels
Price Quotation	U.S. dollars and cents per barrel
Minimum Tick	$0.01 per barrel ($10 per contract)
Settlement Method	Financial (Cash Settled)
Exchange Fees	Approximately $0.77 per contract

Trading hours on CME Globex run Sunday to Friday, 6:00 p.m. to 5:00 p.m. ET, with a one-hour maintenance break starting at 5:00 p.m. ET.

Now, let’s explore how the listing cycle and settlement rules influence trading execution.

Listing Cycle, Expiration, and Settlement

Brent futures are listed as monthly contracts spanning the current year and the next seven calendar years. For most months, trading ends on the second last business day in London and the U.S., two months before the contract month. For example, a May contract expires in March. However, February contracts follow a special rule, with trading ending on the third last business day of the month.

"Trading in the February contract month terminates on the 3rd last London and U.S. business day of the month, 2 months prior to the contract month. Trading in all other contract months terminates on the 2nd last London and U.S. business day of the month, 2 months prior to the contract month."
– CME Group

The final settlement price is determined by the ICE Brent Crude Oil 1st nearby contract on the second-to-last trading day, ensuring a cash-settled process that avoids the complexities of physical delivery.

The Brent benchmark has evolved over time, now drawing from a basket of crude grades including Forties, Oseberg, Ekofisk, Troll, and, as of 2023, WTI Midland from the U.S. This addition has formally tied Brent prices to U.S. production.

"The grades that underpin the Brent benchmark have changed over time... to include Forties, Oseberg, Ekofisk and Troll. To add further supply... WTI Midland, produced in the U.S., was added to the Brent basket in 2023, formally linking the price of Brent with WTI."
– CME Group

This evolution has influenced pricing dynamics and increased the benchmark's sensitivity to global and regional market changes, making it a critical factor for international trading strategies.

Brent vs. WTI (CL) Contracts Comparison

Brent and WTI serve distinct market purposes, reflecting their unique roles in global and domestic oil markets. Brent is widely regarded as the global benchmark, capturing seaborne crude fundamentals and geopolitical risks. On the other hand, WTI is the U.S. benchmark, tied to landlocked crude stored in Cushing, Oklahoma, and more directly influenced by U.S. production and inventory levels.

The settlement process is another key difference. WTI contracts involve physical delivery at Cushing, requiring traders to close or roll over positions before expiration to avoid delivery. Brent contracts, however, are cash-settled, making them more straightforward for traders focused on price movements.

Feature	Brent Crude (BZ)	WTI Crude (CL)
Benchmark Type	Global/International	U.S./Domestic
Source	Seaborne crude	U.S. landlocked crude
Settlement	Financial (Cash Settled)	Physical Delivery
Contract Size	1,000 barrels	1,000 barrels
Tick Size	$0.01 per barrel ($10 per contract)	$0.01 per barrel ($10 per contract)
Listing Cycle	Current year + 7 years	Current year + 9–10 years (typically)
Expiration	2nd last business day, 2 months prior	25th calendar day of the month preceding delivery
Price Sensitivity	Global supply & geopolitical risk	U.S. inventories & production

While both contracts share the same size and tick value, Brent's earlier expiration requires careful planning for rolling positions or crafting trading strategies.

Trading Energy Futures: Margins, Hours, and Execution

CL, NG, and Brent Specifications Comparison

Here's a quick breakdown of the key specifications for Crude Oil (CL), Natural Gas (NG), and Brent Crude (BZ) futures:

Specification	Crude Oil (CL)	Natural Gas (NG)	Brent Crude (BZ)
Contract Size	1,000 barrels	10,000 MMBtu	1,000 barrels
Tick Size / Value	0.01 / $10.00	0.001 / $10.00	0.01 / $10.00
Settlement Method	Physical (Cushing, OK)	Physical (Henry Hub)	Financial (Cash)
Trading Hours (ET)	6:00 p.m. – 5:00 p.m.	6:00 p.m. – 5:00 p.m.	6:00 p.m. – 5:00 p.m.
Execution Methods	Globex, TAS, TAM, ClearPort	Globex, TAS, ClearPort	Globex, TAS, ClearPort

All three contracts operate on CME Globex from Sunday to Friday, with trading hours running from 6:00 p.m. to 5:00 p.m. ET. However, there's a daily 60-minute maintenance break starting at 5:00 p.m. ET, during which liquidity tends to drop significantly.

One of the most noticeable differences among these contracts is the settlement method. While CL and NG require physical delivery (Cushing, OK, and Henry Hub, respectively), Brent's cash-settlement structure simplifies trading for those focused on speculation rather than delivery logistics.

Practical Trading Scenarios and Examples

Understanding these specifications allows traders to tailor their strategies using various execution tools. For instance, advanced order types like Trading at Settlement (TAS) can help traders execute orders at a differential to the daily settlement price, making it a handy tool for managing price fluctuations. Similarly, Trading at Marker (TAM) for Crude Oil enables execution based on specific marker prices instead of the settlement price, offering another layer of flexibility.

Let’s consider a scenario: A trader is preparing for the U.S. Energy Information Administration (EIA) weekly petroleum status report, released every Wednesday at 10:30 a.m. ET. These reports often cause sharp price swings in CL and NG contracts. A trader expecting an inventory build might use TAS orders to secure a favorable settlement price while sidestepping the wild price movements during the announcement.

For those looking to manage smaller positions, micro contracts like Micro WTI Crude Oil (MCL) and Micro Henry Hub Natural Gas (MNG) are excellent options. These contracts are just 1/10th the size of standard contracts and are financially settled, eliminating the need to worry about physical delivery. With tick values reduced to $1.00 instead of $10.00, they allow for more precise position sizing, making them ideal for traders managing limited capital exposure.

Lastly, keeping track of expiration dates is critical. For example, CL contracts expire three business days before the 25th of the month preceding delivery, while Brent contracts terminate on the second-to-last business day two months before the contract month. Missing these deadlines could lead to forced liquidations or, worse, unintended physical deliveries. Always double-check expiration schedules to avoid unnecessary complications.

FAQs

How do I roll CL or NG before delivery?

Rolling Crude Oil (CL) or Natural Gas (NG) futures before delivery is a straightforward process that helps you avoid physical delivery while keeping your market exposure intact. Here's how it works:

To roll your position, you’ll need to close your current position in the near-term contract and open a new position in a later-dated contract. This ensures you stay in the market without taking on the obligation of physical delivery.

Key Steps to Follow:

• Identify the relevant contracts: Look at the expiration dates for the current and next month's contracts.
• Close your current position: Exit the near-term contract before it expires.
• Open a new position: Enter the next month's contract to maintain your exposure.
• Check with your broker: Confirm deadlines and margin requirements to ensure a smooth transition.

By staying on top of these details, you can effectively manage your futures positions without any interruptions or surprises.

Why does Brent expire so early?

Brent contracts expire early because trading halts at the close of the designated settlement period on the last business day of the second month preceding the contract month. This timeline can shift slightly for holidays like Christmas or New Year’s, ensuring settlements are handled smoothly and in line with established market practices.

What’s the real risk with day-trading margins?

Day-trading margins come with a significant risk: the leverage effect. While leverage can amplify potential profits, it also magnifies losses. Even minor price fluctuations can lead to losses that surpass your initial investment. Because day-trading margins are lower than overnight margins, traders are more vulnerable to sudden market swings. This heightened exposure makes disciplined risk management absolutely essential. Without it, unexpected market movements can quickly drain your trading capital, trigger margin calls, or force the closure of positions.
