Futures trading offers leveraged access to a wide range of markets, but before placing your first trade, you need to understand futures margin requirements. Unlike stock margin, which involves borrowing money from a broker, futures margin is a good-faith deposit that ensures you can cover potential losses. Knowing the difference between initial margin vs. maintenance margin for futures can help you manage capital more effectively and avoid unexpected liquidations.

Key Takeaways

• Futures margin is a performance bond, not a loan; it represents a small percentage of a contract's total notional value.

• There are three main types: initial margin, maintenance margin, and intraday (day trading) margin.

• Exchanges like CME Group set baseline requirements; brokers may add their own overlays.

• Margin requirements change with market volatility, news events, and structural contract updates.

• If your account falls below the maintenance margin level, you may receive a margin call or face position liquidation.

Part 1. What Are Futures Margin Requirements?

A futures margin requirement is the minimum amount of money a trader must deposit in their account to open and hold a futures position. It is not a down payment toward ownership of an asset. Instead, it functions as collateral, sometimes called a "performance bond," that protects all parties involved in the contract.

Futures margin requirements are calculated based on the potential risk of price movement in a given contract. The CME Group uses a risk model called SPAN (Standard Portfolio Analysis of Risk), which evaluates 16 different price scenarios to determine the maximum likely loss over a one-day period. The margin is then set to cover 99% of those scenarios.

Because futures use leverage, the margin requirement is typically a small fraction of the contract's notional value. According to CME Group, futures margin generally represents 3% to 12% of the notional value of the contract. This is significantly lower than stock margin, which under Federal Reserve Regulation T allows borrowing up to 50% of the purchase price.

It is important to note that futures are leveraged products. While leverage can amplify potential gains, it can also amplify losses. Traders should be aware that it is possible to lose more than the initial margin deposited to open a futures position.

Part 2. Types of Futures Margin Requirements Explained

Understanding the different types of futures margin is essential before placing any trade. Each type serves a distinct purpose and applies at different stages of holding a futures position.

2.1 Initial Margin

Initial margin is the amount of equity required in your account to open a new futures position. This is the starting threshold, whether you plan to hold the position overnight or through a future expiration date.

On Webull, initial margin applies when you open a position with the intention of holding it through the end of intraday trading hours, or when opening a position outside of those hours. The initial margin requirement on Webull is typically between 3% and 12% of the futures contract's notional value, depending on the contract and current market conditions.

2.2 Maintenance Margin

Maintenance margin is the minimum equity level you must maintain in your account once a position is open. It is always lower than the initial margin requirement.

On Webull, if your account equity drops below the maintenance margin level, you will be asked to bring the account back up to the initial margin requirement. If this is not done promptly, your position may be liquidated.

As an illustration: if the initial margin for one ES contract is $13,200 and the maintenance margin is approximately $10,000 to $11,000, a move of roughly 80 points against your position (a $4,000 loss on a single contract) could bring your equity close to the margin call threshold.

2.3 Intraday (Day Trading) Margin

Intraday margin, also called day trading margin, is the reduced margin requirement available for positions opened and closed within designated intraday trading hours, with no intention of holding through the session close.

On Webull, intraday margin is the lowest margin requirement available for eligible contracts. It generally applies between 9:00 AM ET and 4:15 PM ET. Intraday margin increases leverage, which can increase risk and may not be suitable for all investors.

Brokers set their own intraday margin rates, and these can be significantly lower than exchange-level initial margin. However, if a position is not closed before the intraday session ends, the account must meet the full initial margin requirement. Failure to do so can result in automatic position liquidation at market prices.

Part 3. How Futures Margin Requirements Are Set and Why They Change

Margin requirements are not fixed. They are dynamic and reflect the current state of the market. Knowing who sets them and what drives changes can help traders plan better and avoid surprises.

3.1 Who Sets Margin Requirements

Two entities determine the margin requirements a trader must meet: the exchange and the broker.

The exchange establishes the baseline initial and maintenance margin levels. For contracts like the ES, NQ, and their micro equivalents, that is CME Group. According to CME Group, margins are evaluated at the end of each trading day.

The broker can increase margin requirements above exchange levels based on their own risk assessment. Brokers may also offer reduced intraday margin rates to attract active retail traders. This broker-level flexibility means requirements can vary across platforms.

3.2 Why Margins Change

Margin requirements are designed to reflect real-time risk. Several factors commonly drive changes:

• Market volatility: When price swings become more extreme, exchanges raise margins to ensure traders can cover potential losses. During the March 2020 onset of the COVID-19 pandemic, the CME raised margins on the E-mini S&P 500 six times between March 2 and March 23, 2020. The initial margin for the E-mini S&P 500 rose from approximately $6,600 to $12,000 during that period.

• News and geopolitical events: Elections, armed conflict, and unexpected macroeconomic announcements can prompt temporary margin increases as a risk safeguard.

• Liquidity: Reduced liquidity, such as during non-US market hours, can lead brokers to apply higher intraday margins.

• Contract structure changes: Updates to tick size, lot size, or the exchange's risk model can also affect margin levels.

Part 4. Futures Margin vs. Stock Margin: Key Differences

Traders coming from equities often find futures margin works very differently. The table below outlines the core distinctions.

One of the most significant differences is that futures are subject to daily mark-to-market settlement. Gains and losses are credited or debited to your account at the end of each trading day, even if the position remains open. This means unrealized losses become very real every day, unlike stocks where unrealized losses are not settled until a position is closed.

5.4 What Happens If You Fall Below Margin on Webull

If your account equity drops below the maintenance margin requirement due to adverse price movements, Webull will require you to deposit sufficient funds to bring the account back up to the initial margin level. If you do not meet this requirement, your position may be liquidated.

Webull also enforces last holding date policies to prevent physical delivery. Physical delivery is not supported on Webull, so positions in physically deliverable contracts must be closed or managed before the last holding date. If no action is taken by 11 AM ET on the last holding date, Webull may close the position on your behalf.

Buying power on Webull is calculated as: Cash + Margin Requirements minus open orders. It is not the same as your cash balance.

Futures margin requirements define how much capital you need to open and hold a position, and they shift with market conditions. Understanding the difference between initial, maintenance, and intraday margin is foundational to managing risk effectively. Webull provides futures trading access for eligible US residents with transparent margin structures, multiple order types, and dedicated support. Always review current margin rates before placing a trade, as requirements can change.
