Understanding Futures Margin
Margin in futures trading is the earnest money deposited in cash (or sometimes collateral like U.S. T-bills or bank guarantees) required by exchanges to open and maintain positions. It serves as a performance guarantee, covering potential liabilities from adverse price movements.
Key Points:
- Initial Margin: Minimum funds needed to open a position.
- Maintenance Margin: Minimum balance to keep a position open; if breached, a margin call is triggered.
- Margin requirements adjust based on market volatility and are set by exchanges (brokers cannot set lower than exchange minimums).
- Unlike stock margins, futures margins are fixed dollar amounts (e.g., $1,320 per cattle contract).

Initial Margin vs. Maintenance Margin
Initial Margin
The upfront capital required to enter a futures trade. Excess funds beyond this can be withdrawn or used for new positions.
Example:
- Initial margin: $1,000
- Account balance: $1,500 → $500 is excess margin.
Maintenance Margin
The minimum balance to avoid liquidation. If the account falls below this, traders must top up to the initial margin level.
Example:
- Maintenance margin: $500
- If equity drops to $400, deposit $600 to restore $1,000.
Permissible Margin Deposits
Traders can use:
- Cash: 100% of deposit value.
- Securities: Discounted via "haircut" (e.g., bonds at 80% value, stocks at 75%).
Note: Funds in securities and commodity accounts cannot be co-mingled without a signed transfer agreement.
Hedge vs. Speculative Margins
| Type | Margin Requirement | Risk Level |
|-----------------|------------------------|----------------|
| Hedgers | Lower | Reduced (price stability) |
| Speculators | Higher | Higher (volatility exposure) |
Why? Hedgers (e.g., farmers) offset price risks, making their positions less volatile.
Spread Margin
Spread positions (offsetting contracts) incur lower margins due to reduced risk.
Example:
- Long crude oil + short natural gas = Lower margin vs. standalone positions.
