MARGIN & LEVERAGE IN FUTURES

Beginner6 min

Plain English

Futures margin is a performance bond, not a down payment. With $13k initial margin you control $260k of S&P 500 exposure — 20x leverage. Powerful and dangerous in equal measure.

Going deeper

Initial margin is the cash needed to open a position; maintenance margin is the level you must maintain. If equity drops below maintenance, you get a margin call — add cash or close. Day-trade margins are typically 25-50% of overnight margins, encouraging intraday closes. Futures leverage is much higher than equities (Reg-T limits stocks to 2x; futures can be 20x+). Most retail blow-ups come from over-using available leverage, not from being wrong on direction. Use position-sizing rules tied to account size, not exchange minimums.

Examples

ES margin math

ES initial margin ~$13k, contract value ~$260k. That's 20:1 leverage. A 1% market move = $2,600 P&L = 20% on margin. Cuts both ways.

Margin call cascade

Long 5 ES going into a Fed surprise. Market drops 2% in minutes. Equity falls below maintenance, broker auto-liquidates at the worst tick. Pre-set stops would have prevented this.
