Leverage

Leverage is the feature that pulls speculators into futures. It is also the feature that makes futures dangerous. Both of those come from the same fact: a trader puts up only a small deposit to control a large position. Get this idea right and the rest of the unit follows.

What Leverage Is

Start with the deposit, because everything about leverage flows from how small it is.

• Leverage is the ability to control a large contract value while committing only a small amount of capital.
• That committed capital is the performance bond (also called futures margin): a good-faith deposit posted to guarantee the trader will meet their obligations as the price moves.
• The performance bond is only a small fraction of the contract's total notional value (the full dollar value of the commodity the contract represents), so the trader controls far more market exposure than the cash they put up.
• This is the defining draw of futures for a speculator: a small deposit buys exposure to a large position, so even a modest price move can return a large percentage on the cash committed.

Think of it this way: leverage is a long lever. Push down a little on your end, the small deposit, and the far end, the full contract value, moves a lot. The longer the lever, the more the far end swings for the same push. Futures hand the speculator a very long lever, which is exactly why a small move in the commodity turns into a large move in the account.

• The percentage return is measured against the performance bond, not the full contract value. That small denominator is why futures swings feel enormous. A price move that is trivial against the notional value can be huge against the deposit.

Leverage Magnifies Both Directions

Leverage does not favor the trader. It amplifies whatever the price does, up or down, by the same factor.

• Because the deposit is small relative to the position, a small percentage move in the futures price produces a large percentage gain or loss on the deposited funds.
• Leverage is symmetric: it magnifies profits and losses to exactly the same degree. There is no version of leverage that boosts gains without boosting losses.
• A speculator's loss is not capped at the performance bond. An adverse move can wipe out the deposit and still require additional funds to cover the position.

A round illustration makes the symmetry concrete. Suppose a performance bond of $5,000 lets a trader control a contract with a notional value of $100,000. The deposit is 5% of the position, so the trader is leveraged 20 to 1.

• If the contract value rises 5% (to $105,000), the $5,000 gain equals a 100% return on the $5,000 deposit.
• If the contract value falls 5% (to $95,000), the $5,000 loss is a 100% loss of the deposit.
• If the contract value falls 10%, the $10,000 loss is twice the deposit: the trader loses the $5,000 and owes another $5,000.

Think of it this way: the same 5% move swings the account by 100% in whichever direction the price went. Leverage is not a discount on risk; it is a multiplier on it. The trader who loves what leverage does to a winner has to accept the identical effect on a loser.

Exam Tip: Gotchas

• Leverage cuts both ways. A common trap frames leverage as only an amplifier of gains. The correct view is symmetric: the same small deposit that magnifies a winner magnifies a loser just as much.
• A futures loss is not limited to the deposit. Because leverage can push losses past the performance bond, the speculator can be required to add funds. "Leverage magnifies risk" is always a true statement for futures.

Performance Bond Is Not a Down Payment

The word "margin" tempts students to picture buying stock on credit. In futures, the deposit works nothing like that, and the exam tests the difference.

• The performance bond is not a partial payment toward owning the commodity. The speculator is not buying the commodity; there is no ownership and no financing involved.
• It is not a cost of the trade either. (An option premium is a cost, money spent that does not come back. A performance bond is a deposit that does.)
• It is a security deposit that ensures the financial integrity of the trade. It is returned, adjusted for gains and losses, once the position is closed by offset (an equal and opposite trade that cancels the original).

Futures margin and securities margin share a word but not a meaning:

Think of it this way: securities margin is a loan; you borrow part of the purchase price and pay interest until you settle up. A futures performance bond is a security deposit, closer to what a tenant hands a landlord: you have not bought anything, you owe no interest, and you get the deposit back (plus or minus how the trade went) when you walk away.

Exam Tip: Gotchas

• Do not confuse the futures performance bond with securities margin. Securities margin is a loan-financed partial payment, so the buyer owes interest. A futures performance bond is a good-faith deposit posted by both the long and the short, with no loan, no ownership, and no interest.
• "Performance bond" and "margin" mean the same thing in futures, and neither is a down payment. The deposit guarantees performance on the contract; it does not buy the commodity.
