General Theory

The whole unit on one sheet: why futures markets were built, and how a futures contract differs from a security.

Which One-Liners Win Points?

• Standardization makes a futures contract tradable. Every contract for one commodity and month is identical, so any long offsets any short. That interchangeability is called fungibility.
• A forward contract is private and custom; it can only be unwound by renegotiating with the original counterparty.
• The clearinghouse becomes the buyer to every seller and the seller to every buyer. Default risk moves off the individual trader onto the clearinghouse.
• A futures contract is an obligation, not ownership. It gives no dividends, no interest, and no voting rights.
• The obligation binds both sides. The long must take delivery, the short must make delivery, unless each offsets first.
• Selling stock transfers title; offsetting a futures position cancels the obligation. No commodity changes hands on an offset.

Who Wants What in the Market?

• Hedgers deal in the physical commodity and use futures to offset their price risk.
• Speculators have no interest in the commodity; they take on price risk hoping to profit from a price move, and their willingness to bear it gives hedgers liquidity.
• The spot price is the cash price for immediate delivery. Price risk is the chance the spot price moves against a party before the real transaction happens.

Which Gotchas Trip Students Up?

• Margin in futures is a performance bond, not a loan or partial payment. It is good-faith collateral. Stock margin is borrowed money, a different meaning.
• A long futures position is not ownership of the commodity. Treating it like owned stock is the classic trap.
• Ownership of the underlying transfers only on physical delivery, which most positions never reach because they offset first.
• "Development of the futures market" is a concept question, not a history-date question. The exam wants the chain of reasoning, not founding years.

What Is the Memory Aid for Futures Versus Securities?

A security is something you store: you own it and it can pay you. A futures contract is something you must fulfill: both sides owe performance unless they offset.

One-Breath Recap

Futures markets exist so producers and users can lock in a price and transfer price risk to speculators who want the price move. Private forwards had two flaws: custom terms no third party could take on, and dependence on one counterparty's creditworthiness. Standardizing contract size, grade, delivery month, and location made contracts fungible so any long offsets any short, and inserting a clearinghouse that becomes buyer to every seller and seller to every buyer removed default risk, backed by margin as a performance bond. A futures contract is an obligation binding both the long and the short, not ownership, so it pays no dividends or interest, and a position is exited by an offsetting trade through the clearinghouse rather than by transferring title.
