Futures contracts and daily settlement

A futures contract is a standardized forward traded on an exchange, where a clearinghouse settles gains and losses every day through margin accounts and guarantees performance.

In short

  • Futures have standardized sizes, dates and underlyings set by the exchange, which gives liquidity and removes most default risk.
  • Every day the clearinghouse marks to market: it sets a settlement price and moves that day's gain or loss between the buyers' and sellers' margin accounts.
  • Both sides post initial margin. If the account falls below the maintenance margin, a margin call requires a deposit (variation margin) back up to the initial margin.
  • The total gain or loss equals a forward's, ST−f0(T)S_T - f_0(T) for the buyer; only the timing of the cash flows differs.
  • Exchanges may add price limits or circuit breakers. Positions are usually closed by an offsetting trade before expiry.
