Settlement Price

An exchange or clearing framework specifies a common settlement reference for consistent financial calculation. CME explains that daily settlement prices are used to mark positions to market and determine profits or losses, and its money-calculation material describes futures settlement variation being banked in cash each day.

A daily valuation can therefore create a real funding requirement before the position closes. For an existing long futures position, a higher settlement normally produces a positive daily price difference and a lower settlement produces a negative one, with contract quantity, value factor and product-specific rounding converting the movement into the relevant cash amount.

Daily variation on a position carried overnight is based on today's settlement relative to the previous settlement, not repeatedly on the original trade price, so the successive cash movements capture the path across the days the position remains open. A new trade has a different starting reference, because CME's explanation separates the move from that trade's execution price to the day's settlement from the move on positions already open at the start of the day, and mixing these bases can double-count or omit a day's result.

Daily settlement is different from final settlement, which can determine the cash payoff or other contract outcome at expiry and need not share the same observation time, averaging method or publication process. Contract specifications determine the method, and a product can use eligible market observations or another stated process within its settlement framework.

The last displayed trade is not an adequate substitute when the rules specify a different official reference. Time matters because different contracts can observe different windows, so a market move after the relevant window may appear in a screen quote without changing that day's established reference.

Read the actual timing and status rather than assume every product settles at one universal close. The reference is also not a promise of an executable price, since a trader trying to exit still faces current bids, offers, available size and transaction costs, and an official settlement can be appropriate for clearing without being available for a fresh trade.

Daily settlement variation also differs from initial margin, because variation reflects the relevant marked price changes while initial margin concerns the collateral required to support the position. Rounding and value factors can matter, as CME describes different calculation methods for normal futures and certain notional products, so a broad price-difference formula gives intuition but exact reconciliation requires the relevant product's stated convention.

Some related products have additional cash adjustments, so reconcile the official clearing statement rather than assume every contract's cash flow follows one simplified example. For a non-finance manager using derivatives, identify the exact contract and reference source in the cash forecast.

Separate trade price, previous settlement, daily settlement and final settlement. That distinction helps explain why a hedge can require cash today even when its overall commercial purpose remains sound.
