A contract month is the month-and-year designation of a particular futures contract series. For physically delivered futures, it identifies the month and year in which delivery occurs under the applicable exchange rules; for cash-settled futures, it identifies the month and year in which final settlement occurs. It is commonly synonymous with delivery month. The label identifies a listed maturity, but it does not by itself tell you the contract's last trading day, first notice day, expiration date or exact delivery or settlement date.
A month label, not a single date
Those lifecycle dates are established separately by the rules of the particular contract. Exchanges may list consecutive calendar months, selected quarterly or seasonal maturities, or another product-specific sequence. Each listed contract month is a distinct futures series with its own price, open interest and lifecycle.
NYMEX WTI crude oil shows why the distinction matters. Trading in the expiring contract terminates according to a schedule tied to the twenty-fifth calendar day of the month preceding the delivery month, subject to the rule's business-day and holiday provisions. Physical delivery, by contrast, takes place no earlier than the first calendar day and no later than the last calendar day of the delivery month. A December WTI contract therefore stops regular trading in November even though December is its delivery month.
Contract identity versus position on the curve
Contract Month also differs from Front Month and Deferred Contract. Contract month identifies a specific maturity, such as December 2026. Front month and deferred describe where a listed maturity sits relative to other currently traded maturities. As nearer contracts expire, the same contract month can move from deferred status toward the front of the futures curve without changing its underlying month-year identity.
This distinction matters in market data, calendar spreads, contract rolls and continuous-futures research. A contract-month label should therefore be treated as the identity of the futures series, while its exact trading, notice, delivery and settlement dates should be taken from the applicable contract specifications and exchange rules.
