Prompt month refers to the nearest delivery month for futures contracts or the most immediate delivery period for physical commodities. Prompt month contracts typically exhibit the highest liquidity and trading volumes while being most sensitive to current supply-demand conditions. These contracts serve as the primary vehicles for price discovery and immediate hedging needs.

Prompt month pricing often differs from deferred months due to immediate supply-demand imbalances, storage costs, and convenience yields. As contracts approach expiration, prompt month prices converge toward spot prices through arbitrage mechanisms. Understanding prompt month dynamics helps assess immediate market conditions and near-term price pressures.

Real-world example: January crude oil futures become the prompt month in December, showing increased volatility and trading volume as traders focus on immediate delivery obligations and current market fundamentals affecting near-term supply and demand.
