Back Month
1. Definition
Back Months (or Far Months / Deferred Months) refer to any futures contracts that expire after the Front Month.
2. Characteristics
- Lower Liquidity: Trading volume is generally thinner compared to the front month. This results in wider Bid-Ask spreads and higher slippage risk.
- Forward Curve: The prices of back months plot the "Forward Curve," indicating the market's expectation of future prices.
- Cost of Carry: In normal markets (Contango), back month prices are higher than the front month because they include the costs of storage, insurance, and financing over the longer period.
3. Usage
- Calendar Spreads: Traders speculate on the widening or narrowing of the price gap between the Front Month and Back Month.
- Long-term Hedging: Producers and consumers use these contracts to lock in prices for delivery far into the future (e.g., an airline buying fuel for next year).
