Roll Yield: Definition, Positive & Negative Scenarios

Comprehensive guide to understanding Roll Yield, its positive and negative scenarios, and its application in the futures market.

Definition

Roll yield refers to the return generated when an investor rolls a short-term futures contract into a longer-term one, specifically in the context of the futures market being in backwardation or contango.

Backwardation and Contango

• Backwardation: A market condition where the spot price is higher than the futures price.
• Contango: A market condition where the futures price is higher than the spot price.

Positive Roll Yield

When is Roll Yield Positive?

Roll yield is positive when the futures market is in backwardation. In this scenario, investors can benefit from higher spot prices relative to futures prices when they roll over their contracts.

Example of Positive Roll Yield

If an investor holds a futures contract that is approaching expiry and the futures market is in backwardation, they will sell the expiring contract at a higher spot price and buy a new, longer-term futures contract at a lower price. The difference in these prices generates a positive roll yield.

$$ \text{Positive Roll Yield} = S(t) - F(t) $$

Where \( S(t) \) is the spot price and \( F(t) \) is the futures price.

Negative Roll Yield

When is Roll Yield Negative?

Roll yield becomes negative when the futures market is in contango. In this situation, investors face lower spot prices relative to futures prices when rolling over their contracts, leading to a loss.

Example of Negative Roll Yield

If the market is in contango, the investor will sell their expiring contract at a lower spot price and buy a new, longer-term futures contract at a higher price. This price difference results in a negative roll yield.

$$ \text{Negative Roll Yield} = F(t) - S(t) $$
