Roll Yield

The return generated as a bond's price converges toward its par value as it approaches maturity, or from rolling futures contracts.

Roll yield is the return generated in futures or fixed-income markets as a contract or bond naturally approaches its expiration or maturity date. In futures markets, it occurs when an investor rolls a short-term contract that is nearing expiration into a longer-term contract. If the market is in backwardation (where futures prices are lower than the spot price), rolling a long position generates a positive yield because the investor is buying cheaper contracts to replace expiring ones. Conversely, in contango (where futures prices are higher than the spot price), the roll yield is negative. In fixed-income investing, roll yield is often referred to as roll-down return. It represents the price appreciation a bond experiences as its remaining maturity shortens, assuming the yield curve remains stable. Because bond prices generally converge toward their par value as they approach maturity, a bond purchased at a discount will naturally rise in price over time, independent of broader interest rate movements. Investors monitor roll yield to optimize the timing of their contract rolls and to enhance total returns in fixed-income portfolios. A common pitfall is assuming that historical roll yields will persist; if a futures market shifts from backwardation to contango, or if the yield curve shifts unexpectedly, a previously profitable roll strategy can quickly turn into a drag on performance.

An investor holds a long futures contract expiring this month at a spot price of $50. The next month's contract is trading in backwardation at $48. To maintain exposure, the investor sells the expiring contract for $50 and buys the next month's contract for $48, capturing a positive roll yield of $2 per contract ($50 - $48 = $2).
