The Five Against Bond Spread (FAB) strategy is a futures trading approach designed to capitalize on the yield differential between distinct maturity Treasury bonds. This involves executing opposing positions in futures contracts for five-year Treasury notes and extended-term (15 to 30 years) Treasury bonds.

Deciphering the Five Against Bond Spread (FAB) Phenomenon

The intricate landscape of a Five Against Bond Spread materializes through the execution of futures contracts. This involves either acquiring a futures contract for five-year Treasury notes while divesting one for long-term Treasury bonds or vice versa. Traders engaging in this spread aim to capitalize on interest rate fluctuations, endeavoring to exploit the pricing differentials in Treasuries.

Various Treasury securities, spanning 2-year, 5-year, 10-year, and 30-year durations, serve as the canvas for futures contracts. Unlike options that grant the right to buy or sell, futures impose an obligation on the holder. Facilitated by the Chicago Board of Trade, these contracts align with cycles in March, June, September, and December. A FAB requires futures contracts with a face value of $100,000, priced in points per $1,000. Trading occurs in tick sizes as minimal as 1/32 of a point, translating to $31.25 for 30-year bonds and half of 1/32 of a point, equivalent to $15.625 for 10-year notes.

While certain Treasury futures strategies aim to hedge against interest rate risks, the FAB strategy distinguishes itself by actively seeking gains from rate and yield oscillations. Positioned within the array of spread trading strategies in the Treasury market, FAB, along with its counterparts, leverages the belief that disparities in spreads, as manifested in futures contract prices across the Treasury yield curve, will eventually normalize. This strategic play focuses on the more enduring shifts in yields, deviating from the swift price dynamics characteristic of equity markets.

Factors Affecting Five Against Bond Spread

The dynamics of the Five Against Bond Spread are intricately entwined with bond yields, influenced primarily by prevailing interest rates. Short-term interest rates, heavily influenced by the US Federal Reserve, revolve around its federal funds rate, which has wide-ranging implications. The Fed's rate adjustments notably impact the 2-year and 5-year Treasury yields. Meanwhile, the vitality of the US economy and the trajectory of inflation play pivotal roles in determining long-term bond rates. Robust economic growth and an inflation rate surpassing 2% tend to drive down long bond yields. Investors delving into spread strategies must meticulously factor in these financial and technical considerations, among others, to navigate this complex terrain.


The Five Against Bond Spread strategy navigates futures trading with a focus on yield differentials in Treasury bonds. This complex approach involves opposing positions in futures contracts for five-year Treasury notes and long-term bonds. Traders must consider economic indicators, interest rate fluctuations, and technical details like tick sizes and face values in FAB contracts. Positioned within spread trading strategies, FAB distinguishes itself by actively seeking gains from enduring shifts in yields, providing a strategic alternative in the intricate financial landscape.
