What Is a Five Against Bond Spread (FAB)?#

A Five Against Bond Spread (FAB) is a futures trading strategy designed to profit from changes in the yield spread between two key Treasury securities:

• 5-year Treasury note futures: These track the price of 5-year U.S. Treasury notes, a medium-term government bond.
• Long-term Treasury bond futures: These track the price of long-term U.S. Treasury bonds with maturities of 15 to 30 years.

The strategy involves taking offsetting positions in these two futures contracts—typically going long one and short the other—to bet on whether the yield spread between the 5-year note and long-term bond will widen or narrow over time.

Key Takeaways#

• Spread Focus: FAB profits from changes in the yield spread between 5-year Treasury notes and long-term Treasury bonds, not just absolute interest rate movements.
• Offsetting Positions: Traders take opposite positions (long/short) in the two futures contracts to hedge against broad market risk.
• Yield Curve Play: FAB is a bet on the shape of the yield curve (e.g., steepening, flattening, or inversion) rather than its overall level.
• Lower Risk Than Outright Positions: By trading a spread, FAB reduces exposure to directional interest rate risk, making it less volatile than trading a single futures contract.

Components of the FAB Strategy#

To execute a FAB, traders need to understand the two underlying futures contracts:

1. 5-Year Treasury Note Futures#

• Underlying Asset: 5-year U.S. Treasury notes with a face value of $100,000 (coupon rates in the deliverable basket vary).
• Price Quotation: Quoted in points and 32nds of a point (e.g., 101-16 = $101,500 for a$100,000 face value contract).
• Exchange: Traded on the CME Group (Chicago Mercantile Exchange) under the ticker symbol FV.

2. Long-Term Treasury Bond Futures#

• Underlying Asset: U.S. Treasury bonds with remaining maturities of 15 to 30 years, a face value of $100,000, and a 6% coupon (deliverable bonds may have coupons between 2% and 15%).
• Price Quotation: Also quoted in points and 32nds of a point (e.g., 130-24 = $130,750 for a$100,000 face value contract).
• Exchange: Traded on the CME Group under the ticker symbol US.

These contracts are highly liquid, making them ideal for spread trading. The spread itself is calculated as the difference between the price of the 5-year note futures and the long-term bond futures (or vice versa, depending on the position).

How Does the FAB Strategy Work?#

The FAB strategy hinges on the yield spread between 5-year notes and long-term bonds. The yield spread is the difference in yields between the two securities (e.g., if 5-year notes yield 3% and long-term bonds yield 4%, the spread is 100 basis points, or 1%).

Traders use FAB to express a view on whether this spread will widen (increase) or narrow (decrease). Here’s how the positions work:

Scenario 1: Expecting the Spread to Widen#

If a trader believes the yield spread will widen (e.g., 5-year yields will rise faster than long-term yields, or long-term yields will fall faster than 5-year yields), they will:

• Go long 5-year note futures (betting their price will rise as yields fall, or fall less than long-term bonds if yields rise).
• Short long-term bond futures (betting their price will fall as yields rise, or rise less than 5-year notes if yields fall).

Scenario 2: Expecting the Spread to Narrow#

If a trader expects the spread to narrow (e.g., long-term yields will rise faster than 5-year yields, or 5-year yields will fall faster than long-term yields), they will:

• Short 5-year note futures (betting their price will fall as yields rise, or rise less than long-term bonds if yields fall).
• Go long long-term bond futures (betting their price will rise as yields fall, or fall less than 5-year notes if yields rise).

The profit or loss depends on how much the spread changes. For example, if the spread widens by 50 basis points, the long 5-year/short long-term position will generate a profit, assuming the price movements align with the yield changes.

Why Trade the FAB Spread?#

FAB offers several advantages over trading individual Treasury futures contracts:

1. Reduced Directional Risk#

Unlike outright long or short positions in a single futures contract, FAB hedges against broad interest rate movements. If interest rates rise or fall across the board, the gains/losses in one leg of the spread may offset losses/gains in the other, reducing overall volatility.

2. Lower Margin Requirements#

Exchanges typically offer lower margin requirements for spread trades (like FAB) than for outright positions. This makes FAB more capital-efficient, allowing traders to allocate less capital while maintaining exposure to yield curve dynamics.

3. Speculating on Yield Curve Shape#

FAB is a tool to express views on the yield curve’s shape (steepening, flattening, or inversion). For example, a steepening curve (long-term yields rising faster than short-term yields) would favor a wide spread position, while a flattening curve would favor a narrow spread position.

4. Hedging for Fixed-Income Portfolios#

Institutional investors (e.g., pension funds, banks) use FAB to hedge against changes in the yield curve that could impact their bond portfolios. By offsetting long cash bond positions with FAB futures, they can mitigate spread risk.

Risks Associated with FAB#

While FAB reduces directional risk, it is not risk-free. Key risks include:

1. Basis Risk#

Basis risk arises when the relationship between the futures contracts and the underlying cash bonds deviates from expectations. For example, if the 5-year note futures price moves out of sync with the actual 5-year cash bond price, the spread may not perform as anticipated.

2. Yield Curve Inversion#

If the yield curve inverts (short-term yields rise above long-term yields), the spread could narrow sharply, leading to losses for traders betting on a widening spread.

3. Liquidity Risk#

While 5-year note and long-term bond futures are generally liquid, during periods of market stress, liquidity may dry up, making it harder to enter or exit positions at desired prices.

4. Transaction Costs#

Trading two futures contracts (instead of one) increases transaction costs, including commissions and bid-ask spreads. These costs can eat into profits, especially for short-term trades.

Real-World Example of FAB#

Let’s walk through a simplified example to see how FAB works in practice:

Setup#

• Current Yield Spread: 5-year notes yield 3.0%, long-term bonds yield 4.0% (spread = 100 basis points).
• Trader’s View: The spread will widen to 150 basis points (5-year yields rise to 3.5%, long-term yields stay at 4.0%).

Trade Execution#

• The trader buys 1 contract of 5-year note futures (FV) at a price of 101-16 ($101,500).
• The trader sells 1 contract of long-term bond futures (US) at a price of 130-24 ($130,750).

Outcome#

• After one month, 5-year yields rise to 3.5% (futures price falls to 100-00, or $100,000).
• Long-term yields remain at 4.0% (futures price stays at 130-24, or $130,750).

Profit/Loss Calculation#

• 5-year note futures (long position): Bought at 101-16 ($101,500), sold at 100-00 ($100,000) → Loss of $1,500.
• Long-term bond futures (short position): Sold at 130-24 ($130,750), bought back at 130-24 ($130,750) → No gain/loss.
• Net Result: The spread widened, but in this case, the 5-year futures price fell due to rising yields. Wait—did we miscalculate?

Ah, right: Bond prices and yields move inversely. If 5-year yields rise, 5-year futures prices fall. Since the trader was long 5-year futures, they lose here. But if the spread widens because long-term yields fall (instead of 5-year yields rising), the outcome changes. Let’s adjust:

Revised Outcome#

• 5-year yields stay at 3.0% (futures price remains 101-16).
• Long-term yields fall to 3.5% (futures price rises to 132-00, or $132,000).

Profit/Loss Now#

• 5-year note futures (long): No gain/loss.
• Long-term bond futures (short): Sold at 130-24 ($130,750), bought back at 132-00 ($132,000) → Loss of $1,250.

Hmm, this still isn’t right. The key is that the spread widens when the difference between yields increases. If 5-year yields rise more than long-term yields, or long-term yields fall more than 5-year yields, the spread widens. Let’s try a scenario where 5-year yields rise by 50 basis points, and long-term yields rise by 25 basis points:

• 5-year yields: 3.0% → 3.5% (futures price falls by $1,500).
• Long-term yields: 4.0% → 4.25% (futures price falls by $750).

Profit/Loss#

• Long 5-year futures: Loss of $1,500.
• Short long-term futures: Gain of $750 (since short positions profit when prices fall).
• Net Loss: $750. Oops—this is a losing trade.

The takeaway: FAB profits depend on the relative movement of the two yields. To profit from a widening spread, the 5-year yield must rise more than the long-term yield (or fall less), leading to the 5-year futures price falling less than the long-term futures price (if short long-term). This requires careful analysis of yield curve dynamics!

How to Implement the FAB Strategy#

To trade FAB effectively, follow these steps:

1. Analyze the Yield Curve#

Study the current yield curve to form a view on whether the spread between 5-year and long-term yields will widen or narrow. Use economic data (e.g., inflation, GDP growth) and Fed policy expectations to inform your view.

2. Select Futures Contracts#

Choose the expiration months for both 5-year note (FV) and long-term bond (US) futures. Most traders use near-month contracts for liquidity, but longer-dated contracts may be used for longer-term views.

3. Determine Position Sizing#

FAB is typically traded with a 1:1 contract ratio (1 FV contract for every 1 US contract), but some traders adjust for duration differences (e.g., long-term bonds have higher duration, so fewer contracts may be needed to balance risk).

4. Execute the Trade#

Place orders to buy/sell the futures contracts through your brokerage. Use limit orders to control entry prices and avoid slippage.

5. Monitor and Manage the Position#

Track the yield spread and adjust the position if the market moves against your view. Set stop-loss orders to limit losses and take-profit orders to lock in gains.

Common Mistakes to Avoid#

• Ignoring Basis Risk: Don’t assume futures prices will perfectly track cash bond prices. Monitor the basis (difference between futures and cash prices) to avoid unexpected losses.
• Overleveraging: Lower margin requirements can tempt traders to take larger positions. Stick to risk management rules to avoid overexposure.
• Misinterpreting Yield Curve Signals: A steepening curve doesn’t always mean the spread will widen—consider the drivers (e.g., Fed hikes vs. growth expectations).
• Neglecting Liquidity: Avoid illiquid expiration months, as wide bid-ask spreads can erode profits.

Conclusion#

The Five Against Bond Spread (FAB) is a powerful strategy for traders looking to profit from yield curve movements in Treasury markets. By trading the spread between 5-year note and long-term bond futures, FAB reduces directional risk and offers exposure to the shape of the yield curve. However, success requires a deep understanding of yield curve dynamics, careful risk management, and monitoring of basis and liquidity risks.

Whether you’re a speculator betting on curve steepening or a portfolio manager hedging spread risk, FAB can be a valuable addition to your trading strategy—provided you do your homework.
