Yield Curve Trading Strategies
Yield Curve Trading Strategies
The yield curve is not just a recession indicator; it is a source of trading profit. Sophisticated investors use curve positions to capitalize on expected changes in yield spreads and durations.
Key takeaways
- Yield curve traders profit by taking positions in different maturity segments, betting on curve steepening, flattening, or twists
- A curve steepener bets the long end outperforms the short end; a flattener bets the opposite
- Butterfly trades exploit three-legged curve positions to profit from curvature changes
- Carry trades reward holding longer bonds if the curve remains steep or stable
- These strategies require active management and risk-taking; they are not passive buy-and-hold strategies
The Basics: Relative Value Positioning
The fundamental principle of yield curve trading is relative value. A trader does not ask "is the 10-year expensive or cheap in absolute terms?" Instead, a trader asks "should the 10-year yield more than the 5-year, given the current macro environment?"
When a trader believes the long end is too cheap relative to the short end (i.e., the curve is too flat), the trader can buy the long end and short the short end. If the curve steepens (long yields fall or short yields rise, or both), the long position profits while the short position loses less, netting a gain.
This "relative value" mindset allows curve traders to profit without making directional bets on the absolute level of yields. A steepener can profit even if all yields rise, as long as the long end rises less (or falls more) than the short end.
Steepener Trades
A curve steepener is the most common yield curve trade. The bet is that the spread between longer and shorter maturities will increase.
The structure: Typically, a steepener is constructed by:
- Long (buying) a longer-maturity bond, like the 10-year.
- Short (shorting, or equivalently, selling a future or purchasing a receiver swaption) a shorter-maturity bond, like the 2-year.
The trader profits if:
- The 10-year yield falls while the 2-year stays flat (the curve steepens from a flattened state).
- The 2-year yield rises while the 10-year stays flat (the curve steepens from an inverted state).
- Both move, but the long end falls or rises less than the short end.
When is it attractive?: Steepeners are attractive when:
- The curve is inverted or very flat, and the trader expects it to normalize (revert to a steep, positive slope).
- The Fed is expected to cut rates sharply in the near term (pushing short yields down) while longer yields hold (creating steepness).
- The economy is weakening, which historically steepens the curve as investors flee to long-term safety.
Example from 2022: In early October 2022, the 2-10 spread was near -100 bps (deeply inverted). A trader betting the Fed's tightening campaign was ending might have bought the 10-year and shorted the 2-year, expecting the curve to steepen from -100 to 0 (or even positive). Such a position would have profited through November and December 2022 as the curve did steepen.
Risk: The main risk in a steepener is that all yields rise together (the Fed continues tightening, growth surprises to the upside), in which case both the long and short positions lose, with the long position losing more due to greater duration.
Flattener Trades
A curve flattener is the opposite bet: that the spread between longer and shorter maturities will decrease.
The structure: A flattener is constructed by:
- Short (shorting) a longer-maturity bond, like the 10-year.
- Long (buying) a shorter-maturity bond, like the 2-year.
The trader profits if:
- The 10-year yield rises while the 2-year stays flat (the curve flattens).
- The 2-year yield falls while the 10-year stays flat (the curve flattens).
- The curve goes from steep to flat, or from positive to inverted.
When is it attractive?: Flatteners are attractive when:
- The curve is very steep, and the trader expects it to normalize (flatten).
- The Fed is expected to pause tightening while long-end inflation expectations rise (causing long yields to rise faster than short).
- The economy is accelerating, which historically flattens the curve as short-term yields rise to meet rising long-term rates.
Example from 2021: In mid-2021, the 2-10 spread was around +150 bps (unusually steep for a recovery phase). A trader expecting the curve to flatten toward 50 bps might have shorted the 10-year and bought the 2-year. As inflation began to rise and the Fed contemplated tightening, this position would have profited through 2021–2022 as the curve flattened toward zero and inversion.
Risk: The main risk is that all yields fall together (flight to safety, recession fears, deflation), in which case the long (2-year) position profits less than the short (10-year) position loses, resulting in a net loss.
Butterfly Trades
A butterfly trade is a three-legged yield curve position designed to profit from changes in curve curvature — the shape of the middle of the curve — while hedging out directional (up/down) moves.
The structure: A butterfly typically involves:
- Long a short-maturity bond (e.g., the 2-year).
- Short two units of a medium-maturity bond (e.g., the 5-year).
- Long a long-maturity bond (e.g., the 10-year).
The notional amounts are sized such that the position is duration-neutral: the long and short notionals offset, so the position does not profit or lose much if all yields move up or down together.
How it works: The position profits if the curve becomes more "humped" — if the 5-year yield falls relative to the 2-year and 10-year, creating a convex bulge in the middle. Alternatively, it profits if the curve becomes more linear (less humped).
Example: Suppose the 2-5-10 curve is 1% – 2% – 3% (normal, linear). A trader observing that the middle of the curve (5-year) is rich (offering less yield than the 2-10 line would suggest) might construct a butterfly: short the 5-year, long the 2-year and 10-year. If the 5-year yields rise to 2.3% while the 2-year and 10-year stay flat, the trade profits.
Advantage: Butterflies allow traders to bet on curve shape without taking directional (up/down yields) risk. This is useful when a trader has a strong view on curve positioning but no strong directional view on absolute yield levels.
Risk: Butterflies are complex. The main risk is mistiming the reversion — the 5-year might remain rich for months while the trader's position loses mark-to-market value. Additionally, execution (buying and selling at favorable spreads) is critical and difficult.
Carry Trades
A simpler and more passive yield curve strategy is the carry trade: buy a bond, collect coupons, and hold it to maturity or sell it after a period of appreciation.
The structure: The classic carry trade in a steep curve is:
- Buy a longer-maturity bond, like the 10-year.
- Finance the purchase with short-term funding, like a 1-year Treasury or a repo agreement.
How it works: If the 10-year yields 4% and the 1-year yields 3%, the trader earns a 100-basis-point carry (the coupon on the 10-year minus the cost of short-term funding). As time passes, the 10-year "rolls down the curve" (matures one year and is closer to the 9-year as time advances). If the 9-year yield is lower than where the original 10-year was, the trade profits from capital appreciation. Even if yields stay flat, the trader captures the carry (coupon minus funding cost).
When is it attractive?: Carry trades are attractive when:
- The curve is steep, providing a large carry advantage to holding longer bonds.
- Volatility is low, so the risk of a sudden yield move is small.
- Funding costs (short-term yields) are low relative to longer yields.
Risk: The main risk is a parallel shift in yields (all yields rise together, compressing the curve). In this case, the long bond position loses more than the carry earns. Additionally, if the curve inverts sharply (as in 2022), the carry advantage disappears and the trader is underwater.
Duration risk: Carry trades are inherently duration-long; they assume yields will not rise sharply. A recession shock that causes a sharp rise in yields can wipe out months of carry earnings in days.
Duration Plays
Sometimes the most profitable yield curve trade is not about the curve's shape, but about the overall level of yields. A duration play bets on whether yields will rise or fall.
Long duration: A trader bullish on yields falling (expecting a recession, deflation, or Fed cuts) can buy long-duration bonds. The 20-year or 30-year Treasury offers the most duration sensitivity (biggest price swings for a given yield move). A 100-basis-point decline in the 30-year yield causes a 25%+ price appreciation for a long-dated bond.
Short duration: A trader bearish on yields (expecting rising inflation or Fed tightening) can short long-duration bonds or buy short-duration bonds. This is less profitable in absolute terms but is a hedge against a bull market rally.
When is it attractive?: Duration plays are attractive when a trader has conviction on the direction of yields. The 2022 trade of being short duration (anticipating the Fed tightening campaign) would have been profoundly profitable through the end of 2022. Conversely, being long duration from the August 2022 inversion onward would have been profitable as the 10-year yield fell from 4.2% to 3.5% over the following year.
Practical Considerations
Execution: Curve trades require buying and selling bonds or futures at favorable prices. For retail investors, this is difficult; transaction costs are high, and spreads are wide. Professional traders and dealers have advantages here.
Leverage and financing: Many curve trades use repo (repurchase agreements) to finance long positions, which introduces financing risk. If repo rates spike or funding dries up (as happened in March 2020), leveraged curve positions can unwind violently.
Hedging complexities: Curve positions are often hedged with swaptions (options on interest-rate swaps) or Treasury futures, which introduce option-pricing complexity and gamma risk (non-linear exposure to yield moves).
Mark-to-market volatility: A butterfly or steepener might be fundamentally profitable on a 18-month horizon but show losses for months while waiting for the trade to pan out. Portfolio managers and traders must have the conviction and risk tolerance to hold underwater positions.
When Professionals Use Curve Trades
Bond investors, hedge funds, and systematic traders use yield curve trades constantly:
- Pension funds use steepeners when they believe yields will fall (recession hedge).
- Banks use flatteners when they believe their net interest margin will compress.
- Bond dealers use butterflies to exploit small pricing discrepancies between segments.
- Macro traders use duration plays and steepeners/flatteners as core portfolio positions.
These trades are not academic exercises; they are real profit sources in the fixed-income world.

Steepeners, flatteners, butterflies, and carry trades are the bread and butter of curve trading. But the simplest yield curve trade is the steepener — and among steepeners, none is more common than the "curve steepener" bet made by traders who believe the Fed is done tightening.
