Yield curve strategies: riding the curve, barbells, and bullets
Fixed income investors face a choice that long-only equity investors do not: at every maturity along the yield curve, they can hold a different bond. The choice—duration, credit, sector—determines the portfolio's expected return and risk profile. Yield curve strategies are the standard frameworks for making this choice systematically, each with specific assumptions about how the curve will evolve and what compensation the investor will earn for taking different shapes of risk.
What yield curve strategies are
Yield curve strategies are fixed income portfolio constructions that exploit the term structure of interest rates—specifically, the shape of the yield curve as it slopes from short to long maturities. The standard families are: riding the curve (holding intermediate-duration bonds and selling them as they roll down the curve), barbell strategies (concentrating exposure at the short and long ends), bullet strategies (concentrating exposure at a single intermediate maturity), and ladder strategies (spreading exposure evenly across maturities).
Each strategy makes a specific bet about how the yield curve will move. Riding the curve assumes the curve will remain upward-sloping and roughly stable, so that an intermediate-duration bond's yield will fall as it ages toward maturity. Barbells and bullets bet on different parts of the curve flattening or steepening. Ladders bet on nothing specific and produce a balanced exposure across the curve.
The strategies have been institutional staples for decades. They are most relevant for fixed income allocations large enough to hold multiple separate maturities; for portfolios using bond ETFs, the equivalent decisions are about which ETFs (short-duration, intermediate, long-duration, aggregate) to combine and in what proportion.
How each strategy works
Riding the curve. The strategy holds bonds with maturities longer than the investor's horizon and sells them before maturity. As the bond ages, its remaining time to maturity shortens, and (if the curve is upward-sloping) its yield falls—pulling its price up. The investor captures the price appreciation in addition to the coupon. The strategy works when the yield curve is positively sloped and stable; it backfires if the curve flattens or inverts during the holding period, because the rolled-down yield is no longer below the entry yield.
Barbell strategy. The portfolio combines very short-duration bonds (cash equivalents, T-bills) and very long-duration bonds (long Treasuries, long corporates), with no intermediate exposure. The combination produces an average duration similar to a portfolio with intermediate-only exposure but with different sensitivity to curve shape. The barbell outperforms the bullet when the curve flattens (long bonds rally, short bonds hold value); the bullet outperforms when the curve steepens.
Bullet strategy. The portfolio concentrates at a single maturity—typically intermediate, where the curve's slope is steepest in normal regimes. The bullet captures the highest yield-per-duration along the curve and is the simplest construction; the trade-off is that it has no exposure to either the very short or very long ends, and is therefore vulnerable to specific shapes of curve movement that a barbell would catch.
Ladder strategy. The portfolio holds bonds at evenly-spaced maturities—for example, 1-year, 2-year, 3-year, … 10-year bonds with equal weight. As each year passes, the shortest bond matures and the proceeds are reinvested at the longest end of the ladder. The strategy produces a constant duration profile and is the simplest passive yield-curve strategy.
What the evidence shows
The empirical case for riding the curve is strongest in normal upward-sloping yield-curve regimes. Over 1970–2020 in the US, a strategy holding intermediate-duration Treasuries and selling them after one year produced higher total returns than holding short-duration Treasuries to maturity, with a small amount of additional volatility. The roll-down premium has been documented in many studies, including Ilmanen's Expected Returns and the broader fixed-income academic literature.
Barbell and bullet strategies have produced similar long-run returns over multi-decade samples, with the relative performance depending on the realised path of the curve. In flattening regimes, barbells outperform; in steepening regimes, bullets outperform. The pre-2022 environment of persistent flattening favoured barbells; the post-2022 period of curve normalisation has favoured bullets.
Ladders are typically dominated on a pure-return basis by the alternative strategies (because they include some less-attractive maturities) but offer the implementation simplicity of a passive approach. The strategy's main use case is for retail investors managing their own bond portfolios at scale where the alternatives' active management is impractical.
Limitations and trade-offs
All yield-curve strategies depend on the assumption that the historical curve dynamics will continue. Regime shifts that change the typical curve shape—central bank yield-curve control, persistent inversion, fundamental change in monetary policy framework—can invalidate the historical pattern that a strategy is calibrated to exploit. The 2020–2022 period saw multiple such shifts and produced losses for strategies calibrated to pre-2020 norms.
Implementation cost matters more in fixed income than in equities. Bond bid-ask spreads are wider, ETF tracking error can be material for thinly-traded duration buckets, and the transaction costs of frequent rebalancing can erode the strategy's expected return. The simplest strategies (ladders, bullets) carry the lowest implementation cost; the strategies that require frequent rebalancing (riding the curve) carry the highest.
Yield-curve strategies also do not address credit risk. The frameworks assume the underlying instruments are default-free (or that credit risk is constant); they describe how to choose duration along a single credit-class curve. Mixing duration and credit decisions in a single portfolio requires additional analytical structure beyond the basic yield-curve frameworks.
Yield curve strategies in pfolio
Yield curve strategies—riding the curve, barbells, and bullets—can be expressed in pfolio using bond ETFs and bond futures across the available duration spectrum. The Assets page lists fixed income instruments with their duration and yield characteristics where available, and portfolio-level interest rate exposure is visible in pfolio Insights.
