Bond Strategies

Beyond purchasing a bond index fund or holding individual bonds to maturity, sophisticated investors deploy structured strategies to optimize yield, manage reinvestment timing, or match specific liabilities. This chapter explores the toolkit: from the simplicity of a buy-and-hold ladder to the complexity of active yield-curve positioning.

Why strategies matter​

A bond strategy answers a specific question about your circumstances: How do I turn a lump sum into predictable income? How do I reduce reinvestment risk? How do I align my assets with a future liability? Different strategies suit different goals.

A young investor saving for retirement (40+ years away) might use a barbell: half short (for stability), half long (for growth). A retiree needing income in 10 years might build a cashflow-matched portfolio, where each bond matures when the money is needed. A professional pension fund might use duration matching to hedge interest-rate risk while maintaining flexibility in bond selection.

The core insight is this: your bond portfolio's structure should reflect your liability structure and your beliefs about interest rates and the future.

Passive strategies: predictable returns​

The first half of this chapter covers passive, buy-and-hold strategies. These are:

Ladders — equal allocations across maturities (2y, 4y, 6y, 8y, 10y), with reinvestment at the long end every few years. Simple, mechanical, suitable for most investors.

Barbells — concentration at short and long maturities, with little in the middle. Captures yield curve slope while maintaining flexibility. Slightly more complex than a ladder but still passive.

Bullets — all bonds mature on the same date. Maximum simplicity, maximum inflexibility. Ideal for matching a known, single obligation (college payment, mortgage payoff).

Laddering mechanics — the day-to-day details of rebalancing, handling coupons, tracking maturities, and maintaining your chosen structure.

Each has trade-offs: ladders are more complex to set up but more flexible; bullets are simplest but rigid. The 3-5-7-10 ladder is a practical middle ground for most individuals.

Liability-matching strategies: protecting against uncertainty​

When you have a known future obligation (education, pension payout, bond sinking fund), matching your assets to that liability eliminates both reinvestment risk and interest-rate risk.

Cashflow matching — align bond maturities and coupons with specific liability payments. When the bond matures, the principal funds the obligation. No rebalancing needed. Zero flexibility.

Immunisation — match the duration of your assets to the duration of your liabilities. Interest-rate changes create offsetting effects (price loss offset by reinvestment gain), protecting your surplus. Requires periodic rebalancing but offers flexibility in bond selection.

Duration matching — a practical variant of immunisation. Rebalance quarterly or semi-annually to maintain duration alignment. Suitable for ongoing, multi-year liabilities (pensions, annuities).

Liability matching is essential for institutional investors (pension funds, insurance companies) and useful for individuals with substantial, known future obligations.

Active strategies: seeking excess returns​

The second half of the chapter turns to active management: timing trades to capture returns beyond coupon income.

Rolling down the curve — buy a longer-dated bond, sell it a few years later as it has aged and moved down the curve, capturing a price gain. Works best in steep curve environments and requires discipline to avoid rate risk.

Sector rotation — move between Treasuries, corporates, and municipals based on valuations. When credit spreads are wide (corporates cheap), tilt toward corporates; when tight, tilt toward Treasuries.

Credit selection — research individual bonds to identify those likely to be upgraded (buy before upgrade) or downgraded (sell before downgrade). Requires expertise and is time-intensive.

Yield-curve positioning — make directional bets on the curve's shape (steepening, flattening). Buy long bonds if you expect the curve to steepen; buy short bonds if you expect flattening. Complex, requires conviction, and is best left to professional traders.

Active strategies offer higher potential returns but also higher costs (trading fees, taxes, opportunity cost of being wrong). Most active managers underperform passive strategies after fees, so active management should only be attempted by investors with strong conviction and skill.

Choosing a strategy​

Ask yourself:

  1. Do I have a known, fixed liability? (e.g., college payment in 10 years) → Use cashflow matching or a bullet.

  2. Do I need ongoing income or flexibility? (e.g., retirement withdrawals or goals that might change) → Use a ladder or barbell.

  3. How much time and expertise do I have? → Passive laddering requires minimal monitoring; active strategies require research and discipline.

  4. What is my outlook on interest rates? → Neutral or uncertain → passive. Strong conviction on rates or curve shape → active.

  5. What is my tax situation? → Taxable account → focus on efficiency (hold to maturity, minimal trading). Tax-deferred account → active strategies are less costly.

How to read this chapter​

For beginners: Start with "Buy-and-Hold Bond Laddering" and "Laddering Mechanics." Learn the 3-5-7-10 template. Build a simple ladder for your bond allocation. Stop there.

For intermediate investors: Read the full ladder section, then the liability-matching section (especially "Laddering for Retirement Income" if you are retirement-focused). Consider a barbell or bullet if your situation calls for it.

For advanced investors: Study all passive strategies first, then explore liability matching (cashflow matching or immunisation). Finally, if you have conviction, read active strategies (rolling down, sector rotation, curve positioning). But remember: most active strategies underperform after costs.

For institutional investors (pension funds, insurance companies, endowments): The entire chapter is relevant. Liability matching and duration strategies are essential. Active strategies may add value if you have a large team and deep expertise.

What's in this chapter​

How to read it​

Start at the beginning if you are unfamiliar with bond strategies. The chapter progresses from simplest (buy-and-hold laddering) to most complex (yield-curve positioning).

If you have a specific goal in mind—matching a liability, maximizing income, simplifying management—jump to the relevant section:

  • Retirement income: Laddering for Retirement Income, Cashflow Matching.
  • Simplicity: 3-5-7-10 Year Ladder, Bullet Strategy.
  • Flexibility and yield: Barbell Strategy, Rolling Down the Curve.
  • Active management: Active Bond Management Strategies, Yield-Curve Positioning.

Most individual investors benefit from a passive ladder or barbell. Passive strategies are proven, require minimal monitoring, and have low fees. If your circumstances are unusual or you have strong market convictions, consider active strategies—but only if you are prepared to do the research and accept the costs.

The toolkit in this chapter will serve you whether you are a novice saving for a goal 10 years away or an experienced investor managing a complex liability structure. Choose the strategy that fits your situation, build it deliberately, and execute with discipline.
