Bonds Laddering And Bond ETFs
What Is Bond Laddering?
Bond laddering is an investment strategy where we buy bonds with staggered maturity dates, so that a portion of the portfolio matures at regular intervals. It helps manage interest rate risk, creates predictable income, and gives you access to cash over time.
If we build the ladder with corporate bonds, we can also diversify across sectors, such as financial services, technology, and energy, so your capital isn't tied to the fortunes of any single industry.
Benefits
Reduces interest rate risk: As bonds mature, proceeds are reinvested at current rates. If rates have risen, you capture the higher yields.
Predictable cash flow: Principal and interest arrive at set intervals.
Diversifies maturity risk: You aren't locked into a single rate or time horizon.
Fully customizable: We can tailor the ladder's structure, maturities, and sector mix to your goals.
Using Bond ETFs
If you'd rather not manage individual bonds, we can build a similar ladder using bond ETFs, such as those from iShares. This gives you broad diversification, easy liquidity, and lower minimums without the hassle of buying and holding individual bonds.
With ETFs, we use portfolio math to blend funds and hit a target duration. Duration measures a bond's sensitivity to interest rate changes, so matching it to your needs and risk tolerance is critical.
Example: Say ETF A has a duration of 2.6 and ETF B has a duration of 5.8, and we want a portfolio duration of 4.0. Let w be the weight in ETF B:
2.6 × (1 − w) + 5.8 × w = 4.0
w = (4.0 − 2.6) ÷ (5.8 − 2.6) ≈ 43.75%
So we'd hold roughly 56% in ETF A and 44% in ETF B to land at a 4.0 duration.
