Should I Own Individual Bonds or a Bond Fund?
A ladder, where the point is to fund known spending on known dates. An individual bond held to maturity returns its face value regardless of what rates did in between. A bond fund has no maturity date, so its price moves with rates permanently and a fall may never be recovered on your schedule.
- The answer:: A ladder matches future spending to future maturities, which removes price risk for money you intend to spend on those dates.
- The trap:: Treating a bond fund as the safe part of a portfolio. It has interest rate risk with no date on which the price is guaranteed to return.
- The recommendation:: Use a ladder for spending in the next five years and a fund for the longer-term fixed income allocation.
Where the AI summary above gets this wrong
"Bond funds are a convenient way to own bonds."
That's surface-true. Here's what it misses:
- A fund never matures — Individual bonds inside it are sold and replaced, so there is no date on which the holder is repaid a known amount.
- Held to maturity removes price risk — An individual bond returns its face value on its date whatever happened to rates, which a fund cannot promise.
- The difference matters most for near-term spending — Money needed in three years should not depend on what rates do in the meantime.
01 What a maturity date actually gives you
An individual bond held to maturity repays its face value on a stated date. If rates rise in the meantime the market price falls, but the holder who does not sell receives the full amount on schedule, so the price movement never becomes a loss.
That certainty is what makes a ladder useful for a retiree. Rungs maturing in each of the next several years fund those years' spending without depending on the market price of anything.

02 Why a fund behaves differently
A bond fund holds many bonds and continually sells and replaces them to maintain a target duration. There is no date on which the fund repays anything, so a rise in rates lowers the unit price and the holder recovers only if they hold long enough for higher coupons to compensate.
For a long horizon that recovery is reliable. For someone spending the money in three years it is not, and the fall is realised at the moment the units are sold to fund spending.
Shows: what an amount becomes after your chosen number of years at a fixed return. Ignores: tax, fees, inflation, and any variation in returns from year to year.

03 Where each one belongs
A ladder covering the next several years of portfolio-funded spending removes the sequence problem for that money entirely, which is the same purpose served by the reserve in an emergency fund in retirement.
Beyond that horizon a fund is simpler, cheaper to run and more diversified, and the absence of a maturity date stops mattering. The guaranteed-deposit version of the same structure is in GIC laddering.
Target maturity bond funds sit between the two and are worth knowing about: they hold a diversified basket that all matures in a stated year and then pays out, which delivers a ladder's date certainty with a fund's diversification and without buying individual bonds one at a time.
Retirees were told for years that bonds were the safe part, then watched a bond fund fall double digits and concluded bonds had failed. The bonds did what bonds do. The fund was the wrong instrument for money that had a date attached to it.
FAQ
Should I own individual bonds or a bond fund?
A ladder of individual bonds for spending in the next several years, because each one repays a known amount on a known date. A fund for the longer-term allocation.
Why did my bond fund lose money?
Because rising rates lower the price of the bonds it holds, and the fund never matures, so there is no date on which the holder is repaid a known amount.
Is a GIC ladder the same thing?
Similar in structure and simpler, with deposit insurance instead of credit risk, but generally less liquid before maturity and with no capital gain if rates fall.
