Duration risk is one of the least understood parts of a fixed-income portfolio, and one of the most consequential. Two bonds can carry identical credit quality and still respond to the same interest rate move in completely different ways. From a planning perspective, understanding duration is what separates a portfolio built to withstand a rate cycle from one that simply hopes to avoid it.
In my work with families across Northeast Iowa, bonds are usually described as the "safe" part of a portfolio. That's true in terms of credit risk, but it isn't the whole story. In 2022, investors got a clear lesson in the other risk bonds carry: duration.
What does duration actually measure?
Duration measures how sensitive a bond's price is to a change in interest rates. The longer a bond's duration, the more its price moves when rates change, in either direction. A bond maturing in two years barely reacts to a rate hike. A bond maturing in twenty-five years reacts sharply.
This isn't a credit-quality distinction. Two U.S. Treasury bonds carry the same government backing. The difference is how long you're locked in, and that alone can separate a modest loss from a severe one.
How much did duration actually matter in 2022?
As the Federal Reserve raised rates aggressively through 2022, long-term and short-term Treasuries, both backed by the same government and both considered "safe," moved in very different directions.
| Treasury Type | Maturity | 2022 Total Return |
|---|---|---|
| Long-Term Treasuries | 20+ years | -31.4% |
| Short-Term Treasuries | 1-3 years | -3.9% |
That's a 27-point gap between two bond investments that many people would have described, before 2022, as basically the same thing. They were not the same thing — one simply had far more duration risk built in.
Why does this matter if you're retired or close to it?
For someone drawing income from a portfolio, a 31% drop in the "safe" bucket isn't a paper loss you can simply wait out, especially if withdrawals are happening at the same time. Sequencing matters as much as the average return.
- Bond funds with longer average maturities carry more interest-rate sensitivity, regardless of credit quality
- A "bond fund" label alone doesn't reveal duration — two funds with similar names can behave very differently in a rate-moving year
- Blending short and long maturities is one common way to manage this tradeoff, though it does not eliminate it
How does a fiduciary advisor think about duration in a retirement portfolio?
At our practice, fixed-income decisions are evaluated as part of the same six-pillar framework we apply to every planning area: taxes, investments, estate planning, retirement income, risk management, and behavioral finance. Duration is rarely a decision made in isolation — it's weighed against income timing, tax considerations, and how much volatility a household can tolerate in a given year.
A fiduciary standard doesn't eliminate the tradeoff between higher potential yield and greater rate sensitivity. It does mean that tradeoff is made deliberately, with full disclosure, rather than assumed away because the word "Treasury" or "bond" sounds inherently safe.
