FIXED- INCOME SERIES · ARTICLE IV·RISK & RATES
Bonds are supposed to be the steady part of a portfolio. So why have some of them fallen so much? The answer is a single concept worth understanding.
Many investors hold bonds precisely because they expect them to be the calm part of the portfolio. So it can be unsettling to watch a high-quality bond fall in value. The explanation is not that something went wrong with the bond, it is a feature of how bonds work, captured in one word: duration.
The seesaw
Bond prices and interest rates move in opposite directions. When prevailing rates rise, existing bonds which pay the older, lower rate become less attractive, so their market price falls until their yield is competitive again. When rates fall, the reverse happens. This is the fundamental seesaw of fixed income, and it operates regardless of the credit quality of the bond.
Why “how long” is the whole story
Duration measures how sensitive a bond’s price is to a change in rates, and it is driven largely by time. A bond maturing in two years will have its principal returned soon, so a change in rates has limited room to affect its price. A bond maturing in fifteen or twenty years locks in today’s rate for a long stretch, so a change in prevailing rates has far more time - and far more price - to work against it.
This is why a portfolio concentrated in long-maturity bonds can feel the pain of rising rates so sharply, while a shorter-dated portfolio tends to absorb the same move with far less drama. A one-percentage-point rise in rates does not treat all bonds equally; it lands hardest on the longest ones.
Two bonds of identical quality can behave completely differently when rates move. The difference is time.
What an investor can do about it
Understanding duration turns an alarming number on a statement into a manageable variable. Among the levers available:
· Shortening duration, favoring shorter maturities, reduces sensitivity to further rate increases, at the cost of locking in less yield for less time.
· Laddering maturities so that bonds come due at staggered intervals, providing regular opportunities to reinvest as conditions change.
· Pairing bonds with other assets: a balanced mix of stocks and bonds can, in some environments, be steadier than an all-bond portfolio when rates are volatile.
· Matching duration to time horizon and purpose, so the structure of the portfolio reflects when the money is actually needed.
· “Moderate risk” does not automatically mean “all bonds.” In a volatile-rate environment, a thoughtfully balanced portfolio can carry less risk than one that is entirely fixed income but heavily concentrated at the long end. The goal is not to avoid duration- it is to choose it deliberately.
