Explained on 26 October 2026. This is an educational answer drawn from the dated article below; examples are hypothetical unless a specific source observation is identified.
How it works
For a bond or fund sold before maturity, the available market price matters. Longer-duration exposure can react more strongly to a comparable yield change under simplified assumptions. A benchmark’s maturity-bucket change should therefore be investigated with actual duration and pricing rather than called risk-free from its issuer label alone.
A simple example
Using a simplified approximation, a hypothetical modified duration of six years and a parallel 0.25 percentage-point yield rise imply about a 1.5% price decline before carry and convexity. This is a scenario, not the measured impact of the index review.
What to check
- Read the maturity and duration disclosures.
- Match exposure to the withdrawal horizon.
- Assess credit and interest-rate risks separately.
