01 / UNDERSTANDING
Reading the news
In bond-market reporting, distinguish a yield movement, coupon income and a valuation change. When a bank portfolio is described as long duration, ask which cash flows and yield changes the measure represents. Look for the liability comparison before interpreting asset sensitivity as the whole institution's economic-value exposure.
02 / UNDERSTANDING
The concept in context
Economic-value analysis considers the present values of assets and liabilities rather than only the next period's income. Their sensitivity can differ even when nominal amounts match. Duration-based estimates simplify the yield movement and instrument behaviour; large shocks, curve changes and options can require additional analysis such as convexity or scenario valuation.
03 / UNDERSTANDING
A worked learning case
Two fictional bonds each have a face amount of 100 units, but one pays its cash flows much later. The learner compares their response to the same small hypothetical yield increase. The later-weighted bond is more price-sensitive. A bank holding it then compares that sensitivity with the present-value response of the liability used to fund it.
ORIGINAL EDUCATIONAL PRACTICE
Try it before you check.
Why can equal asset and liability face amounts still leave economic-value interest-rate risk?
Show the answer and reasoning
Their cash-flow timing and price sensitivities may differ.
Face amounts describe nominal claims, whereas economic value depends on when cash is received or paid and the rates used to discount it. Matching nominal amounts does not match those sensitivities. A duration comparison helps reveal the difference, while its assumptions and the possible effect of nonparallel yield changes still need review.
Two traps to watch for.
- Equating a bond's coupon rate with its duration.
- Treating a small-change price approximation as exact for every shock.
