01 / UNDERSTANDING
Understand the idea
Explain why the same rate movement can improve one funding arrangement and squeeze another. A common market movement can create different income effects for different balance sheets. Contrast this with the error of ignoring whether the asset and funding reprice at different times. In a practical demonstration, distinguish income exposure from valuation exposure. Ask the reader to name the controlling fact and explain what additional information would be needed in a different situation, rather than only repeating terminology.
02 / UNDERSTANDING
The concept in context
Interest-rate risk arises when rate changes affect asset values, funding costs or income differently. A bank’s exposure depends on repricing schedules and cash-flow characteristics, rather than simply on whether interest rates rise or fall. Compare when assets reprice with when liabilities reprice, then separately consider changes in the market value of fixed cash flows.
A simplified gap illustration excludes behavioural responses, hedges and other features that can materially alter actual bank exposure. A useful study check is to place asset and liability repricing dates together, then distinguish income exposure from valuation exposure. Explain why the method fits the stated facts before applying it to a changed situation.
03 / UNDERSTANDING
A worked learning case
A fictional bank earns a fixed 8 on a 100-unit asset and initially pays 3 on matching funding. Its simplified annual spread income is 5. If funding reprices to 5 while asset income remains fixed at 8, spread income falls to 3. The example isolates a timing mismatch rather than predicting every bank’s response to rising rates.
ORIGINAL EDUCATIONAL PRACTICE
Try it before you check.
How much does the stated spread income fall after funding reprices?
Show the answer and reasoning
2 units.
Initial spread income is 8 minus 3, equal to 5. After the funding cost rises, it is 8 minus 5, equal to 3. The difference is 2. Because asset income is held fixed in the example, the funding repricing is not offset; a different repricing structure could produce another result.
Two traps to watch for.
- Assuming higher rates always increase a bank’s net interest income.
- Ignoring whether the asset and funding reprice at different times.
