The percentage change in the value of an asset or liability resulting from a 100-bps change in interest rates is directly proportional to its duration but is unaffected by the corresponding percentage change in interest rates.

Using USD 100 million of cash to pay a cash dividend will not affect the overall asset duration of the bank.

A prepayable mortgage loan has a higher duration than an identical non-prepayable loan and is typically more sensitive to overall interest rate changes

The sensitivity of assets and liabilities to changes in interest rates is greater when the coupon is lower, the duration is higher, or the overall level of interest rates is lower.
