What does it mean if a mortgage protection policy is described as 'interest rate sensitive'?

The term 'interest rate sensitive' in the context of a mortgage protection policy implies that the policy's financial performance and potentially its payout are linked to changes in mortgage interest rates. If a policy is described this way, it indicates that the guaranteed coverage might not adequately cover the full mortgage amount if interest rates increase.

When mortgage interest rates rise, the amount owed on a mortgage can become larger, especially if the mortgage terms involve variable rates. This increases the likelihood that the sum assured by the policy could fall short of the outstanding mortgage balance at the time of a claim. Therefore, the implication is that the policy might not fully pay off the mortgage in the event of the policyholder's death or disability if interest rates have increased and the mortgage balance has subsequently grown.

The other options either misinterpret the connection of interest rates to the policy or describe general features unrelated to how interest rates affect the value of the mortgage protection coverage. For example, while premiums might fluctuate with interest rates in some products, that is more indicative of a variable premium structure rather than tying directly to whether the policy will cover the outstanding mortgage balance.
