1. **Mortality risk**: This refers to the risk that policyholders may die earlier than expected, resulting in the insurance company having to pay out life insurance benefits sooner than anticipated. This risk is prevalent in life insurance products.
*Example*: Suppose an insurance company sells a term life insurance policy to a 40-year-old individual with a coverage period of 20 years. If the policyholder passes away before the term expires, the insurance company will have to pay out the death benefit to the beneficiary.
2. **Longevity risk**: This refers to the risk that policyholders may live longer than expected, leading to the insurance company having to make annuity payments for a longer period than initially projected. This risk is associated with annuity products.
*Example*: An insurance company offers a fixed annuity to a 65-year-old individual, promising to pay a monthly income for as long as they live. If the annuitant lives well beyond their life expectancy, the insurance company will need to continue making payments for an extended duration.
3. **Natural Hedge (Offset)**: Insurance companies that offer both life insurance and annuity products can benefit from a natural hedge. The risks faced by each product type somewhat offset each other, which can help balance the overall risk exposure for the insurance company.
*Example*: Let's say an insurance company sells life insurance policies to individuals aged 30-50 (mortality risk exposure) while also selling annuities to individuals aged 65 and older (longevity risk exposure). The mortality risk from the life insurance policies is somewhat mitigated by the longevity risk from the annuity products. As people from the life insurance pool pass away earlier than expected, the annuity pool, on average, contains people who are likely to live longer, reducing the impact of mortality risk on the overall business.
4. **Residual Exposure**: Although the natural hedge can help balance the risks to some extent, it may not be perfect, and there could still be some residual exposure. This means that there may be a remaining level of risk that the insurance company needs to manage or hedge.
*Example*: Even with the natural hedge, it's possible that the mortality risk and longevity risk do not perfectly offset each other. The insurance company may still have some exposure to unexpected events, such as a higher number of policyholders living much longer than anticipated or a spike in mortality due to unforeseen circumstances.
5. **Longevity Derivatives**: To manage the residual exposure and hedge against longevity risk, insurance companies can use financial instruments known as longevity derivatives. These derivatives allow them to transfer some of the risk to other parties, thereby reducing their overall risk exposure.
*Example*: An insurance company enters into a longevity swap, which is a type of longevity derivative, with an investment bank. In this swap, the insurance company agrees to pay the investment bank a fixed amount annually. In return, the investment bank will make payments to the insurance company based on the difference between the pre-stated fixed mortality rate (an agreed-upon rate based on life expectancy) and the actual mortality rate experienced by the insurance company's annuity pool. If the actual mortality rate is higher than expected, the investment bank will make larger payments to the insurance company, helping to offset the increased annuity payout costs.
6. **Longevity Bond (Survivor Bond)**: A longevity bond is another form of longevity derivative. It involves issuing bonds with coupon payments linked to the survival rate of a defined population group. These bonds provide investors with a unique investment opportunity and allow insurance companies to transfer longevity risk to the bondholders.
*Example*: An insurance company issues a longevity bond linked to the survival rate of a specific demographic, such as males aged 80-85 in a particular region. The bond's coupon payment is tied to the number of people within that group who are still alive at periodic intervals. If the survival rate is higher than expected, the insurance company's annuity payouts may increase, but they will receive coupon payments from the bondholders to help cover the additional costs.
In summary, mortality risk and longevity risk are two critical factors that impact insurance companies offering life insurance and annuity products. While a natural hedge exists due to the opposing nature of these risks, some residual exposure remains, which can be managed using longevity derivatives like swaps or longevity bonds to transfer the risk to other parties and stabilize the insurance company's financial position.
