The Purpose of Insurance

Life is full of unpredictable events that could potentially destroy everything we have. A fire or natural disaster can wipe out our homes and businesses in an instant. An accident could leave our families without their primary source of income overnight. A severe, prolonged, or chronic illness can decimate family wealth.

Insurance exists precisely for these situations. It’s the only tool designed to protect us from events that may not happen but, if they do, can have devastating consequences for our lives or those of our loved ones. In a moment, it can wipe out everything we own.

Why People Don’t Use Insurance

Many people choose not to insure themselves, largely due to a lack of insurance culture. While it’s true that many people in Mexico live day-to-day and may not have the financial capacity to purchase insurance, others who do have the means (middle and upper classes) either don’t get the insurance they need or choose inadequate policies.

Insurance isn’t for covering minor losses. It’s unfortunate to see people with insurance that offers a mere “USD 100 per day” for hospitalization but lack comprehensive medical expense coverage. If they develop a costly condition requiring surgeries, chemotherapy, and ongoing treatments, those “USD 100 per day” will offer little help.

Additionally, some individuals opt for lower deductibles, sacrificing comprehensive coverage. A medical expense insurance policy with a limit of 40 million pesos and a deductible of 80,000 pesos is preferable to one with a limit of 5 million pesos and a deductible of 20,000 pesos.

The deductible is an amount you can save for your emergency fund. It should be considered when setting aside funds for unexpected events. If you face a severe illness or long, expensive treatment requiring intensive care for several days, a seemingly “small” insured amount can deplete quickly. What then?

Misconceptions About Insurance

Insurance isn’t for saving or investing. While they can serve these purposes, insurance is an inefficient way to do so.

“Guaranteed savings” insurance policies typically yield close to zero real returns (sometimes even negative). Although marketed as “super” products with guaranteed retirement returns three times the contributions, the reality is that your actual gain, above inflation, is negligible.

Seguros with “investment” features, which lack a guaranteed sum, are also sold as attractive options. However, these come with hidden costs due to the different regulations governing insurance products. The actuarial calculation of premiums, including all costs and expenses, reserve constitution, and expected profitability, is detailed in a technical note submitted to the CNSF. This note remains confidential as it contains proprietary, internal information of the insurance company.

When Insurance Isn’t Ideal

Insurance is most effective and efficient for covering risks with potentially severe, financially devastating consequences. For other purposes, better alternatives usually exist.
