What is insurance?

Insurance is your financial shield — a contract that protects you or your business against unexpected events like illness, accidents, or loss. In exchange for a regular premium, the insurance company promises to compensate you when something covered by your policy goes wrong.

Think of it as transferring risk from your shoulders to a company that’s built to handle it.

Everyday examples of insurance:

  • Life insurance – Life insurance offers financial support to your family in case of your untimely death. Some policies also offer savings benefits. Looking for insurance that matches your life goals? Compare plans and get a quote in minutes.

  • Health insurance – Covers hospital bills, surgeries, and medical treatments.

  • Motor insurance – Pays for damages to your car or others in an accident.

  • Home/property insurance – Protects against damage from natural disasters, fire, or theft.

What is reinsurance?

Here’s where it gets interesting.

Reinsurance is insurance for insurance companies. It’s how insurers manage their own risk when faced with large claims — like after a natural disaster or widespread event.

When an insurance company thinks a potential risk is too big to handle alone, they pass a part of that risk to another company — called a reinsurer.

Why reinsurance is important:

  • It keeps insurers financially stable during major claims.

  • It allows them to take on more customers without overexposing themselves.

  • It spreads risk across multiple players, making the entire system more resilient.

In simple terms, reinsurance helps your insurer stay strong — so your claims are always secure.

Frequently asked questions

What is the main function of insurance?
The primary role of insurance is to provide financial protection against unforeseen risks and losses. By transferring the financial burden from the insured to the insurer, it ensures that individuals and businesses can recover from events like accidents, illness, or property damage.

How does reinsurance assist the insurance sector?
Reinsurance helps insurers manage large risks by transferring part of their exposure to other companies. It enables insurers to handle significant claims or catastrophic events, ensuring they remain financially stable while continuing to provide coverage to policyholders.

Why is reinsurance essential for insurers?
Reinsurance is crucial for insurance companies as it helps them mitigate the financial impact of large claims, such as those from natural disasters. It improves insurers' capacity to take on more policies, providing additional financial security and stability in volatile situations.

How do insurance and reinsurance differ in their structure?
Insurance directly covers individuals or businesses against risks, while reinsurance involves one insurer passing on part of its risk to another insurer. Insurance offers direct coverage to policyholders, whereas reinsurance strengthens insurers by sharing their risk and helping them manage large-scale claims.

Can you provide examples of reinsurance in action?
An example of reinsurance in practice is when an insurance company provides flood coverage but transfers part of the risk to a reinsurer due to the high potential costs of a large-scale disaster. Reinsurance spreads the risk and protects both the insurer and its clients.
