What is Insurance and Reinsurance? Everything You Need to Know

Have you ever wondered how insurance companies protect themselves from massive losses? Just like you buy insurance to safeguard your car or home, insurers need their own safety net. So the question arises: What is insurance and reinsurance?

Think of insurance as your financial shield against life's unexpected curveballs, while reinsurance is the backup plan for that shield. It is a fascinating world of calculated risks and shared responsibilities that keeps the entire system running smoothly.

Whether you are curious about protecting your assets or understanding how the insurance industry stays afloat during catastrophic events, this blog will help you understand the differences.

What is Insurance?

Before we explore the difference between reinsurance and insurance, we need to understand their meanings. Insurance refers to a legal agreement between a policyholder and an insurance company.

When you buy insurance, you agree to pay a set 'premium' in return for financial protection. For instance, if you want health insurance, you must pay a certain amount so that when a medical emergency occurs, you do not have to worry about your finances.

However, there are many terms and conditions in this legal agreement that you should be aware of before buying any policy.

What Does Reinsurance Mean?

Just like you buy insurance to protect yourself or your assets from unfortunate events, insurance companies also need risk management coverage. Therefore, reinsurance can be dubbed as the insurance for insurance companies.

When searching for what is insurance and reinsurance, you must know that although they sound similar, they both operate at different levels.

Reinsurance does not provide coverage for insurance companies. Instead, they agree to share the loss or risk that insurance companies may face due to a large claim.

What is Insurance and Reinsurance: Quick Comparison

To clear the confusion between what is insurance and reinsurance, let us take a look at the table below:

Now that we know insurance vs reinsurance, let us understand their different types and how they work.

What are the Types of Insurance?

General Insurance

General insurance, often termed non-life insurance, refers to protection against unexpected damage or losses to your health and assets. There are usually 4 main types of general insurance: health insurance, motor insurance, travel insurance and home insurance.

Bajaj General Insurance offers comprehensive policies in all segments, helping you protect your finances and have peace of mind.

Life Insurance

Life insurance, as the name implies, safeguards a family's finances in the event of the policyholder's death. Often referred to as the 'death benefit', it ensures that your family does not face financial hardship. In this, you have to pay regular premiums in exchange for a lump sum.

There are various types of life insurance policies, including term life, ULIPs, permanent life policies, child life policies, endowment plans, and others.

What are the Types of Reinsurance?

Treaty Reinsurance

When multiple primary insurers come together under one umbrella, it is known as a treaty reinsurance. These insurers sign a treaty where the primary insurer takes only a part of the liability, protecting their business and cutting losses.

For example, if the primary insurer agrees to take 1% of a projected risk of ₹10 crore, they would only have to pay ₹1 crore. The rest would be divided amongst the reinsurers.

If the primary insurer did not sign a treaty reinsurance, then they would have to pay ₹10 crore themselves.

Facultative Reinsurance

Facultative reinsurance is a type of reinsurance where one insurer cannot cover a single risk or a set of risks at one go. For example, you buy insurance on your corporate office complex for a sum insured of ₹90 crore.

However, your insurer realises that if you claim, they will not be able to pay out the 90 crore at one go. Therefore, they test the market and find reinsurers who can help pay the rest.

This is generally a one-time agreement between the 2 companies and only covers 1 transaction.

Loss-Occurring Reinsurance

In this type of insurance, the primary insurer buys coverage which protects them from losses within the policy period. It takes into consideration the date of loss rather than the time the insurance policy was underwritten.

Suppose an insurance provider gives property policies. They buy a reinsurance policy, which starts on January 30, 2025 and ends on January 29, 2026.

If the primary insurer faces a loss on January 1st 2026, it will be covered. However, if it happens on 2nd February 2026, they cannot file a claim for it.

Risk-Attaching Reinsurance

Unlike the loss occurring reinsurance, risk attaching reinsurance provides coverage based on the date of issuance or renewal. Suppose you are a primary insurer who bought a risk attaching reinsurance policy on September 20, 2025.

The policy is valid for a year. Within this year, you sold a home insurance with a risk of ₹10 crore. However, you face a loss after the policy year ends.

According to risk-attaching clauses, you will still be compensated since the insurance you sold was within the policy period.

Proportional Reinsurance

 In proportional reinsurance, both the primary insurer and reinsurer share premiums and losses up to an agreed-upon percentage. For instance, in a 70/30 agreement between an insurer and reinsurer, the reinsurer receives 30% of the premiums and is responsible for covering 30% of the losses.

There are 2 types in this: quota share and surplus share. Quota share works on a fixed percentage for all insurance policies. For example, your reinsurer may want a 50/20 share on all policies you sell.

On the other hand, your reinsurer covers your excess risk in surplus share. This means they only cover what you are unwilling to cover.

Non-Proportional Reinsurance

Lastly, a non-proportional reinsurance gives coverage for the losses of the primary insurer once they exceed an agreed-upon limit. Unlike proportional reinsurance, the reinsurer does not get any shares.

The concept is similar to indemnity insurance plans. For example, you, a primary insurer, have agreed that you will cover losses up to ₹10 crore. You buy a policy which gives coverage of ₹30 crore.

If you face a ₹20 crore loss, you will cover the ₹10 crore from yourself, while your reinsurer will take care of the remaining ₹10 crore.

The Bottom Line

Understanding what is insurance and reinsurance empowers you to make smarter financial decisions and appreciate the complex safety nets protecting our economy.

While insurance guards individuals and businesses, reinsurance ensures insurers can honour their promises even during catastrophic events.

Together, they create a resilient system that spreads risk and provides peace of mind. Now that you have got the basics down, you are better equipped to navigate your own insurance choices confidently with Bajaj General Insurance.
