Article Summary

• Parametric insurance can provide flexibility in addressing risks that are difficult to insure.
• Parametric insurance provides timely payouts after a qualifying event occurs.
• When paired with traditional insurance, parametric coverage can help enhance a risk management strategy.

What is parametric insurance?

Parametric insurance is an index-based insurance solution. While traditional insurance is driven by actual loss, parametric insurance is based on whether a predefined event occurs, as measured by an objective parameter or index. A parametric insurance policy outlines the specific event or thresholds that will trigger payment and when those parameters are met a predetermined payout is triggered. Payout structures can be binary (a fixed amount once a threshold is met) or tiered, where the payout increases based on the severity of the triggering event.

Effective parametric insurance structures typically rely on three key elements:

• Triggering events must be fortuitous
• Events must be able to be modeled
• Any thresholds being applied need to be objective, readily available, and reported by an independent third party

Current uses for parametric insurance generally focus on natural catastrophes – things like hurricanes (certain wind speeds or category), earthquakes (certain magnitude), floods (certain water depth). Based on the previous criteria you can see why these are a good fit. The timing and severity of these events cannot be predicted with certainty, yet these events can be modeled with reasonable reliability. Finally, those types of events have independent third parties that are going to report various statistics about the event. The use of independent, third-party data sources is critical to ensure transparency, consistency, and avoid disputes regarding whether a trigger has occurred. These characteristics make natural catastrophes particularly well suited for parametric insurance.

In corporate risk management programs, parametric insurance is often used alongside traditional insurance or within captive insurance structures to provide rapid liquidity following an event and to address coverage gaps that may not be covered by conventional policies. This is particularly relevant for risks such as non-damage business interruption or supply chain disruption.

Compare and Contrast

To highlight the differences between traditional insurance and parametric insurance let’s look at an example. Assume a homeowner in Florida experiences a category 5 hurricane that causes damage to their home.

With traditional insurance, the insured would need to document their loss, submit a claim, and wait for the insurance company to evaluate and adjudicate the claim and determine the final amount to be paid in accordance with the policy. The payment amount is generally correlated with the actual amount of the underlying property loss. This process could be lengthy, especially after a catastrophic event where the insurance company is processing a large number of claims.

With parametric insurance, the insured doesn’t have to submit a claim for payment to be initiated. A parametric policy in this scenario might specify that if a hurricane impacts a defined geographic area, based on parameters such as wind speed thresholds reported by an independent data provider, then a payout will be made. Because the hurricane that hit was Category 5, as reported by an independent agency, the insurer recognizes that the trigger has been met and initiates payment. There is no need to provide evidence of actual property loss. The payment in this circumstance is a predetermined amount and could be more or less than actual loss.

In simple terms, traditional insurance answers “How much did you lose?” while parametric insurance answers “Did the event occur?”.

Benefits of Parametric Insurance

Why might someone decide to use parametric insurance?

• Rapid payout capability, as payments are triggered automatically once the predefined parameter is met, without the need for claims adjustment.
• Helps cover hard to insure losses, not just property losses. For example, a business owner in Florida likely has property coverage on their business location. As part of their risk management strategy, they may want coverage for business interruption if a hurricane occurs. Parametric insurance can be a good fit because once the triggering event occurs, a payout is triggered, providing liquidity. The business owner doesn’t have to wait to prove loss of income and can use the payout to help pay employees, start repairs, and fund operations.
• Similar to traditional insurance, parametric policies can be highly customizable.
• A company could have a very tailored policy that integrates with existing traditional coverage. On the other end of the spectrum there are also off-the-shelf policies that organizations can implement more quickly.

Cautions of Parametric Insurance

What are some things to be aware of regarding parametric insurance:

• One important consideration is “basis risk,” which arises when the parametric trigger does not perfectly align with the insured’s actual loss experience. Because the payout is predetermined, an insured’s actual loss could be significantly higher or lower than the payout amount. Managing basis risk is a key consideration when designing a parametric policy and often involves carefully selecting trigger metrics and thresholds that closely align with the insured’s exposure. To mitigate basis risk, parametric policies are often designed using carefully selected trigger metrics, geographic parameters, and multiple data points that more closely align with the insured’s actual exposure.
• Parametric insurance may sometimes be viewed as more costly than traditional insurance. This comparison can be difficult because traditional insurance indemnifies actual loss, whereas parametric insurance addresses exposure tied to defined triggering events rather than reimbursing actual losses.
• Parametric insurance can’t cover risks where there are not reliable data sources provided by a third party. Not all risks can be addressed using a parametric structure.
• While parametric insurance coverage can be tailored to specific needs, it can also be complex to design. It may take additional time and effort to align the structure with the intended risk exposure.

What is Coming for Parametric Insurance

Parametric insurance has historically been used for natural catastrophes, but emerging use cases are expanding beyond these perils, including:

• Business interruption
• Cloud outages
• Extreme temperatures
• Extreme rainfall or snowfall
• Supply chain disruptions

Even within its existing applications, as the frequency and severity of natural disasters increase, parametric insurance may become relevant to a broader set of organizations.

In practice, parametric insurance is often used alongside traditional insurance programs or within captive insurance structures to provide additional liquidity and reduce volatility. As you evaluate your risk management strategy and are evaluating options to address potential coverage gaps, parametric insurance can serve as a valuable complement to traditional insurance by improving liquidity, reducing claims friction, and addressing coverage gaps.

Frequently Asked Questions About Parametric Insurance

What is parametric insurance?
Parametric insurance is a type of insurance that provides coverage based on whether a predefined event occurs, as measured by an objective parameter. When the defined trigger is met, a payout is automatically made.

How is parametric insurance different from traditional insurance?
Traditional insurance indemnifies the insured for actual losses, typically tied to physical damage or measurable financial loss, and requires proof of loss. Parametric insurance, by contrast, is based on whether a defined event occurs, regardless of the actual loss incurred

What types of events can parametric insurance cover?
Parametric insurance is most widely used to provide coverage for natural disasters like earthquakes, wildfires, hurricanes, and floods.
