Why Parametric?

Traditional insurance asks what you lost. Parametric insurance asks whether an agreed event occurred.

Consider what happens after a significant weather event.

Under a traditional indemnity insurance policy, the event is only the beginning of the claims process. The insured must determine what was damaged, document the loss, establish that the loss is covered, quantify its financial value, and submit a claim. The insurer must investigate the circumstances, interpret the policy, determine causation, evaluate exclusions and deductibles, adjust the loss, and ultimately agree on the amount that should be paid.

That process serves an important purpose. Traditional insurance is designed to indemnify the insured for an actual covered loss and determining that loss can require judgment.

But judgment takes time.

For a business experiencing the financial consequences of adverse weather, time may be precisely what matters. A contractor whose project has lost ten working days to rain does not necessarily need another process to establish that rain occurred. A renewable energy producer experiencing unusually low wind does not need to demonstrate physical damage to a turbine to experience a financial loss. An agricultural business affected by insufficient rainfall may suffer economically long before the full consequences can be established through a traditional claims process.

Parametric insurance approaches the problem differently.

The parties agree in advance on the event that matters and the financial response if it occurs. The trigger might be rainfall above a specified level, temperature beyond an agreed threshold, wind below a defined measure, river height, snowfall, drought conditions, or another independently observable parameter. The measurement methodology, location, coverage period, thresholds, and payment structure are established when the coverage is created.

Then the weather occurs.

If the agreed parameter is triggered, the contract determines the payment.

The difference is fundamental. Rather than reconstructing the loss after the event, much of the difficult work has been moved before the event. The parties have already agreed on what will be measured, how it will be measured, what constitutes a triggering event, and what the financial response will be.

This can dramatically simplify settlement.

The attraction to the insured is not simply speed, although speed can be important.

It is certainty of process.

Before purchasing the coverage, the insured can know what is being measured, where it is being measured, what threshold matters, and what payment will result if that threshold is reached. The insured and insurer are not waiting until after the event to begin determining what the contract means economically.

That can also make parametric insurance useful for exposures that traditional property insurance was not designed to address.

Weather can create financial loss without creating physical damage. Rain can delay construction. Heat can reduce productivity. Drought can reduce agricultural output. Insufficient snowfall can affect tourism revenue. Low wind can reduce renewable energy generation. In each instance, the business may suffer economically even though there is no conventional damaged asset around which to construct an indemnity claim.

Parametric insurance allows coverage to be designed around the financial consequence of a measurable event, rather than requiring the insurance solution to begin with physical damage.

That flexibility is one reason parametric insurance is so important to the Weather Risk Economy.

There is, however, a tradeoff.

A parametric payment is determined by the agreed trigger, not by the insured’s subsequently determined actual loss. The two therefore may not correspond perfectly. An insured could experience a meaningful financial loss without the parameter reaching the required threshold, or a trigger could occur when the insured’s actual loss is less than the contractual payment. This difference is commonly described as basis risk.

Good parametric insurance design therefore depends upon more than selecting an easily measured weather variable. The trigger must have a meaningful relationship to the financial exposure the insured is trying to manage. Historical analysis, location, thresholds, payout structures, coverage periods, and underwriting all matter because the objective is to design a contract whose behavior reasonably reflects the underlying economic risk.

This is where ClimateDelta and the Program Foundry become particularly relevant.

The objective of the Program Foundry is not simply to create more parametric policies. It is to develop programs in which weather intelligence, exposure analysis, program design, underwriting, pricing, administration, capital, and settlement operate together. The better the relationship between the measurable parameter and the insured’s actual financial exposure, the more useful the coverage can become.

And once a program is operating, the settlement process itself can become part of the platform. ClimateDelta can monitor the agreed weather conditions, apply the contractual terms, identify when a trigger has occurred, calculate the corresponding payment, and support the administrative process required to complete settlement.

The experience for the insured can therefore be fundamentally different.

The insured does not purchase protection hoping that, after an adverse weather event, everyone will eventually agree on the value of the loss. The insured purchases a contract in which the event and financial response have been defined in advance.

Measure first. Agree in advance. Settle objectively.

That is the essential appeal of parametric insurance.
