Parametric Insurance — Trigger-Based Cover

Parametric Insurance:
Rapid Settlement Without Loss Adjustment

Parametric insurance pays a pre-agreed amount when a measurable index — rainfall, wind speed, earthquake intensity, temperature — reaches a defined threshold. No loss adjustment, no adjuster visits: payment follows the trigger, enabling operational response within days of an event.

How It Works

The Parametric Mechanism: Index, Trigger, Payment

Traditional insurance is indemnity-based: you suffer a loss, a claims adjuster measures it, and the insurer pays the assessed amount. Parametric insurance works entirely differently. The policy defines an objective, measurable index — a physical parameter like cumulative rainfall at a named weather station, wind speed at a defined location, or peak ground acceleration on an earthquake intensity scale. A trigger threshold is agreed in advance. When the index reaches or breaches that threshold during the policy period, the insurer pays the pre-agreed amount — automatically and without requiring proof of actual loss.

The Key Advantages

Speed: Payment typically within days to weeks of a qualifying trigger event — not months. Certainty: The insured knows exactly what they will receive if the trigger fires. Simplicity: No loss adjustment process, no adjuster negotiations, no dispute over quantum. For businesses where cash flow following a weather event is critical — a hotel during a washout season, a solar farm during prolonged cloud cover, a farmer during a drought — parametric cover provides operational certainty that indemnity policies cannot match.

Basis Risk — Understanding the Trade-Off

Basis Risk: The Fundamental Limitation

Basis risk is the gap between the parametric trigger and the insured's actual loss experience. It manifests in two directions:

Trigger Without Loss

The index fires — the insurer pays — but the insured has not actually suffered a significant loss from that event. The insured receives a windfall relative to their actual damage.

Loss Without Trigger

The insured suffers a real financial loss, but the index does not reach the trigger threshold. No payment is made, despite the actual loss. This is the more commercially significant direction of basis risk.

Basis risk is not a defect — it is the inherent trade-off that makes parametric cover possible. Accepting a degree of basis risk is what enables rapid payment, low transaction costs and policy simplicity. Good product design — selecting the right index type, the right monitoring station or satellite grid, and the right trigger calibration — minimises basis risk without eliminating it entirely. For buyers whose primary need is rapid liquidity (rather than full indemnity), residual basis risk is an acceptable cost.

Important: Parametric insurance is not intended to replace traditional indemnity insurance. For most large risks, the optimal structure combines parametric cover (for speed and liquidity) with a traditional indemnity policy (for full loss recovery). The two products address different needs and complement rather than duplicate each other.
Use Cases

Where Parametric Cover Is Most Effective

Agriculture

Rainfall deficit and excess rainfall are the most common agricultural parametric triggers in Turkey and globally. A rainfall index policy for an olive producer, for example, might trigger if cumulative rainfall at the nearest MGM (Turkish State Meteorological Service) weather station falls below a defined threshold during the growing season. TARSİM — Turkey's state-supported Agricultural Insurance Pool — administers index-based crop schemes for qualifying producers; private corporate parametric cover is available beyond the TARSİM framework for larger agri-businesses.

Renewable Energy

Solar and wind farm operators face revenue volatility from resource shortfall — prolonged cloud cover, low-wind periods. Parametric cover can be structured to pay when measured irradiance (for solar) or wind speed at hub height (for wind) falls below a production-correlated threshold over a defined period. This protects debt service coverage ratios in project-financed renewable energy assets.

Hospitality & Tourism

Hotels, resort operators and tourism businesses in Turkey's Aegean and Mediterranean coast face measurable weather-driven revenue risk — poor beach weather during peak season. A parametric product tied to rainfall days, temperature or sunshine hours at a nearby station can provide revenue support without requiring proof of occupancy loss.

Infrastructure & Earthquake

Earthquake parametric products — triggered by peak ground acceleration exceeding a defined threshold at a specified monitoring network station — are growing in Turkey, a seismically active country. They provide rapid capital for response and repair expenditure without waiting for damage assessment, and are being explored by municipalities, utilities and property companies as a complement to traditional earthquake insurance.

Frequently Asked Questions

How does parametric insurance differ from traditional insurance?
Traditional insurance pays based on an assessed loss — a claims adjuster evaluates actual damage. Parametric insurance pays a pre-agreed amount when a defined index reaches a specified threshold, regardless of whether the insured has suffered an actual loss. This eliminates loss adjustment and enables payment within days of a trigger event.
What is basis risk and why does it matter?
Basis risk is the gap between the parametric trigger and the insured's actual loss. The trigger may fire without a significant physical loss (over-payment), or a real loss may occur without activating the trigger (no payment). This is not a defect — it is the trade-off for speed and simplicity. Good product design minimises basis risk. For buyers whose priority is rapid liquidity, residual basis risk is an acceptable cost.
Can parametric insurance be combined with traditional indemnity cover?
Yes — and in practice this is often the optimal structure for large risks. Parametric cover provides rapid liquidity after a defined event, funding immediate operational response while the traditional indemnity claim is being adjusted. This layered approach is common in agricultural, energy and catastrophe risk programmes.
Who offers parametric insurance in Turkey?
State-supported crop parametric schemes are administered through TARSİM for qualifying agricultural producers. For corporate buyers — renewable energy producers, hotel chains, infrastructure companies — private parametric cover is available through the international reinsurance market, including Lloyd's of London, Swiss Re and Munich Re. A licensed reinsurance broker is required to access this international capacity.
What data sources are used to measure the trigger index?
The index must be based on objective, independently verifiable data: Turkish State Meteorological Service (MGM) for weather; USGS or EMSC for earthquakes; satellite-derived indices for agriculture. The independence and reliability of the data source is critical — both parties rely on it absolutely, so its integrity underpins the entire product.
