Willis Re, a specialised reinsurance broker, reports that two parametric risk transfer deals have recently drawn attention after confirming swift payouts to Jamaica.
Hurricane Melissa activated the country’s $150 million World Bank sovereign bond, which had notably defaulted after Hurricane Beryl the previous year.
At the same time, the Caribbean Catastrophe Risk Insurance Facility, the world’s largest parametric insurance program, is releasing $70.8 million to Jamaica, marking its largest claim ever, with the possibility of additional payments.
Willis Re highlights that the defining feature of parametric coverage is speed. Payouts are confirmed within days of a qualifying event, while traditional indemnity-based reinsurance claims can take months to finalise. In Jamaica’s case, Willis Re notes that this approach has provided certainty for the insured and ensured cash is available quickly to meet urgent needs.
The company believes parametric reinsurance has reached a new level of maturity. Originally tested in catastrophe bond markets to protect sovereigns and provide retrocession capacity, parametric solutions are now widely available to commercial insurers. Willis Re sees these structures as a regular part of reinsurance programmes globally, offering a practical option for companies seeking to manage peak catastrophe risk.
Unlike traditional indemnity contracts, parametric coverage pays a predetermined amount when specified event parameters are met, such as wind speeds, earthquake magnitudes, or rainfall levels. Willis Re points out that because payments are triggered by the event itself rather than losses, capital is released immediately, providing an essential liquidity buffer and reducing the financial friction typically seen after disasters.
Willis Re emphasises that parametric coverage can be integrated flexibly into any reinsurance programme. For example, an insurer facing hurricane exposure might use a parametric layer to protect its retention or fund reinstatement premiums following a major storm.
The company highlights that this approach does not replace conventional reinsurance but complements it, absorbing losses in a way that maintains capital stability and reinforces the insurer’s broader programme.
Willis Re also notes that parametric structures have evolved to address concerns about coverage gaps or “basis risk.” Modern contracts often feature sliding-scale payouts that vary based on storm intensity, proximity to urban centres, or other factors.
Some parametric programmes now combine event triggers with modelled portfolio losses, giving insurers a closer alignment with conventional coverage while maintaining many of the advantages of speed and certainty. Willis Re cautions that while these hybrid approaches can reduce pricing, they may introduce subjectivity into the calculations and slow the settlement process.
Willis Re further observes that parametric solutions are increasingly sophisticated, using advanced data such as satellite imagery to assess wildfire impact or in-situ sensors to measure seismic activity.
These innovations help ensure that payouts reflect the reality of the insured portfolio and improve confidence in the coverage. Willis Re concludes that Jamaica’s experience with Hurricane Melissa demonstrates the practical benefits of parametric reinsurance.
The instrument delivered exactly as intended, providing certainty and rapid liquidity, and highlights a broader shift in risk management.Willis Re believes parametric reinsurance is now a core tool for insurers and sovereigns, helping to manage climate-driven catastrophe risk and close the global protection gap while complementing traditional reinsurance.
