Parametric insurance offers new way to fight climate risks
Descartes Underwriting is positioning parametric insurance as a solution to the gaps left by traditional coverage as climate-related risks become more difficult to assess. This method delivers payouts based on predefined conditions—such as specific weather events—rather than requiring damage verification, a process that can drag on for months under conventional policies. Ben Qin, Descartes’ head of North Asia and Australia, emphasizes that parametric insurance targets risks too complex for traditional models to handle effectively.
Australia presents a key market for this approach, where insurers have struggled to cover hazards like cyclones, bushfires, and floods. Descartes has already deployed parametric products in the region, including a frost insurance offering launched in 2022. Originally designed for French vineyards, the policy was adapted for Australian farms, evaluating individual paddocks while accounting for risk-reduction measures such as frost fences. Farmers who implement these protections qualify for lower premiums, reflecting their reduced vulnerability.
Australia’s agricultural sector has long faced underinsurance due to limited market capacity. The surge in input costs, fertilizers and chemicals have doubled over recent years, has further weakened the viability of self-insurance. Parametric contracts allow growers to establish clear risk thresholds, such as tolerance levels for a one-in-10-year or one-in-50-year event, and transfer excess risk beyond those limits.
How Local Weather Data Drives Payouts
Adapting products from France to Australia’s climate requires careful calibration. Qin highlights that while the fundamental challenges remain consistent, local data, particularly from the Bureau of Meteorology (BOM)—is essential. The BOM provides historical weather records used for underwriting and serves as an impartial authority to resolve disputes over payout triggers. For flood coverage, Descartes links payouts to nearby BOM gauges, simplifying verification for businesses.
Traditional insurers have reduced or withdrawn coverage for certain perils, creating gaps that parametric insurance seeks to address. Following the devastating 2019, 20 bushfire season, many insurers either excluded fire risks entirely or applied blanket restrictions. Parametric contracts offer an alternative where conventional models have failed to keep pace. Qin anticipates similar market adjustments for floods, as reinsurance capacity continues to shrink under repeated catastrophic losses.
Currently, Descartes focuses on single-peril policies, such as cyclones, floods, or hail, but plans to expand into bundled coverage. The industry’s shift toward parametric solutions reflects broader pressures: reinsurance pools are contracting, and insurers are tightening scrutiny on secondary perils. Qin stresses that scaling parametric insurance depends on educating clients about risk thresholds and the limitations of self-insurance.
Limitations of Parametric Coverage in Climate Risks
Parametric insurance is not a universal fix. It performs best for well-defined risks where data is reliable. Qin acknowledges that certain climate-related threats, particularly secondary effects, remain difficult to model. For now, the focus remains on addressing immediate coverage shortfalls where traditional insurance has withdrawn.
The effectiveness of parametric insurance depends on two critical factors: precise data and client understanding. Farmers, asset owners, and lenders must grasp their risk exposure and how these contracts integrate into broader resilience plans. Qin notes that while the sector is still evolving, the financial stakes, rising costs and heightened exposure, are driving demand for alternative solutions.
Descartes is part of a growing movement within the insurance industry exploring parametric models, especially for floods and wildfires. The critical question is whether the market can expand quickly enough to meet rising demand before traditional coverage collapses further.
Beyond Agriculture: Renewables Turn to Parametric Insurance
Local governments and businesses in high-risk zones are increasingly turning to parametric solutions. In the renewable energy sector, where solar and wind farm operators face exposure to extreme weather without adequate traditional coverage, parametric models offer a viable alternative.
Qin concludes that while parametric insurance is not a panacea, it offers a practical way forward for sectors struggling to secure protection against unmodelled perils.
