The Global Risks Alliance (GRA)
Insurance moves part of disaster cost from governments and households to insurers and capital markets. Sovereign parametric policies pay governments quickly; regional pools spread risk across countries; national schemes cover homes, farms and businesses, often with public support. This page sets out how these arrangements work, where basis risk and affordability limit them, the data behind them and who decides.
GRA · In development · service level R0
Sovereign insurance is cover bought by governments, often parametric, that pays quickly after defined disasters. Regional risk pools such as CCRIF SPC let countries share capital costs, and national schemes cover households and farmers. Finance and agriculture ministries, pool boards and supervisors hold the decisions.

Pools and insurance readiness. The dossier below sets out how the risk develops, what is measured, where the data come from, how it is modelled and who decides.
Payouts based on measured wind speed, rainfall or modelled loss arrive in days without loss adjustment. The trade-off is basis risk: the payout may not match the actual loss.
Countries in a pool rarely suffer major events in the same year. Pooling lowers capital needs and premiums compared with each country buying alone.
Reaching households and smallholders requires distribution through banks, cooperatives, mobile operators or social programmes, and premiums people can afford.
Subsidies raise take-up but can weaken incentives to reduce risk. Design choices decide who benefits and at what fiscal cost.
Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.
| Term | Definition |
|---|---|
| Basis risk | The difference between a parametric payout and the actual loss suffered. |
| Regional risk pool | A scheme through which several countries buy catastrophe cover together. |
| Index insurance | Insurance whose payout depends on an index, such as rainfall or area yield, rather than individual losses. |
Each indicator carries its unit, its cadence, the kind of source behind it and the evidence label a value would carry. No values are shown: a programme supplies them under its own authority.
| Indicator | Unit | Cadence | Source type | Label |
|---|---|---|---|---|
| Sovereign parametric cover purchased | currency of limit | annual | Pool records | OFFICIAL |
| Payouts by regional risk pools | currency and count | per event | Pool annual reports | OFFICIAL |
| Time from event to payout | days | per payout | Pool records | OBSERVED |
| Basis risk events | count of events with loss but no payout, or the reverse | per review | Evaluations | ESTIMATED |
| Agricultural insurance take-up | share of farmers | annual | Programme and survey data | REPORTED |
| Premium subsidy cost | currency per year | annual | Budget records | OFFICIAL |
The topic as a computational graph: named sources feed the methods, an evidence review gates the outputs, and the decisions stay with the authorities that hold them.

Disaster Risk Finance prepares evidence. The decisions below are taken by the authorities named, under their own rules, and never by the platform.
| Who decides | The question | Evidence this page serves |
|---|---|---|
| Finance ministries | Whether to buy sovereign cover and how much | Pool terms, basis risk evidence and cost comparisons |
| Pool boards and risk managers | How to design triggers and price cover | Model results and payout history |
| Agriculture ministries | Whether to subsidise farm insurance and how | Take-up, cost and evaluation evidence |
| Insurance supervisors | Whether index products are fairly designed and sold | Product review and complaint data |
Insurance works best for risks that are independent, measurable and affordable. Disasters challenge all three: losses are correlated across policyholders, data can be poor, and premiums can be unaffordable for those most exposed. Pools address correlation by combining risks from different regions or perils, which reduces the capital needed per participant, and they can lower costs through shared administration and access to reinsurance markets.
Parametric insurance pays an agreed amount when a measured index, such as wind speed, rainfall or earthquake intensity, crosses a threshold, rather than after a loss assessment. This can make funds available quickly, but it introduces basis risk: the index may not reflect actual losses, so a damaging event may produce no claim payment, or a payment may exceed need. Careful index design and communication are essential.
Readiness means more than buying cover. It includes knowing the risk, having a plan for using funds, clear authority to receive and spend them, and data and systems to monitor triggers.
Catastrophe models and actuarial analysis underpin pricing; model uncertainty is large for rare events.
Comparing index outcomes with historical losses to measure basis risk.
Reviewing how pools and insurance performed after events.
Limits: historical loss data for validating indices are often short, and the long-term performance of pools under changing hazards is uncertain.
The current service level is R0: information and enquiries. An enquiry receives a reference and names the next step; applications, payments, compute allocations and registrations open only when their team, terms and review capacity exist.
