Financing evidence and diligence

Every disaster finance decision rests on evidence: risk models, loss data, exposure, forecast skill and evaluations of past instruments. Diligence asks whether that evidence is fit for the decision, who produced it and what it leaves out. This page sets out the evidence chain behind disaster risk finance, the questions diligence asks, the data sources with their licences, and who decides what counts.

01In brief

The short answer.

Disaster finance diligence is the review of the evidence behind a financing decision: risk models, exposure and loss data, forecast skill and evaluations of past instruments. It asks who produced the evidence and what it leaves out. Finance ministries, donors, risk managers and evaluation offices decide what counts.

04The question

Financing evidence and diligence: how the risk develops.

Independent reviewer information needs. The dossier below sets out how the risk develops, what is measured, where the data come from, how it is modelled and who decides.

Mechanism

Models drive price and triggers

Parametric triggers, insurance prices and layer sizes depend on catastrophe and forecast models. Their assumptions are often proprietary and hard for buyers to check.

Mechanism

Data gaps bias results

Exposure and loss data are thin in low-income countries. Models calibrated elsewhere may misjudge local vulnerability.

Mechanism

Independent review is rare

Buyers often rely on the seller's or broker's analysis. Independent review of models and terms protects buyers but adds cost and time.

Mechanism

Evaluation closes the loop

Evaluations of payouts, timeliness and outcomes show whether instruments worked. Without them, the same designs repeat regardless of results.

05Key terms

Terms used on this page.

Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.

TermDefinition
Due diligenceA structured review of evidence and terms before a financial commitment.
Open risk modelA risk model whose components and assumptions are published for inspection and reuse.
Risk Data LibraryAn open data standard for hazard, exposure, vulnerability and loss information.
06Indicators

What is measured, and how well.

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.

From sources to decisions.

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.

10Core questions

The questions experts ask.

  • What do independent reviewers need to know to assess a disaster finance arrangement?
  • Is the hazard and loss evidence credible, documented and reproducible?
  • Are plans for using funds clear, and are delivery channels in place?
  • Is the governance of decisions and funds transparent and accountable?
  • What uncertainties remain, and are they stated honestly?
11Mechanisms

What diligence looks at.

Reviewers, whether credit committees at development institutions, underwriters, investors or public audit bodies, typically examine several areas. Risk evidence covers hazard data, exposure, vulnerability and modelled losses, with their sources and uncertainty. Operational evidence covers plans, delivery systems and institutional capacity. Governance evidence covers legal authority, decision rules, safeguards and accountability. Financial evidence covers fiscal position, existing arrangements and how a new arrangement would fit.

Evidence quality matters more than volume. Reviewers look for documented methods, traceable sources, independent validation and clear statements of what is not known. Overstated certainty undermines trust; honest uncertainty allows reviewers to price or plan for it.

A disaster finance dossier, as GRA designs it, assembles such evidence as research for independent reviewers. It does not recommend a transaction, assess creditworthiness or certify readiness. Readiness is not approval: the decision remains with the reviewer and the competent authority.

12Methods and data

Methods and their limits.

Evidence

Evidence classes

Distinguishing observed data, modelled estimates and expert judgement.

Validation

Independent review

Review of models and data by parties not involved in producing them.

Lineage

Traceability

Recording sources, versions and transformations so evidence can be checked.

Limits: evidence can reduce uncertainty but not remove it, and some information reviewers want, such as future political responses, cannot be known.

14Questions

Questions and answers.

What should diligence check in a parametric product?
Whether the trigger tracks the losses that matter, the forecast or measurement skill behind it, the model assumptions, basis risk evidence and how payouts reach those affected.
What is the Risk Data Library?
An open data standard for hazard, exposure, vulnerability and loss data, developed to make risk data easier to share and compare.
Why do open models matter?
They let buyers, regulators and researchers inspect and test the assumptions behind prices and triggers instead of relying on one provider's view.
Is a dossier a recommendation to finance?
No. It is research evidence for independent reviewers. GRA does not recommend, arrange or approve any transaction.
Who prepares dossiers?
Dossiers open when editors, reviewers and terms are in place; they are prepared under GRA's editorial and integrity rules.
Can a dossier be corrected?
Yes. Corrections are logged with reasons on the platform's corrections page.
