Open catastrophe reinsurance marketplace
Cedants, mutuals, public agencies, model developers, and capital providers could coordinate around open catastrophe models and standardized exposure files to price and place reinsurance layers more transparently.
Thesis
The concept shifts some reinsurance power from closed model and broker workflows toward a federated market where risk assumptions, exposure transformations, and loss outputs are easier for participants to inspect and challenge.
Bitcoin / decentralization role
Bitcoin is not central. Decentralization matters through open models, interoperable data standards, multiple capital providers, and marketplace governance that prevents a single reinsurer or model vendor from owning the full placement workflow.
Coordination mechanism
Cedants publish standardized exposure and policy data, model providers run comparable catastrophe models, brokers or marketplaces solicit capital bids, and reinsurers or ILS investors quote layers against auditable model outputs.
Verification / trust model
Cheating is constrained by exposure-data audits, model versioning, reproducible loss runs, independent model validation, contractual reporting, and post-event loss reconciliation. The model remains weak where exposure data is incomplete or incentives favor optimistic assumptions.
Failure modes
- • Open models can still be wrong or under-calibrated for local hazards.
- • Cedants may disclose incomplete exposure data or choose favorable model assumptions.
- • Large reinsurers and brokers may resist open placement workflows that weaken proprietary data and relationship advantages.
Adoption path
- • Begin with public-sector, mutual, or smaller cedant use cases where transparency is more valuable than proprietary placement advantage.
- • Use Oasis-format loss modelling and documented exposure standards to produce comparable catastrophe loss files.
- • Add reinsurance or ILS capital only after model governance, exposure audits, and dispute procedures are accepted by participants.
Decentralization fit
72.0/10
Open models and federated placement can decentralize risk analysis and capital matching while retaining accountable legal contracts.
Coordination credibility
61.0/10
The actors already exist in reinsurance markets, and Oasis provides credible open modelling infrastructure, but commercial adoption requires trust in data, models, and governance.
Implementation feasibility
54.0/10
Open catastrophe modelling is available, but production placement still requires exposure audits, legal contracts, capital commitments, broker workflows, and claims settlement processes.
Incumbent pressure
45.0/10
The concept can pressure opacity in catastrophe modelling and placement, but Arch's capital, relationships, and underwriting reputation remain strong defenses.
