Insurance can already price physical climate risk. The rest of finance cannot read it. That is the translation gap.
“Under a 2.5 °C pathway, extreme weather events will increase.”
“1-in-100 chance of a $5bn loss in 2030. $7.5bn in 2040.”
The Rosetta Initiative is a platform, not a product.
Insurance, catastrophe modelling and actuarial science already price physical climate risk with real precision, period by period, at defined return periods. Mainstream finance cannot read that pricing. Physical risk is modelled as a distant scenario rather than a forward price curve, so it sits in a timezone where any reasonable discount rate washes it away, and capital arrives late, or not at all, in the places that need it most.
Serious work to close that gap is already under way: across insurers and reinsurers, catastrophe modelling and actuarial science, index, data and analytics providers, banks, asset managers and asset owners, supervisors and central banks, multilateral and development finance, and the communities carrying the risk. It is scattered, unmapped and short of critical mass.
The Rosetta Initiative exists to map that work, identify the gaps in it, and bring it together under an agreed common action framework, so that it becomes coherent, comparable and interoperable. We do not build analytical tools or data products, we do not duplicate what others are already doing well, and we are not a competing standard. We mobilise the market to close the translation gap.
Convenings are invite-only and held under the Chatham House rule.
