For brokers, the old renewal playbook is starting to look outdated. Historical loss runs still matter, but they are no longer enough on their own when insurers and reinsurers are trying to price risks shaped by climate change, urban growth in exposed areas and rising catastrophe volatility. Across the market, more large insurers, reinsurers and brokers using climate data are shifting towards a more forward-looking view of risk, rather than relying mainly on retrospective loss histories. For brokers, that changes the submission task: a clean recent claims record may still help, but it may not be enough if the underlying exposure is moving faster than the data in the loss run.
