No NOAA Large-Disaster Data to Hurt Insurers’ Grasp of Secondary Perils, Says AM Best

By | May 20, 2025

Insurance industry financial strength rating agency AM Best said today that a decision to stop updating a National Oceanic and Atmospheric Administration disaster database could be detrimental to insurers and may require the rethinking of some products.

About two weeks ago NOAA announced it will “retire” a free, public database of climate and weather disasters that caused at least $1 billion in damage, “with no updates beyond calendar year 2024.” Past reports from 1980-2024 will be archived.

AM Best said the move could affect insurers’ ability to track losses from so-called secondary perils such as wildfires, floods, and severe convective storms. This group of perils is an increasing cause of catastrophe losses, especially in North America.

“Having a common and agreed-upon data source would help insurers trend these losses in their modeling and use the data for pricing, reinsurance and risk management, as well as help assess the gap between insured losses and economic losses and see how insurance can work to minimize the gap,” said Sridhar Manyem, AM Best’s senior director, industry research and analytics, in a statement.

AM Best pointed out that the end of the service by NOAA comes following a year of 27 weather events with at least $1 billion in damages. Manyem said if more databases disappeared, “parametric triggers within catastrophe bonds, which depend on measurement by NOAA, may need to be redesigned.”

“While some other countries have governmental agencies that track similar data, private companies may have to step in to fill the void and it could take some years to build credibility and trust among market participants,” he added.
