At the 1/1 reinsurance renewals, Guy Carpenter’s global rate-on-line index increased by an estimated 5.4% year-on-year.

Rate-on-line (RoL) for underwriting property catastrophe reinsurance business in Europe was up by 7.6% year-on-year at the 1 January 2024 reinsurance renewals, according to Guy Carpenter.


That rise was ahead of the US index, which was also up, increasing by 5.25% at 1/1, the reinsurance broker said.

Overall, the Guy Carpenter global rate-on-line index increased by an estimated 5.4% year-on-year (see chart below).

Guy Carpenter said the RoL index outcomes were affected by regional loss activity, structure adjustments and ongoing scrutiny of pricing adequacy.

The reinsurance broker’s RoL index is a measure of the change in dollars paid for coverage year-on-year on a consistent programme base.

The RoL index reflects the pricing impact of a growing (or shrinking) exposure base, the broker said.

The index also reflects evolving methods of measuring risk and changes in buying habits, as well as changes in market conditions.

Unlike risk-adjusted measurements, the index is not dependent on the model or method used to measure the amount of perceived risk in a program, which can vary widely, the broker noted.
