At the January 1, 2024, reinsurance renewal, the Guy Carpenter Global Rate on Line (ROL) Index increased by an estimated 5.4% year-on-year. Notable regional calculations include the US index increasing by 5.25% and Europe slightly higher at 7.6%. Guy Carpenter noted that outcomes were affected by regional loss activity, structure adjustments and ongoing scrutiny of pricing adequacy.

The Guy Carpenter ROL index is a measure of the change in dollars paid for coverage year on year on a consistent program base. The index reflects the pricing impact of a growing (or shrinking) exposure base, 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.
