Guy Carpenter (Marsh McLennan)
A reinsurance broker publishing market analyses and the Global Property Catastrophe Rate-on-Line index, the reference measure of catastrophe reinsurance pricing over time. Also covers renewal conditions and capacity. The only serious public series on reinsurance pricing.
An index built from the broker's catastrophe placement flow, relating premium to covered limit (rate on line) and its evolution. Representativeness depends on the broker's portfolio; the index measures a relative price trend rather than an absolute market level.
Use to document the catastrophe reinsurance price cycle, hardening or softening, over the long run. An authoritative input for reinsurance-market articles.
