Guy Carpenter

Founded in 1922, Guy Carpenter is a global reinsurance intermediary and risk advisory business within Marsh McLennan. It works primarily with insurers, reinsurers, governments and insurance-related investors to structure, negotiate and place risk-transfer programs.

Its offering combines reinsurance broking with actuarial, catastrophe and capital modelling, portfolio management, rating-agency advisory and event-response capabilities. Through its capital and advisory activities, it also supports catastrophe bonds, insurance-linked securities, capital raising and insurance-sector M&A.

Guy Carpenter is especially strong where quantitative risk analysis and capital markets expertise intersect: natural-catastrophe risk, structured reinsurance, parametric coverage, retrocession and capital optimisation. Its analytics platform includes proprietary catastrophe and capital-modelling tools alongside vendor-model analysis.
