Aon’s reinsurance arm remains the largest reinsurance intermediary by some distance in a survey conducted by re-Insurance that uses a combination of publicly available information and market intelligence.

In re-Insurance’s Sunday Monte Carlo edition, we reveal that Aon Reinsurance Solutions - which rebranded from Aon Benfield earlier this year - earned revenues of $1.43bn last year, some 20 percent higher than number two incumbent Guy Carpenter.

In third place, after a strong 2017, was Willis Re with estimated revenues in the region of $860mn. Re-Insurance calculate this was a significant leap on circa $790mn the year before.

Strong growth was also notable among two fast-growing mid-tier intermediaries that are both poised to celebrate significant anniversaries.

Capsicum Re - which celebrates its fifth birthday later this year - saw its 2017 revenues increase by 50 percent to £48mn from the year earlier, measured in sterling.

TigerRisk, which celebrates its ten year anniversary this year, also enjoyed a strong 2017 with revenues climbing to an estimated $90mn. In addition to its traditional Florida specialism, the Rod Fox-led firm advised on a number of niche significant placements last year.

Indeed, 2017 was a strong year for mont intermediaries who capitalised on the increased demand for both longer-tail placements, adverse development covers and cat treaties - especially in the wake of the cat events in the second half of 2017.

At JLT Re overall revenues were up 11 percent to £217.1mn ($280mn), including 4 percent organic growth.
