Retrocession
The transfer of reinsurance risk from one reinsurer to another reinsurer, effectively reinsurance of reinsurance.
What It Is
Retrocession is the process by which a reinsurer cedes a portion of the risk it has assumed to another reinsurer, known as the retrocessionaire. It is essentially reinsurance of reinsurance. The original reinsurer becomes a retrocedent, transferring risk further along the chain to manage its own exposure, diversify its portfolio, or free up capacity.
Retrocession serves the same purposes for reinsurers that reinsurance serves for primary carriers: managing catastrophe exposure, reducing volatility, diversifying risk, and managing capital. A reinsurer that assumes $500M in catastrophe risk from multiple cedents might retrocede $200M to spread the exposure across additional balance sheets.
Retrocession creates longer chains of financial dependency. If a major catastrophe occurs, claims flow from the insured to the primary carrier, from the carrier to the reinsurer, and from the reinsurer to the retrocessionaire. If any link in the chain fails financially, the entities above it must absorb the shortfall. This chain risk was highlighted during the Lloyd's near-collapse in the early 1990s, when retrocession spirals amplified losses throughout the market.
Why It Matters for Brokers
Retrocession is largely invisible to brokers but affects market capacity and pricing. When retrocession capacity tightens (as it did after Hurricane Ian in 2022), reinsurers have less ability to absorb risk, which tightens their own treaty terms with primary carriers, which in turn raises prices for policyholders. Understanding this cascade helps brokers explain market-wide hardening to clients.
Real-World Example
A global reinsurer assumes $2B in catastrophe risk from 45 primary carriers worldwide. It retrocedes $800M through a catastrophe bond program and retrocession treaties with three other reinsurers. After a $4B industry catastrophe event, the reinsurer's gross loss is $180M. After retrocession recoveries of $72M, its net loss is $108M. The retrocession program prevented a loss that would have impaired the reinsurer's ability to renew treaties with its 45 cedents.
Common Mistakes
- 1Not recognizing that market-wide rate increases often originate in the retrocession market and cascade down through reinsurance to primary insurance.
- 2Assuming the financial chain ends with the reinsurer when retrocession creates additional dependencies that can amplify systemic risk.
