🔗 '''Reinsurance dependency''' describes the degree to which an [[Definition:Insurance carrier | insurance carrier]] relies on [[Definition:Reinsurance | reinsurance]] to underwrite business, maintain [[Definition:Solvency | solvency]] margins, and stabilize financial results. While virtually every insurer uses reinsurance as a risk management tool, dependency becomes a concern when a company's ability to continue writing [[Definition:Premium | premiums]], pay [[Definition:Claims | claims]], or meet [[Definition:Capital requirement | capital requirements]] would be materially compromised if reinsurance capacity contracted, became significantly more expensive, or if key [[Definition:Reinsurer | reinsurer]] relationships were severed.

📊 Several indicators signal elevated dependency. A high ratio of [[Definition:Ceded premium | ceded premiums]] to [[Definition:Gross written premium (GWP) | gross written premiums]], large [[Definition:Reinsurance recoverable | reinsurance recoverables]] relative to [[Definition:Surplus | surplus]], and concentration of cessions with a small number of reinsurers all raise flags. [[Definition:Rating agency | Rating agencies]] like A.M. Best explicitly assess reinsurance dependency in their credit analysis, examining whether a carrier could absorb a sudden loss of reinsurance support without falling below minimum regulatory capital. Companies that operate as [[Definition:Fronting insurer | fronting carriers]] — writing policies primarily to pass risk through to [[Definition:Managing general agent (MGA) | MGAs]] or [[Definition:Captive insurance company | captives]] via reinsurance — often exhibit structural dependency by design, though this is mitigated by [[Definition:Collateral | collateral]] requirements and strict [[Definition:Delegated underwriting authority (DUA) | delegated authority]] controls.

🌊 The practical dangers of excessive reinsurance dependency tend to surface during hard market cycles or after major [[Definition:Catastrophe loss | catastrophe events]], when reinsurers tighten terms, raise [[Definition:Reinsurance attachment point | attachment points]], and reduce available capacity. Carriers that depend heavily on reinsurance may be forced to shrink their book, raise [[Definition:Premium | pricing]] sharply, or exit lines of business entirely — disruptions that ripple out to [[Definition:Policyholder | policyholders]] and distribution partners. Regulators monitor this dynamic closely; some jurisdictions impose [[Definition:Net retention | minimum retention]] requirements to ensure insurers maintain genuine skin in the game. For strategic planning, understanding and managing reinsurance dependency is essential — it influences how much [[Definition:Underwriting risk | underwriting risk]] a carrier can absorb independently and how vulnerable it is to shifts in the global reinsurance market.
