📋 '''Inward reinsurance''' describes the business that a [[Definition:Reinsurer | reinsurer]] accepts from [[Definition:Ceding company | ceding companies]] — the primary [[Definition:Insurance carrier | insurers]] that transfer portions of their risk portfolios to reduce their own exposure. In reinsurance accounting and market parlance, the distinction between "inward" and "[[Definition:Outward reinsurance | outward]]" is fundamental: inward reinsurance is the perspective of the entity assuming risk, while outward reinsurance is the perspective of the entity ceding it. For a company like [[Definition:Swiss Re | Swiss Re]], [[Definition:Munich Re | Munich Re]], or a [[Definition:Lloyd's syndicate | Lloyd's syndicate]], inward reinsurance constitutes the core revenue-generating activity — it is the risk they take on, the [[Definition:Premium | premiums]] they earn, and the [[Definition:Claim | claims]] they pay.

⚙️ Operationally, inward reinsurance flows into a reinsurer's book through several channels. [[Definition:Treaty reinsurance | Treaty arrangements]] deliver a steady, portfolio-level intake of business under standing agreements that automatically cede defined portions of a primary insurer's book — whether on a [[Definition:Quota share | quota share]], [[Definition:Surplus treaty | surplus]], or [[Definition:Excess of loss reinsurance | excess of loss]] basis. [[Definition:Facultative reinsurance | Facultative placements]], by contrast, involve the individual assessment and acceptance of single risks or specific policies. Reinsurers evaluate inward business using actuarial models, historical [[Definition:Loss experience | loss experience]], and catastrophe modeling tools, pricing each treaty or facultative risk to achieve a target [[Definition:Combined ratio | combined ratio]] and return on [[Definition:Allocated capital | allocated capital]]. Under [[Definition:IFRS 17 | IFRS 17]], the accounting treatment of inward reinsurance contracts held by the assuming entity follows the general measurement model or the premium allocation approach, requiring careful classification that differs from the treatment under [[Definition:US GAAP | US GAAP]] or local statutory frameworks in markets like Japan or China.

💡 Understanding inward reinsurance is essential because it determines the financial health and strategic direction of the global reinsurance market. The volume, quality, and pricing of inward business directly shape a reinsurer's [[Definition:Underwriting profit | underwriting profit]], [[Definition:Reserve adequacy | reserve adequacy]], and exposure to [[Definition:Catastrophe risk | catastrophe accumulations]]. When reinsurance market conditions harden — as they do following major loss events or shifts in [[Definition:Retrocession | retrocession]] capacity — reinsurers gain leverage to be more selective about the inward business they accept, demanding higher rates, tighter terms, and improved [[Definition:Loss ratio | loss ratios]]. Conversely, in soft markets, competitive pressure can lead reinsurers to expand their inward books at thinner margins. Monitoring the composition and trend of inward reinsurance premiums is therefore a key indicator that [[Definition:Rating agency | rating agencies]], regulators, and investors use to assess a reinsurer's risk appetite and long-term viability.
