<p>Bot: Creating new article from JSON</p> <p><b>New page</b></p><div>🌀 &#039;&#039;&#039;Catastrophe reinsurance&#039;&#039;&#039; is [[Definition:Reinsurance | reinsurance]] purchased by [[Definition:Insurance carrier | primary insurers]] specifically to protect against the accumulation of losses arising from catastrophic events — natural disasters, large-scale industrial accidents, terrorism, or other occurrences that generate a surge of [[Definition:Claim | claims]] across many [[Definition:Policy | policies]] simultaneously. It stands apart from other reinsurance lines because the underlying risk is characterized by extreme severity and spatial correlation: a single hurricane can trigger thousands of property claims across an entire region in a matter of hours. The most common form is [[Definition:Catastrophe excess of loss reinsurance | catastrophe excess of loss]], though [[Definition:Aggregate excess of loss | aggregate covers]], [[Definition:Industry loss warranty (ILW) | industry loss warranties]], and [[Definition:Catastrophe bond | catastrophe bonds]] all serve related purposes.<br /> <br /> 🔄 Placement typically occurs during organized renewal seasons — January 1 being the largest — through [[Definition:Reinsurance broker | reinsurance brokers]] who assemble panels of reinsurers willing to participate on each layer of a program. [[Definition:Catastrophe model | Catastrophe models]] are central to the negotiation process: cedents and reinsurers rely on modeled loss distributions to agree on [[Definition:Attachment point | attachment points]], limits, pricing, and structural features like [[Definition:Reinstatement | reinstatements]] and event definitions. In recent years, [[Definition:Insurance-linked securities (ILS) | alternative capital]] from pension funds, sovereign wealth funds, and specialized ILS managers has supplemented traditional reinsurer capacity, creating a more diverse but also more complex marketplace. Contractual language matters enormously — the [[Definition:Hours clause | hours clause]], territorial scope, and peril definitions all determine whether and how a loss event triggers a recovery.<br /> <br /> 🏛️ Without catastrophe reinsurance, few primary insurers could afford to write meaningful volumes of [[Definition:Property insurance | property]] or [[Definition:Casualty insurance | casualty]] business in regions exposed to natural disasters. It functions as the shock absorber of the insurance ecosystem, preventing individual company failures from cascading into market-wide crises. Regulators recognize this role and often require insurers to demonstrate adequate catastrophe reinsurance coverage as a condition of licensure or [[Definition:Risk-based capital (RBC) | capital adequacy]] compliance. The health of the catastrophe reinsurance market — its capacity, pricing trajectory, and willingness to cover emerging perils like [[Definition:Wildfire risk | wildfire]] and severe convective storms — is closely watched as an indicator of the broader insurance industry&#039;s ability to fulfill its societal promise of financial protection after disaster.<br /> <br /> &#039;&#039;&#039;Related concepts&#039;&#039;&#039;<br /> {{Div col|colwidth=20em}}<br /> * [[Definition:Catastrophe excess of loss reinsurance]]<br /> * [[Definition:Catastrophe bond]]<br /> * [[Definition:Industry loss warranty (ILW)]]<br /> * [[Definition:Retrocession]]<br /> * [[Definition:Catastrophe model]]<br /> * [[Definition:Insurance-linked securities (ILS)]]<br /> {{Div col end}}</div>
