<p>Bot: Creating new article from JSON</p> <p><b>New page</b></p><div>⚠️ &#039;&#039;&#039;Catastrophe risk&#039;&#039;&#039; is the exposure an [[Definition:Insurance carrier | insurer]] or [[Definition:Reinsurance | reinsurer]] carries to low-frequency, high-severity events — hurricanes, earthquakes, pandemics, large-scale cyber attacks — capable of generating correlated [[Definition:Claim | claims]] that far exceed what normal loss experience would predict. In the insurance context, it is distinguished from attritional or frequency risk by the sheer concentration of potential losses in both time and geography, making it one of the most capital-intensive perils to underwrite.<br /> <br /> 🔄 Managing catastrophe risk involves a layered strategy. [[Definition:Underwriting | Underwriters]] control accumulation by setting per-event and per-zone limits, guided by outputs from [[Definition:Catastrophe model | catastrophe models]]. Beyond internal controls, carriers transfer portions of catastrophe risk to [[Definition:Reinsurance | reinsurers]] through [[Definition:Excess of loss reinsurance | excess-of-loss treaties]] and to [[Definition:Capital markets | capital markets]] through instruments like [[Definition:Catastrophe bond | catastrophe bonds]] and [[Definition:Industry loss warranty (ILW) | industry loss warranties]]. [[Definition:Exposure management | Exposure management]] teams continuously monitor portfolio aggregation, stress-testing against historical and hypothetical scenarios to ensure that a single event cannot threaten the company&#039;s [[Definition:Solvency | solvency]].<br /> <br /> 🏛️ Regulators worldwide treat catastrophe risk as a pillar of prudential oversight. Frameworks such as [[Definition:Solvency II | Solvency II]] in Europe and [[Definition:Risk-based capital (RBC) | risk-based capital]] standards in the United States require insurers to hold dedicated capital buffers against extreme event scenarios. Rating agencies, meanwhile, evaluate an insurer&#039;s catastrophe risk appetite and mitigation strategy as central factors in assigning financial strength ratings. As [[Definition:Climate change | climate change]] intensifies the frequency and severity of weather-related disasters, the industry faces growing pressure to refine its understanding of catastrophe risk — recalibrating models, repricing [[Definition:Premium | premiums]], and innovating new transfer mechanisms to keep the market sustainable.<br /> <br /> &#039;&#039;&#039;Related concepts&#039;&#039;&#039;<br /> {{Div col|colwidth=20em}}<br /> * [[Definition:Catastrophe loss]]<br /> * [[Definition:Catastrophe model]]<br /> * [[Definition:Reinsurance]]<br /> * [[Definition:Catastrophe bond]]<br /> * [[Definition:Exposure management]]<br /> * [[Definition:Probable maximum loss (PML)]]<br /> {{Div col end}}</div>
