<p><b>New page</b></p><div>🌀 '''Tropical cyclone''' is a large-scale rotating storm system that forms over warm ocean waters and poses one of the most significant [[Definition:Natural catastrophe | natural catastrophe]] exposures facing the global insurance industry. Known as hurricanes in the Atlantic and eastern Pacific, typhoons in the western Pacific, and cyclones in the Indian Ocean and South Pacific, these storms generate extreme wind, [[Definition:Storm surge | storm surge]], and rainfall that can cause devastating insured losses across personal, commercial, and specialty lines. For [[Definition:Insurance carrier | insurers]] and [[Definition:Reinsurer | reinsurers]], tropical cyclones represent a defining peril — shaping [[Definition:Catastrophe modeling | catastrophe models]], [[Definition:Reinsurance | reinsurance]] purchasing strategies, and [[Definition:Capital requirement | capital requirements]] worldwide.<br />
<br />
🌊 The insurance mechanism for addressing tropical cyclone risk operates across multiple layers. [[Definition:Primary insurer | Primary insurers]] write [[Definition:Homeowners insurance | homeowners]], [[Definition:Commercial property insurance | commercial property]], [[Definition:Business interruption insurance | business interruption]], and [[Definition:Automobile insurance | auto]] policies that respond to wind, water, and related damage — though the precise scope depends on policy language, as [[Definition:Flood insurance | flood]] and [[Definition:Wind coverage | wind]] perils are sometimes separated or excluded. Insurers manage their aggregate cyclone exposure through [[Definition:Catastrophe reinsurance | catastrophe reinsurance]] programs, [[Definition:Catastrophe bond (cat bond) | catastrophe bonds]], and [[Definition:Industry loss warranty (ILW) | industry loss warranties]]. [[Definition:Catastrophe model | Catastrophe models]] from vendors such as [[Definition:Moody's RMS | Moody's RMS]], [[Definition:Verisk | Verisk]], and [[Definition:CoreLogic | CoreLogic]] simulate thousands of possible storm tracks, intensities, and landfall scenarios to estimate [[Definition:Probable maximum loss (PML) | probable maximum losses]] and generate [[Definition:Exceedance probability curve | exceedance probability curves]]. Regulatory regimes reflect the peril's significance: the [[Definition:Florida Hurricane Catastrophe Fund (FHCF) | Florida Hurricane Catastrophe Fund]], Japan's earthquake and windstorm [[Definition:Insurance pool | pools]], and [[Definition:Solvency II | Solvency II]] natural catastrophe sub-modules all incorporate tropical cyclone risk explicitly.<br />
<br />
📈 Few perils have shaped the modern (re)insurance market as profoundly as tropical cyclones. Landmark events — Hurricane Andrew in 1992, which exposed catastrophic reserve inadequacy and spurred the creation of the modern [[Definition:Insurance-linked securities (ILS) | ILS]] market; Typhoon Jebi in 2018, which revealed underestimated secondary peril losses in Japan; and Hurricane Katrina in 2005, which remains one of the costliest insured events in history — have repeatedly forced structural change in how the industry models, prices, and capitalizes against wind risk. As [[Definition:Climate change | climate change]] research suggests evolving cyclone frequency, intensity, and geographic reach, insurers face growing pressure to reassess long-held assumptions. [[Definition:Rate adequacy | Rate adequacy]], [[Definition:Concentration risk | concentration management]], and the availability of affordable coverage in cyclone-prone coastal regions remain among the most consequential strategic and public-policy challenges the industry confronts.<br />
