What if… Worldwide earthquakes reach 17 to 19 magnitude 7.0 or higher in 2026

◇ Hypothetical scenario. What if… Worldwide earthquakes reach 17 to 19 magnitude 7.0 or higher in 2026? The analysis positions SSD, CAT and URI to benefit and PLMR, RNR and ALL under pressure; confidence low.

Hypothetical scenario — this analysis maps conditional exposure (“if this happens, who is exposed”). It is not graded against market prices unless the event occurs.

Analyzed 2026-09-14 — point-in-time, never revised. A hypothetical scenario is never graded.

Ranked exposures

  1. ▼ PLMR Palomar — impact -75 · confidence low · horizon immediate · 1st order
    Palomar concentrates on residential earthquake coverage, so a heavier event year drives claims and reinsurance costs above plan.
    Chain: elevated count of magnitude seven events globally → California and Pacific Northwest shaking damages insured homes → Palomar quake policies absorb direct claim severity → reinsurance renewal pricing rises on Palomar program
    What would break the call: The elevated event count lands outside California and Palomar reports catastrophe losses inside its stated retention.
  2. ▼ RNR RenaissanceRe — impact -74 · confidence medium · horizon immediate · 1st order
    Repeated major earthquakes increase RenaissanceRe's reinsurance losses, weakening its combined ratio and book value.
    Chain: more magnitude seven quakes worldwide in 2026 → cedent property treaties breach attachment points → RenaissanceRe pays property catastrophe recoveries → combined ratio and tangible book value fall
    What would break the call: Quakes strike sparsely insured regions and industry insured loss stays below annual catastrophe budgets.
  3. ▼ ALL Allstate — impact -73 · confidence medium · horizon immediate · 1st order
    Earthquakes increase Allstate's homeowners and commercial property claim payouts across insured American regions.
    Chain: heightened seismic activity includes United States events → homeowners and commercial property structures sustain damage → Allstate pays fire and collapse claims → catastrophe loss line rises above plan
    What would break the call: Earthquake exclusions hold and Allstate reports no material domestic quake catastrophe losses for the year.
  4. ▼ CB Chubb — impact -70 · confidence high · horizon quarters · 1st order
    Earthquakes increase Chubb's catastrophe claims across commercial property and high-value home policies in seismic zones.
    Chain: global quake frequency rises above trend → commercial and high value homes in seismic zones damaged → Chubb pays property and business interruption claims → catastrophe loss ratio widens for the year
    What would break the call: Chubb discloses limited quake aggregate and reports catastrophe losses inside its quarterly budget.
  5. ▼ TRV Travelers — impact -66 · confidence medium · horizon immediate · 1st order
    Earthquake destruction increases Travelers' commercial property claim costs across insured operations worldwide.
    Chain: more large magnitude events during 2026 → insured commercial buildings and inventory damaged → Travelers pays property and business interruption claims → catastrophe losses cut underwriting gain
    What would break the call: Travelers reports domestic quake exposure as immaterial and catastrophe losses stay driven by wind and hail.
  6. ▼ ACGL Arch Capital — impact -63 · confidence medium · horizon immediate · 1st order
    Higher earthquake frequency increases Arch Capital's property catastrophe reinsurance claims and loss ratios worldwide.
    Chain: clustered magnitude seven events worldwide → property catastrophe treaties trigger across regions → Arch reinsurance segment books quake losses → segment loss ratio and earnings decline
    What would break the call: Arch shows quake events falling below treaty attachment points and reports benign catastrophe experience.
  7. ▲ SSD Simpson Manufacturing — impact +62 · confidence low · horizon quarters · 2nd order
    Simpson sells seismic connectors and anchors, so retrofit and rebuild activity lifts unit volumes across quake exposed regions.
    Chain: frequent quakes raise seismic risk awareness → code enforcement and retrofit programs accelerate → builders specify more holdowns and anchors → Simpson North America unit volume rises
    What would break the call: Housing starts fall further and retrofit spending stays flat while Simpson volumes decline.
  8. ▼ EG Everest Group — impact -60 · confidence low · horizon immediate · 1st order
    Everest writes global property treaty reinsurance, so international quake losses hit underwriting income and force reserve strengthening.
    Chain: international quake losses hit cedent portfolios → Everest global property treaties respond → reinsurance segment absorbs catastrophe losses → underwriting income and book value decline
    What would break the call: Everest reports quake losses inside its catastrophe load while reserve development stays favorable.
  9. ▼ PGR Progressive — impact -60 · confidence low · horizon quarters · 3rd order
    Progressive records higher loss ratios from claims related to earthquake induced accidents.
    Chain: quakes damage roads and trigger debris → vehicle damage and accident frequency rise locally → Progressive auto and property claims increase → loss ratio moves modestly higher
    What would break the call: Progressive reports stable auto frequency and no catastrophe charge tied to seismic events.
  10. ▲ CAT Caterpillar — impact +58 · confidence medium · horizon quarters · 2nd order
    Earthquake reconstruction increases Caterpillar sales of replacement construction equipment and generators across damaged regions.
    Chain: quake damage destroys buildings and infrastructure → governments fund demolition and reconstruction programs → contractors order excavators and generators → Caterpillar machine and power sales rise
    What would break the call: Reconstruction funding stalls and Caterpillar dealer machine orders stay flat through 2026.
  11. ▲ URI United Rentals — impact +58 · confidence low · horizon weeks · 2nd order
    Rental demand increases for United Rentals as contractors need temporary power earthmoving machines and cleanup equipment.
    Chain: quakes create urgent cleanup and repair work → contractors need equipment faster than purchase cycles → United Rentals fleet utilization and rates rise → specialty and general rental revenue grows
    What would break the call: Damaged regions sit outside United Rentals branch footprint and utilization stays unchanged.
  12. ▼ AIG AIG — impact -57 · confidence medium · horizon immediate · 1st order
    Earthquake damage increases AIG's commercial property insurance losses on multinational clients' covered physical assets worldwide.
    Chain: quakes damage multinational client facilities → AIG global commercial property policies respond → catastrophe claims and business interruption payouts rise → North America and international underwriting income falls
    What would break the call: AIG cedes most quake aggregate to reinsurers and reports net catastrophe losses as immaterial.
  13. ▼ AXS Axis Capital — impact -56 · confidence medium · horizon immediate · 1st order
    Accumulating earthquake claims increase Axis Capital's reserves and catastrophe losses across international property insurance portfolios.
    Chain: international property portfolios absorb quake damage → Axis insurance and reinsurance lines pay claims → reserves strengthen for late reported losses → combined ratio deteriorates for the year
    What would break the call: Axis exits remaining property catastrophe reinsurance and reports minimal quake loss exposure.
  14. ▼ PCG PG&E — impact -50 · confidence low · horizon quarters · 2nd order
    PG&E utility infrastructure sustains damage leading to elevated repair costs and outages.
    Chain: California shaking damages towers pipelines and substations → PG&E funds emergency repairs and restoration → outage duration triggers regulatory scrutiny → repair capital and liability costs rise
