Scenario guides / Natural disaster & climate shock
🌪️ Natural disaster & climate shock
Disasters are unusual among crises: they destroy real wealth in days, then generate years of spending to rebuild it. That two-phase rhythm — destruction, then reconstruction — is the key to understanding which assets suffer and which quietly benefit.
What history shows
Hurricane Katrina (2005) caused well over $100 billion in damage, knocked out a significant share of US Gulf oil and refining capacity — sending fuel prices sharply higher — and hammered property insurers with record claims. Yet within months, construction firms, building-material suppliers and engineering companies were working through a rebuilding boom.
The Tōhoku earthquake and Fukushima disaster (2011) showed how a local catastrophe ripples through global supply chains: the Nikkei fell over 16% in two trading days, factory shutdowns halted car and electronics production worldwide, and the nuclear sector was repriced globally — Germany announced a full nuclear exit within months, while uranium-linked assets fell for years.
The 2011 Thailand floods made the supply-chain point even more bluntly: a quarter of the world's hard-drive production went underwater, and global hard-drive prices roughly doubled within weeks. Disasters anywhere can reprice industries everywhere.
Assets that have tended to gain
- Construction, engineering & building materials — reconstruction is a multi-year, government-backed spending wave.
- Agricultural commodities — droughts, floods and frosts destroy supply while demand stays fixed; food prices respond fast.
- Products with disrupted supply — whatever the affected region produced becomes scarce, from oil (Katrina) to semiconductors (Thailand).
- Consumer staples — emergency demand and inelastic consumption make them resilient.
Assets that have tended to suffer
- Property in the affected region — the direct loss, compounded by rising insurance costs and, increasingly, climate-driven uninsurability in exposed areas.
- Insurers — catastrophe claims hit immediately (though premiums, and profits, often rise in the following years — the "payback" cycle).
- Utilities with damaged infrastructure — repair costs and liability risk; Tokyo Electric Power lost most of its market value after Fukushima.
- Tourism and local services — visitors stay away long after the waters recede.
Wildcards and caveats
Single disasters are usually local market events with global ripples, not global bear markets — world equity indices barely register most hurricanes. The scenario becomes systemic when disasters are large, repeated or climate-driven, feeding into insurance pricing, food costs and inflation. That is why the dashboard treats disaster severity as a dial rather than a switch.
