Weekly Resilience Briefing — Week of 2026-10-29

Week ending

The resilience economy this week was shaped by three converging forces: a softening but disciplined ILS and catastrophe bond market continuing to attract capital despite more favorable terms ahead; a wave of Q3 insurer earnings revealing sustained pressure from casualty reserve charges and catastrophe losses; and a pair of major policy frameworks — the EU Climate Resilience Framework and Pennsylvania's flood disclosure law — signaling that governments are moving to formalize climate risk into legal and financial structures. Underlying all three threads is the question of model reliability, as six consecutive years of

00 billion-plus cat losses are forcing a reckoning with how risk is measured and priced.
