The insurance sector has borne some of the most significant financial impacts in history, particularly in the wake of natural disasters and unprecedented, catastrophic events. From hurricanes and earthquakes to unprecedented storms, these incidents have resulted in staggering insurance payouts that not only reflect the devastation caused but also highlight the evolving landscape of risk management and coverage.
As climate change continues to influence weather patterns and increase the frequency of extreme events, understanding these monumental insurance payments offers valuable insights into the industry's challenges and opportunities. In this article, we explore 10 of the largest insurance payments ever recorded, shedding light on the brokers most affected and the lessons learned from each event.
P.S. We are only including traditional insurance payouts in this list, rather than bailouts subsidised by national governments. Whilst not a traditional insurance claim, the U.S. government's bailout of AIG during the 2008 financial crisis - totalling an eyewatering US$81bn - was effectively an enormous insurance payment. For the purposes of this article, however, we are only including claims and payouts made through insurance companies. On with the list!
