Superstorm Sandy will likely become the third-costliest hurricane in U.S. insurance history, but when examining historical storms using today’s dollars and exposures, Sandy would fall to the 12th costliest storm, says the Insurance Information Institute.
In a presentation posted on I.I.I.’s website, initially given at Midwestern Actuarial Forum in Chicago today, I.I.I. Chief Economist Steve Weisbart projected Sandy insured losses to hit $20 billion, based on estimates of catastrophe-modeling firms and reported losses as of Jan. 12. That would place Sandy behind 1992’s Hurricane Andrew ($25.6 billion in insured losses) and ahead of 2008’s Hurricane Ike ($13.4 billion). All of those storms are dwarfed by 2005’s Katrina ($48.8 billion).
However, even mighty Katrina would be a middle-of-the-pack hurricane if some storms from the past occurred today. A 1926 hurricane that struck Miami, for example, would cause $125 billion in insured losses today. Another storm that struck mid-Florida in 1928 would cause $65 billion in insured losses. Factoring in these storms from the past, Katrina would fall to the sixth-costliest hurricane -- tied with a 1915 storm that struck Galveston, Texas and just ahead of the 1938 Long Island Express that struck parts of New England.
But with the lack of exposures back then compared to those that exist today, none of those destructive storms of the past crack the actual list of top-12 costliest storms. Instead, the current list features 10 storms that have occurred from 2004 and later. The only two not from that time period are Andrew and 1989's Hurricane Hugo ($7.8 billion in insured losses).
After the top four of Katrina, Andrew, Sandy and Ike, the list shows 2005’s Wilma ($11.1 billion in insured losses), 2004’s Charley ($9.2 billion), 2004’s Ivan ($8.7 billion), Hugo, 2005’s Rita ($6.7 billion), 2004’s Frances ($5.6 billion), 2004’s Jeanne ($5.6 billion) and 2011’s Irene ($4.4 billion).
On the top-12 list that includes historical storms with today’s exposures, only Katrina, Andrew and Sandy make the cut.
For his presentation, Weisbart relied in part on research done by Karen Clark & Co. for the current costs of historic hurricanes. Last year, PC360 provided the below infographic based on Karen Clark & Co.'s research.
