It has been a tough few months for the insurance coverage business. Third quarter outcomes are rolling in and much of corporations are reporting the identical factor – US pure catastrophes have hit us onerous!

2017 can be remembered for Hurricane Harvey and the extraordinary flooding it induced in Texas, adopted carefully by hurricanes Irma and Maria battering the Caribbean. Add to devastating earthquake in Mexico and raging wildfires in California … all within the house of a number of months.

Flood insurance coverage and flood modelling have been high of thoughts insurance coverage points for a while. Urgency across the flood difficulty actually hiked up a notch when the influence of Harvey grew to become clear. It was the topic of an occasion hosted by ArgoGlobal and Lloyd’s of London, the place comparisons had been made between 4 main flood threat modelling distributors: AIR, KatRisk, Impact Forecasting and CoreLogic. 

“We are experiencing one of the most active hurricane seasons this century,” stated David Clouston, head of Lloyd’s threat aggregation. “Widespread flooding as a result of windstorms Harvey and Irma has once again highlighted the costs of natural catastrophes – both in terms of human suffering and economic hardship. The need for a deeper understanding of inland flood modelling is more important than ever.”

The occasion was hosted by Federico Waisman, senior vp and head of analytics at Ariel Re. Waisman created an information set that was run via every flood threat mannequin utilizing the identical enter and mannequin choices. He then offered a comparability of outcomes (which had been fairly variable at instances) and allowed the distributors to elucidate their outcomes.

“This is a significant milestone for the modelling of inland flood in the US, and could not be more timely. We have witnessed time and again the devastation wrought by flooding. The models presented at this event will enable the insurance industry to better underwrite this risk,” he stated.

“The potential for growth in this area is clear. With the benefit of more robust analytics the flood market could represent an area of significant potential for (re)insurers. This event will enable the market to witness how these relatively new models perform, and gain valuable insights into their respective processes.”

Flood threat modelling undoubtedly has worth, however calculations are nonetheless enormously variable, as proven by some of the comparisons made on the ArgoGlobal occasion. The flood threat modelling market continues to be at its starting and there are nonetheless uncertainties that have to be unraveled, stated Siamak Daneshvaran, head of analysis and improvement at Aon Benfield Impact Forecasting.

All 4 distributors on the occasion agreed wholeheartedly on one factor – there’s an amazing alternative to delve into new information and use flood modelling to really analyse threat.

“None of these are out-of-the-box models,” commented Stefan Eppert, chief expertise officer and co-founder of KatRisk. “I advise companies to take the time to delve into risk model results and figure out how the data relates to your books and the best way to use it to come up with a [way to mitigate] that risk.”

Laurel Di Silvestro, senior product supervisor at CoreLogic added: “2017 happened! So we have an opportunity to do some real stress testing. My advice would be to [collect your data] get the flood maps and really start delving into some of these models.”
