Flood risk AI is now a reliable tool- is there a desire to put it to work?


Flood insurance has been a wallflower at the coverage dance- an eager participant but not able to find a suitable partner.  Innovation efforts have found suitable risk prediction partners for carriers- FloodMapp, Hazard Hub, and Previsico among others- but is the flood insurance market ready?

Politics, inertia, customer preferences and regulation might keep the music from playing.

Flooding causes damage globally in tens of billions of dollars/euros per year, and the bulk of that amount is uninsured.  Choose your source for insured/uninsured percentages- the conclusion is the same- flooding is a risk with global effects, and flooding is a risk that is globally accepted as difficult to underwrite.  Flooding is hard to predict, has regional effects involving huge numbers of properties, and subject to moral hazard perspective by property owners.  Consider these indicative data from McKinsey :

Hard to predict is a real problem-if the probability of risk cannot be reasonably calculated, and the extent of possible risk is elusive, that sure makes an actuary’s job difficult. In the U.S. those problems were finally acknowledged as nonviable issues for the private insurance industry and a government program was established in the early 1970’s to address the risk, the National Flood Insurance Program (NFIP).  The underpinning of the NFIP was flood cover that was limited, was driven by a property’s location within flood maps drawn by risk exposure over time, and by the relative elevation of a property to risk (creeks, streams, rivers, wave and surge, etc.)

Fast forwarding to today that program morphed into a moral hazard, subsidized, under-funded monster that even in high risk areas had a low take up rate among property owners.  Mapping data became political footballs (no one wants a property that is in a designated Special Flood Hazard Area, SFHA), premiums became unbearable due to the effects of moral hazard/adverse selection, and outside of mortgagee requirements there is little societal or economic coercive pressure for a property owner to obtain the cover.  SFHA- a one in a hundred probability of a damaging flood?  I’ll take those odds and my chances, most property owners said.  And over time?  Persons who obtained the cover and suffered losses often simply repaired and waited for the next event, being indemnified multiple times without any underwriting consequence other than premium creep.  Those who had no cover either self-repaired or waited for government support in the form of grants or low-interest loans.

Human nature prevailed after 2005’s Hurricane Katrina, when flood/surge losses exceeded $100 Bn, and the number of US flood policies peaked the following few years to 5.7 million, only to decline more than 10% since then (see below):

And here’s a well-kept secret of the NFIP- claims can be adjusted only by flood-certified adjusters due to policy differences from private plans, and of course the bureaucracy’s zeal to restrict how flood funds are spent.  Subsidize the heck out of the program, but restrict efficiency in handling when indemnity is needed to jump-start recovery.

What of  countries other than the US?

There are few government subsidized flood programs elsewhere; most flood programs that are available are tied to property policies as extensions of cover (hello again, adverse selection issues) or bundled cover with more traditional policies.

An exception to lack of subsidized cover is the UK’s Flood Re initiative that cedes risk in excess of premium calculations to a not-for-profit organized as a backstop for carriers that is in the end supported by all insurers by market share.

Parametric options are becoming more accepted as alternatives to the complex nature of flood indemnity predictions.

So, it’s agreed that flood damage is a growing problem, and options for carriers and customers have been few.  However- if the probability of flood risk can be assessed and ‘tightened’, does that not move flood risk into a more traditional risk role?  The ongoing issues with US flood maps are that not only are the maps supported primarily by property elevation data that may have been influenced by politics, but that the mapping results are static until the next official surveys, and the mapping data are narrow in their basis- elevation, proximity to the water risk, and calculation of risk probability that is always backwards looking.

Consider some of the risk assessment/prediction innovators:

With the advent of availability of these and other risk prediction tools, will the insurance industry leverage the detailed analyses into more widely available, less costly and more desirable flood products?

Some considerations:

There’s plenty to discuss about flood insurance, its magnitude of insurance gap, subsidization of cover, and potential if the private market becomes the primary flood insurance vehicle.

The presence of innovative AI risk analysis, predictive programs, and reasonably inexpensive access to same by carriers and insureds just might prompt a new tune for flood insurance, which surely would be a welcome addition to the insurance dance card.
