After a slow start, hurricane season has taken a significant toll in North America this year. Hurricane Fiona devastated Canada’s Atlantic provinces, leaving hundreds of thousands of people without power. Less than a week later, Hurricane Ian laid waste to vast areas of Florida and the Southeastern United States, resulting in $70 billion to $120 billion USD in damage.
The risk of hurricanes is nothing new. But their frequency and their toll are continuing to rise.
The risk of hurricanes is nothing new. But their frequency and their toll, both human and economic, are continuing to rise.
For businesses, it’s a phenomenon known as climate-related physical risks, and can be attributed in part to climate change, and also to the continued development of high-valued properties in disaster-prone areas.
When a hurricane, wildfire or flood hits, the cost of recovery and repair is that much higher.
Climate-related physical risks
The result is that businesses of all kinds must account for these risks and factor them into their strategic decisions. Few corners of the economy are immune, including agriculture, transportation, the supply chain and infrastructure.
No longer is extreme weather the concern of a limited number of coastal communities, or low-lying areas.
All investments have inherent risks, of course. But some risks are greater than others, and measuring these risks helps businesses determine their exposure and their level of resilience to emerging threats.
Identifying such risks also helps guide investment decisions, such as what to invest in, where to place those investments and when to do it.
With so much uncertainty surrounding climate change, it is important to conduct scenario analysis to understand the effect of each climate scenario on investment portfolios and business strategies.
For example, a company might decide to build a manufacturing plant in a different location after finding out that the first location would be at an elevated risk of flooding.
Climate-related physical risks also affect the value of assets because weather events can destroy physical capital. For investors, this means that borrowers might not be able to repay their loans.
Repeated events can lead to devaluations of real estate, even if they do not directly damage the properties. In addition, when extreme weather events occur, households and businesses draw on cash reserves and credit lines, which can affect liquidity.
All these should be accounted in investment and business strategies.
Insurance takes the lead
Even as many industries are starting to account for these risks, one industry has been on the forefront of incorporating climate change in business decisions: insurance.
Businesses and households rely on insurance to cover the cost of damage. When extreme weather events occur, insurance companies pay out claims, which often leads to higher premiums for everyone.
More and more, insurance companies are building climate-related physical risks into their models when calculating premiums or determining whether an asset can be insured.
For example, owners of houses with wood frames now pay higher premiums because of wildfire risks, while those in flood-prone areas have been paying increasingly high premiums for flood insurance.
Even getting a policy from a private insurer is not a sure thing; when the risks are too high, insurance companies might refuse to insure the asset altogether.
There is little surprise, then, that insurance companies have taken the lead not only in acknowledging climate risks but also in quantitatively factoring those risks into their business decisions.
After all, insurance companies have long investment horizons, and managing risks is the very backbone of insurance.
Accounting for climate risks
But other businesses have been slow to catch on, even though many have investments that are subject to climate risks.
Climate risks can be complex to assess and have a longer time frame. At the same time, many investors have shorter time horizons and are focused on the project at hand rather than macroeconomic implications.
Even financial institutions are still at the early stages of building capacity to assess climate-related physical risks. Similarly, few businesses quantify the impact of climate risks on their business strategies and investment portfolios.
But failure to factor in these risks can lead to suboptimal investment decisions with consequences on the return on investment, liquidity, as well as the viability of the business.
This year’s hurricane season, even after its slow start, has exacted a significant toll, both in loss of life and economic damage. Climate-related physical risks translate to expensive events that are expected to continue.
While there is substantial uncertainty and complexity associated with climate risks, ignoring them does not make the issue go away.
Rather, businesses must reduce their vulnerability to climate risks. This includes diversification, and, more importantly, understanding and quantifying these risks. Only then will climate risks be priced in and effectively managed in investment and business decisions.
