“Insurance companies have been very clear-eyed about climate change for a long time and the effect that has on their balance sheets,” Wharton professor of real estate and finance Benjamin Keys said on a radio show that airs on SiriusXM. Keys added, “And that will lead to higher premiums in risky areas. That’s what my research has borne out over these last few years. Insurers have sharply increased the ways in which they price disaster risk.”
Keys sees the insurance premiums to increase in the areas vulnerable to climate and expects them to be capitalized into house prices. He further added “But regardless, the position that homeowners will be in is one of substantially higher premiums.”
