Insurance coverage premiums are more likely to proceed rising, brokers mentioned, and property homeowners searching for insurance coverage additionally should shoulder larger retentions, preliminary prices they have to bear themselves earlier than insurance coverage kicks in. “We don’t count on to see a discount in capability out there for twister protection,” mentioned Dave Causes, Marsh’s U.S. Central Zone Property Chief.
