Insurance companies cannot raise premiums instantaneously to reflect incurred losses. That's because rate changes—in most states—must be submitted and reviewed by the state's department of insurance before they can go into effect. As a result, rate changes that are brought on by a loss-causing event—such as a hurricane—may take some time to go into effect.
