Two recent letters submitted to US Treasury officials by insurance trade groups try to defend state regulation, while advocating deregulation. In a Nov 16, 2007, letter to the Department of the Treasury, the Independent Insurance Agents & Brokers of America (IIABA) acknowledged the need for a vital but limited federal role in insurance regulation. The IIABA letter acknowledges that the current state system of insurance regulation does have significant strengths -- particularly in the area of consumer protection -- and is a system worth streamlining and making more efficient and effective for consumers and the industry. The letter submitted to the Treasury Department by the National Association of Mutual Insurance Cos adopted a more strident voice in calling for radical change to insurance regulation, or more precisely deregulation. The mutual insurers have chafed under the private regulation of regional fire insurance cartels that existed prior to the US v. South-Eastern Underwriters Association case, and they chafe under state regulation of prices and products today.
