Oklahoma Adopts New Rate Approval System for Insurers

In 1988, California enacted Proposition 103, mandating that insurers substantiate rate increases and secure state approval prior to implementation. Decades later, this regulatory framework has resulted in significant market challenges, with several major insurers reducing their presence in the state and the FAIR Plan's exposure seeing a substantial rise. Oklahoma is now moving toward a similar model with the newly signed House Bill 3781.

Effective July 1, 2027, this legislation shifts Oklahoma from a use-and-file to a file-and-wait system, requiring prior state approval for rate increases. Insurers in competitive markets must submit proposed rate increases 30 days in advance, while those in non-competitive markets face a 60-day lead time. The Oklahoma Insurance Commissioner, Glen Mulready, will have the authority to examine these filings and may demand additional actuarial data if required. Proposed rate changes will also be made available publicly for home, auto, and fire policies.

The policy, spearheaded by Representative Dell Adams and receiving bipartisan support, seeks to address ongoing premium increases in Oklahoma, which has among the highest average homeowners' premiums in the United States. Rising costs are driven by severe weather events, inflation, and increased reinsurance expenses, factors that may persist and further elevate rates.

Despite support for the bill, Commissioner Mulready expressed concerns that the measure does not address the fundamental causes of the premium hikes. He highlighted that while rates are reflective of Oklahoma's risk environment, the law might not diminish those underlying costs.

California's experience underscores the complexities of rate approval systems, where delayed processes can result in uncompetitive rates. As seen when consumer intervenor participation extended review times to over a year, such constraints can lead insurers to withdraw from the market rather than absorb losses.

This pattern poses a potential risk for Oklahoma, a state prone to significant weather events. The persistent challenge of balancing regulatory oversight with the need for actuarially justified rates remains critical. Oklahoma’s legislative response, although addressing political and consumer concerns, may not comprehensively mitigate the structural risk factors inherent to its insurance market.

As Oklahoma implements its new system, regulators and legislators must consider whether it effectively meets consumer interests or inadvertently pressures insurers to reconsider market participation. The experience of other states, such as California and Florida, serves as a cautionary reminder of the complexities involved when regulatory frameworks confront significant catastrophe exposure.
