Wisconsin Office of the Commissioner of Insurance (OCI)

The Wisconsin Office of the Commissioner of Insurance (OCI) is the state agency responsible for regulating the Property & Casualty insurance industry in Wisconsin. The OCI operates under Wisconsin Statutes Chapter 600-646 and reports directly to the Governor.

The Commissioner of Insurance

The Wisconsin Insurance Commissioner is:

  • Appointed by the Governor
  • Confirmed by the Wisconsin State Senate
  • Serves at the pleasure of the Governor (no fixed term)
  • Chief regulator of Wisconsin's insurance industry
  • Authorized to adopt administrative rules, review rates, investigate violations, and discipline licensees

Current Commissioner (2026)

Nathan Houdek has served as Wisconsin Insurance Commissioner since 2022:

  • Appointed by Governor Tony Evers in 2022
  • Confirmed by Wisconsin State Senate in March 2023

Rate Regulation System

Wisconsin uses a file-and-use system for most P&C insurance:

File-and-Use Rate System

Key Provisions:

  • File-and-Use: Insurers file rates with OCI and may use them immediately without prior approval
  • Post-Implementation Review: OCI reviews rates after they're implemented
  • Commissioner Disapproval: OCI may disapprove rates if they violate state law
  • Rate Standards: Rates must not be excessive, inadequate, or unfairly discriminatory
  • Actuarial Support: Rate filings must include actuarial justification and supporting data

File-and-Use Process

  1. Insurer Files Rates: Submit comprehensive rate filing with actuarial support to OCI
  2. Immediate Implementation: Insurer may implement rates immediately upon filing
  3. OCI Review Period: OCI reviews filing within 30-60 days for compliance
  4. Approval or Objection: Commissioner approves filing or notifies insurer of objections
  5. Insurer Response: If objected, insurer must modify rates or request hearing
  6. Final Determination: Commissioner makes final determination on rate adequacy

Exam Tip: Wisconsin's file-and-use system differs from prior approval (Massachusetts) and use-and-file systems. Know that insurers can implement rates IMMEDIATELY but OCI reviews them after implementation.

Rate Standards Under Wisconsin Law

Wisconsin Statutes require that all P&C insurance rates be:

StandardDefinitionExample Violation
Not ExcessiveRates not unreasonably high for coverage providedCharging 200% of actuarially justified premium
Not InadequateRates sufficient to maintain insurer solvencySetting rates below claims costs, threatening solvency
