Insurance answers to the states, not to one Washington agency. A carrier needs a license in each state where it sells. The local regulator reviews its rates, its forms, its sales conduct, and its finances. The split of labor is a statute, not a habit. In 1945 Congress declared state regulation of the insurance business a public interest. Federal silence, the law says, leaves that power in state hands. The rule still governs. The strain shows at the edges: one national market, many local rulebooks.
The power is real but checked. The federal layer built after the 2008 crisis watches the market. It does not supervise carriers. A working inventory of what do insurance regulators do fits in four piles of paper. The piles: solvency filings, market conduct reports, producer licenses, and form approvals. Ownership matters elsewhere in the machine too. Even the federal permitting backlog now has a named owner. This review sits on the policy desk, which tracks rules from drafting to enforcement.
Which Level of Government Sets the Rules?
State government does, under the McCarran-Ferguson Act of 1945. The statute says federal silence must not block state rules or state taxes. Each of the 50 states, the District of Columbia, and five territories keeps a chief regulator. They coordinate through the National Association of Insurance Commissioners. The group founded in 1871 is governed by those same chief regulators. It drafts model laws and data standards. A model binds nobody until a legislature adopts it. That two-step is the design: common paper, local force.
What Actually Lands on a Regulator's Desk?
Paperwork. Each pile has a job. Carriers file financial statements so the state can test solvency. The NAIC's risk-based capital groups set the standards behind those tests. Market conduct annual statements flag sales and claims conduct. Producer databases license the agents who sell. Company licensing runs through the uniform certificate of authority process. State rules attach to each filing. The desk work is dull and load-bearing. An insurer that drifts toward trouble shows up first in weak filings. Enforcement then runs from conduct exams to license actions under state process. This connects to our earlier piece, Federal Permitting: The Backlog Now Has an Owner and a Clock.
Where Does Washington Fit In?
Beside the states, not above them. The Dodd-Frank Act set up the Federal Insurance Office inside Treasury. A career director in the Senior Executive Service runs it. Its brief by law covers monitoring all aspects of the insurance industry. That includes gaps in the rules that could feed a systemic crisis. The office also builds federal policy on prudential parts of global insurance. It serves as a non-voting member of the Financial Stability Oversight Council. It helps the Secretary negotiate covered agreements with other countries. It watches and advises. It does not issue licenses. Solvency stays with the state, and the two roles do not swap.
Why Does the Patchwork Persist?
Congress chose it in 1945 and renews the choice by inaction. Reform runs through the NAIC. Its model laws spread uniform language one statehouse at a time. Its accreditation program sets a floor for how each state runs solvency checks. The Financial Regulation Standards and Accreditation Committee runs those reviews. The cracks show in speed. A standard the market needs nationwide waits for dozens of adoptions. Approvals can drift for months across states that share no calendar. The workaround uses the same machinery: draft once, adopt locally, audit under that program.
Conclusion: Follow the Filings to Find the Power
The map starts with a license and ends with a financial statement. States hold the supervisory power under the 1945 statute. The NAIC drafts the common standards that keep fifty-plus rulebooks roughly aligned. The federal office watches for systemic risk and runs none of the day to day. The mechanism rewards one habit. When a story blames or credits coverage rules, check which desk touched the case. A solvency problem belongs to state examiners. A cross-border prudential deal belongs to Treasury. The paperwork shows which government moved. For related coverage, see Two Years After Chevron: How Agencies Now Write Rules.
