1. Overview of the U.S. Insurance Market

The U.S. insurance system is complex due to its combination of:

• Public programs

• Private insurers

• State-by-state regulations

• Employer-sponsored coverage

• Optional and mandatory insurance types

Unlike many countries where insurance is centralized, the U.S. divides responsibility between federal and state governments. Each state has its own insurance laws, regulators, and market conditions.

Key Characteristics of the U.S. Insurance System

• No universal national health insurance

• Heavy reliance on private insurance companies

• Strong employer-based health insurance

• Highly competitive insurance market

• Mandatory coverage in areas like auto insurance and homeowner policies for mortgages

• Federal involvement in Medicare, Medicaid, and other social programs

Because of these complexities, the U.S. is home to some of the world’s largest insurers, including State Farm, UnitedHealth Group, Kaiser Permanente, Allstate, Geico, MetLife, AIG, and Prudential.
