Which of the following is considered a federal regulation example in insurance?

Medicaid as a joint federal/state endeavor is considered a federal regulation example in insurance because it involves the collaboration between federal and state governments to provide healthcare coverage to eligible individuals. The federal government sets certain guidelines and provides funding, while states administer the program according to both federal and state laws. This partnership exemplifies how federal regulations can influence and shape insurance programs by establishing minimum standards and funding requirements, which states must then incorporate into their own systems.

In contrast, the other options represent initiatives that are primarily governed at the state or local level rather than through federal regulation. For instance, municipal bond insurance pertains to debt security issued at the local level, while state-run insurance exchanges and local property and casualty regulations are entirely managed by state governments, reflecting state-specific needs and policies rather than federal oversight.
