HB 415 requires Tennessee's state government (via the Tennessee Advisory Commission on Intergovernmental Relations, TACIR) to study and propose actions to protect the state's financial security and sovereignty. The study must address six key areas: ensuring reliable supply of essential goods during disruptions, reducing dependence on centralized systems (like energy and communications), creating backup plans for electronic transactions, reviewing contracts to avoid constitutional conflicts, and boosting local production of critical goods. TACIR must submit its recommendations to the legislature by September 1, 2025. This bill does not change current laws but mandates a state-level analysis of potential vulnerabilities in supply chains, finances, and infrastructure.
