This bill, titled the National Infrastructure Investment Corporation Act of 2025, establishes a new government corporation to address the significant infrastructure needs of the United States. The National Infrastructure Investment Corporation will provide loans and loan guarantees for a wide range of infrastructure projects, including transportation, energy, environment, and telecommunications, particularly those that exceed the financing capabilities of states and cities. Congress finds that current infrastructure is graded 'C' and requires an estimated $3.7 trillion in investment, with traditional funding sources being insufficient. The Corporation will be managed by a 7-member Board of Directors , appointed by the President and congressional leadership, with members required to have significant experience in infrastructure, finance, or government policy, and represent diverse geographic regions. The Board's responsibilities include setting strategic goals, monitoring effectiveness, approving budgets, and ensuring annual audits. An Inspector General will also be appointed to oversee the Corporation's activities and conduct investigations. Funding for the Corporation will primarily come from pension funds , with the Board authorized to accept up to $5 billion annually from fiscal years 2026 through 2030, at an annual interest rate between 3% and 4%. Eligible applicants must submit detailed project proposals and consult with affected members of Congress. All loans and loan guarantees will be subject to a 60-day congressional review period before final approval, and the Corporation will submit annual reports and audits to Congress, with the Government Accountability Office conducting evaluations every five years.
