S. 2375 — National Net Interest is National Security Act of 2025

This section requires the Secretary of the Treasury, in consultation with the Secretaries of Defense and State, to submit reports to the specified congressional committees assessing national security threats from projected increases in the national debt and net interest payments—(1) not later than one year after enactment and (2) thereafter concurrent with each national defense strategy under 10 U.S.C. §113(g). The reports must include (1) assessments of effects on defense discretionary spending, federal revenue, U.S. capacities to respond to defense needs, geopolitical threats, economic crises, and mandatory spending obligations (including Social Security, Medicare, and Medicaid); the dollar's role in global markets, U.S. credit rating, inflation, and interest rates; (2) the likelihood of net interest payments crowding out discretionary spending priorities such as national security, diplomacy, and public investments; and (3) legislative recommendations to mitigate these threats. This section further directs the Comptroller General to include such debt-related national security threats on the Government Accountability Office's High Risk List. "Appropriate congressional committees" are defined as the Senate Committees on Finance, Foreign Relations, and Armed Services; and the House Committees on Ways and Means, Foreign Affairs, and Armed Services.
