TSP Fiduciary Security Act of 2025

The TSP Fiduciary Security Act of 2025 requires the Federal Retirement Thrift Investment Board to manage the Thrift Savings Fund in a way that prevents investments or voting rights from harming U.S. national security. It specifically prohibits TSP investments in entities based in China or other designated "covered countries" (including Russia, North Korea, Iran, and others), entities that breach major government contracts, or those that reduce production of critical defense technologies. The bill mandates the Secretary of Labor to create regulations within one year to review TSP investments and voting rights for national security compliance, with annual reports to Congress detailing reviews and enforcement outcomes. This law directly affects federal employees and uniformed services members who use the TSP for retirement savings, particularly through restrictions on the TSP mutual fund window, which cannot include investments in China-based entities.
