House Bill No. 1561, known as the Foreign Adversary Divestment Act of 2025, aims to protect Oklahoma public investment funds from being invested in foreign adversaries, defined as countries designated as hostile by the U.S. Secretary of State. The bill mandates that all state and local managed funds must divest from any investments in foreign adversaries, companies controlled by them, or banks domiciled in those countries, with a complete divestment deadline set for January 1, 2028. The State Treasurer is tasked with developing a notification system to identify these foreign adversaries and ensure compliance with the divestment requirements.

Additionally, the bill provides immunity from liability for public pension systems regarding losses in asset value due to compliance with the act. It outlines the definitions of key terms such as "divestment," "foreign adversary," and "state-managed fund," and emphasizes that the act should not conflict with existing financial safeguards or fiduciary responsibilities. The provisions of the act will take effect on November 1, 2025.
