Should the government restrict U.S. investment in foreign companies to protect national security interests?
The U.S. Department of the Treasury has issued a Notice of Proposed Rulemaking to implement the Comprehensive Outbound Investment Security Act. The proposal formally includes biotechnology among the technology sectors subject to investment restrictions.
Why it matters
The Act seeks to ensure that American capital does not support the military modernization, surveillance capabilities, or human rights abuses of foreign adversaries. By expanding regulatory oversight to biotechnology, the government aims to close potential security gaps in sensitive emerging industries.
The regulations establish technical parameters for prohibited and notifiable transactions across five specific technology sectors. The Treasury Department is authorized to expand these definitions through future notice and comment cycles.
The players
U.S. Department of the Treasury
This federal executive department is responsible for managing government revenue and overseeing economic and financial policy.
The details
The proposed rules apply to U.S. persons and controlled foreign entities, requiring notification for certain transactions while prohibiting others involving designated foreign persons. These measures cover advanced fields including artificial intelligence, quantum computing, and hypersonic systems.
Timeline

October 22, 2026: The Treasury issued the Notice of Proposed Rulemaking.
The Tech Race
The proposed rules follow the framework established by the Fiscal Year 2026 National Defense Authorization Act to secure critical supply chains. These measures represent a strategic pivot to prevent dual-use technologies from providing a competitive advantage to foreign adversaries.
Investors and firms involved in international capital markets must now prepare to comply with new notification and prohibition requirements for biotechnology transactions. Compliance strategies will need to adapt as the Treasury formalizes the technical definitions for these sensitive investments.
The takeaway
These proposed rules signal a broader government effort to integrate national security concerns into private investment decision-making. Stakeholders should monitor upcoming final regulations to understand the specific compliance obligations for their international technology holdings.
