U.S. Treasury Proposes Updating Outbound Investment Restrictions in Strategic Technology Sectors
Key Facts
On October 22, 2026, the U.S. Treasury Department issued a notice proposing rules to update the Outbound Investment Security Program, implementing the requirements of the COINS Act. The notice puts the program amendments on a regulatory path that has not yet reached the effective stage, as the department said it would consider comments before issuing final implementing regulations. Treasury says the proposal targets certain U.S. outbound investments in strategic dual-use technologies that it believes could benefit the modernization of foreign countries’ military capabilities, surveillance systems or human rights abuses. This means the announcement concerns an expansion of oversight over certain transactions, not a general ban on outbound investment. The department has not yet set a start date for the updated program, leaving that to the final rules.
The proposal covers technical specifications in semiconductors and microelectronics, quantum technologies, superintelligent systems and hypersonic systems, as well as high-performance computing, supercomputing and biotechnology. These sectors put the focus of the update on technologies Treasury links to strategic and security purposes, rather than on all forms of investment in the countries concerned. The department says investment controls target specific categories and do not prohibit all investment activity in those countries. Whether the rules apply therefore depends on the nature of the technology, transaction and parties involved, according to the scope of the definitions the regulation will establish. Treasury also urges investors to assess each case, because the proposal may apply to some investments outside a country designated as a country of concern.
According to an Associated Press report published on October 22, the proposal’s notification requirement does not apply to investments valued at less than 50,000 dollars, and it exempts examples of financial investments, including stock purchases. This threshold and the exemptions put some financial transactions outside the notification requirement cited in the report, while the rule’s scope remains tied to transaction details. The proposal allows the public and stakeholders to comment on the scope of covered national security transactions, definitions of terms, notification requirements, penalties and enforcement mechanisms. Treasury says the comments will inform its review before it drafts the final rules, leaving coverage and implementation details open to revision at this stage. The department did not estimate the proposal’s impact on capital flows or listed companies.
Treasury official Chris Pilkerton told Reuters that the program’s purpose is “to ensure we have the ability to monitor, and potentially prohibit, types of investments that pose risks to U.S. national security.” The statement describes the program’s oversight function as Treasury presents it, combining the monitoring of investments with the possibility of blocking some of them. A former U.S. trade official, meanwhile, told the Associated Press that the proposal is “just the first step in a relatively long process to get to changes that are supposed to be more focused on enforcement.” The two statements reflect connected stages: a proposal that opens the door to public participation, followed by final rules that will define how it is applied. Issuing the notice alone does not mean the proposed restrictions have taken effect.
The update follows a regulatory process that began with an executive order issued by President Joe Biden on August 9, 2023, to address U.S. investments in technologies and products linked to national security in countries of concern. Treasury issued the previous final rule on October 28, 2024, and it took effect on January 2, 2025. According to the department, the current rules continue to govern activities that took place from January 2, 2025, until the new final rule’s start date. The proposal therefore does not immediately lift existing obligations upon its release, or replace them before the effective date of the new regulations is set. Treasury also emphasizes that an exception or exemption under the outbound investment program does not relieve an investor of obligations under other applicable U.S. government programs.
The next procedural step is to receive comments through December 7, 2026, the deadline set by Treasury. The department will review comments on the scope of transactions, definitions, notification, penalties and enforcement before issuing final implementing regulations. Treasury said those regulations will set the date the program takes effect, without announcing a date in the proposed notice. Until they are issued, the current rules remain the reference for activities they cover during the transition period. This timeline leaves the final implementation details subject to the outcome of the regulatory review.
