US Treasury Proposes Wider Curbs on Outbound Technology Investment

The US Treasury Department issued draft rules on Thursday, 22 October, to expand its screening of certain American investments in sensitive technologies overseas. The proposal would implement the COINS Act and update the existing Outbound Investment Security Program.

The draft covers six technology areas: semiconductors and microelectronics, artificial intelligence, quantum technology, high-performance computing and supercomputing, hypersonic systems, and biotechnology. Treasury said it added biotechnology using authority granted by Congress.

Under the proposed framework, US investors would have to notify Treasury about some covered transactions, while others would be prohibited. The rules would target specified foreign entities and activities, rather than impose a blanket ban on investment abroad.

Treasury is accepting public comments until 7 December 2026. It said it would review that feedback before publishing final regulations, which would set an effective date.

The distinction matters for businesses planning cross-border technology deals: this is a consultation on expanded controls, not an announcement that all of the proposed changes already apply.
