Treasury Proposes COINS Act Rules for Outbound Investment Screening
Treasury's proposed rule to implement the COINS Act would build out notification and filing duties for certain U.S. outbound investments into countries of concern, adding a federal overlay on export controls and sanctions.
On October 22, 2026, the U.S. Department of Treasury issued a Notice of Proposed Rulemaking to implement the Comprehensive Outbound Investment National Security (COINS) Act, enacted as part of FY 2026 national defense authorization legislation. The proposal is the first step in building out a mandatory notification and filing regime for certain U.S. outbound investments into countries of concern.
For major-firm clients, COINS is becoming a new federal overlay on cross-border capital flows, sitting alongside export controls, sanctions and CFIUS-style review. Because the statute, the covered technology and covered country lists, the filing mechanics and any penalty exposure all still depend on the final rule, companies and private equity funds with existing or contemplated ties to semiconductor, quantum and other critical-technology counterparties in China and other covered jurisdictions are best served modeling notification triggers now rather than after adoption. The NPRM comment period and the content of the final rule are the immediate next developments to watch, along with any interim Treasury guidance and related export-control rulemakings that may align with it. Covered technologies, country lists and deadlines should be confirmed against the NPRM text, which was not reviewed in full for this summary.
