Should the government prioritize commercial viability over political objectives for international investment projects?
President Lee Jae Myung has mandated that commercial viability is a strict precondition for all U.S.-bound investment projects, including the Alaska LNG development. These new requirements also standardize the bilateral profit-sharing ratio at 5:5 for the life of projects.
Why it matters
The government is shifting these terms to minimize investment losses and ensure the recovery of principal and interest. This marks a departure from previous agreements that allowed for higher returns for investors after the initial repayment phase.
The new 5:5 profit split for investment projects replaces a prior structure that allowed for a 9:1 split after the recovery of principal and interest. The policy applies to major developments like the 8 large nuclear power plants recently announced.
The players
Lee Jae Myung
President of South Korea who is prioritizing fiscal oversight and rigorous commercial verification for international infrastructure investments.
Donald Trump
President of the United States who is utilizing bilateral infrastructure investments as a component of trade and tariff policy.
The details
The government will now require individual feasibility reviews to verify commercial viability before project development begins. All proposed U.S. investment projects must undergo this compliance check under Republic of Korea legal procedures. The standardized 5:5 profit split remains in effect even after the full recovery of principal and interest, directly impacting the long-term return profile for participating entities.
Timeline
September 30, 2026: The U.S. government announced the initial investment projects.
October 1, 2026: President Lee Jae Myung clarified the requirements for project feasibility.
Market Landscape
This policy marks a departure from the 9:1 profit-sharing agreement by locking in a 5:5 ratio for the entire duration of investment projects. It reflects an evolving approach to cross-border capital allocation where state-led infrastructure investment is increasingly tethered to strict commercial hurdles.
Operators in sectors like energy and nuclear infrastructure should adjust their long-term ROI models to account for the permanent 5:5 profit-sharing cap. Review the specific feasibility criteria for your project type to ensure compliance with the newly required government viability reviews.
The takeaway
The move toward mandatory commercial viability verification signals that major bilateral projects will face higher oversight hurdles moving forward. Monitor these feasibility review outcomes closely to determine whether planned infrastructure projects remain viable under the new profit-sharing constraints.
