REPO Implementation Act of 2025

This bill implements the Porto Declaration by creating a "Ukraine Support Fund" to use Russian sovereign assets frozen in Europe (primarily held by G7/EU nations excluding the U.S.) for Ukraine’s benefit. It requires the U.S. government to transfer these assets into the fund without confiscation and mandates quarterly disbursements of at least $250 million to Ukraine until the war ends. The bill also requires the President to report to Congress on Russian assets held in covered countries (G7/EU members) and urges diplomatic efforts to persuade those nations to repurpose 5% of their assets quarterly for Ukraine. These provisions amend the existing "Rebuilding Economic Prosperity and Opportunity for Ukrainians Act" to operationalize the asset transfer mechanism.
