This bill, known as the Dollar Dominance Act of 2025, establishes the Office of Strategic Currency Diplomacy within the Department of State's Bureau for Commercial Diplomacy. This new office is tasked with safeguarding the United States dollar's status as the world's primary reserve currency. Its responsibilities include actively combating efforts by strategic rivals to undermine the dollar and partnering with allies to ensure the strength and integrity of U.S.-dollar denominated financial systems. The office will also evaluate the implications of virtual assets for U.S. foreign policy and national security, while aligning foreign policy, including sanctions, with national monetary security objectives. Furthermore, the Office of Strategic Currency Diplomacy will serve as the principal advisor to the Assistant Secretary for Commercial Diplomacy on policies to prevent a reduction in the dollar's international use. It will coordinate with various federal departments, such as the Treasury and Commerce, to develop strategic plans aimed at protecting the dollar's preeminence and expanding its share in central bank foreign currency holdings and international transactions. A key function involves monitoring and developing strategies to counter the proliferation and adoption of Central Bank Digital Currencies in other nations, thereby protecting the dollar's standing and national economic security. The office will also represent the Secretary in international engagements concerning virtual assets, including U.S. dollar payment stablecoins.
