Overview
- Treasury said on July 23 that no major trading partner met the threshold for a formal ‘currency manipulator’ label for 2025, but 10 economies remain under enhanced monitoring.
- The monitoring list includes China, Japan, South Korea, Taiwan, Thailand, Singapore, Vietnam, Germany, Ireland and Switzerland, all carried over from the January report.
- Treasury revised its approach in January 2026 to judge whether interventions that smooth exchange-rate moves are being used to resist depreciation as well as to resist appreciation.
- South Korea met two of the three statutory tests — a large bilateral surplus with the U.S. and a current-account surplus of 6.6% of GDP — and the report said the won faced sustained depreciation pressure; Seoul says it will keep close talks with Washington to protect market stability.
- Thailand, Singapore and Switzerland each met only one statutory criterion and could be removed from the watchlist if they fail to meet a second test by the next semiannual report; a manipulator designation, which was not used, would trigger intensified U.S. engagement and possible trade actions.
