US Treasury Secretary Bessent says we have seen excess volatility in Korean Won

• Believes Chinese Yuan is undervalued.

US Treasury commentary on Asian FX follows a well-worn template: administrations in this posture have historically paired complaints about undervalued Chinese currency with remarks on regional peers, and such statements tend to land on the won, yen and offshore yuan as a basket rather than in isolation, since the region trades as a correlated bloc through the CNY fix and trade-flow linkages. The sequencing in past episodes has been consistent: verbal remarks first, then the question of whether they harden into formal designations, trade investigations or pressure within bilateral negotiations, with the Treasury's semiannual currency report the usual institutional vehicle. The charge that the yuan is undervalued is notable because it inverts the more familiar US complaint of competitive depreciation, and implies a preferred direction for the fix that Beijing has historically resisted externalising. The distinction worth drawing is between jawboning that fades within sessions and commentary that precedes policy, with prior form suggesting follow-through shows up in the fix itself and in any shift in official rhetoric from the counterparties rather than in immediate price action. Watchpoints are the next currency report language, any Korean response given the direct reference to won volatility, and whether the remarks recur across other administration officials.
