South Korea and the United States have reached a shared understanding that excessive volatility in the Korean won against the US dollar is undesirable, with the two countries pledging to maintain close consultations on foreign exchange market trends. The agreement was reached during a bilateral meeting in Washington on Friday between South Korean Finance Minister Koo Yun-cheol and US Treasury Secretary Scott Bessent, held on the sidelines of the Group of 20 finance ministers and central bank governors gathering.
The won has faced heightened pressure in recent trading sessions, driven largely by the ongoing US-Israeli war with Iran, which has pushed global oil prices higher and stoked concerns about inflation and an economic slowdown. South Korea, a major energy importer with an export-oriented economy highly sensitive to currency swings, is particularly exposed to such external shocks. The two officials discussed the impact of the Middle East crisis on the South Korean economy, as well as strategies to stabilise supply chains for key minerals — an area of growing strategic importance for both countries.
On the trade front, Bessent welcomed South Korea's steps to honour a bilateral investment commitment, including the National Assembly's passage in March of a special bill underpinning Seoul's pledge to invest $350 billion in the United States. The endorsement signals continued momentum in the bilateral economic relationship even as global trade tensions remain elevated.
Separately, Koo met with International Monetary Fund Managing Director Kristalina Georgieva, briefing her on Seoul's measures to cushion the economic fallout from the Iran conflict while preserving fiscal discipline. Georgieva indicated that South Korea has adequate fiscal space and that its commitment to medium-term fiscal soundness would support stable public financial management — an assessment that offers Seoul some reassurance as it navigates a complex international environment.
The joint currency statement is significant because explicit bilateral acknowledgement of exchange-rate concerns is relatively rare and can signal a willingness by both sides to coordinate responses if volatility worsens. For South Korea, securing US recognition of the won's instability provides a degree of diplomatic cover for any future market intervention measures its authorities might consider.
