South Korea's Lee and Bessent discuss conditions for US tariff deal

South Korean President Lee Jae Myung is advocating for "commercially rational" terms in ongoing trade talks with the U.S. regarding a proposed $350 billion investment package, citing concerns over potential destabilization of South Korea's currency market and foreign reserves, especially given the won's recent weakening past 1,400 per dollar. To mitigate these risks, South Korea is seeking an unlimited foreign exchange swap from the U.S., a proposal reportedly under review by Washington, as it aims to secure a deal without significant direct capital outflow.

Analysis

Trade negotiations between South Korea and the U.S. are facing significant headwinds over a proposed $350 billion investment package. South Korean President Lee Jae Myung's call for "commercially rational" terms underscores deep concerns about the deal's potential to destabilize the nation's currency market and deplete foreign reserves. These concerns are amplified by the South Korean won's recent breach of the psychologically critical 1,400 per dollar level, its weakest point since mid-May. To mitigate this risk, Seoul is requesting an unlimited foreign exchange swap line from the U.S., a proposal currently under review by Washington. The necessity of this backstop is highlighted by academic commentary suggesting the $350 billion investment is an "impossible number" without such a dollar liquidity guarantee, casting doubt on South Korea's capacity for a large-scale direct capital outflow. The situation presents considerable execution risk for the final trade agreement, with the U.S. decision on the FX swap now a pivotal determinant for market stability.

Key Decisions for Investors

• Investors should closely monitor the U.S. response to South Korea's request for an unlimited currency swap line, as a rejection would likely trigger further weakness in the won (KRW) and increase volatility in South Korean sovereign debt markets.
• Given the explicit currency risks highlighted, it is prudent for investors with exposure to the South Korean equity market to consider hedging their KRW positions to insulate portfolios from further downside.
• Adopt a cautious stance on unhedged South Korean assets, as the commentary suggesting the country lacks the funds for the $350 billion investment introduces a significant tail risk that is contingent on a geopolitical agreement for a liquidity backstop.
