South Korea trade talks with U.S. deadlocked over forex, Seoul says

South Korea's finalization of a U.S. trade deal, which includes a $350 billion investment package, is delayed due to concerns over its potential impact on the domestic dollar-won exchange market. Presidential Policy Secretary Kim Yong-beom emphasized that South Korea's foreign exchange conditions differ significantly from Japan's, making the won vulnerable to downward pressure from such a large capital outflow. This critical foreign exchange stability issue is a key point in ongoing consultations, requiring resolution before the agreement can be finalized.

Analysis

The finalization of a major South Korea-U.S. trade deal is currently stalled due to significant concerns from Seoul regarding a proposed $350 billion investment package into the United States. South Korean officials assert that this large-scale capital outflow poses a substantial risk to the stability of the dollar-won exchange market. They differentiate their position from Japan's recent deal by highlighting critical disadvantages: the won is not an international currency, and South Korea lacks Japan's extensive currency swap programs and foreign exchange reserves, which are three times larger. The scale of the proposed $350 billion investment is a key point of contention, as it vastly exceeds the typical $20-30 billion annual overseas procurement capacity of state-run banks and the $2-3 billion in monthly overseas investments by the national pension fund, a factor already known to pressure the won. While the currency has strengthened 6% year-to-date to around 1,390 per dollar after hitting 15-year lows in 2024, the potential impact of the investment package could easily reverse these gains. Consequently, currency policy has been officially placed on the agenda for the trade talks, making a resolution on FX stability a prerequisite for any final agreement.

Key Decisions for Investors

• Investors with exposure to the South Korean won (KRW) should anticipate significant depreciation pressure and heightened volatility should the $350 billion U.S. investment package proceed without sufficient FX stabilization measures.
• The delay and uncertainty surrounding the trade deal introduce a key headwind for South Korean equities, warranting a cautious stance on unhedged investments in the domestic market until a resolution is announced.
• Portfolio managers should closely monitor negotiations for any news of a currency swap line or other support mechanisms, as such developments would be the primary catalyst to de-risk the situation for both the KRW and the broader South Korean market.
