The Won's Crossroads: Navigating U.S. Scrutiny and Investment Opportunities in South Korea's Export-Driven Economy

South Korea's inclusion on the U.S. Treasury's foreign exchange monitoring list for the second quarter of 2025 underscores a critical juncture for its currency and economy. As the won nears the psychologically significant 1,400 mark against the dollar, investors must weigh the risks of U.S. trade pressure against opportunities in sectors like automotive and tech. With Seoul under the spotlight for its trade surplus and current account imbalances, the path forward for the won—and the assets tied to it—depends on whether policymakers can balance growth, currency stability, and diplomatic relations.

The Monitoring List: A Sword of Damocles Over the Won

The U.S. Treasury's June 2025 report reaffirmed South Korea's place among nine economies on its monitoring list, citing its $50 billion bilateral trade surplus with the U.S. and a current account surplus of 3.7% of GDP. While these figures triggered scrutiny, Seoul avoided the “currency manipulator” designation by not meeting the third criterion: persistent forex market intervention. However, the monitoring status alone is a strategic tool for Washington, potentially amplifying pressure to reduce trade imbalances through policy shifts rather than outright sanctions.

The won's weakness—driven by geopolitical tensions, U.S. protectionist rhetoric, and domestic political instability—has created a paradox. A weaker won boosts export competitiveness for tech giants like Samsung and automakers like Hyundai/Kia, but it also risks triggering U.S. retaliation. The Treasury's report emphasizes transparency and balanced growth, suggesting Seoul may face demands to adjust policies that indirectly support currency undervaluation, such as fiscal stimulus or trade agreements.

Sector Implications: Tech and Auto at the Helm

South Korea's export-driven economy relies heavily on its tech and automotive sectors, which account for over 40% of its GDP. A weaker won historically benefits these industries by lowering the dollar cost of exports. However, prolonged U.S. scrutiny could disrupt supply chains or lead to tariffs on key products.

Automakers like Hyundai and Kia face dual pressures: a weaker won improves export margins, but U.S. trade negotiations could impose new barriers. Similarly, tech firms like Samsung Electronics and SK Hynix benefit from a depreciating won but must navigate potential U.S. demands for “fair” currency valuations.

Investment Strategy: Betting on Policy Adjustments

The Treasury's monitoring list serves as a negotiation lever rather than an immediate threat. Investors should position for two scenarios:

1. Won Appreciation Play: If Seoul implements policies to stabilize the won (e.g., fiscal consolidation or reduced trade surpluses), the currency could rebound toward 1,300 per dollar. This would favor won-denominated bonds, such as KTB Government Bonds or the iShares J.P. Morgan USD Emerging Markets Bond ETF (EMB), which include Korean debt.

South Korea's bond market offers a yield premium over U.S. Treasuries, with low correlation to equities. A stronger won would amplify returns for dollar-based investors.

1. Equity Exposure with a Safety Net: Investors bullish on South Korea's long-term growth can consider ETFs like the iShares MSCI South Korea ETF (EWY) or the KINDEX KOSPI 200 ETF (KOSE). However, pair these with options strategies to hedge against won volatility.

Risks and Considerations

• U.S.-South Korea Trade Dynamics: A Trump administration's protectionist stance could lead to targeted tariffs on automotive or tech imports, hitting sectors hardest.
• Geopolitical Uncertainty: Tensions in the Middle East or North Korea could further weaken the won.
• Monetary Policy: The Bank of Korea's reluctance to raise rates to support the won may limit its ability to combat depreciation.

Conclusion: Position for Policy Resolution

South Korea's monitoring status is less a punitive measure than a catalyst for dialogue. Investors should anticipate that Seoul will seek to avoid escalation by adjusting trade policies, fiscal spending, or currency interventions. A gradual won appreciation—driven by reduced political risks and improved trade balances—could emerge by year-end, rewarding those who position in bonds or ETFs now.

For the bold, this is a time to buy South Korean assets at a discount, but with eyes wide open to the risks of U.S.-Korea tensions. The won's fate will hinge on whether Seoul can navigate Washington's demands without sacrificing its export engine—a balancing act with high stakes for global investors.

Final Note: Monitor the won's proximity to 1,400 and U.S.-South Korea trade talks. A breach of that level could trigger panic, while a rebound might signal policy success.
