Navigating the Storm: South Korea-U.S. Tariff Talks and Investment Implications

South Korea’s Acting President Han Duck-soo faces a high-stakes negotiation as tariff disputes with the U.S. loom large. With a trade surplus hitting a record $55 billion in 2024 and U.S. tariffs threatening key sectors, the April 24 talks could redefine economic ties between the allies. Here’s how investors should position themselves amid the uncertainty.

The Trade Imbalance: A Catalyst for Conflict

The U.S. imposed 25% retaliatory tariffs on South Korean goods in 2024, targeting automotive giants Hyundai and Kia, semiconductor leaders Samsung and SK Hynix, and pharmaceutical companies. These measures, rooted in concerns over trade imbalances, have strained relations despite the existing U.S.-South Korea Free Trade Agreement.

Automotive stocks have already faced pressure, with Hyundai’s U.S.-listed shares down 12% since the tariffs were proposed. For investors, this sector remains a key barometer of negotiations’ success.

South Korea’s Playbook: Cooperation Over Retaliation

Unlike China or the EU, South Korea has opted for dialogue rather than tit-for-tat tariffs. Han’s strategy hinges on leveraging strategic concessions:
1. Energy and Infrastructure: Pledges to boost U.S. LNG imports and collaborate on shipbuilding, a sector where South Korea holds 23% of the global market.
2. Sectoral Liberalization: Addressing U.S. grievances over non-tariff barriers, including automotive emissions standards and pharmaceutical pricing.

The shipbuilding angle could be a game-changer. If Seoul secures tariff relief in exchange for U.S. naval contracts, it could stabilize earnings for firms like Hyundai Heavy (009190.KS) while benefiting U.S. partners like

(HII).

Political Crosscurrents: Leadership and Uncertainty

The negotiations occur amid a political vacuum. Former President Yoon Suk Yeol’s impeachment in early 2025 has shifted power to Han, an interim leader until the June presidential election. This instability introduces risks:
- A new administration may recalibrate trade priorities.
- Domestic industries, such as pharmaceuticals, could resist reforms demanded by the U.S.

Investors should monitor South Korea’s ruling party dynamics, as the election outcome may determine whether the “cooperation-first” approach endures or hardens into retaliation.

Investment Considerations: Sectors to Watch

  1. Automotive & Semiconductors:
    Near-term volatility persists. Both Korean firms have underperformed Intel by 15% YTD, reflecting tariff fears. A resolution could catalyze rebounds.

  2. Energy & LNG:
    South Korea’s pledge to boost U.S. LNG imports aligns with Cheniere Energy’s (LNG) expansion plans. A 30% year-over-year increase in 2024 signals opportunity for U.S. energy stocks.

  3. Shipbuilding:
    Hyundai Heavy Industries’ (009190.KS) order book, already 85% filled for 2024, could grow if U.S. partnerships materialize.

Conclusion: A Delicate Balance

The talks are a high-wire act balancing economic pragmatism and political survival. If successful, they could unlock a “win-win” scenario:
- For South Korea: Tariff relief for autos and semiconductors, preserving export-led growth (which accounts for 45% of GDP).
- For the U.S.: Reduced trade deficits and access to critical sectors like LNG and shipbuilding.

However, failure risks prolonged trade friction, hurting both economies. Investors should remain cautious until a deal is finalized, focusing on diversification. Monitor the automotive and energy sectors closely, as their performance will likely mirror the negotiations’ trajectory. With $55 billion in trade and a geopolitical alliance at stake, the stakes couldn’t be higher.

Analysts project GDP growth could dip to 2.1% in 2025 without a resolution, versus 2.8% with a favorable outcome. The path forward is fraught, but the payoff for investors who navigate it wisely could be substantial.
