Record U.S. Trade Surplus Raises Concerns Over Economic Pressure

South Korea's trade surplus with the United States has exceeded $100 billion for the first time, raising concerns about potential economic pressures on the bilateral trade relationship. The Trump administration, which has prioritized reducing trade deficits, may respond to South Korea's growing surplus by demanding additional tariffs or increased investment in the U.S.

In anticipation of U.S. trade pressures, there are calls for strategies that include increasing imports of American energy and strengthening cooperation with local political leaders.

According to the Korea Customs Service, the cumulative trade surplus with the U.S. from January to October this year is approximately $102.26 billion. This figure combines the confirmed surplus of about $84.69 billion for the first nine months and a preliminary estimate of around $17.58 billion for October. However, the final surplus figure may vary as October's results are confirmed.

The trade surplus with the U.S. has increased from $11.4 billion in 2019 to $22.7 billion in 2021, and then to $44.4 billion in 2023, reaching a record high of $55.6 billion in 2024. Although it slightly decreased to $49.5 billion last year, the surplus has surged again this year, driven by increased demand for South Korean semiconductors and power equipment due to expanded U.S. investments in artificial intelligence (AI) data centers and infrastructure.

However, this growing surplus could trigger additional trade pressures from the U.S. The Trump administration had previously warned of imposing mutual tariffs of 25% on South Korea and 24% on Japan, citing the need to reduce trade deficits. Subsequently, South Korea committed to a $350 billion investment in the U.S., leading to an agreement to lower the tariff rate to 15%.

There are concerns that semiconductors, which have driven export growth, may become a new target for pressure. While South Korean semiconductor exports have surged due to increased U.S. AI investments, the Trump administration is pushing for expanded domestic semiconductor production and supply chain restructuring. If tariffs on semiconductors are implemented, this key industry could face significant trade uncertainties.

The Office of the U.S. Trade Representative (USTR) initiated a Section 301 investigation in March targeting 16 economies, including South Korea, regarding structural overproduction in manufacturing. The USTR specifically noted that South Korea's trade surplus with the U.S. reached $56 billion in 2024 and approximately $49 billion last year. A public hearing was held in May, leaving the possibility of additional trade measures as a variable.

Other trade remedy measures, such as anti-dumping and countervailing duties, are also being discussed. However, these measures require separate legal criteria related to dumping, subsidies, or industry harm due to increased imports, and are not automatically triggered by the size of the trade surplus alone.

Pressure for investment in the U.S. is already becoming a reality. In particular, ongoing U.S. demands for investment in the Alaska liquefied natural gas (LNG) development project are increasing South Korea's burdens. Both countries have agreed to review the investment based on the project's commercial viability, but President Trump has repeatedly called for South Korea's participation.

If the trade surplus continues to grow, demands for energy purchases or additional investments may intensify. However, South Korea must consider not only the alleviation of trade burdens but also the economic viability and investment risks associated with such projects.

Moreover, the U.S. may pressure South Korea to expedite the fulfillment of existing investment commitments worth $350 billion or demand additional local production facility investments. Consequently, there are recommendations for South Korea to increase purchases of American energy and enhance cooperation with U.S. lawmakers.

Professor Heo Yoon of Sogang University’s Graduate School of International Studies stated, "The government needs to manage imports of items that can diversify imports from the U.S., such as American energy, to prevent a rapid increase in the trade surplus with the U.S."

He added, "It is essential for South Korean companies to strengthen their relationships with governors and state legislatures in Texas, Louisiana, Alabama, and Indiana, as well as with federal lawmakers, to effectively respond to trade pressures."
