A New US-Korea Economic Alliance: The Era of Managed Trade

On July 31, 2025, a new US-Korea Trade Agreement was concluded between South Korea and the United States. This agreement effectively replaces the existing US-Korea FTA with a new ‘managed trade’ system. It signals a shift from norm-based free trade to a transactional relationship that allows market access based on large-scale capital investment.

The agreement’s main points include ▲reducing US tariffs on Korean products from 25% to 15% ▲a $350 billion Korean investment commitment in the US ▲a $100 billion purchase commitment for US energy products. However, significant discrepancies remain between the two countries’ statements on details such as the full opening of the Korean agricultural market and the structure of investment returns, leaving room for future disputes.

In conclusion, this agreement avoids the worst-case 25% tariff scenario but comes as a pragmatic choice with substantial costs. What specific impacts will it have on our economy?

Core Conditions of the 2025 US-Korea Trade Agreement

This agreement presents a completely different paradigm from past FTAs. The linked structure of tariff adjustments with large-scale investment and purchase commitments clearly reflects a change in the nature of bilateral economic relations.

15% Tariff Regime: From Free Trade to Managed Equivalence

The biggest change is the reduction of US tariffs on Korean products from the initially proposed 25% to 15%. This aligns Korea with Japan and the EU, avoiding the worst-case scenario.

However, this also means the loss of preferential status under the US-Korea FTA, especially the elimination of tariff-free benefits for the automotive industry. Our negotiation team had pushed for 12.5%, but the US insisted on a uniform 15% tariff for major trading partners.

An interesting point is the differing interpretations of the term ‘reciprocal tariffs.’ The Korean government announced that both countries would impose 15% tariffs on each other, but then US President Trump declared, “The US will not be subject to any tariffs.” This discrepancy could spark future controversies.

$350 Billion Investment Obligation and $100 Billion Energy Purchase

At the heart of the negotiations is Korea’s $350 billion investment commitment in the US. This was the key condition demanded by the US in exchange for lowering tariffs to 15%.

President Trump announced that this investment would be “controlled by the US,” but our government explained it as support for Korean companies’ entry into US markets such as shipbuilding and semiconductors. Additionally, a $100 billion commitment to purchase US LNG and other energy products was included.

Industry-Specific Impacts: Opportunities and Challenges

This agreement casts different shadows over our major industries.

Automotive Industry: The Start of Strategic Restructuring

The imposition of a 15% tariff on the automotive industry is one of the biggest shocks. Losing the 0% tariff advantage under the US-Korea FTA, Korean automakers now start on equal footing with Japanese and European competitors.

Securities analysts estimate that this tariff could reduce Hyundai and Kia’s annual operating profit by about 1.65 trillion KRW. This highlights the strategic importance of Hyundai’s US production facilities in Georgia and Alabama. The industry will need to explore complex strategies including local price increases, incentive reductions, and expanding local production.

Steel and Aluminum: Unresolved Quota Issues

In 2018, Korea accepted a quota system limiting exports in exchange for exemption from 25% steel tariffs. However, this agreement risks being nullified. Worst-case scenarios include tariffs as high as 50%, creating greater uncertainty for the steel industry.

Agriculture: Two Conflicting Narratives

The biggest controversy is the opening of the agricultural market. President Trump announced that Korea would “completely OPEN” its agricultural market to the US, but the Korean presidential office firmly denied any additional opening of sensitive products like rice and beef.

This divergence appears to be a deliberate ambiguity strategy used by both governments for domestic political purposes. Although rice and beef protections remain, the issue of non-tariff barriers remains open, keeping agriculture a potential flashpoint.

Strategic Growth Industries: Semiconductors and Biotech

Fortunately, the agreement includes provisions guaranteeing Most-Favored-Nation (MFN) treatment for advanced industries like semiconductors and pharmaceuticals. MFN means granting the most favorable trade terms given to any country to all members equally. While it does not guarantee zero tariffs, it promises no worse tariff conditions than competitors, providing an important safeguard for our future growth industries.

Analyzing the $350 Billion Investment Mystery

The $350 billion investment commitment, the price of this negotiation, raises many questions. I recall being surprised by the scale and conditions when I first heard the news.

Structure, Control, and the ‘90-10’ Profit Distribution Controversy

The biggest controversy is Commerce Secretary Howard Lutnick’s statement that “90% of investment returns will go to Americans.” Our government strongly refuted this, saying it is not a 90% forfeiture but a reinvestment concept. This conflicting interpretation shows that intense tug-of-war over fund management has already begun.

$150 Billion Shipbuilding Cooperation Fund: A Strategic Lever

Of the total $350 billion, a remarkable $150 billion is designated as a ‘shipbuilding cooperation fund.’ This is notable because Korea provides capital and technology to help rebuild the US shipbuilding industry, and in return, Korean companies gain access to the US market, which has been protected by strong trade barriers like the Jones Act. This quid-pro-quo could become a new foothold for Korea’s world-class shipbuilding industry.

Comparing the US-Korea Trade Agreement with Other Countries

The $350 billion commitment corresponds to about 19% of Korea’s GDP, an enormous scale. How does this compare with other countries that recently concluded agreements with the US?

Table 3: Recent US Trade Agreement Comparison (Korea, Japan, EU)

The government explained that the fund structure is ‘guarantee-centered,’ so the actual burden is less, and excluding the shipbuilding fund led by Korea, the real investment scale is about 36% of Japan’s. Still, it is difficult to avoid the assessment that Korea bears a relatively large burden compared to its economic size.

Conclusion: The Start of a New Negotiation

The 2025 US-Korea Trade Agreement marks a major turning point for our economy and alliance.

• Costs: Loss of preferential FTA status and an astronomical $350 billion investment obligation.
• Benefits: Avoidance of a catastrophic 25% tariff scenario and groundwork for cooperation in shipbuilding and other sectors.
• Challenges: Ambiguous clauses on tariffs, investment fund governance, and agriculture suggest this agreement is not the end but the beginning of new negotiations.

In summary, Korea paid a high price for stability but also embedded strategic opportunities within the concessions. Now, the government and businesses must unite to develop concrete plans to leverage this strategic investment. Whether they can turn a defensive negotiation outcome into aggressive economic expansion will be the true test.
