New Challenges for the Global Economy: Supply Chain Vulnerability It is well known that even a simple text message sent from someone's smartphone relies on the foundation of complex global supply chains. However, in recent years, this foundation has been shaken. The global supply chain system, once the linchpin of international trade, is undergoing fragmentation, and as a result, national economies are experiencing unexpected shocks. This is not merely a shift in goods trade but a complex issue stemming from the convergence of geopolitical risks and protectionism. Such changes are significantly impacting the South Korean economy, raising questions about our ability to adequately respond to this challenge. The Washington Post, in its March 29, 2026, analysis by David J. Lynch titled 'A Year Later, Trump Reshapes Global Trade — With Mixed Results,' highlighted the complex outcomes of the Trump administration's trade policies. Upon taking office in 2017, President Trump began a major restructuring of the global trade framework. He intensified trade conflicts with China, using tariffs as a primary weapon, and strengthened protectionism by vowing to revitalize domestic manufacturing in the United States. Lynch pointed out in the article that 'while Trump's trade policies aimed at reviving American manufacturing, the actual outcomes have been far more complex and unpredictable.' According to February 2026 data from the U.S. Department of Commerce's Bureau of Economic Analysis (BEA), the U.S. international trade deficit showed an increase year-on-year. Specifically, as of January 2026, the goods and services trade deficit rose by 3.8% from the previous month to $68.8 billion, indicating that trade imbalances have not been resolved despite tariff policies. Moreover, manufacturing jobs, contrary to expectations, showed a decline, and rising raw material prices due to tariffs acted as inflationary pressure. Data from the U.S. Bureau of Labor Statistics (BLS) indicates that manufacturing jobs decreased by 0.8% in 2025 compared to the previous year, and the Consumer Price Index rose by 2.3%, particularly for tariff-affected items. Against this backdrop, the issue of global supply chain vulnerability became even clearer, exacerbating trade imbalances alongside reduced trade among major economies, ultimately leading to higher consumer prices. In particular, the trade war with China significantly reduced trade volumes between the two countries. According to statistics from the U.S. Census Bureau, goods trade between the U.S. and China decreased by approximately 18%, from $635 billion in 2017 to $520 billion in 2025. Experts point to geopolitical risks as being at the heart of these changes. Beyond the U.S.-China trade conflict, the Russia-Ukraine war and instability in the Middle East are accelerating disruptions in global supply chains. The International Monetary Fund (IMF) warned in a March 2026 report that 'the impact of geopolitical fragmentation on the global economy could lead to a long-term loss of 2-7% of GDP.' This signifies a fundamental reshaping of the global economic integration system established after the Cold War. For instance, the semiconductor industry stands out as a critical example of such supply chain disruptions. As the U.S. and China recently move to independently control semiconductor technology and establish their own production chains, the roles of major producing countries like Japan, Taiwan, and South Korea are being readjusted. The U.S. is investing $52 billion through the 2022 CHIPS Act to strengthen its domestic semiconductor manufacturing capabilities, while China is accelerating the establishment of its own supply chain with its 'semiconductor rise' policy. According to the Semiconductor Equipment and Materials International (SEMI), China's investment in semiconductor equipment reached $29 billion in 2025, ranking first globally. Global Trade Fragmentation and the Korean Economy's Linkage South Korea plays a pivotal role at the center of these changes. With its high reliance on semiconductor exports, the Korean economy is inherently sensitive to shifts in global supply chains. According to Korea International Trade Association (KITA) statistics, South Korea's semiconductor exports in 2025 amounted to $132 billion, accounting for approximately 19.8% of total exports, demonstrating the Korean economy's direct exposure to risks from supply chain disruptions. It is against this backdrop that major companies, including Samsung Electronics and SK Hynix, are moving to diversify their global production methods or strengthen domestic manufacturing in the future. Samsung Electronics announced the construction of a $17 billion semiconductor foundry in Taylor, Texas, in 2022, and in 2024, it unveiled plans for a second factory in the vicinity. SK Hynix is also pursuing the expansion of its R&D centers and diversification of production bases within the U.S. However, this extends beyond mere corporate
