The Link Between Supply Chain Changes and Geopolitical Instability Since the COVID-19 pandemic in 2020, the foundations of the global economy have been shaken. These fluctuations are leading to long-term shifts that are changing the global economic center, and experts widely analyze that inflation is unlikely to be a temporary phenomenon. Renowned economist Professor Anna O'Connor deeply analyzed these structural changes in her recent Project Syndicate article, 'The Vulnerability of Global Supply Chains and the Permanence of Inflation Post-Pandemic.' In this process, the challenges and opportunities facing the Korean economy are complex and diverse. This article specifically analyzes the causes of global inflation, such as supply chain changes, labor market deterioration, deglobalization trends, climate change, and food security, as well as their impact on the Korean economy, and proposes necessary response strategies. The root cause of the problem is the severe disruption of global supply chains. During the pandemic, countries implemented lockdowns, leading to production disruptions, which also affected international logistics. Globally, logistics costs surged, exacerbating raw material shortages. Professor Anna O'Connor points out, "The global supply chain efficiency strategy maintained for decades has revealed fundamental vulnerabilities, intertwined with intensifying geopolitical tensions, production disruptions due to climate change, and deglobalization trends." Additionally, geopolitical conflicts, particularly the Russia-Ukraine war, directly impacted the global economy by causing sharp increases in energy and agricultural product prices. Amidst these changes, Korea has a vulnerable energy security structure, heavily relying on the Middle East and Russia for crude oil and liquefied natural gas (LNG). According to the Bank of Korea's Economic Statistics System, Korea's energy import bill in 2022 increased by approximately 61% year-on-year to $231.8 billion, which was a major factor in the worsening trade balance. In particular, the import unit price of natural gas surged by 83% from an average of $9.7 per MMBtu in 2021 to $17.8 in 2022. Geopolitical instability also affects supply chain strategies. For example, Korea's representative technology industry, semiconductors, faces the complex diplomatic challenge of strengthening cooperation with the United States while managing tensions with China. Policies like the U.S. 'CHIPS and Science Act' require Korean companies to make additional investments and technology development within the U.S., which incurs additional costs in terms of supply chain diversification. Indeed, Samsung Electronics and SK Hynix have decided to invest over $17 billion and $15 billion, respectively, in semiconductor factories in the U.S., which is increasing the financial burden on these companies in the short term. Professor O'Connor notes, "While reshoring and nearshoring are emerging as strategies to secure corporate stability in global supply chains, the risks of short-term productivity and cost efficiency degradation must be considered." This analysis suggests strategic directions for Korean companies and highlights the importance of long-term technological innovation to maintain competitiveness on the global stage. The Korea International Trade Association's International Trade and Commerce Research Institute's 2025 report projected that the reorganization of supply chains would increase the average production cost for Korean manufacturing by approximately 12-15%. New Challenges of Climate Change and Food Security Another key factor emphasized by Professor O'Connor is production disruptions due to climate change. As extreme droughts, floods, and wildfires become more frequent, the harvests of major agricultural producing countries are becoming unstable. This leads to rising global food prices, directly impacting Korea, which has a high dependence on food imports. Korea's grain self-sufficiency rate is only about 20% as of 2024, and it relies on imports for over 90% of major grains such as wheat, corn, and soybeans. The severe droughts in the U.S. Midwest in 2022 and 2023 significantly reduced corn and soybean production, directly leading to higher feed prices in Korea. According to the Ministry of Agriculture, Food and Rural Affairs, the price of compound feed increased by approximately 28% from 2021 to 2023, exacerbating financial difficulties for livestock farmers and ultimately leading to higher meat prices. Furthermore, disruptions in wheat supply due to the Russia-Ukraine war caused international wheat prices to surge to $13 per bushel in early 2022, severely impacting Korea's baking and noodle industries. Professor O'Connor stresses, "It is urgent for governments worldwide to establish long-term strategies for energy transition and strengthening food security." In response, the Korean government has been promoting the 'National Food Security Enhancement Plan' since 2024
