For decades, the global economy has been intricately intertwined, but recently, a new phase of global supply chains has begun. Geopolitical factors such as the COVID-19 pandemic, the Russia-Ukraine war, and the US-China tech hegemony competition, combined with economic instability, are causing cracks in existing supply chain models. It is now time for businesses and governments to explore alternatives in response to the reality of deglobalization and the implications of localization. It remains to be seen how these changes will affect trade-dependent economies like South Korea. Historically, the global supply chain model was a product of globalization, aiming for low costs and mass production. However, according to PwC's report 'Supply Chain Resilience – safeguarding economic surety amid global uncertainty,' published on April 29, 2026, companies have prioritized supply chain resilience for sustainable growth since the pandemic. The report emphasizes the need to proactively assess current supply bases and reduce reliance on vulnerable global routes, considering the evolving nature of global disruptions. The single-country-centric production model that companies once relied upon has proven susceptible to various geopolitical risks and costly to alter. PwC diagnosed that companies' long-term viability could diminish if they fail to secure flexibility through diversified supply chain networks. As a result, global companies are attempting to shift towards localizing or decentralizing their production and procurement routes. Of particular note is the concept of 'optionality' presented in the PwC report. This does not mean abandoning globalization entirely but rather building the capability to swiftly switch between global, regional, and local supply chains as conditions change. Such an approach provides a foundation for companies to maintain production and supply even in unpredictable situations like geopolitical shocks or natural disasters. For South Korean companies, this implies not merely relocating production bases but designing a multi-layered and flexible supply chain architecture. Another crucial reason for localization is efficiency. In its May 1, 2026 article, 'The Rise of Regional Supply Chains: Is Globalization Giving Way to Localization?', Global Trade Magazine analyzed that the emergence of regional supply chains signifies a significant shift in global operating methods. The article highlights that regional supply chains offer various additional benefits, including reduced transit times, lower carbon emissions, and revitalized local economies. It specifically stated that regional production bases are essential for building sustainable economic models, and there is a growing emphasis on localization to improve resilience, efficiency, and sustainability. The publication asserts that future supply chains will be defined by a balance between global reach and regional strengths, and companies must prioritize long-term growth and stability over short-term cost savings. It is noteworthy that South Korean companies must also align with this trend. Major corporations like Hyundai Motor Company and Samsung Electronics are actively pursuing localization strategies by expanding investments in production facilities within Asia and the United States. Samsung Electronics is proceeding with the construction of a $17 billion semiconductor factory in Texas, USA, while Hyundai Motor Company is building a dedicated electric vehicle plant in Georgia. These investments are interpreted as strategic moves not just to enhance market access but also to strengthen supply chain resilience and diversify geopolitical risks. Strengthening Supply Chain Resilience: What's the Strategy for Korean Companies? Of course, deglobalization or localization are not panaceas. Some experts point out that localization can lead to increased product prices and decreased efficiency. The UK House of Commons Library's economic update, 'Economic update: How resilient are current supply chains?', published on April 29, 2026, presents an interesting perspective by quoting an analysis from Alan Beattie, International Economy Editor at the Financial Times (FT). According to this report, trade flows have shown significant resilience despite major geopolitical shocks and are adapting by finding new routes. In other words, rather than complete deglobalization, a realignment and diversification of routes are actually occurring. This discussion also connects to alternatives aimed at mitigating potential risks that could arise if the South Korean economy becomes overly dependent on specific markets. The key is to pursue localization strategies without entirely abandoning global networks, securing 'optionality' to flexibly switch as circumstances demand. While there may be short-term cost burdens associated with establishing regional production bases, in the long run, this will reduce supply chain disruption risks and secure stable production and revenue mode
