President Trump has once again played the protectionist card. This time, the automobile and semiconductor industries are directly targeted, raising global tensions.
He has suggested the possibility of imposing automobile tariffs starting on April 2, citing the protection of domestic industries as a justification. However, opinions are divided on whether this measure will have a positive impact on the U.S. economy. Will this policy serve as an opportunity to revitalize American manufacturing, or will it become an additional burden on the global economy?

Trump’s Protectionism: Is the Automotive Industry Taking the Biggest Hit?
The Trump administration has previously imposed tariffs on steel, aluminum, and Chinese products, disrupting the global trade order. This latest measure is not just a trade policy; it has the potential to shake the very structure of the automotive industry. Modern automobile production is based on a global supply chain, meaning that if parts from Mexico or Canada are not available, factory operations in the U.S. may come to a halt. Experts warn that if this measure is prolonged, American automobile factories could shut down within a short period.
The U.S. automotive industry argues that this policy could backfire. Tariffs would disrupt the supply of parts, increase production costs, and ultimately lead to higher consumer prices. As a result, American consumers would have to pay more for their vehicles, potentially leading to decreased sales. Additionally, workforce reductions and a rise in unemployment within the U.S. automotive industry could become inevitable. If this scenario unfolds, the “America First” policy pursued by the Trump administration may ultimately undermine the competitiveness of domestic industries.
Furthermore, this tariff policy could nullify the effects of the existing United States-Mexico-Canada Agreement (USMCA). The USMCA provides duty-free benefits for specific parts produced within North America, but if Trump’s new tariff policy is implemented, its effectiveness may be significantly diminished.

South Korea’s Automotive Industry: An Opportunity or a Crisis?
What impact will this have on the South Korean automotive industry? If production costs in the U.S. surge, imported vehicles from South Korea, Japan, and Europe may become more competitive. As a result, American consumers might favor imported cars, potentially benefiting South Korean automakers. However, increasing pressure from the U.S. could necessitate further trade negotiations. Companies like Hyundai and Kia must prepare thorough strategies in response.
Stakeholders in the South Korean automotive industry are considering new strategies to maintain their competitiveness in the U.S. market. Some experts suggest expanding local factories or increasing local production of parts, while others recommend differentiation strategies such as premium models and eco-friendly vehicles to attract American consumers. However, if the U.S. enacts additional protectionist measures, the burden on the South Korean automotive industry will only grow.
Will the Semiconductor Industry Be Targeted as Well?
Following the automotive sector, President Trump has also mentioned semiconductors as another key industry under consideration. Until now, semiconductors have been traded globally without tariffs, but he is contemplating the introduction of “semiconductor tariffs.” This move is not just about industrial protection—it is also interpreted as a strategic measure to curb China’s growing semiconductor sector. The issue is that major semiconductor producers such as South Korea, Taiwan, and Japan will inevitably be affected.
The semiconductor industry is even more dependent on the global supply chain than the automotive industry, making it difficult for any single country to independently increase production. If the U.S. imposes semiconductor tariffs, semiconductor prices could rise sharply, which would, in turn, impact the cost of final products. Since semiconductors are essential components in most advanced technologies, including smartphones, computers, and electronic devices, consumers would ultimately bear the increased costs.
Moreover, South Korean and Taiwanese semiconductor companies will need to reassess their sales strategies for the U.S. market. Currently, global semiconductor leaders include South Korea’s Samsung Electronics and SK Hynix, as well as Taiwan’s TSMC. If the U.S. imposes tariffs, domestic American semiconductor companies might benefit. However, experts argue that it will be difficult for U.S. semiconductor manufacturers to immediately replace their foreign competitors, making short-term disruptions inevitable.
What Lies Ahead?
If Trump’s tariff policy is implemented, it may have unintended consequences, negatively impacting the automotive and semiconductor industries rather than protecting them. The U.S. automotive industry is likely to be hit hard, and global supply chains could be severely disrupted. Major exporting countries, including South Korea, must strengthen their response strategies and consider taking the issue to the World Trade Organization (WTO).
Moreover, the impact of Trump’s latest measure may extend beyond the automotive and semiconductor industries. If protectionist policies continue to expand into other sectors, the overall international trade environment could undergo significant changes. Governments and businesses worldwide must carefully analyze the long-term consequences of these tariff policies and prepare appropriate countermeasures.
What will be the long-term outcome of Trump’s policy? How the automotive and semiconductor industries respond will be a crucial factor in shaping the future economic landscape.
