The recent tariff policies imposed by the United States have triggered global trade shocks. Starting from May 2025, the U.S. will impose a 25% tariff on imported cars and auto parts, leading to a risk of export decline and supply chain disruptions in the South Korean automotive industry, prompting companies like Hyundai and Kia to accelerate local production in the U.S. China has taken countermeasures, imposing a 15% tariff on U.S. coal and liquefied natural gas, while increasing the import tax rate on agricultural products to 27%. Countries such as the European Union and Mexico also face tariff pressures on steel, aluminum, and agricultural products. European ports like Hamburg are experiencing cargo delays due to intensified logistics congestion. Data shows that the U.S. inflation rate has shown an upward trend due to tariff pass-through, with the core CPI in May reaching a four-month high in month-on-month growth. Economists warn that the cost of tariffs will ultimately be passed on to American consumers, with an expected increase in annual household spending of $4,400. This unilateral policy not only impacts the global supply chain but also traps the U.S. itself in a dual dilemma of expanding trade deficits and uncontrolled inflation.
