The trade war between major countries, especially between the United States and China, has had a significant impact on the global macro economy. This conflict has had a major influence on trade flows, investment and economic growth in various parts of the world. One of the main impacts of the trade war is a decline in global trade volume. When high tariffs are imposed on imported goods, the price of the goods tends to increase, leading to a reduction in demand. Export-dependent countries, such as Germany and Japan, feel this impact directly, as they lose market share to countries involved in trade wars. Second, the economic uncertainty created by the trade war has a negative impact on foreign investment. Investors, who tend to be risk averse, become hesitant to invest capital in an uncertain environment. This leads to a decline in foreign direct investment (FDI), which in turn affects innovation and long-term growth. The impact on currencies is also worth noting. When a trade war is prolonged, the currencies of the countries involved often experience volatility. This can cause inflation in countries with weak currencies, reducing people’s purchasing power and affecting domestic consumption. The industrial sector also experienced a bad impact. For example, the automotive industry in the US was forced to adjust their supply chains disrupted by tariffs. Many companies have been forced to raise prices or reduce workforce to maintain profitability, which has resulted in unemployment rates and economic slowdown. In addition, the trade war has resulted in changes in global investment flows. Some companies moved their production bases to countries not involved in the conflict, such as Vietnam and India. This phenomenon is known as “reshoring” or “nearshoring”, where companies look for more stable and investment-friendly locations. From a fiscal policy perspective, governments in many countries are trying to adapt to the situation. They may need to increase spending to support affected sectors, which could lead to a budget deficit. This puts additional pressure on global economic stability. The psychological impact should not be ignored either. A persistent sense of uncertainty can reduce consumer and business confidence. With this decline in confidence, people tend to delay spending and investment, which has a negative impact on economic growth in various countries. By outlining the various impacts of this trade war, it is clear that the shift in global economic dynamics is one of the biggest challenges faced today. All economic sectors, both local and international, need to adapt to face the rapid changes and increasing uncertainty resulting from this trade conflict.
