The trade war, especially between the United States and China, has had a significant impact on the world macro economy. The dispute is fueling uncertainty in global markets, affecting economic growth and shaking up international supply chains. In this context, here are some of the main visible impacts of the trade war. One of the most obvious impacts is the decline in international trade. Tariffs imposed by both countries cause the cost of imported goods to increase. For example, the ratio of global trade to gross domestic product (GDP) for many countries has decreased, slowing global economic growth. This impacts small countries that depend on exports, causing stagnation or decline in their economic growth. Furthermore, investors tend to shift their investments to safer assets during uncertainty due to trade wars, resulting in stock market fluctuations. Shares of companies with large exposure to international trade often experience volatility. This places additional burdens on companies that depend on market stability for growth. These companies are forced to reorganize their business strategies and reevaluate supply chains to avoid high tariffs. Another impact is on inflation. Increased tariffs on imported goods are often passed on to consumers in the form of higher prices. For example, the prices of electronic goods produced in China are increasing, which is causing inflation to rise in destination countries such as the US. This disrupts consumer purchasing power which ultimately reduces aggregate demand. Certain industries have also been significantly impacted. For example, the agricultural sector in the United States felt a direct impact through a decrease in exports to China, which is one of the largest markets for agricultural products. This has implications for farmers’ income and can result in bankruptcy among small farmers. Trade wars also encourage countries to look for alternatives in trade cooperation, turning to new partners or strengthening regional trade agreements. For example, several Southeast Asian countries are seeking to increase intra-regional trade to reduce dependence on the United States and China. On the investment side, multinational companies responded by moving their production from China to other countries such as Vietnam and India. This signals a major change in the global production map, which could have a long-term impact on the economic development of these countries. In the short term, a trade war could increase the risk of recession in some major economies. Countries with a high dependence on exports also face a greater threat of stagnation. More expensive credit and rising production costs will discourage new investment, and global economic growth could be further depressed as a result. Overall, the impact of the trade war on the world macro economy has created a detrimental domino effect. The resulting uncertainty has the potential to slow innovation and long-term growth. To face this challenge, international collaboration and constructive dialogue are very necessary to avoid being trapped in conflicts that worsen the global economic situation.
