From Globalization to Fragmentation: The Three-Bloc Battle for Power

By Ian Kim '27  • Nov 10, 2025

Tripolar fragmentation: The global economy increasingly split between the United States, China, and the European Union, as trade lines weaken across blocs.

The global economy is shifting towards a fragmented structure where nations tightly align with one of three blocs: China, the European Union, or the United States. This tripolar framework has more severe consequences than the U.S.-China divide, since economic ties weaken across all three blocs simultaneously. In the downside bipolar case, global GDP could contract by 5.5%, but under tripolar fragmentation, the potential loss rises to 8.4%. 

China has hit the hardest due to its dependency on U.S trade, and consumer demand accounts for a 3.24 percentage point drop in its global output. On the other hand, the U.S bloc loses 2.89 points, with the EU bloc following 2.27. Despite this, the European Union is in an incomparable economic vulnerability, as its prosperity depends heavily on trade with both the United States and China. Losing connections to partners in both blobs could possibly reduce the EU output by as much as 13.3% of GDP; even larger contractions could happen than China’s 12.5% loss in the bipolar world. 

The structural role of the U.S in global consumption reinforces these risks since exemption from the U.S markets severely affects both EU and Chinese growth. For example, China alone would lose 9.2 percentage points of GDP if its access to the U.S is denied. In conclusion, these structural dynamics suggest that the tripolar trade fragmentation would not only slow down the speed of global growth but also become a barrier to a stabilized and advanced economy.  

The United States is transitioning from a global supply chain shared with China to an independent U.S.-led system that helps strengthen domestic production and reduce reliance on global resources. The United States is making significant investments in vital resources like minerals, semiconductors, and logistics in order to achieve this. In addition to creating supply agreements with nations like Saudi Arabia and Ukraine, this has aided in the implementation of laws like the Defense Production Act and the CHIPS Act. The United States has established relationships with allies, including Taiwan, Japan, and Korea, in the semiconductor industry. It has improved manufacturing independence and stabilized supply by strengthening the CHIP Alliance. With initiatives like Hanwha demonstrating global ties within corporations and extended strategies, the U.S. reshoring movement from 2022 to 2025 has concentrated on constructing manufacturing plants and extending energy infrastructure.

Overall, the United States’ strategic shift towards an independent supply chain reflects a broader shift towards economic fragmentation and reliance. While this change may help strengthen the domestic industries and connected alliances with cooperations, it continuously deepens the gap among the world's three major blocs. The declining interdependency of countries like China and the EU is faced with the competition for resources. The economy will have to face limitations with its long-term consistency and innovation cycle. In conclusion, these realignments reveal the eagerness and pursuit of economic safety, blinding the expenses of global cooperation.
