The US trade deficit, at its core, is the result of the collision between two forces. One is that the industrial chain has long moved overseas, leading to a hollowing out of domestic manufacturing, with everyday consumer goods relying on imports to fill the gap. The second is the special status of the US dollar—serving as the world's primary reserve currency, the US can import goods at a lower cost. While this deficit may seem like a loss, it actually maintains the dollar's dominant position in international trade. From another perspective, this is a form of structural complementarity: the US has strong consumption capacity, while other countries are export-oriented, and both sides quickly find common ground. However, this imbalance also harbors hidden risks—trade tensions could escalate at any time, and the global industrial chain faces reconstruction pressures. No matter how strong the US economy is, it cannot bypass this hurdle.
