What Happens When China's Export Machine Runs Out of Customers

China posted a $1.2 trillion trade surplus in 2025, the largest in recorded history, growing three times faster than global goods trade. That's not a flex. That's a structural problem that's about to break something.

Michael Froman, former U.S. Trade Representative and current president of the Council on Foreign Relations, put it plainly in Foreign Affairs last month: "The world's ability to absorb Chinese overcapacity is approaching a breaking point." The math doesn't work anymore. Global GDP growth is running around 3.1% this year, while China's trade surplus expanded more than 20% in early 2026. You can't grow exports that much faster than the global economy can grow demand. Eventually you run out of road.

This isn't just about tariffs or Trump's trade war, though that's part of the story. It's about what happens when an export-led growth model built on state subsidies, an undervalued currency, and industrial overcapacity hits the limit of global demand. And according to Froman and a growing number of economists, we're getting close to that limit.

Chinese companies charge as much as 30% less than competitors in other parts of the world. State subsidies and mandates from Beijing have encouraged excess production and cutthroat price wars, forcing companies to turn to export markets just to stay alive. Nearly a third of Chinese industrial firms are operating at a loss right now.

The result is an industrial machine that can't stop and can't slow down, but that's running into the limits of demand. China alone has the capacity to produce two-thirds of the world's demand for cars, according to Brad Setser, a former Treasury official. China also makes more than half the world's supply of steel, aluminum, and ships.

Meanwhile, imports of manufactured goods into China have grown by an average of just $15 billion annually over the last six years, essentially flat after accounting for inflation. But exports from China have shot up by more than $150 billion. That's a one-way street, and the rest of the world is starting to notice.

Federal Reserve economists wrote a note in May calling this "China Shock 2.0," and the distinction matters. The first China shock in the early 2000s was driven by labor-intensive goods like textiles and furniture. This one is driven by capital- and tech-intensive industries like electric vehicles, semiconductors, and advanced manufacturing.

That's a different kind of disruption. Advanced economies expected to dominate those sectors domestically. Now they're getting undercut by Chinese producers with massive state backing and operating margins that don't need to make sense. Apollo's chief economist Torsten Slok made this point last month: China is increasingly exporting the kinds of products that advanced economies once thought they'd own.

The political response is already playing out. Trump hiked tariffs on China and made it the centerpiece of his "Liberation Day" trade war. But even the European Union, which has historically defended open markets, is racing to put up trade barriers against Chinese imports. Froman's read on this is straightforward: "The political appetite for accepting the deindustrialization and critical dependencies that come with the flood of Chinese imports is finite and shrinking."

Beijing has acknowledged it needs to rebalance away from exports and support consumer spending. The government is also trying to crack down on what they call "involution," or over-competition. But Froman's argument is that China can't fully commit to abandoning the export-led growth model, because it's not just an economic strategy. It's a political project.

So what happens if protectionism suddenly closes off China's access to a broad swath of foreign markets? Froman lays out the cascade: already-fragile businesses fail en masse, state-owned banks record losses on "zombie firms," cascading defaults in local government financing vehicles, and provincial revenues collapse.

That's the domestic fallout. But China's demand for raw materials and intermediate goods would dry up at the same time, hitting commodity-exporting economies and other developing countries that depend on China as a top trading partner. Australia, Brazil, Southeast Asia—all of them would feel it.

Setser's warning last year was that China's flood of exports could pose the worst threat to the global economy, even eclipsing Trump's tariffs. His point was that this creates a world economy where China has no need for the industrial inputs of other countries while leaving those countries dependent on Chinese-made goods. That's not a stable equilibrium. That's a dependency trap.

Froman's closing argument is the uncomfortable part: even if the next crisis is made in China, the cleanup is likely to fall on the United States and the institutions it anchors. Beijing has shown little interest in taking on the role the U.S. plays in the global economy as a stabilizer and lender of last resort.

That means if this breaks, the Federal Reserve, the Treasury, and the IMF are probably the ones who end up managing the fallout. Not because they caused it, but because there's no one else positioned to do it. Similar to how geopolitical shocks create asymmetric market responses, this would be a crisis where the structural response doesn't match the structural cause.

The timeline on this is unclear. China's government is trying to thread the needle between reform and maintaining control. Other countries are trying to stem the flow of Chinese exports without triggering a trade war that makes everything worse. But the math is converging toward a breaking point, and understanding behavioral responses to structural pressures matters when you're trying to read how markets will react.

A few specific things to track if you're trying to gauge where this goes:

China's monthly trade surplus data. If it keeps expanding at 20%+ while global GDP growth stays around 3%, the gap widens. If it starts to flatten or contract, that tells you either demand is drying up or Beijing is managing the slowdown.

European and U.S. trade policy. New tariffs, anti-dumping measures, or regulatory barriers aimed at Chinese imports signal the "political appetite" Froman mentioned is shrinking faster than expected.

Commodity prices, especially industrial metals and energy. If China's demand for raw materials starts to drop, you'll see it in copper, iron ore, and crude oil before you see it in headline GDP numbers.

Chinese local government financing vehicles (LGFVs). These are the entities that borrowed heavily to fund infrastructure and industrial projects. If defaults start cascading, that's the early warning system for the domestic crisis Froman described.

The structural read here is that this is a slow-moving pressure system, not a sudden shock. But slow-moving doesn't mean low-impact. The question is whether the adjustments happen gradually through policy and market forces, or whether something breaks and forces a disorderly adjustment. Right now, the setup looks more like the latter.
