The $24 Trillion Divorce: Why Decoupling From China Is a Costly, Uphill Battle for the West

As the Trump administration accelerates its campaign to unwind decades of economic integration with Beijing, a sobering reality is beginning to set in: the price of independence may be higher than any Western government is currently prepared to pay. While the political rhetoric surrounding “decoupling” has reached a fever pitch, a new analysis suggests that the structural shift required to actually achieve it would require a generational investment on a scale rarely seen in peacetime.

According to a comprehensive study by EY-Parthenon, the U.S., the Eurozone, and the UK would need to collectively mobilize an additional $23.6 trillion over the next 25 years to effectively end their reliance on China in highly exposed sectors. The burden falls most heavily on Washington; the U.S. alone would need to funnel $13.7 trillion into its domestic economy—a sum exceeding half of the total requirement. This capital would not merely go toward building new factories, but would need to be distributed across a massive overhaul of national infrastructure, research and development, manufacturing capacity, software systems, transportation networks, and intensive workforce training.

The urgency of this financial reckoning comes as President Donald Trump intensifies efforts to squeeze Chinese imports out of the American market. His administration has moved to implement a 10% import tax under Section 122, a measure set to expire later this month, alongside a more aggressive suite of levies ranging from 7.5% to 100% under Section 301. These latter duties, designed to combat alleged unfair trade practices such as forced labor, represent a significant escalation of a protectionist trend that began during Trump’s first term and continued under the Biden administration through initiatives like the CHIPS Act, which sought to reshore the critical semiconductor industry.

Despite these legislative hurdles, the umbilical cord between the world’s two largest economies remains remarkably resilient. The U.S. currently consumes 14% of all Chinese exports. While that figure has retreated from the 20% seen in 2017, the granular data reveals a deep-seated dependency in consumer electronics and household goods. According to the United Nations Comtrade database, the U.S. sourced 45% of its smartphone and telephone equipment—valued at $51.5 billion—and a staggering 76% of its toys, worth $14.4 billion, from China in 2024. Far from cooling off, China’s export engine has recently found a second wind; last month, export growth surged 27% from a year earlier, a sharp recovery from the double-digit year-over-year declines seen throughout much of the previous year.

Mats Persson, the macro and geostrategy leader at EY-Parthenon UK, describes these figures as a wake-up call for policymakers attempting to navigate a globalized world with a protectionist compass. “You have this dynamic, this dialect between these two forces, which has always been there for many hundreds of years in one way or another, but which is now so pronounced,” Persson told Fortune. He notes that while localization efforts—such as the push for domestic manufacturing and bans on high-end AI hardware—provide a safety net during geopolitical crises, they often clash with the fundamental corporate drive for economic expansion, which has long been fueled by the low labor and manufacturing costs found in overseas markets.

The economic friction of moving production back to Western shores is perhaps the most significant hurdle. Chinese factory prices for certain components remain between 20% and 100% lower than their Western counterparts, a result of decades spent building unmatched production scale and supply chain density. For the U.S. to replicate these ecosystems from scratch, Persson warns that inflation would become structurally higher, likely adding 1% to 2% to the baseline cost of living.

To manage these price pressures, Persson suggests the U.S. would essentially need to implement the equivalent of an Inflation Reduction Act every single year. The landmark 2022 law, which directed roughly $891 billion toward clean energy, healthcare, and deficit reduction, was considered a once-in-a-generation piece of legislation; repeating it annually would be a fiscal feat of unprecedented proportions. In Europe, the situation is even more dire. EY-Parthenon estimates that if the European Union attempted to fund these supply-chain and infrastructure shifts through taxpayer resources, the EU budget would effectively have to double.

“We’re not going to achieve these levels of investments,” Persson stated bluntly.

However, the outlook is not entirely bleak for the West, particularly for the United States. Persson argues that the U.S. is better positioned for a localization push than Europe, thanks to the sheer depth of its capital markets, the status of the U.S. dollar as the global reserve currency, and a higher degree of energy independence. Yet, even with these advantages, the U.S. remains tethered to Beijing for critical minerals that are essential for the very semiconductor supply chains it hopes to insulate. Furthermore, the U.S. faces a looming human capital crisis; a persistent skills gap in manufacturing, exacerbated by decades of offshoring, means an estimated 2.1 million manufacturing jobs may go unfilled by 2030, according to data from Deloitte and The Manufacturing Institute.

The challenge is compounded by China’s own strategic advantages. Beijing’s long-term industrial policies have created a system that is incredibly efficient and capable of making decisions based on multi-decade cycles. In contrast, the EU must navigate the competing interests and democratic processes of its 27-member coalition, often leading to slower, more fragmented policy responses.

History suggests that trade patterns can shift abruptly under duress, though rarely without pain. Before Russia was expelled from the G8 in 2014 following the annexation of Crimea, large swaths of Europe were inextricably linked to Russian energy. The subsequent invasion of Ukraine forced a hard pivot, driving Russia into closer trade partnerships with China and India. This serves as a reminder that while governments can influence trade, massive supply chain shifts are often dictated by external shocks beyond any single country’s control.

Looking ahead, the era of hyper-globalization may be over, but a total retreat into isolationism appears equally unlikely. “It’s very hard to see a world in which we go back to that level of globalization within the next couple of decades, nor do I think this is in the way the end of globalization,” Persson said. Instead, he anticipates a future defined by a “messy, non-linear type of globalization,” where trade routes are constantly redrawn by a volatile mix of national security concerns and economic necessity.
