The Cost of Western De-Sinicization: An Estimated $23.6 Trillion
0xBroomberg
EY-Parthenon estimates the US and Europe would need an extra $23.6 trillion by 2050 to end reliance on China in key industries — putting a concrete price tag on what has so far been mostly political rhetoric.
How does the $23.6 trillion break down?
By country: the US accounts for $13.7 trillion, the eurozone $9.1 trillion, and the UK $800 billion, all through 2050.
In annual terms, the US would need roughly $550 billion a year — This means → an outlay comparable to what Big Tech is spending on data centers in 2025 alone ($600 billion).
The EU faces an even steeper hill: its required annual spend would approach twice its current annual budget. In plain terms = Brussels would need to conjure an entire second budget from thin air.
Is $940 billion a year actually affordable?
EY-Parthenon says the combined annual bill of $940 billion is "not insurmountable" in theory.
But the money must come on top of existing commitments to energy, defence, and infrastructure — it is pure additional spend, not a reallocation.
This means → the burden starts small but compounds over time; the further in, the heavier the fiscal strain.
Why can't money alone guarantee decoupling?
Alicia García-Herrero, BNP Paribas's chief Asia-Pacific economist, argues the challenge is not just cost — China can actively disrupt the decoupling process itself.
From rare-earth processing to active pharmaceutical ingredients — the chemical building blocks of medicines — China's grip on critical supply chains gives it real retaliatory leverage.
In plain terms = decoupling is not a one-sided decision. If the West tries to cut China off, China can cut the West off right back.
How deep does China's supply-chain control run?
IEA data: by 2035, China is expected to supply over 60% of the world's refined lithium and cobalt and roughly 80% of battery-grade graphite and rare-earth elements.
These are the core materials for the clean-energy transition — EVs, wind, solar. This reflects a fundamental tension: the West's green strategy and its decoupling strategy pull in opposite directions.
Last year, Beijing imposed export controls on key rare earths; US and European car production lines nearly shut down until a trade truce was reached — an episode that accelerated the EU's push to build strategic rare-earth reserves.
How much would decoupling raise prices?
Chinese-made goods typically carry a 20–100% factory-gate price advantage — reducing reliance means switching to costlier alternatives.
In Europe, severing dependence on China could push prices in key sectors up by 1–2.5% and keep the ECB and the Bank of England persistently above their 2% inflation targets.
This means → the cost of decoupling ultimately lands on consumers and taxpayers, in the form of higher prices and tighter monetary policy.
What is the realistic path forward?
EY-Parthenon partner Mats Persson, a former Downing Street adviser, calls localising supply chains without excessive cost to taxpayers "one of the toughest challenges of the coming years."
Given the scale, partial decoupling is more realistic than a full break — firms need to deploy capital selectively.
In plain terms = the goal is not to reshore everything, but to identify the critical chokepoints where China could cut access — and spend the money there first.
