Strip away the talking points and what remains is a fundamental market reallocation: artificial intelligence infrastructure is consuming resources faster than global supply chains can produce them. Mitsui Kinzoku, arguably the biggest supplier of copper foil for printed circuit boards, has now made this reality unavoidable. The company recently sent a letter to its customers notifying them of a 12% USD price increase for all of its MicroThin copper foil products, set to come into effect in April 2026.
The fundamental question is whether this represents a temporary blip or a structural shift in how electronics are priced. The evidence points decisively toward the latter. On the London Metal Exchange, copper reached record territory in early January 2026, pushing above $13,300 per tonne, more than 20 per cent higher than the late 2025 average as stock tightness and strong industrial demand combined. The Mitsui Kinzoku letter says that current copper material prices, plus labour, have resulted in soaring manufacturing costs for its foil products, and the wider copper market has been pretty tumultuous in recent months.
Mitsui Kinzoku's move is not isolated. Mitsubishi Gas Chemical also announced a 30% price increase across a range of products, including its resin-coated copper foil offering. These are not marginal players flexing pricing power; they are market leaders signalling genuine cost pressures. Yet the copper foil story masks a deeper reality. Consider what is actually happening to global manufacturing capacity: demand from the AI industry has doubled copper foil consumption—yes, this is yet another challenging supply landscape you can at least partially blame on AI.
The counter-argument deserves serious consideration: manufacturing costs genuinely have risen. Raw material inflation is real; so is energy cost volatility. Suppliers did not invent these pressures. But if we accept that premise (and the evidence suggests we should), then the next question becomes uncomfortable. When supply of a critical commodity is finite and multiple industries are competing for it, who bears the cost?
The answer is becoming clear: consumers will, particularly those least able to absorb price increases. A 10% price increase of one of the key components will be noticeable in the case of entry-level motherboards that are not sold with hefty profit margins and retail for $100–$200. Premium products have margin cushion. Budget hardware has none.
The broader electronics market is already signalling distress. IDC sharply slashed its expectations for the PC and tablet markets, citing memory shortages, rising prices for 3D NAND, DRAM, and other components, and intensifying supply chain disruptions amid the AI sector boom, with global PC shipments expected to drop 11.3% in 2026 compared to 2025, a steep revision from the -2.4% decline projected in November 2025. "The era of bargain-priced PCs and tablets is behind us for now, as rising ASPs and component costs shift the market's balance of power," said Jitesh Ubrani, research manager for IDC's Worldwide Mobile Device Trackers.
Here lies the genuine tension in this story: unit volumes are collapsing, yet market revenue holds relatively steady. IDC estimates that the PC market will expand by 1.6% in value to $274 billion in 2026, while the tablet segment will grow by 3.9% to $66.8 billion. This is not neutral. It means fewer people can afford new computers, but those who do buy will pay significantly more. The economic outcome advantages incumbents and penalises entry-level consumers.
Is this outcome inevitable? Perhaps. AI computer hardware refreshes every 2–4 years—and in some cases every 18–24 months—while new glass yarn and copper foil capacity requires years to build, qualify, and stabilise, meaning supply and demand are unlikely to rebalance in the near term and the cadence of AI infrastructure investment is simply outpacing upstream capacity expansion. The math is unforgiving.
Voters and consumers deserve honest conversation about what this means. Memory shortages will persist well into 2027, while the market is unlikely to return to the pricing levels seen in 2025, instead defining a new normal with structurally higher average selling prices and corresponding softening in long-term demand. Vendors are already signalling tactics like offering systems without RAM or memory modules preinstalled, which amounts to asking customers to navigate sourcing complexity.
This is not a left-right issue; it is a competence and foresight issue. Whether policymakers should have anticipated that AI infrastructure buildout would create bottlenecks in commodity supply chains is a legitimate question. That it has happened is now indisputable. The copper foil price rises are merely the messenger revealing the shape of a market restructuring that has already occurred.
