Multilayer ceramic capacitors (MLCCs) — postage-stamp-sized components critical for regulating electric currents in AI servers and electric vehicles — have surged two- to fourfold in price on the Shenzhen spot market since Chinese New Year 2026, as the global artificial intelligence buildout triggers a supply crunch that is rippling across electronics supply chains worldwide.

The component at the centre of the storm

Last year, memory chips were the scarcest commodity in Shenzhen's Huaqiangbei electronics market. In 2026, that distinction belongs to the MLCC. These minuscule passive components store and discharge electrical energy, making them indispensable for the power-hungry processors that underpin modern AI server clusters. Global manufacturing lines are scrambling to secure adequate supply as demand outstrips production capacity.

A distributor surnamed Wu, who primarily sells components from Japanese industry leader Murata Manufacturing to fellow traders and secondary distributors, confirmed that high-capacitance MLCCs — those designed to support the most demanding power loads — are at the epicentre of the price surge. 'I don't see any signs of prices cooling down,' Wu said.

Why it matters

MLCCs are among the most ubiquitous electronic components on the planet, used in everything from smartphones to industrial machinery. When their prices spike, the cost pressure cascades through virtually every hardware category. The current squeeze is being driven simultaneously by two of the most capital-intensive technology transitions of the decade: the AI infrastructure buildout and the global shift to electric vehicles.

According to Wu, some MLCC models have jumped from 10 yuan per 1,000 units to 40 yuan (US$5.90) — a 300% increase. The price hikes are not confined to high-capacitance variants; the spot market is seeing broad-based inflation across multiple MLCC categories.

Market reaction

Despite a flood of purchase inquiries at Huaqiangbei, actual transaction volumes remain subdued, according to Wu. Buyers are reportedly balking at the steep price tags, creating a standoff between sellers holding elevated inventory valuations and purchasers unwilling to lock in costs at cycle highs. This buyer hesitation is a classic feature of commodity spot markets during rapid price discovery phases.

Chinese MLCC vendors are the immediate beneficiaries, riding what distributors describe as a massive demand wave. Yet the supply side faces structural constraints: expanding MLCC manufacturing capacity requires significant lead times, meaning relief is unlikely to arrive quickly.

The competitive backdrop

Murata Manufacturing of Japan remains the global market leader in MLCCs, but Chinese domestic producers have been steadily expanding their share of the mid-tier market. The current price environment may accelerate investment in domestic Chinese MLCC capacity, echoing the pattern seen in memory chips and solar panels in prior commodity cycles.

Analysts have noted that AI server bills of materials are increasingly sensitive to passive component costs as GPU cluster densities rise, meaning sustained MLCC inflation could modestly pressure data centre capex budgets globally.

What's next

With Wu and other distributors seeing no near-term price relief, procurement teams at server manufacturers and EV makers face a difficult choice: absorb higher component costs or delay builds. The trajectory of MLCC prices in Shenzhen's spot market over the coming months will serve as an early indicator of whether the broader AI hardware supply chain is tightening further or beginning to rebalance.
