Chinese MLCC stocks surge 180% as AI data centre demand hits five-year high
Synopsis
Key Takeaways
China's multilayer ceramic capacitor (MLCC) sector is experiencing a dramatic stock rally driven by surging first-half earnings, as the global buildout of artificial intelligence infrastructure pushes demand for these critical electronic components to multi-year highs. Shares of leading domestic producers hit exchange-imposed daily limits on Wednesday, 29 July 2026, extending gains that have already topped 180 per cent for some names this year.
The rally in numbers
Guangdong Fenghua Advanced Technology, one of China's foremost producers of consumer-grade MLCCs and listed on the Shenzhen exchange, hit the bourse's 10 per cent daily limit on Wednesday — the second time this week it reached the ceiling — capping a year-to-date gain of more than 180 per cent. Suzhou GYZ Electronic Technology jumped 20 per cent to its daily limit on Shanghai's Nasdaq-style Star Market.
Chaozhou Three-Circle, a major domestic manufacturer of high-capacitance MLCCs, climbed around 8 per cent on the Shenzhen exchange, pushing its year-to-date advance above 130 per cent. Its Hong Kong-listed shares also rose 5 per cent on the same day.
Upstream suppliers ride the wave
The momentum extended to raw-material suppliers further up the value chain. Jiangsu Boqian New Materials gained nearly 6 per cent, while Shandong Sinocera Functional Materials rose almost 3.5 per cent on Wednesday. The broad-based advance signals that investors are pricing in sustained demand across the entire MLCC supply chain, not just at the finished-component level.
Why it matters: the 'rice of electronics'
MLCCs are often called the 'rice of the electronics industry' because of their diminutive size and sheer ubiquity — they are essential in everything from smartphones and electric vehicles to the AI servers underpinning the current technology supercycle. The rapid expansion of power-hungry AI data centres and computing clusters has created acute supply constraints for high-capacitance variants, pushing prices higher and fattening producer margins.
Monthly shipments from the world's three largest MLCC suppliers — Japan's Murata Manufacturing, South Korea's Samsung Electro-Mechanics (SEMCO), and Japan's Taiyo Yuden — reached a five-year high in June 2026, according to a report published on Tuesday, 29 July 2026 by market research firm TrendForce.
Competitive backdrop
The global MLCC market has historically been dominated by Japanese and South Korean giants, but Chinese producers have been steadily climbing the value chain toward higher-specification, high-capacitance products that command premium pricing. The current AI-driven demand surge is accelerating that shift, as domestic manufacturers benefit from both volume growth and improving average selling prices.
What's next
With AI infrastructure spending showing no sign of abating and global shipment volumes already at five-year highs, analysts will be watching whether Chinese producers can sustain margin expansion into the second half of 2026 and whether supply constraints ease as capacity investments come online. Any softening in hyperscaler capex or a demand pivot away from current server architectures remains the principal downside risk for the sector.
