The South China Morning Post reports that global inventories of multilayer ceramic capacitors, or MLCCs, have reached a record low amid rising demand from AI infrastructure. UBS Evidence Lab data cited by the newspaper shows distributor inventory volumes fell 8% by August 9 from four weeks earlier.
The South China Morning Post reports that multilayer ceramic capacitors, known in the electronics industry as MLCCs, are facing a sharp inventory squeeze linked to demand for artificial-intelligence infrastructure. The components act as electrical buffers in circuit boards. According to the SCMP, they are being used in increasingly large quantities in high-performance servers, making them an important part of the hardware supporting AI systems.
The newspaper cites a Wednesday report from UBS Evidence Lab showing that worldwide distributor inventory volume for MLCCs declined 8% by August 9 compared with four weeks earlier. The SCMP describes that level as a record low and says the decline extended an existing downward trend. The source does not provide the underlying UBS report directly, so these figures are attributed to the SCMP’s account of UBS’s analysis.
The reported change in unit prices points in the opposite direction from inventory volume. The SCMP says the total value of distributor inventory rose 10% over the same four-week period while average unit prices continued to climb. On a year-on-year basis through the end of July, the newspaper reports that the unit price index increased 13%, distributor volumes fell 22% and inventory value rose 6%.
The inventory decline was also visible among major manufacturers, according to the SCMP’s summary of the UBS report. By August 9, Japan’s Murata Manufacturing had seen inventory volume fall 8% from four weeks earlier, while South Korea’s Samsung Electro-Mechanics had seen a 20% decline. The article identifies those companies as examples of the broader trend but does not report their explanations or confirm whether they characterize the situation as a shortage.
Tại sao nó quan trọng
MLCCs are small components used as electrical buffers in circuit boards, and the SCMP reports that high-performance servers use them in increasingly large volumes. The reported squeeze suggests that AI infrastructure demand is affecting another layer of the hardware supply chain beyond processors, memory and optical components.
The significance of the report is that AI infrastructure demand appears to be reaching a less visible but essential component of server construction. Public attention has focused heavily on processors, memory chips and optical modules, but MLCCs are used to stabilize electrical flows within circuit boards. If demand from high-performance servers is absorbing more of the available supply, the constraint could affect equipment makers even when headline accelerator supply is not the immediate bottleneck.
The price and inventory figures described by the SCMP indicate that the market is experiencing more than a simple increase in shipments. Distributor volumes are falling while the value of remaining inventory is rising, a pattern consistent with higher prices and tighter availability. That does not establish how much of the movement is caused by AI servers, however, because the source does not provide a breakdown of MLCC demand by end market.
UBS analysts led by Shingo Hirata wrote that supply-demand tightness could begin in AI-related and distributor channels before spreading to the wider market, the SCMP reports. This is an analyst assessment rather than a confirmed forecast. Its practical implication is that a component initially associated with specialized AI infrastructure could become relevant to other electronics markets if manufacturers and distributors continue drawing down inventories.
For companies building AI infrastructure, a prolonged squeeze could create an additional procurement and cost issue beneath the better-known accelerator shortage. The source does not quantify the effect on server prices, delivery schedules, cloud capacity or consumer electronics. It also does not establish whether manufacturers can increase output quickly enough to offset demand, so the broader economic effect remains uncertain.

The main open questions are how long the supply pressure will last, whether it spreads beyond AI-related and distributor channels, and whether higher prices affect server costs or availability. The source does not independently verify the UBS data or provide company responses from the manufacturers cited.
The first issue to monitor is whether the inventory decline continues in later UBS updates or reverses. The SCMP provides comparisons through August 9 and the end of July, but it does not give a longer forward outlook, a projected point of stabilization or evidence that supply has already improved. Without those details, the duration of the reported squeeze cannot be determined.
A second question is whether the pressure remains concentrated in AI-related channels. UBS’s analysts, as quoted by the SCMP, said tightness could spread to the overall market, but the article does not show that such a spread has happened. Future evidence would include inventory and pricing data for non-AI electronics, along with clearer information about which customers and applications are competing for supply.
The manufacturers named in the report also warrant follow-up. Murata Manufacturing and Samsung Electro-Mechanics are reported to have experienced inventory-volume declines, but the source does not include statements from either company about production, orders, capacity or pricing. Their responses would help distinguish a temporary channel adjustment from a sustained manufacturing constraint.
Finally, the UBS figures need to be assessed against other market evidence. The source does not independently confirm the data, identify the full methodology behind the inventory measures or quantify AI servers’ share of MLCC demand. Further reporting should examine company filings, manufacturer guidance and additional distributor data before drawing conclusions about the scale or permanence of the AI-driven effect.
