The third quarter of 2026 extended a trend we first saw in the spring. Supply pressure that started in a handful of product families has now spread from finished chips down to the materials every board and package is built on. AI infrastructure spending is the common thread, and we see its effects in nearly every category we source.
Here is what changed in Q3, what it means for the markets we serve, and how procurement teams can plan for the rest of the year.
Demand: AI Sets the Production Schedule
Memory remains the clearest example. According to Z2 Data’s August 2026 Electronic Supply Chain Insights report, Samsung, SK Hynix, and Micron have committed their DRAM and HBM output through 2027, and buyers are receiving only 60% to 70% of the volumes they request. HBM drives the shortfall.
Producing a single HBM wafer takes the place of three to four DDR5 wafers, so every gain in AI memory output comes directly out of mainstream supply. Z2 reports that distributors are advising customers to budget for price increases of 10% to 20% per month through year-end, and average DDR5 lead times have climbed from 17 weeks in March to 50 weeks.
The squeeze is not landing evenly across the memory market. Rising component costs are pushing end-product prices higher, and consumers are pulling back. Notebook makers are bracing for a weaker holiday quarter, with the major ODMs planning for Q4 orders 10% to 15% below last year, according to TrendForce.
Phone brands are also trimming their lower-priced lineups. In late October, Chinese phone makers discounted devices ahead of Singles’ Day to clear inventory, and NAND spot sellers responded with deeper cuts. TrendForce reports that 512Gb TLC wafer spot prices fell 9.19% in one week, to an average of about $16.88. DRAM spot trading stayed thin, and mainstream DDR4 prices edged up just 0.55%.
Foundries are applying the same priorities to mature process nodes. Power management ICs, analog parts, and automotive microcontrollers earn higher margins, so fabs schedule them first. Commodity logic, including the gates and buffers that share those production lines, waits its turn. Z2 data shows logic IC prices up 20.4% over six months, with lead times stretching to 15 weeks after a long period of stability.
Supply: Pressure Moves Into Board Materials
he biggest change this quarter sits below the component level. Mainstream grades of copper-clad laminate, the base material for printed circuit boards, rose roughly 270% in a year, according to Z2, and advanced grades that once shipped in weeks now take six months. Several causes stack on one another: Glass fiber is scarce, AI hardware is absorbing ABF and BT substrate capacity, and copper itself reached a record price after a reported export ban in Congo and a 25-year output low at Chile’s largest copper miner. Z2 estimates standard board BOM costs have risen 15% to 25% since Q1 2026, which means automotive, industrial, and consumer products are absorbing part of the cost of the AI buildout.
Passive components are working through their third round of price increases this year. Z2 reports that Yageo and Kemet raised capacitor prices roughly 50% to 65% across their lines in June and July, Samsung Electro-Mechanics added 30% effective Aug. 1, and Taiyo Yuden was expected to follow on Sept. 1. Higher silver, palladium, and nickel costs feed directly into MLCC and resistor pricing. With less than 30 days of MLCC inventory in the channel and no significant new capacity due for 18 to 24 months, pricing has little room to ease.
AI demand is now pressing on MLCCs from a second direction. The move toward AI inference and agent workloads is driving server CPU demand. Each CPU arrives on the board with its own power circuitry and DDR5 modules, and both rely heavily on high-capacitance MLCCs. TrendForce expects high-end MLCC shortages to peak in Q1 and Q2 2027, as Nvidia ramps shipments of its Vera Rubin platform starting in Q4 2026 and AMD sources specialized parts for its MI450 platform. Optical module makers are feeling the squeeze too, as communications-grade MLCCs join the list of constrained parts.
Input expenses keep climbing as higher silver, palladium, and nickel costs directly feed into MLCC and resistor pricing. Japan’s import prices rose 24.5% in September compared with a year earlier, TrendForce notes, and the metals used in MLCC electrodes (nickel, copper, and silver) carry much of that exposure. With less than 30 days of MLCC inventory in the channel, and with TrendForce not expecting new capacity from Murata before 2028 even though the company has pulled its expansion plans forward, pricing has little room to ease.
What to Watch by Market
Commercial and Industrial
Passives present the most immediate exposure for equipment manufacturers. Thin channel inventory, combined with price increases still rolling through supplier catalogs, makes forecast-based buying risky. Consumer-grade parts are the exception. TrendForce data shows low- and mid-capacitance MLCC spot prices fell roughly 5% in early October and have stabilized for now.
High-capacitance parts remain short and are expected to stay that way through the first half of 2027. With Q1 2027 pricing talks opening in November, TrendForce expects Japanese suppliers to match the price increases Samsung Electro-Mechanics has already made.
Automotive and Transportation
Z2 reports automotive-grade 32-bit MPUs on allocation with lead times as long as 52 weeks, compared with 38 weeks for non-automotive grades. Power components are tightening at the same time. A reported Samsung 8-inch fab closure has pushed general-purpose server PMIC lead times from 21 to 26 weeks up to 35 to 40 weeks, and discrete semiconductor stock fell 34.1% in a single month. Tier 1 suppliers should review BOMs line by line for MPU, PMIC, and MOSFET exposure.
Medical Manufacturing
Long product lifecycles make medical programs especially sensitive to obsolescence. Z2’s July 2026 report found that 42% of NXP’s catalog is marked end-of-life or last-time-buy, with 100 parts retired in 2026, the largest retirement wave on record. As demand concentrates on a smaller active catalog, medical OEMs should audit their NXP content now, place last-time buys where needed, and qualify secondary sources before allocation tightens further.
Aerospace and Defense
Two compliance dates fall before the end of the year. According to Z2, China’s truce on U.S.-specific export licensing for gallium, germanium, antimony, and superhard materials expires Nov. 27. The truce never covered China’s April 2025 rare-earth controls, and its ban on U.S. military end use remains in force regardless of how the truce resolves. In Europe, a wind-down exemption adopted June 15 allows existing contracts and payments for MCC-branded parts to continue, with national approval, through Dec. 31. Defense programs that rely on these materials or brands should confirm their compliance position before either date.
The Bottom Line for Procurement Teams
Memory, passives, mature-node logic, power semiconductors, and board materials are all constrained at once, and the two biggest drivers, AI capacity allocation and export controls, show no sign of easing before 2027.
TrendForce expects the high-end MLCC shortage to last through the first half of 2027. TSMC’s plan to raise mature-node pricing by up to 10% starting in January 2027, as reported by Z2, signals that cost pressure will carry into next year.
The teams that manage this period best will secure critical components before allocation windows close, maintain multiple qualified sources for at-risk components, and build obsolescence and last-time-buy reviews into their regular sourcing calendar.
