Electronics Supply Chain Risk Report: Why BOM Costs Are Moving Again in Q2 2026

A Quarter That Changed the Math

When we published our first 2026 supply chain outlook in March, we wrote that the electronics supply chain had permanently changed. The past eleven weeks have shown how quickly that change can show up in actual purchase orders, quoted lead times, freight assumptions, and landed-cost models.

Since that report, the United States and Israel launched strikes against Iran, commercial traffic through the Strait of Hormuz has become severely constrained, memory contract prices have posted some of the sharpest quarterly increases the market has seen in years, selected discrete and power semiconductor families have moved into 40- to 60-plus-week lead times, and the U.S. tariff regime has shifted again as the Section 122 surcharge moves through the courts. The conflict began on February 28, 2026, and public reporting from CRS described pre-war Hormuz traffic at roughly 130 ships per day, falling to only a handful of daily transits by April.¹

This is the first installment of PPSI’s new Quarterly Supply Chain Report series. The pace of change in the electronics market has made a once-a-year update insufficient. Our customers need visibility into what is happening now and what is likely to affect the next ninety days of procurement activity, so they can make program decisions with the best information available.

The headline is straightforward: nearly every major cost input PPSI tracks is moving in the wrong direction at the same time. Components, memory, energy, freight, and tariffs are all under pressure simultaneously. There is no single disruption to manage around. There is a stack of overlapping disruptions, each one feeding the next.

Q2 Buyer Actions

For OEM buyers, the most important actions this quarter are practical and immediate:

• Re-quote any BOM priced before April before committing to customer pricing.
• Lock near-term requirements for memory, discretes, MOSFETs, diodes, IGBTs, and ESD devices wherever demand is known.
• Identify Nexperia exposure on approved vendor lists and qualify alternates wherever possible.
• Review HTS classifications, country of origin, and China-origin content before the July 24 Section 122 date.
• Preserve customs documentation in case Section 122 litigation creates refund opportunities.
• Treat supplier lead times as part-number-specific, not category-wide, and validate current guidance before customer commitments.

The Iran War and Semiconductor Materials

The Middle East conflict has moved from a regional security issue to a direct electronics supply chain issue. The war that began on February 28, 2026 has severely disrupted normal commercial assumptions around the Strait of Hormuz. Before the conflict, roughly 130 ships transited the strait each day. By April, public government reporting described only a handful of ships risking the passage daily, and later shipping reports have continued to show severely limited traffic.²

Even if a diplomatic agreement reopens the strait, supply chains should not assume an immediate return to normal. Normalization will have to account for war-risk insurance, vessel backlogs, mine risk, port congestion, rerouting decisions, and carrier confidence. In practical terms, Hormuz is not simply an on/off switch. It is a risk zone that could take months to normalize.

The energy effect is already visible. Brent crude traded near $120 per barrel in the early weeks of the conflict before settling lower, and the International Energy Agency announced a 400 million barrel emergency stock release. Higher energy prices matter to electronics because they flow into fab power costs, chemical production, freight, packaging materials, and global inflation. But for electronics buyers, the larger issue is what the conflict is doing to semiconductor manufacturing materials.³

Three materials matter most.

The first is helium. Qatar’s Ras Laffan-linked production disruption removed roughly one-third of global helium supply from the market, and QatarEnergy declared force majeure in early March. Helium is used in semiconductor manufacturing for cooling, purging, and process-control applications, and there is no simple drop-in substitute for several critical fab uses. Even after production resumes, supply normalization may take weeks or months as logistics, contract allocation, and inventory positions reset.⁴

The second is bromine. Israel and Jordan together account for roughly two-thirds of global bromine production. Bromine is a feedstock for semiconductor-grade hydrogen bromide and related specialty chemistries used in advanced chipmaking, especially etch processes. This has not yet become a full shortage, but it is a concentrated geographic risk sitting near an active conflict zone.⁵

The third is sulfur and sulfuric acid. Gulf producers supply sulfur and related inputs that support mining, leaching, and refining of critical materials used across semiconductor, battery, and electronics supply chains. Sulfur was already a pricing concern before the conflict escalated. Hormuz has turned that pricing concern into a broader lead-time and availability concern.

For East Asian semiconductor manufacturers, the exposure is significant. South Korea imports roughly 70 percent of its crude oil from the Middle East, and the region’s memory and logic manufacturers are now operating in an environment where energy, specialty gases, specialty chemicals, and freight are all less predictable than they were at the start of the year. Samsung and SK Hynix have meaningful high-bandwidth memory contract coverage, but a prolonged materials or energy disruption can still affect production planning, commodity DRAM availability, and pricing outside long-term agreements.⁶

For PCBA and component buyers in the United States, the practical effect is simple: the materials feeding the global semiconductor industry are now exposed to a war zone, and the buffer that existed when the conflict began is being consumed faster than it can be replenished.

Memory: One of the Sharpest Shortages in Fifteen Years

The memory market has moved from constrained to strategically allocated. TrendForce reported that conventional DRAM contract prices rose 90 to 95 percent quarter over quarter in Q1 2026. For Q2, TrendForce projected another 58 to 63 percent increase for conventional DRAM and a 70 to 75 percent increase for NAND Flash contract prices. The cumulative effect is that memory has been repriced upward with no near-term reversal visible.⁷

The underlying driver is artificial intelligence infrastructure demand. TrendForce has revised 2026 capital expenditure for the top nine global cloud service providers to approximately $830 billion, up 79 percent year over year. That spending is being concentrated in high-performance GPU clusters, AI accelerators, high-bandwidth memory, enterprise SSDs, networking, and high-power-density data centers.⁸

Samsung and SK Hynix, which together account for a large majority of global DRAM production, have reallocated capacity toward high-bandwidth memory and enterprise SSDs to serve AI workloads. That leaves general-purpose DRAM, DDR4, certain DDR5 categories, embedded memory, and consumer or industrial NAND with less available supply than buyers expected twelve months ago.

The implications for industrial, aerospace, defense, and energy electronics customers are direct. Embedded memory devices, automotive-grade flash, and DDR4 and DDR5 modules used in industrial controllers, instrumentation, test systems, and defense electronics are all being pulled into the same allocation environment as AI server memory. DDR4, which many buyers expected to soften as it approached end of life, has instead become one of the more volatile categories in the market.

For OEMs working with PPSI, the operational consequence is that memory should now be treated as a strategically managed component category, not as a commodity buy. Pricing volatility is high, lead times are extended, and allocation cuts can happen with limited notice. Buffer inventory, multi-source qualification, and early commitments to forecast volumes are no longer optional best practices. They are the difference between shipping on schedule and missing a delivery commitment.

Discrete Semiconductors: Public Averages Are Rising, and Constrained Families Are Worse

Lead-time and pricing data in this section combines public market reporting with PPSI distributor and manufacturer communications received through May 2026. Supplier guidance can change without notice and should be validated at the part-number level before customer commitments are made. Public checks show rising lead times across semiconductor segments, while PPSI supplier intelligence shows that specific approved parts can be substantially worse than category averages.⁹

Public distributor checks show semiconductor lead times lengthening across several categories. MOSFET lead times are rising, and some public averages remain below the most constrained families in PPSI’s supplier intelligence. That difference matters. A public average can show a 25- to 37-week MOSFET market while a specific approved part on an industrial or aerospace BOM is quoting 52 weeks or more.

The current picture from PPSI supplier intelligence is as follows:

On pricing, supplier and distributor communications reviewed by PPSI show increases concentrated tightly in the next sixty to ninety days. STMicroelectronics implemented price increases on April 1, 2026: 5 percent on microcontrollers and 15 percent on the remainder of the portfolio. Those increases were only recently entered into STM’s order system, so they will continue to work their way through customer quotes over the coming weeks.

onsemi has announced increases across a substantial portion of its portfolio. Because onsemi is a major automotive supplier, extended lead times may increase the risk that automotive demand receives priority over industrial demand when capacity is constrained. That does not mean every industrial order will be decommitted, but it does mean industrial-program buyers should not assume allocation neutrality.

Diodes Inc. implemented new price increases on at least 75 percent of its portfolio effective May 1. NXP is implementing 10 to 30 percent increases on June 1, with confirmed orders generally held at original pricing at manufacturer discretion and new lead-time orders priced at the new rates. Texas Instruments has announced new pricing on most of its portfolio effective July 1, 2026. Skyworks is implementing price hikes on June 4.

For procurement teams managing PPSI customer programs, the practical implication is that any open quote more than two to three weeks old may be understated. BOMs priced before April should be re-quoted against current pricing before being committed. Programs with deliveries scheduled beyond the third quarter that have not yet been ordered are exposed to a stack of cost increases that may not yet have hit the planning model.

Tariffs: The July 24 Cliff Is Now Also a Legal Question

The tariff environment has become more complicated since our March report. The Section 122 global surcharge imposed a 10 percent ad valorem duty on covered imports for a 150-day period beginning February 24, 2026. That makes July 24 the scheduled expiration date unless Congress extends the measure.¹⁰

The legal posture has changed, however. On May 7, the U.S. Court of International Trade held that the Section 122 surcharge exceeded presidential authority. The government appealed, and on May 12 the U.S. Court of Appeals for the Federal Circuit issued an administrative stay. As a result, importers should treat Section 122 as currently payable while the case proceeds, while also preserving documentation in case litigation creates refund or protest opportunities.¹¹

This is not the only tariff exposure affecting electronics. The Section 232 semiconductor action is no longer merely an investigation in review. A January 2026 proclamation imposed 25 percent duties on certain advanced computing chips and specified derivative products, effective January 15, while also directing continued monitoring and negotiations covering semiconductors, semiconductor manufacturing equipment, and derivative products.¹²

Section 301 exposure also remains important for China-origin semiconductors and electronic components. A December 2025 USTR action set a new China semiconductor tariff line at an initial 0 percent rate, scheduled to increase on June 23, 2027 to a rate that will be announced later. That action sits alongside other existing China-origin tariff programs and should be evaluated by HTS classification and country of origin, not by product category alone.¹³

For OEM customers, the July 24 date should be on the program calendar, but it should not be viewed as a guaranteed cost reset. The most realistic planning model is a range of outcomes: continued collection while litigation proceeds, potential refund scenarios for certain entries, targeted sectoral tariffs under Section 232 or Section 301, and a possible gap for categories not yet covered by longer-term authority.

Tariff exposure is HTS-, country-of-origin-, and program-specific. PPSI can help customers estimate landed-cost impacts and identify exposure at the BOM level, but customers should confirm binding classification and duty treatment with their customs broker or trade counsel.

Where feasible, PPSI continues to recommend U.S.-based assembly as one way to reduce exposure on the highest-value portion of the production process. The exact benefit depends on component origin, classification, valuation, and finished-good treatment, but local assembly can give OEMs more control than importing fully assembled product into a fast-changing tariff regime.

The Nexperia Crisis Has Not Ended

The Nexperia situation we covered in March has continued to evolve, and not in a positive direction. The Dutch government, Wingtech, Nexperia Europe, and Nexperia China remain locked in a dispute over control, governance, wafer supply, and operational separation.

Nexperia B.V. has said that its China entities are not under its governance, and that it cannot oversee delivery or quality from those entities. Wafer shipments between European operations and China have been disrupted since late 2025. Nexperia China has moved to secure domestic wafer supply for its 2026 IGBT production, including capacity from Wingtech’s foundry Wingsky Semi and other Chinese wafer suppliers, but qualification and quality assurance remain open issues.¹⁴

The dispute has also moved deeper into litigation. In late May, Wingtech filed suit in China seeking damages and the restoration of control over Nexperia. That development reinforces PPSI’s view that the disruption is unlikely to resolve cleanly in the near term.¹⁵

Current PPSI guidance to customers is that new Nexperia material may not be available until July 2026 or later for some higher-risk legacy devices. Programs that include Nexperia parts on the approved vendor list should assume the disruption persists through the second half of 2026 and qualify alternates wherever possible.

What This Means for OEM Programs

The combined effect of the disruptions covered in this report is that the cost and risk profile of many active hardware programs has shifted materially since the start of 2026. A BOM priced in January is likely more expensive to source today, and may be more expensive again by September. A program scheduled to deliver in Q4 against pricing from earlier in the year is exposed to multiple stacked cost increases that may not yet have flowed through to the planning model.

The procurement playbook in this environment looks different from the playbook of twelve months ago. The window for re-quoting and re-committing is narrower. The penalty for waiting is higher. The value of strategic buffer stock, multi-source qualification, and proactive supplier engagement has gone up sharply. And the importance of working with a manufacturing partner who has visibility into pricing and lead-time movement, and who will flag changes early enough to act, has gone up with it.

At PPSI, we are working with customers to translate these market shifts into specific program decisions. That includes flagging BOM items exposed to known June and July price increases, identifying alternate parts that can be qualified before the next allocation cycle, and structuring strategic buffer inventory for components where the risk of being decommitted is highest. It also includes communicating clearly when pricing has moved, so customers are not surprised at invoice time.

The Bottom Line

The electronics supply chain in Q2 2026 is being shaped by a war in the Middle East, an AI-driven memory allocation cycle, selected discrete semiconductor lead times stretching into 40- to 60-plus-week territory, a Nexperia dispute that has not resolved, and a tariff regime that may change again within sixty days.

The forces driving these disruptions are not purely commercial. They are geopolitical, structural, and largely outside the control of any individual customer or manufacturer. The OEMs that navigate this environment successfully will be the ones that treat supply chain management as a continuous program discipline rather than a periodic purchasing event.

The companies that get caught flat-footed will be the ones that quoted programs against last quarter’s pricing and assumed the world would stand still long enough to ship them.

Your designs deserve a supply chain partner that is paying attention every day. PPSI is here to help you build one.
