How long semiconductor price increases could last

As of 2026-10-12. Scope: RAM, HBM, SSD storage, advanced processors and mature-node chips. Dates beside links identify the source publication or earnings-call date. Forecasts remain forecasts; the conclusions labeled assessment are reasoned interpretations of the evidence.

TL;DR

Assessment: Expect memory to remain expensive through 2027, with meaningful risk extending into 2028. The evidence does not establish when prices peak or return to 2025 levels. Continued shortages, slower increases and occasional retail discounts can all coexist.

• RAM and conventional DRAM: Tight conditions through 2027 are well supported. Larger new-fab contributions become more plausible in 2028, but that is a supply milestone, not a promised price decline. (TrendForce, 2026-07-30)
• HBM for AI accelerators: The published outlook still points to strong pricing in 2027. It does not provide a reliable date for a reversal. (TrendForce, 2026-09-29)
• NAND and SSDs: The second half of 2027 is a credible earlier-relief scenario. However, current forecasters differ on how much conditions improve, so it should not be treated as a dependable end date. (TrendForce, 2026-10-08; Omdia, 2026-10-02)
• CPU and GPU manufacturing: Advanced capacity pressure is a multiyear issue, but evidence about foundries cannot establish a common retail CPU/GPU price path. (TSMC, 2026-07-16)
• Mature-node chips: Conditions vary by application. UMC's firm-price guidance does not support applying memory-style increases to every semiconductor. (UMC, 2026-07-29)

What the latest evidence actually says

TrendForce's September 30 forecast puts Q4 2026 conventional DRAM contract prices up 10–15% quarter over quarter and NAND Flash up 15–20%. It expects enterprise SSDs to be the only memory category with faster price growth than the preceding quarter. These are upstream contract-price forecasts, not completed-quarter results or predictions for every retail product. (TrendForce, 2026-09-30)

Micron's September earnings remarks forecast industry supply constraints for both DRAM and NAND in calendar 2027 and 2028, without identifying when DRAM supply and demand rebalance. Yet management also expects a more moderate rate of price increases in fiscal 2027. Its reported fiscal Q4 DRAM prices rose by a high-teens percentage sequentially; NAND prices rose approximately 30%. These are company results and management expectations, not independent industry consensus. (Micron, 2026-09-30)

Samsung independently described limited capacity and a server-focused product allocation in July. It expected memory undersupply in the second half of 2026 despite weaker mobile and PC demand. That corroborates the allocation problem, although this release does not itself establish a 2028 shortage forecast. (Samsung, 2026-07-30)

Assessment: Evidence is stronger for sustained high prices than for uninterrupted increases every quarter. Four outcomes must be separated:

1. Slower increases: Prices still rise, just less quickly.
2. A plateau: Prices stop rising but remain expensive.
3. A decline: Prices fall from their peak, potentially remaining well above older levels.
4. A return to 2025 prices: A much larger and more specific claim, unsupported by an established timetable.

For example, after a hypothetical doubling, a 20% decline still leaves the price 60% above its starting point. Calling that “normalization” would obscure the actual cost.

RAM and DRAM why the pressure can last

The main constraint is usable output for the products customers need. TrendForce expects DRAM demand growth to outpace supply growth in 2027. Its July analysis places meaningful new-fab ramps in the second half of 2027 and substantial resulting output in 2028. It also identifies HBM's greater wafer requirements as a drag on conventional DRAM bit expansion. (TrendForce, 2026-07-30)

SK hynix offers evidence of a real supply response: it reported HBM4 mass shipments beginning in Q2 2026, planned a second-half ramp, and was accelerating M15X production. It also planned capacity expansion after the Yongin Phase 1 cleanroom opens in early 2027. Nevertheless, it said customer demand exceeded its supply capabilities and described subsequent investment as phased according to demand and efficiency. (SK hynix, 2026-07-29)

Micron's planned milestones include initial Idaho ID1 wafer output in mid-2027 and Singapore NAND output in the second half of 2028. Japan's DRAM expansion targets initial output in late 2028. The company explicitly says new fabs become more meaningful several quarters after initial output. (Micron, 2026-09-30)

Assessment: A building, cleanroom, installed tool, qualified process and saleable shipment are different stages. Capital expenditure therefore cannot be translated directly into a date when RAM becomes cheap. Process improvements and better yields can help before a whole new fab ramps, while rising demand can absorb the additional output afterward.

DDR4 also has a distinct legacy-supply problem. TrendForce's May analysis found that Micron's Fab 6 expansion largely relocates existing production and serves long-lifecycle applications, without increasing Micron's total DDR4/LPDDR4 capacity. It forecast continued DDR4 undersupply through 2026. Assessment: Even if newer DRAM later becomes more affordable, shrinking legacy supply could prevent DDR4 from following the same path. (TrendForce, 2026-05-26)

NAND and SSDs the relief date is genuinely uncertain

There are three relevant current views:

• TrendForce, October 8: NAND supply constraints might ease in the second half of 2027 as new capacity arrives. Its same report expects DRAM to remain tight. (TrendForce, 2026-10-08)
• Omdia, October 2: Its public NAND Market Tracker abstract forecasts undersupply through 2027 despite moderating price growth. The detailed report is subscription-gated, so its undisclosed assumptions cannot be compared here. (Omdia, 2026-10-02)
• Micron, September 30: Its industry outlook extends NAND constraints through 2028, a materially more cautious planning horizon. (Micron, 2026-09-30)

Assessment: These views differ, but are not completely incompatible: a shortage can ease while the market remains undersupplied. Crucially, TrendForce's October statement is newer than Micron's September remarks. The difference cannot be dismissed as an old forecast overtaken by newer information. There is no demonstrated consensus on a 2027 or 2028 price reset.

The earlier-relief case has a clear mechanism. TrendForce expects higher-layer NAND transitions and new fabs to raise bit supply; weak consumer demand could then make the market less tight. Its July analysis also acknowledges the counterargument: faster AI adoption and SSD demand could absorb the extra supply. (TrendForce, 2026-07-30)

Client and enterprise SSDs already show different pressures. TrendForce reports that PC buyers have inventories and are reducing storage capacities to contain costs, restraining client-SSD increases. Enterprise demand remains much stronger, with much incremental supply committed. Assessment: A consumer SSD promotion could appear before enterprise supply improves; one discounted model would not prove an industry-wide reversal. (TrendForce, 2026-09-30)

HBM why its headline prices need careful reading

TrendForce's September 29 forecast projects a 121% rise in blended HBM average selling price in 2027. Its explanation includes both firmer pricing and a greater share of higher-priced HBM4, followed by HBM4e. It also expects limited advanced-process capacity and gradual yield ramps to keep supply tight through 2027. (TrendForce, 2026-09-29)

Assessment: A blended average changes when the product mix changes. This forecast must not be restated as “the identical HBM chip will cost 121% more,” nor applied to desktop RAM. For duration, its useful signal is sustained 2027 pressure. For magnitude, a buyer needs the particular generation, stack capacity, qualification and contract terms. The headline average cannot supply those answers.

CPUs GPUs and foundries have a different pricing chain

TSMC's January earnings call described 2026–27 as years focused on productivity improvement, with significant additional capacity expected in 2028–29. Management also distinguished changes in blended wafer selling prices from like-for-like pricing because technology mix changes. (TSMC, 2026-01-15)

In July, TSMC raised its 2026 capital-spending outlook to $60–64 billion and described strong AI demand potentially extending into 2029–30, while explicitly allowing for a dip. It also highlighted pressures on price-sensitive consumer markets. These statements concern demand and manufacturing economics; they are not published retail CPU or GPU price forecasts. (TSMC, 2026-07-16)

Assessment: Continued advanced-chip cost pressure into 2027 is plausible, and 2028–29 expansion could help. However, finished-product prices also depend on competition, product launches, inventory, memory and packaging costs, and the margins brands choose to retain. A foundry's higher revenue or average wafer price does not establish the increase on an unchanged gaming CPU or graphics card. No defensible universal end date emerges from these disclosures.

Mature-node analog and power chips

UMC reported Q2 2026 utilization of 85%, guided above 90% for Q3, and expected dollar average selling prices to remain firm. It identified recovering demand in power-management chips, sensors and microcontrollers. This supports improving demand without establishing a memory-like price surge. (UMC, 2026-07-29)

Infineon's August release identified AI data-center power solutions as its principal growth driver and noted recovering automotive orders and multiyear AI capacity reservations. Assessment: Even within power semiconductors, exposure to AI infrastructure changes the outlook. “All mature chips are getting cheaper” and “all chips stay scarce until 2028” are both too broad. (Infineon, 2026-08-05)

What could bring relief earlier or prolong the squeeze

Earlier-relief scenario: Consumers delay replacement, choose smaller memory/storage configurations, or brands draw down inventories. AI customers could also moderate procurement if costs or deployment economics deteriorate. TrendForce's October notebook outlook explicitly links higher component costs to weaker replacement demand. Such adjustments can reduce orders before new capacity is fully available. (TrendForce, 2026-10-08)

Longer-pressure scenario: AI and server purchases absorb extra supply; production ramps or customer qualification take longer; suppliers continue allocating scarce resources to higher-value products. Samsung's server prioritization and SK hynix's phased expansion make these credible mechanisms, although neither establishes an unlimited shortage. (Samsung, 2026-07-30; SK hynix, 2026-07-29)

Assessment: Neither scenario deserves an invented numerical probability. Near-term direction has stronger evidence than a multiyear turning point. The further out the forecast, the more demand, usable output and customer behavior can change together.

What this means for buyers in Japan

Actual shop observations illustrate the segmentation. AKIBA PC Hotline's September 12–19 survey recorded a tax-inclusive minimum of ¥55,980 for the DDR5-5600 16GB × 2 category. Its CPU survey found the Ryzen 7 9800X3D at ¥59,980, only ¥180 above its historical low. These are surveyed local offers, not national averages or guaranteed current prices. (AKIBA PC Hotline RAM survey, 2026-09-24; AKIBA PC Hotline CPU survey, 2026-09-24)

Assessment: Japanese retail prices also depend on exchange rates, distributor inventories and promotions. An upstream dollar-price forecast cannot determine an exact yen price or retail lag. For a necessary purchase, budgeting around currently available configurations is more defensible than assuming a broad near-term reset. For an optional upgrade, waiting may produce a better individual offer, but the evidence does not promise when.

Final assessment and confidence

• High confidence: Different chip categories require different answers; slower increases do not mean falling prices; fab announcements do not establish a retail relief date.
• Moderate confidence: Memory remains costly through 2027. Multiple suppliers and independent analysts support the underlying constraints, although the quarterly price path can change.
• Lower confidence: NAND relief begins in the second half of 2027, or substantial new DRAM output produces lower prices in 2028. Both are plausible; neither is a settled outcome.
• No credible precision: An exact peak month, a universal semiconductor normalization year, or a return to 2025 retail lows.

The practical answer is at least a 2027 planning horizon for expensive memory, with 2028 remaining a risk horizon rather than a promised finish line. NAND may improve sooner than DRAM. CPU, GPU and mature-chip prices should be judged at the product and application level.
