South Korea has announced plans to establish a new memory chip cluster in its southwestern region. Coupled with Samsung Electronics' disclosure of a 2450 trillion won long-term domestic investment plan, the nation's semiconductor industry is witnessing its most expansive blueprint for growth in decades.
From June 29th to 30th, analysts from Bank of America Securities, led by Simon Woo, and a team at Goldman Sachs headed by Giuni Lee, released research reports on South Korea's substantial memory investment initiative.
The core assessments from both institutions are highly aligned. The massive investment commitments from the South Korean government and Samsung Electronics underscore strong governmental backing for the long-term expansion of memory supply. However, constrained by infrastructure construction timelines and fab ramp-up schedules, any substantive impact on global memory supply is not expected to materialize for at least 8 to 10 years. Investors should temper expectations for any near-term supply-side shock.
The New Southwestern Cluster: An 800 Trillion Won Strategic Move
The South Korean government has declared its intention to create a new cluster of memory wafer fabrication plants in the country's southwest, with chip manufacturers' total capital expenditure projected at approximately 800 trillion won.
The government will provide support for infrastructure such as land, power, and water. However, Bank of America Securities anticipates that the infrastructure development phase alone will require at least five years.
Following that, constructing the new fab shells, initial capacity ramp-up, and pilot production will demand an additional 3 to 4 years. Overall, achieving meaningful volume output from the new cluster is projected to take a minimum of 8 to 10 years.
It's noteworthy that South Korea's existing memory fabs are primarily concentrated around the Seoul metropolitan area, including locations like Pyeongtaek, Yongin, Hwaseong, and Icheon. The newly planned southwestern cluster is situated farther from Seoul, necessitating significantly larger infrastructure investments and presenting greater construction challenges.
Bank of America Securities draws a parallel to TSMC's dispersed strategy in Tainan, Taiwan, noting that such capacity expansion away from core regions requires a much longer lead preparation period.
Doubling Capacity Target: Actual Growth Rate is More Moderate
South Korean memory chip makers have reiterated a plan to nearly double DRAM wafer capacity by 2030. While this appears to be a substantial expansion on the surface, it corresponds to only about a 15% compound annual growth rate (CAGR).
However, Bank of America Securities further points out that when factoring in the closure of older fabs and the longer manufacturing cycles for next-generation memory chips, the annual expansion rate of operational wafer capacity will be below 10%. The net wafer growth rate through 2030 is expected to be in the low single-digit percentage range on a compound basis.
Even if the construction of new fab shells in Yongin and Pyeongtaek accelerates, analysts believe it is unlikely to drive a significant near-term increase in memory output.
For memory stock investors, this implies that any near-term shifts in supply-demand balance will depend more heavily on variables from the demand side.
Samsung's 2040 Plan: The Capital Logic Behind 2450 Trillion Won
Goldman Sachs analyzed the major announcement made by Samsung Electronics on June 29, 2026.
Samsung announced it will invest a total of 2450 trillion won domestically over the next 15 years (2026–2040), with approximately 2100 trillion won allocated to the semiconductor sector, accounting for 76% of the total investment. The breakdown is as follows:
1650 trillion won is earmarked for existing fabs and projects under construction, including accelerating the completion of the Yongin Line 6 fab from 2047 to 2040.
400 trillion won is designated for two new fabs in Gwangju, a key component of the southwestern semiconductor cluster project.
56 trillion won will fund a new HBM fab near existing packaging facilities in the Chungcheong province.
For non-memory businesses, Samsung Display will receive 67 trillion won to establish a new production base in Chungcheong province, focusing on next-generation smartphone panels and high-resolution micro-display products.
In Gumi, Samsung will also set up a smartphone factory and a humanoid robot production line.
Goldman Sachs views the implied pace of capital expenditure growth in this announcement as reasonable. Their reasoning is as follows:
Assuming Samsung's domestic capital expenditure and R&D combined represent about 80% of the consolidated total (consistent with the company's 2022 announcement), and assuming an approximate 6% annual growth from 2029 to 2040, the cumulative domestic spending from 2026 to 2040 would be around 2500 trillion won, slightly above the officially stated 2450 trillion won figure.
This implies that, based on Goldman Sachs' forecasts for Samsung's consolidated capital expenditure plus R&D for 2026-2028 (125 trillion, 140 trillion, and 151 trillion won, respectively), the announcement suggests an implied annual growth rate of about 5% to 6% for 2029-2040, which Goldman Sachs does not consider aggressive.
On the other hand, Goldman Sachs also notes that this announcement covers only domestic investments. If future overseas capital expenditures are added, there could be potential for upward revisions to existing forecasts.
Over the past five years, Samsung has concentrated about 90% of its capital expenditure on semiconductors. The implied concentration of 76% for semiconductor capital expenditure in this announcement suggests a more diversified resource allocation compared to recent years.
Clear Long-Term Signal, Near-Term Pace Requires Calm Assessment
Synthesizing the analyses from both institutions, the key takeaways for investors can be summarized as follows:
First, the supply impact is a medium-to-long-term event. The 8 to 10-year construction and production cycle dictates that this investment will not alter the supply-demand dynamics of the memory market in the near term. There is no immediate need for concern about large-scale new supply putting pressure on memory prices.
Second, the policy signal carries more weight than short-term financial implications. The acceleration of new fab construction in Yongin and Pyeongtaek, along with the formal confirmation of the southwestern cluster, conveys the Korean government's clear intent to strongly support the long-term expansion of its domestic memory industry. This helps solidify market confidence in the long-term competitiveness of Korean memory firms.
Third, Samsung's valuation remains attractive. Goldman Sachs maintains a Buy rating on Samsung Electronics, with a 12-month target price of 480,000 won for common shares and 360,000 won for preferred shares. This represents a potential upside of approximately 48.6% from the current common share price (323,000 won).
Goldman Sachs' investment thesis is built on sustained strength in memory pricing, substantive progress in the HBM business, and more aggressive shareholder return expectations.
Fourth, details remain uncertain. Samsung did not disclose whether the 2450 trillion won investment includes R&D spending, nor did it reveal specific capacity plans for the new Gwangju fabs. The probability of adjustments to this 15-year plan in response to changing market conditions is high, and investors should dynamically track subsequent capital expenditure guidance.
Overall, the strategic significance of South Korea's memory investment plan far outweighs its potential as a short-term catalyst for financial performance. This is a long-distance race aimed at the 2030s.
