Weekly Supply Chain in Asia 2026-W36 (2026-08-27~2026-09-02)

Korean firms are expanding U.S. production bases as Washington restricts foreign power equipment and tightens clean energy tax credits, and a Korean defense delegation heads to Estonia to discuss cooperation beyond existing weapons systems. As South Korea’s national debt-to-GDP ratio improves on the back of chip-linked tax revenue, the economy faces a structural paradox: fiscal stability is currently leveraged on a cyclical upcycle, creating a “denominator effect” where the debt-to-GDP ratio improves because the GDP—the denominator—is inflated by semiconductor-linked growth, leaving little room for error should the semiconductor market enter a downturn.

This Week’s Events

Relocating Production Footprints

The U.S. government is pushing to reorganize its power grid supply chain around the U.S. and its allies. On August 26, 2026, the U.S. government signed an executive order restricting foreign power equipment in the bulk power grid, a move widely interpreted as a measure to exclude Chinese components from critical infrastructure. Analysts say Korean companies with local production facilities could become relatively more competitive in winning orders. LS Electric is planning a USD 240 million investment in North American production by 2030, while HD Hyundai Electric is investing USD 200 million to expand its transformer plant in Alabama. Hyosung Heavy Industries is also expanding its Memphis facility to increase capacity by over 50% by 2028.

This regulatory pressure extends into the battery and energy storage system (ESS) market, where the One Big Beautiful Bill Act tightened clean energy tax credit requirements to exclude prohibited foreign entities. The U.S. ESS market recorded 20.2 GWh of new installations in the second quarter of 2026, its largest quarter on record, taking the first half to 30.8 GWh and a 23% year-on-year increase. Korean battery manufacturers are substantially strengthening their local ESS and LFP production in the United States. LG Energy Solution is targeting 100 GWh of production capacity in North America by 2030, while Samsung SDI and SK On are ramping up local LFP production as Section 301 tariffs on Chinese non-EV lithium-ion batteries rise from 7.5% to 25%. Analysts expect firms with North American production bases to benefit as the entry barrier for Chinese LFP batteries rises.

Korean defense firms are also looking to extend cooperation beyond existing weapons systems, this time on NATO’s eastern front. A delegation of Korean defense companies, including Hanwha Aerospace, LIG Defense & Aerospace, and Hyundai WIA, is scheduled to attend the 1st South Korea-Estonia Defense Industry Business Forum on September 17, 2026. Estonia, which has allocated 5.4% of its 2026 GDP to defense with a procurement scale of EUR 1.27 billion (KRW 2.03 trillion), has already integrated Hanwha’s K9 howitzers and Chunmoo multiple launch rocket systems into its military. Weapons-system introductions could lead to follow-on business in ammunition, parts, and maintenance, repair, and overhaul (MRO), which could turn simple arms exports into a long-term defense partnership.

Jeju Semiconductor, a South Korean fabless semiconductor design firm, is partnering with FPT Semiconductor, a subsidiary of the Vietnamese IT group FPT, to construct a USD 100 million OSAT (Outsourced Semiconductor Assembly and Test) factory in Hanoi. Jeju Semiconductor has outsourced all wafer manufacturing and packaging to foundries and key partners, and the project would link a Vietnamese packaging and testing base to that design-centered structure through a consortium with Korean equipment and test firms.

What the Chip Cycle Costs at National Scale

The South Korean economy’s current fiscal health is heavily synchronized with the global semiconductor manufacturing cycle, creating a structural vulnerability. The Bank of Korea (BOK) recently raised its 2026 GDP growth forecast to 3.3%, citing stronger-than-expected performance in the first half of the year, a revision read as reflecting first-half growth that beat expectations on strong semiconductor exports. This growth has improved the national fiscal outlook, with the debt-to-GDP ratio projected to fall from 50.6% this year to 48.3% in 2027. However, analysts warn that this improvement is largely a “denominator effect” tied to semiconductor-driven growth in national tax revenue, which is projected to surge by 40.7% to KRW 584.4 trillion. If the semiconductor industry enters a recession, the resulting decline in corporate tax receipts and nominal GDP could rapidly deteriorate fiscal indicators, highlighting the economy’s reliance on temporary tax windfalls to fund rising mandatory expenditures.

Data Meets Physical Retail

In the digital and retail sectors, two deals tied data to physical retail. Itochu Corporation is acquiring approximately 38% of Dentsu Soken for up to JPY 215.2 billion to cross-sell IT services and leverage retail data for digital advertising. Itochu group companies Gate One and Data One will work with Dentsu on signage products, digital advertising and analytics using purchase data, and joint proposals. Dentsu Group keeps 62% and stays the parent, so this buys access to the analytics rather than control of them.

In Seoul, the retail market is shifting from duty-free, bulk-purchase models to high-experience flagship stores. Cushman & Wakefield Korea reported an 8.5% vacancy rate in Seoul’s major retail areas in the second quarter of 2026, with foreign credit card spending surging 50.8% year-on-year. Cushman & Wakefield Korea expects competition among global brands for flagship sites in prime locations to intensify.

In the fintech sector, Toss and Hana Bank launched the second season of their “Walking Savings” product, doubling the quota to 20,000 accounts. The product ties preferential interest rates to cumulative step counts recorded by the Toss pedometer.

Policy Rewriting Trade and Consumption

Regulatory and trade policies continue to shape the regional industrial landscape. The European Union is preparing for final negotiations on the Industrial Acceleration Act (IAA), which aims to prioritize EU-produced low-carbon products in public procurement. The proposal would expand the use of EU-made low-carbon products in public procurement, and France’s core goal in pushing stronger preferences is to protect manufacturing within the bloc from low-cost, subsidized imports from countries such as China. France wants steel held to the same origin test, which the Commission’s first draft had deliberately left out to avoid provoking Washington and New Delhi.

In China, the “East Data West Computing” strategy is moving data centers to the western provinces, where wind and solar are abundant and power is cheap.

In Bangladesh, a new import policy running 2026–2029 simplifies procedures and supports export-oriented industries, including provisions on imports under FTAs, CEPAs, and EPAs that could help reduce import costs through the use of trade agreements.

Finally, Japan will cut the consumption tax on food to 1% from April 2027 for two years, excluding dining out and alcohol — the first time the rate has fallen since the tax was introduced in 1989. Because restaurants and alcohol sit outside the cut, the same meal gets cheaper bought raw and stays flat bought cooked. Nothing in the Consumption Tax Act obliges anyone to pass the reduction on, so producers, wholesalers and retailers may keep the gap as margin instead — leaving restaurants competing against a discount their suppliers can decline to grant them.

Looking Ahead

The coming weeks will test the resilience of these localized strategies as firms navigate the intersection of fiscal policy and trade enforcement. The progress of the EU’s Industrial Acceleration Act negotiations in September 2026 will be a critical bellwether for whether the bloc leans toward French protectionism or German pragmatism regarding trade partner retaliation. Investors should also monitor the outcomes of the South Korea-Estonia Defense Industry Business Forum, which is expected to give Korean companies seeking to expand into Nordic and Eastern European defense markets an opportunity to build networks with local companies. Finally, track the market share shifts in the U.S. ESS sector as Korean battery manufacturers ramp up local production, which will serve as a key indicator of the pace at which Chinese competitors are being displaced from the U.S. clean energy supply chain.
