Today's supply chain and manufacturing highlights for June 13, 2026 — summaries, links, and commentary.
I. Chips & Critical Materials
1. Google in talks with Samsung for 2nm TPU memory I/O die as TSMC capacity limits push multi-foundry strategy
Summary:
According to Seoul Economic Daily on June 13, Google is in discussions with Samsung Electronics to produce the memory I/O die for its 10th-generation TPU (codename Icefish) on Samsung's 2nm process, while the core compute chip may remain on TSMC's 1.4nm node — a dual-track "TSMC compute + Samsung I/O" configuration. With TSMC holding roughly 73% of the global foundry market, surging AI chip demand has intensified capacity bottlenecks, pushing large tech firms toward multi-foundry sourcing. Samsung has already secured Tesla's roughly KRW 25 trillion autonomous-driving chip order and Nvidia's LPU business, and supplies more than 60% of HBM for Google TPUs. Korea Investment & Securities forecasts that if the order materializes, Samsung's non-memory business could turn profitable in Q4 2026, reaching quarterly operating profit of KRW 731 billion in Q4 2027.

Commentary:
AI accelerator supply chains are shifting from TSMC single-source dependence toward split sourcing of compute and I/O — advanced-node capacity tightness is now driving structural multi-sourcing among hyperscalers.
2. China's tungsten export curbs threaten Japan's AI chip chain; WF₆ prices up over 200% YoY
Summary:
South China Morning Post reported on June 13 that after China tightened tungsten exports, Japan's Showa Denko Kanto and Central Glass may halt tungsten hexafluoride (WF₆) production in July as inventories run out, having already warned Samsung, DB HiTek, and other customers of potential disruptions. Market data show WF₆ prices up more than 200% year on year; ibuychem data on June 10 put five-nines (99.999%) WF₆ above CNY 1,700/kg (~USD 251), roughly triple a year earlier. WF₆ is used for CVD tungsten films in advanced logic and memory at 3–7nm nodes; tungsten powder accounts for more than 60% of production cost. Per Nikkei Asia, Japan's tungsten imports from China fell 50% in April versus the 2025 monthly average, with alternative sources still hard to secure.

Commentary:
Tungsten controls have escalated from raw-material cutoff to specialty-gas capacity exit — after Japanese producers stop in July, storage and advanced-node BOM step-ups will hit fab procurement before helium shortages fully bite.
3. China's InP export licensing delays of ~60 business days strain AI data-center optical interconnects
Summary:
Reuters reported on June 11 that China's export licensing regime for indium phosphide (InP) substrates, in place since February 2025, is delaying shipments critical to high-speed optical chips in AI data centers; Coherent CEO Jim Anderson traveled to China with President Trump's delegation partly to press for faster InP export approvals. AXT, the world's second-largest InP substrate producer, called "InP export permits the most significant challenge we currently face"; its Chinese subsidiary received its first export permits only in June 2025, leaving a large order backlog. Market data show 6-inch InP wafer prices up roughly 250% to about USD 5,000 since restrictions began; Lumentum's order backlog extends into 2028. Domestic Chinese producers such as Yunnan Germanium and Guangdong Xiandao are expanding, but overseas customers cannot switch suppliers quickly due to lengthy qualification cycles.

Commentary:
AI infrastructure bottlenecks are spreading from GPUs to a ~USD 200 million InP substrate market — optical module lead times and data-center expansion schedules are now implicitly gated by material licensing regimes.
II. Geopolitics & Logistics
4. US warns India against violating Hormuz blockade as Indian seafarer deaths trigger diplomatic protest
Summary:
Rediff.com reported on June 13 that the US State Department said it conveyed to India that violations of the US naval blockade in the Strait of Hormuz and illicit transport of Iranian oil will not be tolerated. Indian External Affairs Minister S. Jaishankar called US Secretary of State Marco Rubio on June 13 to protest Indian nationals killed in US military strikes on merchant vessels off Oman; India also summoned the US chargé d'affaires on June 12. Hormuz shipping has been severely disrupted since February 28 US-Israel strikes on Iran; the US has maintained a blockade since April 13 to restrict Iranian oil trade. Despite a fragile ceasefire from April 8, maritime traffic has not normalized. Geopolitical tension plus rerouting and war-risk premiums continue to push up Asia–Europe and transpacific logistics costs.

- Asia Global Institute, HKU — The Strait of Hormuz crisis: Impact on supply chain and the financial market
Commentary:
Hormuz has evolved from an energy chokepoint into a compound crisis of multilateral enforcement and shipping security — if India-US friction escalates, compliance costs on South Asia–Middle East–East Asia routes will rise further.
5. Container rates rise for a sixth straight week; carriers target USD 6,000–7,500/40ft Asia–Europe FAK from June 15
Summary:
Seatrade Maritime on June 12 and The Loadstar reported the Shanghai Containerized Freight Index (SCFI) climbed another 9.5% to 2,985.22 points, while Drewry's World Container Index (WCI) reached USD 3,549/FEU on June 11 (+3% week on week). Spot rates stood at roughly USD 3,768/40ft Shanghai–Rotterdam (+5%), USD 4,683/40ft Shanghai–Los Angeles (+3%), and USD 5,870/40ft Shanghai–New York (+7%). Maersk will lift Asia–Europe FAK rates to USD 6,000–6,500/40ft from June 15, with July 1 FAKs pointing to USD 7,500/40ft for North Europe and the Mediterranean; CMA CGM announced a USD 4,000/40ft peak season surcharge (PSS) on Asia–US lanes from July 10. Analysts cited front-loaded bookings for Prime Day and World Cup-related demand, Red Sea diversions lengthening voyages, and Hormuz-driven bunker costs keeping June–July space extremely tight.
Links:
- Seatrade Maritime — Container freight rates continue march northwards (June 12, 2026)
- The Loadstar — Carriers keep the price pressure on – a 'shock and awe' PSS the standout
Commentary:
The freight upswing has shifted from Middle East fuel pass-through to early peak season plus carrier pricing power — if July tariffs and PSS stack, landed-cost models should stress-test USD 6,000–7,500/FEU scenarios.
6. Asia is "not running out of oil — it's running out of everything oil makes": naphtha crisis hits plastics, medical, and fertilizer chains
Summary:
EBC Financial Group and Yahoo Finance reported recently that the Hormuz crisis leaves Asia importing roughly 70% of its naphtha from the Gulf; LG Chem has idled an 800,000 t/y ethylene cracker at Yeosu and regional petrochemical producers have declared force majeure. A mid-March survey by Korea's plastics industry federation found more than 70% of firms received resin reduction or suspension notices and 92% were warned of price increases; polypropylene and PVC used in medical packaging and disposables are tightening in tandem. Asian naphtha premiums versus Brent briefly approached USD 173/ton; if disruption extends into H2 2026, analysts expect naphtha 30%–50% above pre-crisis levels and plastics/chemicals up another 15%–25%. Academics and industry are discussing a "Middle East plus one" diversification strategy, echoing post-pandemic "China plus one" thinking.

Commentary:
Petrochemical stress is penetrating the "plastics everywhere" BOM layer — medical disposables, food flexible packaging, and electronics housings face simultaneous shortages and inflation, with Southeast Asian SME exporters most exposed.
7. Severe West Africa port congestion; Conakry, Guinea berthing waits reach two months
Summary:
Basenton's June 2026 update reported chain-reaction congestion across Red Sea, East Africa, and West Africa ports due to rerouting and vessel bunching. Berthing waits at some Conakry, Guinea ports have surged to roughly two months, and major carriers and forwarders have jointly stopped accepting cargo to certain West African ports; yard utilization at Lagos/Apapa, Abidjan, Tema, and Conakry hubs is at capacity, with destination congestion surcharges (CFD) and port additional handling fees (PAE/PAI) aggressively imposed since early June. At Kenya's Port of Mombasa, vessel delay rates hit 94.12%, with slow inland multimodal clearance leaving supply chains in Kenya and landlocked neighbors lagging by months. Dual Red Sea and West Africa congestion further tightens Asia–Europe–Africa lane capacity.

Commentary:
Rerouting gains are being consumed at African ports as berthing delays and surcharges — West African project and bulk importers must reserve cash flow and alternate routing for ~60-day detention risk.
III. Capacity & Manufacturing
8. Korea ready-mix concrete strike enters day six: 117 sites halted, 160,000 m³ of pours delayed
Summary:
Seoul Economic Daily reported on June 13 that the Seoul metropolitan ready-mix concrete delivery union walkout that began June 8 continues. The Construction Association of Korea said that as of 5 p.m. June 12, concrete supply halted at 117 sites operated by 25 major builders, delaying roughly 160,000 m³ of pours — equivalent to about 26,200 mixer-truck loads; more than 19,000 sites are active in the metro area, so actual impact may be larger. The association held an emergency industry meeting on June 13, calling for an immediate return to work and requesting government action to shorten mixer-truck supply review cycles from two years to one and ease batch-plant requirements on large national projects. Union and management continue negotiations under Ministry of Land mediation; the union proposes raising per-trip delivery rates by KRW 5,200 (KRW 1,000 above the June 9 tentative deal rejected by members). Samsung Pyeongtaek and SK hynix Yongin semiconductor cluster pours remain affected.

Commentary:
Korea's expansion bottleneck is spilling from gases and equipment into site concrete — if Yongin and Pyeongtaek face more than a week of continuous shutdown, 2027 capacity timelines risk irreversible slippage.
9. GM to mass-produce sodium-ion grid batteries in Michigan; vehicle roadmap shifts toward LMR chemistry
Summary:
Manufacturing Digital on June 13 and electrive on June 12 reported General Motors will develop and manufacture sodium-ion batteries at its Wallace Battery Cell Innovation Center in Warren, Michigan, in partnership with Peak Energy for US grid-scale storage; GM Ventures is investing and GM retains exclusive manufacturing rights. Peak says sodium-ion paired with its cooled storage system costs roughly 20% less than conventional LFP setups and eliminates energy-intensive active cooling. Meanwhile, GM battery chief Kurt Kelty indicated the vehicle roadmap may focus on lithium-manganese-rich (LMR) chemistry rather than LFP; LFP cells starting production at Spring Hill, Tennessee in June will pivot to stationary storage rather than EVs. GM is deploying 10,000 batteries into grid infrastructure and a 7.2 MWh second-life battery project in Michigan amid tariff and localization pressures.

Commentary:
North American battery supply chains are splitting by application — LMR for vehicles and sodium-ion/LFP for storage — a procurement restructuring shaped jointly by tariffs and IRA 45X production credits.
IV. Policy & Supply Chain Structure
10. Global manufacturer safety stock hits highest level since January 2023; shortages index at 3.5-year high
Summary:
The GEP Global Supply Chain Volatility Index, reported via Supply Chain Outlook, showed that in May 2026 manufacturers across North America, Europe, and Asia accelerated front-loading and expanded safety stock against inflation, shortages, and geopolitical uncertainty. May safety-stock levels reached their highest since January 2023; global demand for raw materials, commodities, and intermediate goods was the strongest since March 2022. Material shortages in May hit their highest severity in 3.5 years. The North American index rose to 1.69, its highest since August 2022; Asia eased modestly from 3.79 to 2.96 but remained the most strained region globally, with stronger purchasing reported in Japan, India, South Korea, and Taiwan. Analysts warn that if demand undershoots, front-loaded buying could trigger a H2 2026 destocking correction.

Commentary:
Global manufacturing is in collective stockpiling mode — short-term buffer against geopolitical shocks, but if H2 2026 demand disappoints, inventory correction will collide with elevated freight rates.
11. US House passes DOMINANCE Act, institutionalizing overseas critical-minerals diplomacy
Summary:
MINING.COM and White & Case reported in June 2026 that the US House passed the Developing Overseas Mineral Investments and New Allied Networks for Critical Energies (DOMINANCE) Act (H.R. 7037) on June 8 with strong bipartisan support. The bill would establish a Bureau of Energy Security and Diplomacy at the State Department, authorize multi-year energy-security compacts with partner countries, and lead US participation in the Minerals Security Partnership (MSP), prioritizing mining, processing, and refining projects aligned with US and allied national security interests. It targets China's roughly 70% share of global rare-earth mining and ~90% of processing. Separately, USA Rare Earth selected Cherokee County, South Carolina for a USD 1.2 billion NdFeB magnet and refined-metals plant targeting 6,400 t/y of magnets with 2028 commissioning; combined with Stillwater, Oklahoma, domestic NdFeB capacity is targeted at 10,000 t/y.
