The September WASDE cut the 2026/27 US corn yield to 178.5 bushels per acre and ending stocks to 1.567 billion bushels, while lifting soybean production to a record 4.535 billion bushels and raising farm-price forecasts across all three major crops.
Three-month LME copper set a record at $14,875 a tonne on 10 September before falling about 3% on reports the White House was hesitating over refined-copper tariffs. Mine supply stays tight, with ICSG putting first-half global copper mine output down 1.1% year on year.
The US Energy Information Administration lifted its 2026 Brent forecast to $91.01 a barrel in the September Short-Term Energy Outlook, citing Middle East crude outages that averaged 6.7 million bpd in August and are seen persisting near 5.7 million bpd through the fourth quarter.
Huawei has raised the indicative price of its Ascend 950DT accelerator card above RMB 250,000, 20-50% more than quotes two months earlier, and Cambricon repriced its next-generation 690 by 20-30%, as scarce high-bandwidth memory and grey-market sourcing costs feed into AI hardware bills of materials.
Third-quarter contract talks settled with conventional DRAM up 13-18% and NAND up 10-15% quarter on quarter on server and AI demand, while spot prices stalled on weak consumer buying and SK Hynix and SanDisk introduced High Bandwidth Flash as a tier between HBM and SSDs.
TSMC says surging AI demand is stretching the chip industry beyond its normal planning cycle and is doubling down on equipment purchases, while ASML lined up Intel, TSMC and Samsung behind a move to 12-inch photomasks for High-NA EUV and advanced packaging stayed the tightest link in the chain.
USDA's September WASDE cut the 2026/27 US corn yield to 178.5 bushels per acre and ending stocks to 1.567 billion bushels while raising season-average farm prices for corn, soybeans and wheat, even as record soybean output and coal-driven urea costs reshaped the input outlook.
Copper retreated from an all-time LME high after reports that the White House has yet to decide on refined copper tariffs, flipping the cash-to-three-month spread into contango, while LME aluminium inventories fell to their lowest since 1990 and zinc touched a four-year peak.
Brent crude pushed above $100 a barrel for the first time since late July as attacks on Gulf shipping and Saudi energy infrastructure cut exports, while IEA data showed global oil inventories falling by another 95 million barrels in August and Atlantic Basin refining margins at record levels.
TSMC says its equipment demand has risen from 1x at the end of last year to 1.9x by July, the fastest pace in three decades, and it now has close to 20 fabs under construction. Substrate capacity and advanced packaging have emerged as the binding constraints on AI hardware shipments.
August DDR5 and DDR4 module contract prices rose by double digits on server and AI demand, while spot trading has stalled and NAND wafer prices eased slightly. The split leaves suppliers leaning on contracted server volumes rather than a broad consumer recovery.
TSMC's 3nm node is expected to become the company's largest revenue contributor for the first time in the second half of 2026, with quarterly output value seen above NT$400 billion. AI peripheral demand has also spilled into mature nodes, lifting second-quarter foundry revenue to a record.
Oil extended its rally on Monday after a drone strike shut Saudi Arabia's East-West pipeline, the main route for bypassing the Strait of Hormuz, while fresh attacks on shipping in the Gulf and the Red Sea compounded supply fears. European gas and coal firmed in sympathy as storage levels stayed well below seasonal norms.
