19/08/2026

Renewed US–Iran tensions pushed oil prices and global long-term borrowing costs higher. At the same time, concerns over AI valuations, massive capital expenditure and financing models weighed on sentiment. US equities fell for a third consecutive session, led lower by semiconductors and memory stocks, while defensive and energy sectors were relatively resilient.

S&P 500 fell 0.69% to 7,691.76

Dow Jones fell 0.22% to 53,343.40

Nasdaq fell 1.33% to 26,289.71

US 2-year Treasury yield was broadly unchanged at around 4.18%–4.19%.

US 10-year Treasury yield fell around 2 bps to 4.71%, after reaching an intraday high of around 4.75%, close to its highest level since early 2025.

News 1 — China’s Tech AI Transformation Accelerates: Xiaomi Smartphone ASP Hits Record High, Baidu GPU Cloud Surges 283%

* Xiaomi reported Q2 2026 revenue of RMB108.9bn and adjusted net profit of RMB6.2bn, showing resilience despite elevated memory costs and softer smartphone demand.

* Xiaomi reduced shipments of lower-end smartphones, upgraded its product mix and selectively raised prices, pushing smartphone average selling prices to a record high while keeping handset margins relatively stable.

* Management expects memory price increases to moderate in 2H, although absolute prices remain elevated. Xiaomi will continue using premiumisation to offset DRAM/NAND cost pressure.

* Xiaomi’s robot is scheduled to make its public debut at the 2026 World Robot Conference, while a new-generation Xuanjie chip is also expected, extending its ecosystem from smartphones → chips → EVs → robotics.

* Baidu reported Q2 revenue of RMB31.3bn, slightly below expectations of RMB31.6bn. AI now accounts for more than 50% of its core business revenue for a second consecutive quarter.

* Baidu AI Cloud infrastructure revenue reached RMB7.3bn, up 50% YoY, while GPU cloud revenue surged 283% YoY, marking a fourth consecutive quarter of triple-digit growth.

* However, adjusted profit per ADS was only RMB7.22 versus expectations of RMB9.75, highlighting that heavy AI infrastructure spending is still weighing on near-term profitability.

Market impact: Rising AI capex and memory demand in China, together with the possibility of Chinese rate cuts, remain supportive for GPUs, data centres, DRAM/HBM and semiconductor equipment over the longer term. However, Baidu’s earnings miss reminds investors that AI monetisation still needs time to catch up with spending.

News 2 — US–Iran Tensions Escalate Again: Trump Rejects Talks, UAE Detects Iranian Missiles and Suspends Trade

* Trump said on August 18 that the US would not hold talks with Iran now or in the future, further reducing hopes of renewed diplomatic negotiations.

* He also posted a map labelling the Strait of Hormuz as “new US territory”, which Iran immediately rejected.

* The US said the Strait of Hormuz remains open and operating normally, while Iran’s parliament speaker said it would remain effectively closed until demands including sanctions relief and asset unfreezing are met.

* A foreign oil tanker was attacked near the Strait of Hormuz on August 18, causing engine-room damage and crew casualties, increasing concerns over shipping and energy security.

* The UAE said its defence systems detected two ballistic missiles launched from Iran, with one landing outside UAE territorial waters and another falling within them.

* The UAE raised its alert level and suspended trade, commercial and financial transactions with Iran until further notice.

* Qatar and other mediators are still trying to facilitate a passage agreement between Iran and Oman as a potential route toward reopening broader negotiations.

Market impact: Continued Hormuz risks support oil prices and inflation expectations while keeping long-term Treasury yields elevated. This is particularly negative for high-valuation technology and AI stocks, while supporting energy and defensive sectors.

Positive note: If Qatar and Oman can broker a passage agreement, oil prices and bond yields could decline quickly, easing valuation pressure on technology stocks.

News 3 — AI’s Biggest Risk Is Shifting From “Demand” to “Financing”

* Bank of America’s August Global Fund Manager Survey showed investor sentiment at one of its strongest levels since 2022, with global equity allocations at their highest since November 2021.

* Cash allocations fell to just 3.5%, historically low and a sign that positioning is becoming crowded.

* An AI bubble remains the largest tail risk at 32%, while a disorderly rise in bond yields has risen to second place at 27%.

* Alphabet, Meta, Microsoft, Amazon, Oracle, Nvidia, Broadcom, SpaceX and AMD reportedly have around US$3 trillion in off-balance-sheet commitments.

* Around US$1.2tn consists of lease commitments that have not yet commenced, while another US$1.9tn relates to purchase commitments.

* The US$3tn total is around five times the roughly US$600bn these companies spent on capex over the past year and has increased sharply from around US$1.8tn just two months ago.

* This helps explain why investors are increasingly focused on AI data-centre financing, corporate bond issuance and long-term rates, as major technology firms and the US government compete for capital.

Market impact: If 10-year and 30-year Treasury yields keep rising, high-valuation and capex-heavy AI infrastructure, semiconductor and data-centre names could face further valuation compression.

Positive note: Off-balance-sheet commitments are not the same as immediately payable debt. If cloud revenue, AI subscriptions and compute demand continue growing rapidly, future cash flows may gradually absorb these investments. The key question is whether AI revenue can keep pace with AI capex.

News 4 — AI Model Competition Heats Up: GPT-6/Astra Rumours and GPT-5.6 Sol Discounts

* Market rumours suggest OpenAI’s next-generation Astra / GPT-6 model could potentially appear as early as Thursday, although this remains unconfirmed.

* Developers reportedly found the internal checkpoint codename “mewfour” in OpenAI-related repository commits.

* Some observers believe Astra could be the next flagship model, but its timing, naming and feature set remain unconfirmed.

* GPT-5.6 Sol is being offered at a 50% discount on OpenRouter and Vercel AI Gateway until September 18.

* Official OpenAI API and Azure pricing have not been reduced, so this is not an across-the-board GPT-5.6 Sol price cut.

* SemiAnalysis believes the promotion could significantly increase Sol usage statistics on OpenRouter and Vercel, platforms commonly used to track model market share.

* However, SemiAnalysis’ interpretation of the strategic intention remains a third-party view and has not been confirmed by OpenAI.

Market impact: AI competition is increasingly shifting from pure model capability toward performance + inference cost + developer ecosystem + market share, potentially putting long-term pressure on model-provider margins.

Positive note: Lower inference costs can expand AI use cases and token consumption, supporting broader demand for GPUs, cloud infrastructure, networking equipment and data centres.

Key Event

FOMC Minutes — July 28–29 meeting, released at 2:00 PM ET

The Fed kept rates at 3.50%–3.75% at its last meeting, but three of 12 voting members supported a rate hike. Markets will therefore focus closely on how hawkish the committee really is.

Given recent increases in oil prices and long-term Treasury yields, any stronger language around inflation, further rate hikes or keeping rates higher for longer could increase volatility in technology stocks.

Earnings

Today: Target (TGT), Lowe’s (LOW), TJX

Upcoming: Nvidia (NVDA) reports Q2 FY27 earnings after market close on August 26, one of the most important upcoming catalysts for the AI sector.

Today’s Market Focus

The key question is whether the FOMC minutes can ease concerns over long-term interest rates.

If the Fed sounds less hawkish than feared and Middle East tensions do not worsen, recently sold-off semiconductor and AI stocks could stage a technical rebound.

However, if the US 10-year Treasury yield moves back above 4.75% and approaches 5%, high-valuation technology stocks could face another round of deleveraging and valuation compression.
