Synopsis: China and Hong Kong shares slid on Friday and were headed for a weekly loss, as thin trading volumes, firming bets on a US Federal Reserve rate hike, and an oil price shock tied to the escalating US-Iran conflict weighed on risk sentiment across Asia.
The CSI300 fell 1.6%, the Hang Seng slipped nearly 1%, and the pressure carried through into Indian markets, where the Sensex and Nifty 50 both opened lower. The one bright spot: Tencent-backed Shanghai Enflame Technology’s blockbuster stock market debut.
China, Hong Kong Benchmarks Head for a Weekly Loss
China’s blue-chip CSI300 index dropped 1.6% by the lunch break on Friday, while the Shanghai Composite lost 1.8% to slip below the 3,900-point mark.
Hong Kong’s Hang Seng was down close to 1%. For the week, the CSI300 has lost 1.6%, and the Hang Seng has shed 3.5%, putting both benchmarks on track for a second straight weekly decline.
Onshore sentiment has been cooling for roughly a month, as investors booked profits following the record-breaking, AI-led rally earlier this year.
Liquidity has also thinned out: daily turnover in onshore equities has been hovering near its lowest level of 2026 this week. The tech-heavy STAR50 index bore the brunt, falling 3% to its lowest level since late April.
A Middle East Oil Shock Adds a Second Layer of Pressure
The Fed-rate narrative wasn’t the only story in play. Friday’s selloff also coincided with an escalation in the US-Iran conflict, which intensified over the past two weeks after a month of relative calm.
The US military has struck multiple Iranian oil tankers near the Persian Gulf and the Strait of Hormuz in recent days, while Iran has targeted US naval assets and warned tanker crews near Gulf ports to steer clear.
That has pushed Brent crude into roughly the $106–109 a barrel range this week, different trackers put it at slightly different levels through Friday morning, its highest since mid-May, and up more than 8% for the month.
Some regional coverage attributed Friday’s Hang Seng weakness more directly to this oil-driven risk-off move than to the Fed narrative that led the original wire reports; both pressures were clearly at work simultaneously rather than being mutually exclusive.
Metals Slide, Energy Stocks Buck the Trend
The selling in mainland China was led by non-ferrous metal shares, which slumped more than 6% as metal prices broadly weakened.
Zijin Mining Group was among the hardest hit, dropping 7.3%. Technology majors listed in Hong Kong fell 0.8% as the sector stayed sensitive to rising yields and rate-hike chatter.
Set against that, oil producers gained on the back of firmer crude prices, PetroChina rose 1.2%.
| Stock / Sector | Move (Friday) | Primary Driver |
|---|---|---|
| Zijin Mining Group | -7.3% | Broad selloff in metal prices |
| Non-ferrous metals (onshore) | -6%+ | Falling metal prices |
| Hong Kong-listed tech majors | -0.8% | Rate-sensitive tech weakness |
| PetroChina | +1.2% | Rising crude oil prices |
| Shanghai Enflame Technology | +188% to +206% (reports vary) | AI-chip IPO demand |
US PPI Data Firms Up Fed Rate-Hike Bets
Behind the rate-hike bets: US producer prices rose 0.4% month-on-month in August, matching consensus, but the annual PPI print accelerated to 5.4%, a tenth of a point above forecasts and up from July’s upwardly revised 4.8%.
Core PPI, which strips out food and energy, rose a softer-than-expected 0.2% on the month (4.6% annually), a mixed signal that gives both hawks and doves something to point to.
The headline strength was largely an energy story: final-demand energy prices jumped 4.2%, and diesel fuel alone surged 24.1% as the Iran conflict fed directly into fuel costs.
Following the data, CME’s FedWatch tool showed the probability of a 25-basis-point hike at the Fed’s September 15–16 policy meeting climbing to as high as 76%, up from around 62% ahead of the report.
The Fed’s benchmark rate currently sits at 3.50%–3.75%. BMO Capital Markets economist Scott Anderson noted that a hawkish tone from Fed Chair Kevin Warsh at Jackson Hole leaves the central bank little room to hold if the inflation data keeps pointing the same way.
Enflame’s ~200% Shanghai Debut Bucks the Broader Gloom
Against the broader weakness, Shanghai Enflame Technology’s listing stood out. The Tencent-backed AI chipmaker raised 6.12 billion yuan ($912 million) through its Shanghai STAR Market IPO, opening at 410 yuan versus its 142.18-yuan issue price.
Reported first-day gains vary by outlet and measurement point during the session; Reuters cited roughly 200%, SCMP reported 188%, and CNBC put it at 206%, so treat the precise figure as still settling rather than fixed.
Retail demand was intense, though the oversubscription figure also differs by source (SCMP cited about 4,073 times; other outlets cited figures as high as 6,000 times).
The jump valued Enflame at somewhere in the $26–28 billion range, roughly triple its pre-listing valuation.
The company remains unprofitable; it posted a net loss of 1.16 billion yuan in 2025, even as revenue grew 37% year-on-year. Enflame is the last of China’s so-called “four little dragons” of AI chipmaking (alongside MetaX, Moore Threads, and Biren) to go public, part of Beijing’s broader push toward semiconductor self-sufficiency as US export curbs squeeze Nvidia’s access to the Chinese market.
What It Means for Indian Markets: Sensex, Nifty Open Lower Too
The weak Asian cues and the oil shock carried straight through to Dalal Street. The BSE Sensex opened down 593 points (0.79%) at 74,309, and the Nifty 50 opened down 207 points (0.88%) at 23,270, both tracking Thursday’s close of 74,902.59 and 23,477.80, respectively.
These are opening-session prints; the full-day move may have shifted by the close. Brent trading near the $108 mark added extra pressure on India, a large net oil importer.
FIIs were net sellers of about Rs 438 crore in the previous session, while DIIs stepped in as net buyers of roughly Rs 1,026 crore, partly cushioning the fall.
Elsewhere in the region, Japan’s Nikkei 225 fell nearly 2.8%, and South Korea’s Kospi dropped about 2.5%, both sharper declines than China’s own benchmarks, underlining how the oil-driven risk-off mood hit harder outside China on Friday.

Frequently Asked Questions
Why did China and Hong Kong stocks fall on September 11, 2026?
A combination of thin onshore trading volumes, rising bets on a US Fed rate hike after a hotter-than-expected August PPI print, and an oil price shock from the escalating US-Iran conflict all weighed on sentiment together.
How much did the Hang Seng and CSI300 fall this week?
The CSI300 lost about 1.6% for the week and the Hang Seng was down roughly 3.5%, putting both on track for a second consecutive weekly decline.
Why did Shanghai Enflame Technology shares surge despite the broader selloff?
Enflame’s Shanghai listing drew heavy demand as part of a broader rally in Chinese domestic AI-chip makers, as investors bet on these firms replacing Nvidia amid US export restrictions; reported first-day gains ranged from about 188% to 206% depending on the source.
How are Indian markets reacting to the global selloff?
The Sensex and Nifty 50 both opened lower on Friday, tracking weak Asian cues and rising Brent crude prices, though domestic institutional buying partly offset the FII selling seen in the prior session.
