Hourly Brief | 2026-09-28 16:00 CST

Coverage window: Beijing Time 2026-09-28 15:00 to 16:00. Data sampling time: 2026-09-28 16:00 CST.

Today trading session: Monday. A-shares closed (Shanghai -1.67%, ChiNext -4.53%). Hong Kong stocks holidays (Mid-Autumn). US stocks holiday (National Day, resumes 10/8).

Core backdrop: Fed raised 25bp at Sept 16 vote to 3.75%-4.00%. US 10Y yield at new 2007 high. Middle East tension — Iran Strait of Hormuz, US-Iran talks stalled. RBA expected to raise rates 9/29.

This Hour’s Main Theme

The Sino-US Commerce Ministries announced reciprocal tariff reductions on ~$30 billion in products — the most significant new development this window, standing in sharp contrast to the day’s broad risk-off sentiment. A-shares closed at 15:00, ChiNext -4.53% with 4,500+ stocks declining; gold extended losses to $4,154 (-3.04%), silver crashed 5%. Compared to the previous issue, the core change is: last issue focused on “deleveraging alerts + APAC broad sell-off,” while this issue added a Sino-US trade easing signal that the market did NOT react positively to — after the tariff announcement (15:19), gold continued falling and southbound capital net-sold HK$5B, indicating that the current risk-off drivers (rates + oil prices + hike expectations) overwhelmed trade-easing support. Meanwhile, US-Iran talks stagnated again (15:53), WTI rebounded to $93, Brent near $100 — the inflation/rates thread kept pushing.

Market Snapshot

Change from previous period (15:00 sampling):

Key Incremental News

1. Sino-US Commerce: Reciprocal tariff cuts on ~$30B in products ⭐⭐⭐⭐⭐

15:19 Jin10 flash / Commerce Ministry: China and US agreed to reciprocally reduce tariffs on ~$30 billion in goods from each other. Commerce Ministry simultaneously released details on the “Sino-US Trade Council and ‘30B-for-30B’ reciprocal tariff framework.” Impact: This is the most important new event this issue, and the first substantive outcome from this week’s Sino-US summit. On the surface a risk-on signal, but the market reacted neutrally-to-negatively — gold did not bounce after the announcement, A-shares continued declining on light volume, southbound capital kept net-selling HK$5B. The reason: the market focused more on the “reciprocal” nature (each side cuts ~$15B, not one-sided concession) and uncertainty around implementation timing. Short-term, this is mid-to-long-term positive for export chains (machinery, textiles, consumer electronics) and Chinese ADRs, but the limited window before 10/8 US market open may not fully price it in.

2. A-shares close sharply lower: ChiNext -4.53%, optical communication/semiconductors lead declines ⭐⭐⭐⭐

15:04 Jin10: Shanghai -1.67%, Shenzhen -3.44%, ChiNext -4.53%, STAR 50 -4.06%. Two-market turnover significantly lower than last week. Optical communication/CPO sector declined 10-15% for the day, semiconductors down 4%+. Impact: Last A-share trading day before the National Day holiday; 4,500+ declining stocks reflect concentrated pre-holiday risk aversion. Optical communication/semiconductor leadership in declines mirrors last issue’s Singapore industrial output turning negative + Korean tech stock selloff — AI computing chain prosperity concerns are transmitting from data to prices. Declining volume suggests weak buying rather than panic selling; if no major overseas negative events before 10/8, technical oversold conditions could spark a rebound. Conversely, if Middle East or rate situations worsen → declines could deepen. Source: Jin10 flash.

3. US-Iran talks stall again, Brent crude nears $100 ⭐⭐⭐⭐

15:53 Jin10 deep report (ID 231173): Trump publicly rejected Iran’s proposed phased de-escalation plan; US-Iran talks stagnated again, markets quickly repriced “risk premium” into crude. Brent crude approached the $100 mark. Impact: This is an escalation of the 14:19 “Trump rejects Iran plan” report — last issue was at “diplomatic de-escalation expectations fading,” this issue confirms talks “stagnated again” with Brent reapproaching $100. WTI rebounded from $92.25 at 15:00 to $93.01 (+0.83%), indicating geopolitical premium was repriced in the afternoon. Impact on inflation narrative: oil prices back at highs → core inflation downside受阻 → Fed hike expectations persist → growth stock valuations under持续 pressure. Strategy: Brent at $100 is both psychological and technical resistance; chasing longs here has poor risk-reward. Source: Jin10 deep report ID 231173.

4. UK November hike expectations rise ⭐⭐⭐

15:10 Jin10: Rising oil prices are driving up market expectations for a Bank of England rate hike in November. Brent crude rose 2.3% at one point. Analysts at KCM Trade noted oil-driven inflation pressure may force the BoE to take preventive action. Impact: The UK is not a core market for this brief, but if the BoE hikes in November alongside the Fed and RBA (9/29), it would create a “late Q3–early Q4 consecutive hikes” pattern — rising probability of major central banks tightening in sync, which is additional pressure on global risk assets, especially growth stocks. If the RBA raises as expected to 4.60% (tomorrow 12:30 CST) → the rate curve steepens across the board. Source: Jin10 flash.

5. Huang renxun meets Korean chip chiefs in New York ⭐⭐

15:28 Jin10: Nvidia CEO Huang Jen-hsun, Samsung Electronics President Lee Jae-yong, and SK Group Chairman Choi Tae-won met in New York — their first meeting in about two months. Impact: Korean semiconductors (Samsung, SK Hynix) fell over 5% today; the meeting with Nvidia executives may involve AI chip cooperation and HBM demand discussions. Short-term, Korean tech declines already partially reflect AI computing chain prosperity concerns; if the meeting releases positive order/cooperation signals → 10/8 spillover to US semiconductors (NVDA, AVGO, TSM ADR) could help limit declines. But details need confirmation; currently only a potential positive catalyst. Source: Jin10 flash.

Market Assessment

Sino-US tariff cuts vs. risk-off: Why can’t easing hold up declining markets? The $30B tariff cut is this week’s biggest summit outcome, yet the market reacted flatly — gold kept falling, A-shares declined on light volume, southbound capital net-sold HK$5B. Assessment: The market’s core drivers right now are the triple pressure of “rates + oil + hike expectations,” which completely overwhelmed trade-easing positives. Specifically: high US Treasury yields → higher discount rates compress growth stock valuations; oil near $100 → inflation expectations persist → rising probability of synchronized Fed/RBA/BoE tightening; these two threads form the main logic of current risk-asset declines. Trade easing is a genuine positive but needs a favorable rate environment to be fully priced. Strategic implication: on 10/8, export-chain stocks and Chinese ADRs may strengthen independently on the tariff news, but index direction still depends on the Dallas Fed data and oil prices.

Gold: $4,150 is the多空 fulcrum, technically oversold but trend bearish. From intraday high $4,280 to $4,150.87, daily decline 3.04%; $4,200 has fully reversed from support to resistance. Assessment: $4,150–4,160 is a key support zone tested multiple times since 2026 (June low, August correction lows all nearby). Shanghai Gold Exchange T+D closed -2.88% at ¥900.35/g, consistent with spot gold’s decline, confirming domestic capital is also bearish. If $4,150 holds → short-term oversold bounce may reach $4,200–4,220; if broken → $4,100 has dense support below, could test quickly. Core contradiction: Trump rejects Iran plan → geopolitical premium stays + oil remains firm → inflation expectations rise → Fed holds higher rates longer → gold’s cost of carry increases. This chain is still in effect. But if the dollar’s “death cross” gets weekly confirmation → dollar’s medium-term weakness will provide a gold floor. Strategy: Do not chase shorts short-term — down 3% intraday, a bounce could come anytime. Long entries require $4,150 to hold first, then wait for stabilization signals (e.g., 15-min bottom divergence).

Oil: Selling pressure reappears above $93, $100 is the narrative inflection point. WTI rebounded from $92.25 at 15:00 to $93.01, Brent approaching $100. Assessment: WTI $90–92 is an effective support zone (tested multiple days without breaking), $93–95 is the range top. If Brent effectively breaks $100 → market narrative shifts from “supply disruption fears” to “demand recession fears,” and oil itself may top out. Currently, Qatar’s LNG force majeure to Pakistan extended to November → short-term supply tightness supports prices; but Libyan pipeline restoration and Trump considering diesel export bans → potential supply-increasing factors are also accumulating. Strategy: Oil is in a high-range oscillation; direction depends on Middle East talks and Dallas Fed data. Below $92 is relatively safe for longs; $93–95 is the range top; $100 is the trend divider — do not chase a $100 breakout, do not add at $92 dips.

Next Few Hours

Key validation conditions:

• Can gold hold $4,150 support (determines if further decline to $4,100 is imminent)
• Will Dallas Fed Business Activity come in below the 8.2 estimate (affects rate expectations and post-holiday US market open direction)
• Can Brent crude effectively break $100 (determines whether oil narrative shifts from “supply” to “demand”)
• Middle East talks: Saudi Foreign Minister meets Rubio (this week) — any breakthrough?
