Hourly Brief | 2026-09-28 12:00 CST

Coverage window: Beijing Time 2026-09-28 11:00 to 12:00. Data sample time: 2026-09-28 12:00 CST.

Today trading day: Monday. A-shares noon session closed. Hong Kong stock market holidays (Mid-Autumn). US market holidays (National Day, resumes 10/8).

Core context: Fed fully voted to raise 25bp to 3.75%-4.00% on Sep 16. US 10Y yield at highest since 2007. Middle East: Iranian cruise missile attack on US vessels in Strait of Hormuz, US-Iran negotiations stalled. RBA expected to raise rates on 9/29.

Hour’s Main Theme

A-share noon session crash (ChiNext -4.32%) continues the morning panic; gold holds 4197 after probing 4191; the new variable is a China-US 30B equivalent tariff reduction framework—short-term bullish but details pending. Compared to the last issue, the theme adds a “China-US trade easing” hedge to the “rate resonance suppressing risk assets” narrative, but US futures still fell (Nasdaq -0.7%), meaning the tariff goodwill hasn’t yet been priced by overseas markets.

Market Snapshot

Change from previous issue (11:01 sample):

• Gold: ~4,197→4,197 (flat). Narrow range 4,191-4,200 between 11:00-11:59; 4191 was the day’s second-lowest.
• WTI: ~92.1→92.6 (+0.5, higher). Daily range 91.4-92.9, modest upward drift.

Key Incremental News

1. A-share noon close: ChiNext -4.32%, over 4,800 stocks declined ⭐⭐⭐⭐⭐

11:37 Jin10: Shanghai Composite -1.74%, Shenzhen -3.37%, ChiNext -4.32%. Power sector bucked the trend (Zhejiang New Energy limit-up), tech stocks broadly sold off. Impact: Noon loss slightly widened from the morning -4%, confirming seller strength hasn’t exhausted. Power sector’s counter-trend strength aligns with the global rate-up narrative—higher rates mean more stable electricity demand expectations. Source: Jin10 flash.

2. China-US达成 30B equivalent tariff reduction framework ⭐⭐⭐⭐

11:15 Jin10: Ministry of Commerce announced the China-US Trade Council reached consensus on a 30B equivalent tariff reduction framework. Impact: The only substantive bullish variable today. If implemented → export chains (electronics, machinery, textiles) benefit. But “framework” ≠ final list; details await. Historical precedent: China-US trade negotiations from framework to implementation typically take months. Short-term sentiment bullish shouldn’t be over-extended. Source: Jin10 flash.

3. US futures down: S&P -0.4%, Nasdaq -0.7% ⭐⭐⭐

11:28 Jin10: S&P 500 futures -0.4%, Nasdaq futures -0.7%. Impact: US market holiday during National Day; futures are OTC/electronic quotes. Moderate decline suggests tariff goodwill partially offset by high-rate environment. Lower open likely when US markets resume 10/8. Source: Jin10 flash.

4. Offshore RMB overnight rate hits one-week high ⭐⭐

11:41 Jin10: CNH overnight HIBOR rose 9bp to 1.37152%, highest since Sep 21. Impact: Rising offshore funding costs typically reflect increased short-term RMB demand or tightening liquidity. Combined with A-share’s sharp drop, suggests possible foreign investor liquidation and currency conversion. Source: Jin10 flash.

5. SK Hynix starts Japan fab construction ⭐⭐

11:10 Jin10 (Korean SME Daily): SK Hynix began preliminary foundation work on a semiconductor fab in Japan’s Tohoku region. Impact: Global AI chip capacity expansion continues with geopolitical diversification. Impact on TSM/SKHY medium-term capacity dynamics; near-term price impact limited.

Situation Assessment

Global rate resonance remains the core suppressive force. Japan 2Y at 4.90%, 5Y at 2.430% record high; RBA likely to raise 9/29; Fed just completed a hike after Sep 16. Assessment: This multi-central-bank synchronous tightening cycle structurally压制es growth stock valuations. ChiNext’s single-day -4.32% is rare in A-share history, but global rate-anchor repricing is a key driver. Bearish stance unchanged: without a confirmed rate inflection, growth valuations lack systematic repair catalyst. Disconfirmation: If Dallas Fed Business Activity Index materially misses below expectations → recession trade intensifies → US yields fall → growth stocks may technically rebound.

Gold after 4200 breach. Gold oscillated narrowly 4191-4200, neither breaking lower nor reclaiming 4200. Assessment: Short-term weak oscillation; 4200 has flipped from support to resistance. Next technical support zone is 4180-4150, but Middle East geopolitics (Iran, Hormuz tension) forms a floor anchor. Strategy: avoid chasing shorts at 4195—daily already down 2%,短线 oversold probability exceeds continued sharp decline. If US yields peak after market open → gold may bounce to test 4220-4250.

China-US tariff framework: limited bullishness, don’t flip the thesis. 30B equivalent tariff reduction is a positive signal, but the gap from “framework” to implementation carries time uncertainty and risk. Assessment: Bullish for export chains, neutral for broader markets—the rate environment’s valuation压制 isn’t eliminated by a single trade event. If details exceed expectations → tech/export stocks may pulse higher, but sustainability doubtful.

Next Few Hours

Key observation points:

• 22:30 Dallas Fed Business Activity: The only US macro data this week, and the final风向标 before US markets resume 10/8. Below 8.2 → recession trade intensifies → yields fall → risk assets may rebound. Above expectations → rate-up narrative reinforced → global risk assets under continued pressure.
• National Day holidays (10/1-10/8) mean global markets are closed; information accumulation will be substantial, and resumed trading may see significant volatility.
