〔Overnight Brief〕Dollar Holds ~100 as Soft US Data vs Fed Hawks Set Up September Pivot, While Broadcom's $370B AI Guarantee Sparks 20% Rout - Yen Intervention Sixth Round Fails to Stick

1. Dollar and Fed: Cooling Data vs Hawkish Tail

• **[NEW] CICC:** US employment, wages, and underlying inflation have moderately cooled; current data makes it hard to support further Fed hikes, yet the Fed hasn't explicitly closed the hiking option and some officials retain conditional tightening ^[1].
• July CPI rose 0.1% m/m, PPI was flat, while retail sales fell 0.6% m/m and the control group 0.4% m/m, adding to signs of demand slowdown ^[1].
• CICC sees the dollar oscillating around 100 short-term; if data continue cooling, a break below 99 toward 98 is possible, with September FOMC as the likely policy node ^[1].
• **[ONGOING] Guan Tao:** The US-Japan joint intervention on July 30-31 is a continuation of the Plaza Accord framework, not a new departure; the past five rounds of interventions (since 2022) have been "more failures than successes" ^[2].

2. AI Financing Risk: Broadcom's $370B Guarantee Sparks Selloff

• **[NEW] Bank of America credit analyst Tom Curcuruto** downgraded Broadcom's bond rating from overweight to market weight on August 11, citing a $370B maximum residual value guarantee (RVG) exposure in its "AI XPV Platform" financing arrangement by mid-2029, with a theoretical maximum loss of $42B if all clients default ^[3].
• Broadcom shares fell nearly 6% in three days, dipping below $400, a over-20% drawdown from June's high ^[3].
• **[NEW] Morgan Stanley** highlights Nvidia's neocloud funding as a potential significant revenue stream, suggesting divergent views on AI capital intensity ^[4].

3. China Markets: Index Expansion and Broker Optimism

• **[ESCALATED] Hang Seng Tech Index** proposed revision expands constituents from 30 to 50, with AI as a standalone theme and a dual selection mechanism (40 by market cap, 10 by revenue growth); CITIC estimates ~36 billion HKD passive inflows on inclusion, with ~28.5 billion HKD from market-cap group and 7.5 billion HKD from revenue-growth group ^[5].
• **[NEW] Guotai Haitong** argues China stocks will gradually enter a "golden autumn market" as tail risks are removed, policy is friendly, and overseas AI/cloud capex outlook improves (RPO strong) ^[6].
• **Huatai Securities:** Upward trend remains intact; AI chain preferred (communications equipment, domestic compute, AI power), with CXO leaders, nonferrous, and export chain as secondary; dividend bottom position (banks, transport) ^[7].
• **CITIC Securities** warns of factors limiting valuation expansion: US-China trade friction, FX losses in earnings season, and crowded AI pricing; the momentum may slow ^[8].
