〔Overnight Brief〕$30B US-China Tariff Cut Clears and PBoC Floods Quarter-End as State Council Pledges More Tools - Cook's AI Capex Warning Lifts October Hike Odds to ~70%

0. Weekly Arc

The State Council, chaired by Premier Li Qiang, committed to stepped-up counter-cyclical policy, fresh relending quotas and a study of property/employment measures while MOFCOM disclosed a $30B US-China reciprocal tariff cut and the PBoC front-loaded MLF rollovers and reverse repo operations to smooth quarter-end and Golden Week liquidity ^{[1][2][3][4][5]}. The cross-border channel picture also widened: QFI access at three Chinese futures exchanges added 23 contracts from the 9/28 session, and a regulator letter formally confirmed that insurance institutions with Hong Kong Stock Connect stock-investment资格 can invest in Hong Kong Stock Connect ETFs ^[6][7]. Yet the external crosswind sharpened overnight as Fed Governor Lisa Cook reframed AI capex as a hike argument, with Fed funds futures pricing a ~70% October hike ^[8]. Net: a domestic stimulus stack and a trade détente against a global rate gap that the PBoC's cross-quarter easing cannot fully neutralize ^[1][2][8].

1. Policy and Liquidity

• **[ESCALATED] State Council Executive Meeting, chaired by Premier Li Qiang:** ordered an "加大宏观政策逆周期调节力度" step-up in counter-cyclical macro adjustment, pledged to deploy local government debt remaining quota, increase relending quotas for tech innovation, tech transformation, agricultural and small-business lending, and "research policies to stabilize the property market and promote employment and income growth" ^[5]. The meeting also flagged the "Six Networks" implementation plan, old reservoir and grain depot renovation, and faster bond issuance and use to advance 15th Five-Year Plan projects ^[4][5].
• **[NEW] PBoC quarter-end operations:** the central bank executed an early excess MLF rollover, raised the overnight reverse repo ceiling, and layered different-maturity reverse repos to meet quarter-end and National Day reserve demand; institutional consensus treats funding pressure as "overall controllable" given net government bond inflows and Q3-end fiscal spending, with post-holiday cash return expected to ease conditions, though late-October tax payment and OMO maturity overlap remains a watch item ^[1][2].
• **[NEW] QFI expansion:** the Shanghai, Zhengzhou and Guangzhou futures exchanges added 23 new futures and options contracts to the QFI access list from the 9/28 session, covering energy, metals, chemicals, agriculture and new energy ^[6].
• **[NEW] Sectoral follow-on:** MIIT and six other departments jointly issued the "15th Five-Year Plan" for the new battery industry, and the PBoC plus seven other departments issued guidance on financial support for the service sector's capacity and quality expansion, per the daily-briefing roundup ^[9].

2. Trade and the External Calendar

• **[NEW] $30B reciprocal tariff framework:** MOFCOM announced a US-China Trade Council framework with both sides agreeing on a "$30B for $30B" reciprocal tariff cut; the US will lower duties on ~$30B of Chinese imports - toys, home appliances, baby products, kitchen and bath items, and holiday gifts ^[3][10]. Implementation details remain pending, and listed exporters described the package as a "marginal positive signal" worth watching ^[3][10].
• **[NEW] China-US AI dialogue:** both sides agreed to hold the next AI dialogue by end-November, per the daily-briefing roundup ^[9].
• **[NEW] Commerce Minister Wang Wentao** held a video call with German Economy and Energy Minister Reiche on China-Germany and China-EU trade ties ^[11].
• **[ONGOING] Politburo member and Foreign Affairs Director Wang Yi** met Iwaya Takeshi, chair of the Japan Association for International Collaboration of Agriculture and Forestry, in Beijing, urging Japan to correct erroneous Taiwan-related remarks and to draw lessons from history ahead of the 80th anniversary of the opening of the Tokyo Trial ^[12].

3. FX and Cross-Border Capital

• **[NEW] CNH closed at 6.7127 versus USD** at the NY fixing on 9/28, up 100 pips from Friday's NY close and ending a four-session pullback; intraday range 6.7104-6.7263 ^[13]. Onshore CNY night-session close at 6.7118, +7 pips on the day ^[14]. The 9/28 central parity was set at 6.7399, up 90 bps versus the prior fix, with the onshore 16:30 close at 6.7131 the prior session ^[15].
• **[NEW] Insurance funds to Hong Kong Stock Connect ETFs (single-sourced to industry sources):** a "Regulatory Calibration Letter" formally confirmed that insurance institutions with Hong Kong Stock Connect stock-investment资格 can invest in Hong Kong Stock Connect ETFs under the same regulatory caliber; 31 stock-type ETFs were in the Hong Kong Stock Connect scope as of 9/27, described as high-quality, liquid constituents ^[7].
• **[NEW] RMB independent rally (single-source analysis):** a Yicai feature framed the CNY's decoupling from the USD rate path as the product of fundamentals, the settlement cycle and the regulatory framework - not just the carry differential - and asked whether Q4 strength can persist ^[15]. A separate Caixin headline dubbed the pattern "parallel tracks" ^[16].
• **[ONGOING] Japan FX:** senior MOF official Mimura Atsushi urged markets to heed warnings on the yen, per the daily-briefing roundup ^[9].

4. Industrial Earnings: The High-Tech vs Traditional Split

• **[NEW] August industrial profits above designated size +4.2% y/y**, down from July's 11.2%; January-August +15.7% ^[17][18][19]. August gross profit +7.5% y/y, +1.9 ppt versus July, signaling pricing power ^[17].
• **[NEW] High-tech manufacturing:** January-August profits +54.7%, 39 ppt above the all-firms average; the electronics and information industry posted +110% profit growth and contributed 62.0% of the all-firm profit expansion ^[17]. A Yicai editorial cautioned, however, that high-tech is "not yet effectively absorbing all the downside risk" flowing from weakening traditional industrial demand ^[17].
• **[NEW] Accounts receivable growth continued to rise** alongside the headline slowdown, a Caixin piece flagged ^[18].
• **[NEW] Pork prices stabilized:** national live pig 11.36 yuan/kg, -1.0% w/w; pork retail market 21.17 yuan/kg, flat w/w; pork wholesale 16.27 yuan/kg, -0.8% w/w and -15.7% y/y ^[20]. Experts expect prices to be "mainly stable" this week, with concentrated slaughter offsetting cautious downstream buying ^[20].

5. The AI Crosswind: Cook and the Cross-Asset Tape

• **[ESCALATED] Fed Governor Lisa Cook**, speaking in Oakland, delivered what is described as the Fed's sharpest quantitative warning yet on AI's inflation footprint: data-center investment has already lifted electricity and water costs ~5%, and only a "small portion" of the $2T committed AI capex has been spent, with the remainder set to compound price pressure ^[8]. Productivity gains are "expected to bring modest disinflation over the next few years" but "will not arrive in time to offset widening inflation pressures later this year" ^[8].
• **[NEW] Cook on transmission:** the AI-driven wealth effect is stimulating consumption, partially offsetting the modest disinflation from productivity gains ^[8].
• **[NEW] Cook on policy:** the Fed's earlier-this-month hike was necessary; the labor market can absorb further hikes; growth has been "notably resilient" over the past year ^[8].
• **[NEW] Market read:** Fed funds futures price a ~70% probability of an October hike ^[8].
• **[NEW] Cross-asset backdrop (single-wire roundup):** SpaceX's Starship achieved its first orbital insertion after engine issues; Nvidia added $150B to its buyback authorization, lifting the total to $235B; leading AI researchers called for regulation of self-improving AI; Qatar extended its LNG force majeure to November; the US and Iran will hold separate mediator talks focused on a revised 7-day Iran proposal; Trump is set to announce a $15B Iowa steel project ^[9].

6. What Would Falsify It and Source Quality

• The counter-cyclical stack is the main argument for a sustained RMB bid and a high-tech-led re-rating; the falsification test is whether the late-October tax/OMO overlap actually tightens funding, whether the $30B tariff cut produces a measurable order-book response in toys, home appliances, baby products, kitchen and bath, and holiday gifts, and whether Cook's $2T capex warning materializes in the Q4 CPI pipeline ^[1][3][8].
• Source quality: the CNH fix and Cook's October hike probability are corroborated across multiple wires ^[13][8][14]; the Hong Kong Stock Connect ETF insurance-fund channel is single-sourced to industry sources relayed by Wallstreetcn ^[7]; the 9/24 daily-briefing roundup consolidating SpaceX, Nvidia, LNG and Iran is a single wire ^[9] - treat as a cluster, not a point; the Yicai editorial and the QFI contract expansion are single-sourced within their respective wires ^[6][17].
