〔Overnight Brief〕Four Futures Exchanges Lockstep on Programmatic Trading Rules While Post-Holiday Bond Rout Tests 1.6% 10Y, NEV Export Rebate Slashed to 9% — Supervision Tightens as Liquidity Eases

0. Weekly Arc

The overnight tape was defined by a coordinated regulatory move on the futures side ^[1] running counter to a deepening post-Golden-Week bond rally ^[2] and a fiscal-credit easing mix ^[3][4][5]. FTSE China A50 futures still closed 0.15% lower at 13,730 ^[6], and MOF cut NEV export VAT rebate from 13% to 9% from April 2027 ^[3][7]. Net: supervision tightens on derivatives while the front-end liquidity backdrop loosens — a split that decides the curve.

1. Cross-Exchange Programmatic Trading Rule Rewrite

• **[NEW]** Shanghai Futures Exchange (including Shanghai International Energy Exchange), Zhengzhou Commodity Exchange, Dalian Commodity Exchange, and Guangzhou Futures Exchange on Oct 12 simultaneously released drafts to revise violation-handling rules, with feedback due Oct 19 ^[1].
• **[NEW]** Mechanism: the revision implements the Futures and Derivatives Law and the Interim Administrative Provisions on Programmatic Trading, formally embedding algo-trading requirements into self-disciplinary codes ^[1].
• **[NEW]** Read: industry commentary frames the synchronization as a signal that algorithmic trading is now a frontline supervision scenario, with abnormal trading, high-frequency arbitrage, and cross-exchange order-book behavior facing unified identification and harder penalties ^[1]. The earlier "define–report–access–monitor" phase is now transitioning to a workable "violation–identification–penalty" stage ^[1].

2. Bond Market Post-Holiday Rout Extends

• **[NEW]** Guosheng Securities (Oct 11 report) flags three marginal supports for the rally: DR001 fell to 1.28%, breaking the lower bound of the June 1.3% area, which may signal greater PBoC tolerance for a lower short-end center ^[2]. Interbank CDs show net redemption, pointing to weaker bank funding demand ^[2]. Small/mid bank bond holdings growth has slowed, leaving room for later position-building ^[2].
• **[NEW]** PBoC's outright reverse repo rollover was oversized by 200 billion yuan, providing direct liquidity support ^[2].
• **[NEW]** Forecast: 10Y CGB yield to test ~1.6%, 30Y to ~2.0%, Q4 interbank CD rate to ~1.4% ^[2]. (Single-broker view; treat as a band, not a consensus.)

3. Tax, Credit, and Fiscal Mix

• **[NEW]** MOF/STA: NEV export VAT rebate cut from 13% to 9% effective April 1, 2027; e-cigarette device export VAT rebate cancelled ^[3][7].
• **[NEW]** PBoC Q3 MPC: emphasized counter-cyclical adjustment; on Sept 29 cut PSL by 25bp and added 200 billion yuan to sci-tech/tech-upgrade re-lending and 500 billion yuan to agribusiness/SME re-lending; on Oct 8 set out the RMB exchange-rate policy stance, reiterating no preset level and no intervention in long-term trend ^[4].
• **[NEW]** Export-Import Bank: Q1–Q3 new foreign-trade loans ~1 trillion yuan, up 9% YoY, with ~40% directed to trade-stabilizing entities and supply chains ^[5].
• **[NEW]** Yicai editorial recap of H1 fiscal execution: 1.25 trillion yuan in ultra-long special treasury funds for consumer trade-in drove over 1.1 trillion yuan in sales and benefited ~150 million participants; 2.07 trillion yuan in new special bonds supported 17,000+ projects; 1.91 trillion yuan in tax cuts/refunds for sci-tech and manufacturing; 1.73 trillion yuan in replacement bonds issued by end-July, completing 86.7% of the 2 trillion yuan annual debt-swap quota ^[8].

4. Activity Reads — Mixed

• **[NEW]** China Construction Machinery Industry Association: Jan–Sep excavator sales 214,274 units, up 23.1% YoY; September 22,717 units, up 14.4% ^[9]. Wheel loaders: Jan–Sep 117,077 units, up 24.9%; September 12,419 units, up 17.9% ^[9].
• **[NEW]** MIIT: September auto production 2.99 million, sales 2.956 million, down 8.7% and 8.4% YoY respectively ^[10].
• **[NEW]** CPCA: September NEV retail 1.084 million units, down 16.7% YoY ^[7].
• **[NEW]** September e-commerce logistics index 111.9, up 0.4 points m/m; 8 of 9 sub-indices rose, only cost index fell; seasonal apparel, travel gear, and consumer electronics cited as drivers ^[11].
• **[NEW]** National Tax Service: Golden Week service-consumption sales averaged +19.5% YoY, tourism/entertainment +23.6%; cross-regional personnel flows reached 2.142 billion trips over the seven-day holiday ^[12].
• **[ONGOING]** Healthcare: 245.4 billion yuan in tax cuts/fee reductions in support of health services in Jan–Aug, with 92.6 billion for medical services VAT exemption and 152.2 billion for community eldercare/childcare and health-insurance products ^[13].

5. External Sector

• **[NEW]** China-EU Trade and Investment Mechanism second regular meeting (Oct 8) produced 16 consensus outcomes covering trade/investment balance, export controls, IP, and WTO reform; hybrid car MoU reached; FSR technical dialogue agreed; pre-listing export-control notification mechanism established ^[14].
• **[NEW]** Goldman raised December Brent forecast by $5 to $90/bbl, citing Middle East supply risk ^[3].
• **[NEW]** Fed Cleveland President Beth Hammack: further hikes still possible, timing unspecified, preferring "small, more frequent" adjustments ^[7].
• **[ESCALATED]** Saudi civil aviation extended Riyadh airport closure to Oct 17 21:00 UTC ^[7]; Houthi claimed multiple strikes on Saudi facilities ^[15].
• **[NEW]** China-Laos Railway cumulative freight value topped 100.4 billion yuan across 20.77 million tons, with Kunming and Yuxi ranking #1 and #2 nationally for China-Central Asia train services in Jan–Aug (2,537 trains, 134,238 TEU) ^[16].

6. Q4 Policy Path and Falsifiable Tests

• **[NEW]** Huxiu commentary: the Q4 incremental policy package is largely set — 550 billion yuan quota carryover use, expanded structural tools, and ~10–20 billion yuan annualized mortgage interest subsidies ^[17]. Fiscal execution has been a weak link in 2026; Q4 will see catch-up ^[17]. (Single-opinion piece; flag as a view, not a government statement.)
• **[NEW]** Premier Li Qiang met Vietnamese National Assembly Chairman Tran Thanh Man in Beijing, signaling alignment on AI, clean energy, digital economy, and APEC/ASEAN/Lancang-Mekong coordination ^[18].
• What would falsify the bond-rally call: PBoC liquidity withdrawal or a surge in Q4 government bond issuance hitting the long end ^[2][17]. What would amplify the programmatic-trading crackdown's impact: an explicit penalty case under the new rule on a major participant ^[1].
