〔Day Digest〕PBOC's ¥159B Net Injection Meets ¥1T A-Share Turnover and Yiwu's Record ¥548.85B Export Print — Liquidity Lifeline vs Fed Hike Spillover

0. Daily Arc

Wednesday's macro tape carried three distinct impulses: a clear PBOC liquidity injection of ¥159B net ^[1], a record export print from Yiwu that breached ¥500B one month ahead of last year's pace ^[2], and a sharp turnover expansion in A-shares to >¥1T mid-session, +¥185.3B versus the same point a day earlier ^[3]. Yet heavy industry remains in contraction — August crude steel -3.7% y/y, cumulative -3.1% through August ^[4] — and the audit office is flagging that local carryover balances are still under-redeployed, e.g. ¥1.215B sitting in seven Hubei county fiscal accounts ^[5]. Net: domestic stimulus meets an external Fed-hike overhang ^[6].

1. Liquidity and Rates

• **[NEW] PBOC:** net injected ¥159B on September 17 via ¥162B 7-day reverse repos at 1.40% (unchanged) and ¥600B overnight repos, against ¥603B maturing ^[1]. The skew toward overnight repos points to short-end funding smoothing rather than a directional policy signal.
• **[NEW] MOF:** to auction a 182-day discount Treasury with ¥60B face value, interest accruing from September 24, 2026 to March 25, 2027 ^[7].
• **[ONGOING] (commentary, single source) Fed spillover:** an opinion piece argues the September Fed move is preventive rather than the start of a sustained tightening cycle, and that any spillover into CNY assets is manageable given domestic policy support and A-share tech alignment with global cycles ^[6].

2. Trade and External Demand

• **[NEW] Yiwu customs:** exports ¥548.85B in the first eight months, +12.8% y/y — a record high, breaching ¥500B one month earlier than 2025; imports ¥87.55B, +29.4% ^[2]. Total trade ¥636.40B, +14.8% ^[2].
• **[ONGOING] Green exports:** CCTV Finance reports domestic wind-turbine OEMs running heavy overseas order books, with lithium batteries cited alongside ^[8].
• **[NEW] Hainan offshore CNH bonds:** ¥5B in multi-tenor format (3-year sustainability, 5-year blue, 10-year) to list on HKEX on September 24 — the fifth consecutive year of Hainan CNH issuance in Hong Kong ^[9].
• **[NEW] Pinglu Canal:** first day of navigation (September 16) saw Nanning Customs clear 1,679.8 tons — auto parts, plywood, sodium sulfate, fiberboard ^[10]; Xinhua frames the waterway as a western "new artery" linking river and sea ^[11].

3. Equity Markets and Risk Appetite

• **[NEW] A-share turnover:** Shanghai/Shenzhen/BSE combined turnover exceeded ¥1T by mid-session, +¥185.3B versus the same point a day earlier; full-day projection ~¥2.3T ^[3]. Shanghai ¥469.4B, Shenzhen ¥523.3B, BSE 50 ¥7.5B ^[3].
• **[NEW] A-share fiscal data:** H1 2026 listed firms posted ¥37.76T revenue (+7.6%) and ¥3.58T net profit (+19.5%) per the China Association of Listed Companies report; taxes paid ¥2.53T (+4.5%), with the composite tax burden down 0.2pp to 6.7% ^[12].
• **[ONGOING] (single source) BeiDou:** the NDRC has targeted industry scale to break ¥1T within five years; the fifth BeiDou International Summit on September 15-16 in Zhuzhou was opened by Vice Premier Zhang Guoqing, who called for deeper integration with AI and satellite internet ^[13].

4. Property and Fiscal Coordination

• **[ESCALATED] Mortgage squeeze in Guangzhou:** the share of second-hand transactions using mortgage finance fell from 45.08% in June to 38.85% in July and 35.6% in August per the Guangzhou Real Estate Intermediary Association ^[14]. In Shenzhen, full-payment buyers reached 25.3% of H1 2026 second-hand transactions, +6.3pp y/y, per the Beike Research Institute ^[14]. Li Yujia, Chief Researcher at the Guangdong Provincial Housing Policy Research Center, frames the shift as household balance-sheet repair — buyers in tier-1 cities now have accumulated savings that can cover a rationally-priced unit outright ^[14].
• **[NEW] Hangzhou land:** one residential parcel in Gongshu District sold for ¥1.537B at a 6.22% premium, floor price 16,319 RMB/sqm versus 15,363 RMB/sqm reserve; the Zhongtian-Haiwei consortium won after nine rounds ^[15].
• **[NEW] Xi'an:** the housing provident fund policy was widened to allow renovation of owner-occupied housing, capped at ¥200,000 per case ^[16].
• **[NEW] Audit office:** recent provincial FY2025 audit reports flag un-redeployed carryover balances, contravening State Council rules that require multi-year idle balances to be reclaimed for priority uses ^[5].

5. Policy and Tail Risks

• **[NEW] State Council:** the General Office issued the Opinion on Further Strengthening the Full-Chain Safety Regulation of Fireworks and Firecrackers, mandating that any producer involved in a casualty incident be suspended, that licenses be revoked if non-compliance persists post-rectification, and that principal liability be pursued under an "investor-beneficiary-responsible" rule ^[17][18].
• **[ONGOING] Trade-in:** People's Daily Finance flags 129 million items in the consumer-goods trade-in program as a driver of services-sector migration ^[19].
• **Source quality control:** the Fed-spillover and BeiDou-trillion items are single-source commentary or wire pickups ^[13][6]; the Hubei audit figure is one example among several unnamed provinces in the ^[5] thread — treat as illustrative, not exhaustive. Falsifiable test: whether the PBOC extends net injection through Friday and whether Thursday's policy news corroborates the stimulus-tilted read ^[1][6].
