〔Overnight Brief〕ECB Lifts to 2.50% as US PPI Hits 5.4% and 30Y Mortgage at 6.85% One-Year High; PBOC Front-Loads ¥60bn/Day into China's Completed-Home-Sales Reset - Funding Cost vs Liquidity Cushion

0. Weekly Arc

The completed-home-sales mandate, issued by the housing ministry and two other agencies, has redrawn the land-auction playbook within days: Beijing, Shanghai, Shenzhen, Guangzhou and Xi'an have cleared first-round lots, and developers are shifting from turnover-and-scale math to single-project economics ^[1]. Yet the global rate tape is the binding constraint — ECB at 2.50% with 2027-28 inflation upgrades, US PPI at 5.4% and a 30-year mortgage at 6.85% together push the marginal global funding rate higher even as China's PBOC front-loads ¥60bn/day of overnight reverse repos to absorb a ~¥633bn government-bond settlement week ^[1][2][3]. Net: a domestic liquidity cushion deployed against an overseas funding-cost headwind, with Tuesday's August data cluster as the next pivot ^[4][5].

1. Policy Narrative

• **[NEW] Housing ministry + two agencies, completed-home-sales regime:** new land parcels must sell as completed homes; pre-sale projects must reach structural top-out ^[1]. First-round land auctions in five tier-1/new-tier-1 cities already show "differentiated, restructured" outcomes, with location, amenities, floor-area ratio and product fit replacing turnover as the underwriting axis ^[1].
• **[NEW] PBOC liquidity operations:** overnight reverse repos, fixed-rate volume auction, max ¥60bn/day, Sept 14-17; mirrors the August pattern of pre-tax-period front-loading ^[2]. Interbank overnight rate held at 1.35-1.40% ^[2]. A separate ¥500bn buyback-style reverse repo matures on Sept 14, with the market expecting rollover on Sept 15 to ease the combined tax-period and government-bond settlement pressure ^[2].
• **[ESCALATED] ECB +25bp to 2.50%:** second 2026 hike, with simultaneous upgrades to 2027-28 inflation projections ^[3]. Single-source research note; flag until the official ECB statement is re-confirmed.
• **[NEW] US Treasury $6bn long-end buyback; Bessent on JPY:** Treasury Secretary Bessent signaled an active stance on yen intervention alongside a $6bn long-end repurchase program ^[3]. Single-source macro note.
• **[NEW] China-US trade track:** the Ministry of Commerce said both economic teams are consulting on a $30bn reciprocal-tariff framework ^[3].

2. Key Data and Market Read

• **[NEW] US August CPI +3.4% YoY:** matched expectations and prior ^[3].
• **[NEW] US August PPI +5.4% YoY vs +5.3% expected; core PPI +4.6%:** services-side hot, ahead of consensus ^[3].
• **[NEW] US August existing-home sales 3.98M units, -2% MoM; 30-year mortgage rate 6.85% one-year high ^[3].
• **[NEW] China August exports +25.0% YoY vs +21.9% expected; imports +28.2% YoY vs +28.1% expected ^[3].
• **[NEW] China August CPI +0.8% YoY; PPI +3.8% YoY ^[3].
• **[NEW] China August manufacturing PMI 49.8% (+0.6pp MoM); non-manufacturing 49.0% (flat); composite 49.5% (+0.2pp) ^[5].
• **[NEW] First Financial Chief Economist Confidence Index 50.1:** back above 50 for the first time in three months ^[5].
• **[NEW] PBOC gold buying:** 22 consecutive months; June +480k oz, July +640k oz, August +650k oz ^[3].
• **[NEW] Poland central bank gold reserves 648 tonnes, reaffirms 700-tonne target ^[3].
• **[NEW] ECI weekly reads:** supply 50.17% (+0.01pp WoW), demand 49.95% (+0.01pp), investment 49.99% (+0.02pp), consumption 49.76% (-0.01pp), exports 50.18% (+0.03pp) ^[6].

3. Upcoming Catalysts

• **Tuesday Sept 15:** China releases August industrial production, retail sales, fixed-asset investment; the National Energy Administration releases August electricity consumption; NBS press conference ^[4][7]. First Financial's surveyed August industrial production mean is +4.7% YoY vs July's +4.5% print ^[5].
• **Monday Sept 14 (Beijing time):** RBA Assistant Governor Hunter fireside chat; Japan July industrial-production final; State Council Information Office briefing on SME payment-collection difficulties, featuring MIIT Vice Minister Ke Jixin, plus the PBOC, SASAC, SAMR and CSRC; ECB Executive Board members Isabel Schnabel and Piero Cipollone both on the wires; Canada August CPI ^[8][7].
• **Property "Golden September" test:** primary-market momentum still soft, secondary bottoming but listings ticking up; 18-city secondary transaction area may turn YoY-negative in September ^[9][6].
• **Shanghai SASAC (Sept 13):** held a symposium on improving supervisory mechanisms for district-level state-owned enterprises ^[10].

4. Contrarian and Tail Risks

• **Completed-home mandate has a contrarian read:** a commentary piece argues the "828 New Policy" tightens developer cash cycles but, by standardising the product and the funding gap, also makes the industry more financialised, not less ^[11]. Flag as opinion, not policy.
• **Live contradiction on China consumption:** the First Financial confidence index crossed back above 50, manufacturing PMI rose 0.6pp, and August exports beat consensus ^[5][3]; yet a separate commentary argues China's household consumption rate is structurally low and a step-change is unrealistic given property drag, employment pressure and demographics ^[12]. Both can be true on different timeframes — quote the data and the caveat together.
• **Source quality control:** the ECB +25bp-to-2.50% line, the US Treasury $6bn buyback, the Bessent JPY-intervention signal, plus the entire US August CPI/PPI/existing-home/mortgage cluster, all appear only in a single Chinese-language macro research note ^[3]; the "completed-home-sales are more financialised" read is a single opinion column ^[11]; treat the cluster as one fragile signal until the official ECB statement and a second tape confirm.

5. Micro and Sectoral Reads

• **[NEW] Mongolia-China energy/infra:** during inspection of the Erdeneburen hydropower station, Mongolian President Khurelsukh pledged continued deepening of energy and infrastructure cooperation with China ^[13].
• **[NEW] Wuhan 2028/2030/2035 innovation plan:** the Wuhan municipal committee's 14th plenum (13th session) approved a "Three-Step" plan to build a globally competitive innovation ecosystem: 2028 milestones on factor aggregation and institutional completeness; 2030 on collaborative maturity; 2035 on full completion as a central-China innovation pole ^[14].
• **[NEW] Data-asset national standards (GB/T 47949-2026, GB/T 47950-2026):** effective Sept 1, 2026; drafted by the Ministry of Finance; address the unique non-rivalrous property-rights problem of data as a factor of production ^[15].
• **[NEW] Hermès Executive Chairman Axel Dumas:** named pork prices as a discretionary signal for Chinese consumer recovery; H1 results show consumers spending on professional sports/services while pulling back on celebration categories ^[16].
