PPI转正需要什么样的物价条件？（国金宏观孙永乐）

Core Viewpoint - The article discusses the conditions required for the Producer Price Index (PPI) to turn positive, emphasizing the need for significant increases in commodity prices, particularly in the context of current economic conditions and historical precedents [3][4][9]. Summary by Sections Commodity Price Trends - Since July, major commodities have experienced a slight decline after a peak, with coal and black metals rising by 13.8% and 3.9% respectively by mid-August [3]. - The PPI is expected to show a year-on-year increase in August due to a low base last year, but it remains in negative territory for 34 consecutive months [3]. PPI Composition and Impact - The PPI consists of various components, with black metals, non-ferrous metals, crude oil, coal, and other goods contributing 13.6%, 7.3%, 16.7%, 9.3%, and 53.2% respectively [5]. - In the first seven months of 2025, crude oil, black metals, coal, and other goods negatively impacted the PPI by 1, 0.9, 0.5, and 0.9 percentage points, while non-ferrous metals contributed positively by 0.4 percentage points [5]. Price Requirements for PPI to Turn Positive - For the PPI to turn positive by the end of the year, the average month-on-month PPI from August to December needs to reach 0.43%, which is similar to levels seen during the 2016 supply-side reforms [8]. - Corresponding to this, prices for rebar, non-caking coal, copper, and crude oil need to increase by 11% from July levels, reaching 3580 CNY, 940 CNY, 88000 CNY, and 79 USD respectively [8]. - If crude oil and copper prices remain stable, rebar and non-caking coal prices would need to rise by approximately 20% from July averages to achieve a positive PPI [8]. Historical Context and Future Outlook - Historical examples show that significant price increases in commodities often require external factors, such as the 198% rise in non-caking coal prices in 2021 due to energy-saving measures [9]. - A more realistic scenario for PPI turning positive may occur in Q2 of next year, where a 4% increase in prices from July levels would suffice [9]. - However, after Q2 of next year, the low base effect will diminish, necessitating further conditions for PPI positivity, especially if crude oil prices continue to decline [9][11]. Demand Considerations - The analysis assumes that upstream price increases can be effectively transmitted to downstream sectors, which is contingent on sufficient demand [10]. - Weak demand, particularly in the real estate sector, has historically hindered price transmission, preventing the PPI from turning positive despite rising upstream prices [11].
