数据点评 | 通胀回升的三大因素（申万宏观·赵伟团队）

Core Viewpoints - The inflation rebound in October is primarily driven by factors other than the anti-involution effect, with significant contributions from commodity price increases [2][60] - The Consumer Price Index (CPI) rose to 0.2% year-on-year, up from -0.3% previously, while the Producer Price Index (PPI) decreased by 2.1% year-on-year, showing a slight improvement from -2.3% [9][59] Factors Influencing Inflation - Factor One: The anti-involution effect has led to an increase in coal prices, but its impact on downstream PPI is limited. In October, PPI increased by 0.1% month-on-month, with a year-on-year improvement of 0.2 percentage points to -2.1%. The significant rise in copper prices, which increased by 7% month-on-month, was a major contributor to the PPI increase [2][10][60] - Factor Two: The CPI's rise above zero is attributed to a low base and reduced supply in certain food categories, which pushed food CPI up. The year-on-year food CPI improved by 1.5 percentage points to -2.9%, with fresh vegetables and fruits seeing increases of 6.4 and 2.2 percentage points, respectively [2][17][61] - Factor Three: Core CPI continued to rise, supported by improved travel demand and rising gold prices. In October, core CPI increased to 1.2% year-on-year, with significant price increases in accommodation, airfares, and tourism due to the overlapping National Day and Mid-Autumn Festival [3][24][61] Future Outlook - The price increases in bulk commodities are expected to continue influencing inflation, but the anti-involution effect on downstream prices may take time to manifest. It is anticipated that the PPI will remain around -2.2% year-on-year in the fourth quarter, while the CPI's year-on-year increase may be limited due to the tapering of national subsidies and slow recovery in downstream PPI [4][37][62] Regular Tracking - The CPI showed a rebound, with contributions from both food and non-food items. In October, the CPI rose by 0.5 percentage points to 0.2% year-on-year, with food CPI at -2.9%, reflecting a 1.5 percentage point increase from the previous month [5][43][63] - Non-food consumer goods saw a decline in CPI for household appliances and communication tools, with respective decreases of 0.5 percentage points to 5.0% and 0.3 percentage points to 1.2% [5][48][63] - Overall service CPI increased, with core service CPI performing better than seasonal trends, rising by 0.2 percentage points to 0.8% year-on-year [7][52][63]
