6月通胀：三大分化（申万宏观·赵伟团队）

Core Viewpoint - The inflation data for June shows a divergence between CPI and PPI, with CPI rising slightly while PPI continues to decline, indicating a mixed economic environment influenced by various commodity prices [2][8][69]. Group 1: Divergence in Commodity Prices - In June, PPI fell by 0.3 percentage points to -3.6% year-on-year, primarily due to declining prices of upstream commodities like coal and steel, while CPI increased by 0.1% year-on-year, supported by rising food prices and platinum [2][9][69]. - The decline in PPI was driven by oversupply in sectors such as steel, cement, and coal, which contributed to a 0.4% month-on-month decrease, while international oil prices provided some support to PPI, contributing positively from oil and copper prices [2][9][69]. Group 2: Core Commodity PPI and CPI Trends - Core commodity PPI remains at historical lows, reflecting the impact of tariffs and low capacity utilization in domestic downstream industries, with a slight recovery of 0.4 percentage points to -1% year-on-year [3][21][70]. - In contrast, core commodity CPI increased by 0.3 percentage points to 0.6% year-on-year, driven by consumer stimulus policies that have bolstered domestic demand, particularly in durable goods and household items [3][27][70]. Group 3: Service CPI Performance - Service CPI remained stable at 0.5% year-on-year, with core service CPI also holding steady at 0.8%, while rental prices showed weakness, with a month-on-month increase of only 0.1% [4][30][61]. - The overall demand for services has remained stable, but the rental component, which is a significant part of the service CPI, has not performed as well compared to previous years [4][30][61]. Group 4: Future Outlook - The combination of policy measures and recovery in domestic demand is expected to alleviate inflationary pressures, but significant downward pressure on commodity prices is anticipated in the second half of the year, with PPI expected to underperform CPI [4][35][70]. - Factors such as tariff disturbances, low global oil inventories, and weakened investment in real estate and manufacturing are likely to constrain commodity prices, while low capacity utilization in downstream sectors will continue to suppress PPI recovery [4][35][70].
