国内成品油价三连涨，CPI仍难回暖

Group 1 - Domestic refined oil prices will increase again on July 1, following two price hikes in June, with gasoline and diesel prices expected to rise by 235 and 225 yuan per ton respectively [1] - The adjustment mechanism for domestic refined oil prices is based on the weighted average price of international crude oil over the past 10 working days, indicating that prices are adjusted every ten working days [1] - The cumulative adjustment of gasoline and diesel prices in the first half of the year has seen a decrease of 330 yuan and 315 yuan per ton respectively, despite the upcoming price increase [2] Group 2 - The Consumer Price Index (CPI) for the first five months of the year has shown a year-on-year decline of 0.4%, with refined oil prices categorized under the transportation and communication sector [2] - The increase in refined oil prices may not directly lead to a rise in CPI, as CPI changes depend on various independent factors, and the transmission of oil price increases to consumer goods and services may experience delays [2] - A substantial recovery in CPI is contingent upon domestic demand recovery, rather than solely on the increase in refined oil prices [2]
