August witnessed a notable shift in China's price landscape, with the Consumer Price Index (CPI) reversing a previous decline to post a moderate increase, while the Producer Price Index (PPI) saw its year-on-year growth accelerate. These movements were attributed to a combination of international market fluctuations and seasonal factors affecting domestic food supply.

On a month-on-month basis, the national CPI transitioned from a 0.1% decrease in the prior month to a 0.4% increase in August. Year-on-year, the CPI growth rate rebounded to 0.8%, up from the previous reading. Meanwhile, the core CPI, which excludes food and energy prices, saw its annual growth edge up to 1.0%.

In the industrial sector, the PPI also turned around, moving from a 0.7% month-on-month decline to a 0.4% increase. This shift was fueled by rising international commodity prices and increased demand in certain industries driven by industrial upgrades, leading to a year-on-year PPI growth expansion to 3.8%.

Consumer Prices Reverse Course with a Modest Annual Rebound

Looking at the monthly data, the CPI's return to growth was largely driven by higher energy costs. Domestic gasoline prices surged 7.2% after falling 10.7% the previous month, contributing approximately 0.21 percentage points to the monthly CPI increase. Gold jewelry prices also rebounded sharply, climbing 7.6% following a 2.6% drop, which added another 0.04 percentage points.

The rapid growth in demand for computing power pushed up prices for mobile phones, tablets, and data storage devices by 2.3%, 2.1%, and 2.1% respectively, jointly contributing about 0.03 percentage points to the index. Food prices, which had been flat the month before, rose 0.4%, adding 0.07 percentage points to the monthly change. This was partly due to adverse weather conditions and seasonal transitions affecting vegetable supplies, with fresh vegetable prices increasing 5.5% month-on-month. Egg prices flipped from a 2.1% decline to a 2.4% increase, and pork prices rose 1.3%, with these three items together accounting for a 0.12 percentage point boost. Conversely, ample supplies of seasonal fruit led to a 2.5% price drop for fresh fruit, and the end of fishing moratoriums in some areas increased supply, lowering aquatic product prices by 0.9%, together shaving 0.07 percentage points off the monthly index.

Service prices increased at a slower pace, rising only 0.1% month-on-month, a moderation of 0.3 percentage points from July, contributing 0.04 percentage points. However, travel-related services continued to see price hikes during the summer holiday, with vehicle rental, airfares, and hotel accommodation up 3.3%, 3.0%, and 1.0% respectively.

Annually, the CPI rose 0.8% in August, an acceleration of 0.3 percentage points from July, primarily due to a widening in energy price gains. Energy prices jumped 4.1% year-on-year, up from 0.6% the previous month, contributing a noticeable 0.28 percentage points to the overall CPI and adding 0.24 percentage points more impact than the prior month. Gasoline prices specifically surged 9.3%. Industrial consumer goods, excluding energy, saw their prices rise 1.8% year-on-year, a slight acceleration, contributing 0.42 percentage points. Notably, gold jewelry prices soared 33.6% annually, and prices for tablets, computers, and mobile phones increased by significant margins.

Service prices saw an annual increase of 0.8%, contributing 0.38 percentage points to the index. Within services, travel service prices climbed 1.3%, and medical service prices rose 4.0%. Food prices, however, decreased by 1.4% year-on-year, exerting a downward pull of 0.24 percentage points. Pork prices fell 11.8% annually, though the decline narrowed, while prices for fresh vegetables, fruit, grains, edible oils, aquatic products, and dairy saw decreases ranging between 0.5% and 2.8%. Conversely, egg prices jumped 18.5% year-on-year, and mutton, beef, and poultry saw price increases.

Factory-Gate Prices Swing to Growth and Annual Gains Expand

The PPI's monthly turnaround in August was characterized by several key trends. First, imported inflationary pressures played a significant role. International crude oil and non-ferrous metal price increases filtered through to domestic industries, with oil extraction, refined petroleum product manufacturing, and organic chemical raw material manufacturing prices rising 10.4%, 4.1%, and 0.9% respectively. Non-ferrous metal smelting and rolling processing industry prices increased by 0.8%, with these four sectors collectively contributing approximately 0.31 percentage points to the monthly PPI rise.

Second, industrial transformation and upgrading boosted demand in specific sectors. Prices in electronic circuit manufacturing rose 3.5%, virtual reality equipment manufacturing increased 1.9%, and service consumer robot manufacturing saw a 0.3% uptick. Additionally, biomass fuel processing and comprehensive waste resource utilization industries both saw price increases of 0.3%.

Third, seasonal patterns influenced price movements. Increased demand for electricity and coal in August pushed up coal mining and washing prices by 2.8% and electricity supply prices by 1.4%. In contrast, hot and rainy weather hampered construction activity, leading to a 0.9% decline in ferrous metal smelting and rolling prices and a 0.2% dip in non-metallic mineral products.

On a year-on-year basis, the PPI rose 3.8%, an expansion of 0.3 percentage points from the previous month. Looking at key industries, coal mining and washing prices led the gains with a 26.6% increase, followed by non-ferrous metal smelting at 20.8%. Oil and gas extraction, petroleum, coal and other fuel processing, and chemical raw materials saw increases of 10.5%, 11.1%, and 9.1% respectively. Electrical machinery manufacturing and computer, communication and other electronic equipment manufacturing also recorded solid gains. These seven sectors together contributed approximately 4.24 percentage points to the annual PPI increase, a stronger upward pull than last month.

The largest downward pressures on the annual index came from electricity and heat production and supply, automobile manufacturing, non-metallic mineral products, pharmaceutical manufacturing, alcohol and beverage manufacturing, and agricultural food processing, with decreases ranging from 1.7% to 5.3%. These six industries collectively pulled the PPI down by roughly 0.74 percentage points year-on-year.
