China's consumer prices showed further signs of stabilization in September, as core inflation reached its highest level in 19 months, underscoring a gradual strengthening in domestic demand.

According to data released by the National Bureau of Statistics on Wednesday, the core consumer price index, which excludes food and energy prices, rose 1 percent year-on-year, marking the fifth consecutive month of acceleration and the strongest increase since February 2024.

The headline CPI also showed a positive trend - logging a 0.1 percent month-on-month increase from a flat August and narrowing its year-on-year decline to 0.3 percent, compared with a 0.4 percent drop in August.

Meanwhile, the country's producer price index, which measures costs for goods at the factory gate, went down 2.3 percent year-on-year in the previous month, according to the data.

The decline narrowed by 0.6 percentage points from the previous month, suggesting an improvement in industrial demand amid government efforts to bolster economic growth.

On a monthly basis, the PPI held steady in September after a 2.9 percent year-on-year decrease in August, the bureau's data showed.

For the first nine months of the year, the PPI was down 2.8 percent compared to the same period in 2024.
