TOKYO (Reuters) - Japan's wholesale prices rose 2.8% in September from a year earlier, data showed on Thursday, accelerating from the previous month in a sign of lingering inflationary pressure from raw material imports.
The rise in the corporate goods price index (CGPI), which measures the price companies charge each other for their goods and services, exceeded a median market forecast for a 2.3% increase and followed a 2.6% gain in August.
The yen-based import price index fell 2.6% in September from a year earlier, after a 2.5% gain in August, the data showed.
