London, Sept. 10 (BridgeNews) - U.K. factory gate prices fell slightly in August while manufacturers' input prices were also down, according to figures published by the Office for National Statistics on Monday. Unadjusted output prices fell 0.1% on the month, rising 0.3% on the year, while adjusted input prices fell 0.4% on the month and were down 2.3% on the year. Both figures were in line with market forecasts.
The ONS said that the monthly fall in output prices was because of cheaper petroleum products, while input prices were down on the month due to a combination of lower prices for imported metals and cheaper domestically-produced food. The input price fall of 2.4% from a year ago was the largest decline since May 1999.
