Tokyo, March 23 (BridgeNews) - Japan's February corporate service price index averaged 96.2 (1995=100), down 0.7% on the year and down 0.1% on the month, the Bank of Japan announced Friday. Year-on-year falls in the February CSPI surpassed a 0.3% drop in both December and January. The BOJ has said the CSPI continues to show small drop in the monthly economic and financial report for March released Wednesday. Japan's CSPI covers services provided to corporations in seven major sectors, including finance, based on trading volume. The BOJ said real estate, finance and insurance, communication and broadcasting, rental and leasing and other services helped lower the February CSPI on the year. Also, the BOJ said another CSPI, which is designed to measure the strength of domestic demand, fell 1.4% on the year in February, accelerating from a 1.1% drop in December and a 1.3% fall in January. This CSPI excludes regulated service charges, overseas freighting and travel charges and charges of some services which are very volatile. The BOJ has revised the past CSPI figures back to January 1985 by shifting the base year from 1990 to 1995 starting with the release of the November 1999 data. Also, the BOJ has revised the weighting of seven major CSPI components, reflecting changes in the structure of the Japanese economy. For example, the BOJ has increased the weighting of telecommunication charges, personal computer leasing charges and charges for financial services in the new data. As a result, the October 1999 index stood at 97.2 with the new base, which is equivalent to 102.0 with the old base. The domestic wholesale price index for February, released earlier, averaged 95.7, down 0.4% on the year and unchanged on the month.
