JAPAN SEES HIGHER MONEY SUPPLY GROWTH THIS QUARTER The Bank of Japan said it forecast Japan's broadly-defined M-2 money supply average plus certificates of deposit (CDs) will rise by about nine pct in the current April-June quarter against 8.5 pct a year earlier. Unadjusted M-2 plus CDs rose a preliminary 8.8 pct in January/March 1987 compared with a nine pct rise a year earlier, it said. The bank said the forecast rise is due to an increase in floating deposits due to recent low interest rates and a shift to private banks from the Bank of Japan of 400-1,000 billion yen by the recently privatised Japanese Railways.
