NAKASONE, SUMITA AGREE RATE CUT NOT APPROPRIATE Prime Minister Yasuhiro Nakasone today agreed with Bank of Japan governor Satoshi Sumita that a further cut in the discount rate was not appropriate at present, central bank sources said. They told Reuters the two discussed the subject at a routine meeting. Sumita told Nakasone he did not feel a rate cut was appropriate and Nakasone expressed his understanding, the sources said. Currency dealers have speculated that Japan and West Germany might come under pressure at next week's Venice summit to cut interest rates to boost their economies. Nakasone, but not Sumita, is due to attend the summit.
