JAPAN INTERVENING TO KEEP DOLLAR UP, BROKERS The Bank of Japan is continuing to intervene in the Tokyo market, buying small amounts of dollars to hold the unit above 149 yen, brokers said. They said the Bank is coming in when the dollar is around 149.05/10 yen, the same levels as New York's close yesterday and the midday close in Tokyo today. Dealers said the Bank of Japan is intervening in the market through both banks and brokers this afternoon. The central bank is checking selling orders through banks and placing matching buy orders, they said. The central bank started to intervene shortly after the market opened here in the afternoon, the dealers said.
