BONN CONFIDENT OF MAINTAINING CURRENCY STABILITY U.S. Treasury Secretary James Baker met West German Finance Minister Gerhard Stoltenberg and Bundesbank President Karl Otto Poehl in Frankfurt on Monday, a Bonn Finance Ministry spokesman said. After the meeting the spokesman quoted Stoltenberg as saying he was confident that foreign currencies could be stabilised at around current levels. The meeting came after Baker criticised West Germany for increasing short-term money market interest rates. He had said the rise was not in line with the spirit of the Louvre accord aimed at stabilizing the U.S. dollar last February. The meeting had been arranged last week, the spokesman said. Baker, Stoltenberg and Poehl had agreed to pursue the policies agreed under the Louvre pact with reference to currency stability and monetary policy. Earlier on Monday the Bundesbnak injected liquidity into the West German money market in a move which money market dealers interpreted as an attempt by the West German monetary authority to curb interest rate rises. The spokesman described Monday's talks, which he called private, as very positive.
