Brussels, 08/06/2006 (Agence Europe) - At the ECOFIN Council on Wednesday, various EU finance ministers expressed concern about the potential negative impact on euro exchange rates of too large a rise in interest rates by the European Central Bank (ECB). Karl-Heinz Grasser, the ECOFIN President, hoped the single currency would hover between USD 1.20 and USD 1.30, but later added that he was not really very concerned about this. Germany's finance minister Peter Steinbruck urged the ECB to be cautious. On Tuesday evening, French minister Thierry Breton recommended vigilance to ensure the euro did not rise above what he described as a 'good' rate of USD 1.30. Spanish minister Pedro Solbes said the euro exchange rate was not at a level desired by himself or his colleagues. (See other article on ECB meeting in Madrid.)
