VIENNA, Dec 12 - European Central Bank Governing Council member Klaus Liebscher said on Friday that the euro was in line with its long-term average and that all central banks naturally took an interest in having a strong currency. When asked to comment on the euro's recent moves in foreign exchange markets, where it hit fresh records above $1.22 this week, Liebscher declined comment. But he did say the level now was not too far out of line. "The exchange rate that we currently have, without going into the daily rate, is one that is in line with long-term averages," Liebscher told reporters. "Every central banker will say that they are interested in a strong and stable currency," Liebscher added.||
