The euro is at new 8-month highs against the dollar amid expectations the Federal Reserve will loosen its monetary policy, which lowers the appeal of dollar assets, to help the economy.
The 16-nation euro rose to $1.3873 early Wednesday in Europe, up from $1.3859 on Tuesday and the highest level since Feb. 3. It rallied 7 percent last month and has already gained 1.5 percent so far in October.
Traders are wary of a global "currency war," in which countries try to weaken their currencies. Japan did so this week, as did Brazil, though European authorities are not expected to, which has helped the euro.
The dollar slid against the Japanese currency, to 83.07 yen from 83.18 yen on Tuesday. The British pound rose to $1.5932 from $1.5901.
