Dollar Drops As Traders Feel Jitters

The dollar fell against the Japanese yen Friday on concerns about trade friction and worries that Washington would limit the greenback’s appreciation.

Traders anxious to get a feel for how much more the dollar can climb against the yen - it has gained more than 50 percent since its post-World War II low in April 1995 - grasped at minor news and a later-denied comment by Federal Reserve Vice Chairman Alice Rivlin that the dollar would be allowed to only go so high to provide direction.

Against European currencies the dollar was generally lower, falling against the German mark on continued worries about a delay in the creation of Europe’s monetary union. Notably, the greenback gained on the Swiss franc.
