The dollar fell in hectic foreign exchange trading at home and abroad yesterday after President Carter's decision to freeze Iranian deposits in U.S. banks in response to Iran's plan to withdraw the money.
The price of gold, which usually rises when the dollar weakens because of the metals role as a hedge against monetary uncertainty, rose only slightly in New York and Europe.
Gold closed at $390 a troy ounce in both London and Zurich, up from $386.75 in London Tuesday and $387 in Zurich. In New York, it rose to $388 an ounce from $384 Tuesday.
