The dollar jumped higher against most major currencies Friday, responding to what analysts said were continued signs of mild inflation and a possible improvement in the nation’s trade deficit. Gold prices fell sharply in response to the stronger dollar and low inflation speculation. Republic National Bank in New York quoted gold bullion at $454.50 an ounce at 4 p.m. EST, down $12.50 from the same time Thursday.
