NEW YORK/LONDON, Sept 9 (Reuters) - Gold prices fell again on Friday as hawkish comments on U.S. interest rates from a top Federal Reserve official helped lift the U.S. dollar, and as buyers continued to cash in on this week's price rally.
Spot gold was down 0.67 percent at $1,329.02 per ounce by 2:18 p.m. EDT (1818 GMT), while U.S. gold futures GCv1 for December delivery settled down $7.1, or 0.53 percent, at $1,334.5 per ounce.
The metal stayed on track for a second successive weekly gain. Gold was 0.5 percent higher on the week, having jumped 1.8 percent to $1,352.65 an ounce on Tuesday.
Soft jobs and services data this week have dented expectations that ultra-low interest rates, a key support for non-yielding gold, will rise this year. But investors remained uncertain on the outlook for rates, however, with Fed officials recently taking a more hawkish tone.
"Gold and silver really came under pressure on renewed expectation that the Fed is actively pursuing an interest rate hike. Before it seemed like more of a long shot," said Phillip Streible, senior market strategist for RJO Futures in Chicago.
The dollar .DXY rose against a basket of major currencies after Boston Fed President Eric Rosengren said the U.S. central bank increasingly faces risks if it waits much longer to hike rates, pressuring gold. FRX/ speculation that the Fed would stand pat on interest rates after hiking for the first time in nearly a decade in December have helped push gold 26 percent higher this year.
"The problem with gold currently is that on the technicals side we've now twice been around $1,375-1,380, so if it gets back towards there, people are just taking profits," ABN Amro analyst Georgette Boele said.
Expectations for further policy divergence between the United States and the euro zone were dampened after the European Central Bank held off signalling a move towards further policy easing at a meeting on Thursday. FRX/
"The ECB's decision to leave policy unchanged may have refocused market participants on the possibility that the Fed sends a hawkish signal in the coming days before its pre-meeting quiet period begins next Tuesday," BNP Paribas (PA:BNPP) said in a note.
