Aug 25 (Reuters) - Gold eased on Tuesday after touching a more than three-month high earlier in the session, as profit-taking and a firmer dollar curbed gains ahead of U.S. inflation data and remarks from Federal Reserve Chairman Kevin Warsh this week.
Spot gold was down 0.2% at $4,640.40 per ounce by 1128 GMT, after hitting its highest level since May 14. U.S. gold futures were steady at $4,696.10.
"Gold's move today is primarily due to profit taking, with the dollar recouping some of last week's losses that followed the buyback announcement," Saxo Bank analyst Ole Hansen said, referring to the U.S. Treasury Department's decision to double the size of liquidity support buyback operations for longer-dated notes and bonds.
"The reasons why investors are falling back in love with gold again have not gone away and will likely continue to support in the coming months," Hansen added.
After falling to a more than three-month low after the Treasury buyback announcement, the dollar regained some strength on Tuesday amid a revived debasement trade, making greenback-priced bullion more expensive for buyers overseas.
Markets are now looking to the U.S. Personal Consumption Expenditures inflation report on Wednesday, along with the debut speech by the Fed's Warsh at the annual Jackson Hole symposium on Friday to further gauge his monetary stance.
Traders are currently pricing in a 40% chance of a U.S. interest rate hike in September, and a 60% chance that the Fed will leave rates unchanged, according to the CME FedWatch Tool.
A high interest rate environment tends to diminish bullion's appeal to investors as it does not yield any interest.
Meanwhile, gold-backed ETFs attracted inflows of 46.7 metric tons ($6.4 billion) last week, the largest weekly demand in 10 months, according to the World Gold Council.
On the geopolitical front, Iran vowed to retaliate against expanded U.S. economic sanctions that the Americans said would cut off Iran's economic lifeline.
Spot silver fell 1.3% to $68.03 per ounce, platinum dropped 1.4% to $1,849.18, and palladium was down 2.2% at $1,327.50.
