BENGALURU, May 20 (Reuters) - Gold steadied after two days of losses on Friday, but was set for its biggest weekly slide in eight weeks on the back of a firmer dollar and indications from the U.S. Federal Reserve that it could raise interest raise rates sooner than expected.
New York Fed President William Dudley said on Thursday there was a strong sense among the central bank officials that markets were underestimating the probability of policy tightening and that the Fed was on track for a rate hike in June or July. comments came a day after the minutes of the Fed's April meeting revealed that most policymakers felt a rate increase might be appropriate as early as next month. gold XAU= was little changed at $1,254 per ounce at 0647 GMT, near a three-week low of $1,244 reached in the previous session. The safe-haven metal is down 1.5 percent for the week, its biggest drop since the week ended March 25.
