USD/ Holdings of SPDR Gold Trust GLD, the world's largest gold-backed exchange-traded fund, rose 0.2% to 1,000.21 tonnes on Monday from 998.17 tonnes on Friday. By Eileen Soreng Sept 14 (Reuters) - Gold prices inched lower on Tuesday, as investors braced for the U.S. inflation data that could offer cues on the Federal Reserve's timeline to start tapering stimulus measures meant to aid economic recovery from the pandemic. "A modest acceleration (in inflation) reinforces the idea that the Fed is likelier to make a more formal announcement that a taper is imminent," said DailyFX currency strategist Ilya Spivak.
