Gold was mostly unchanged on Tuesday, after dropping over the past two sessions, as investors remained cautious ahead of a Federal Reserve meeting that starts later in the day.
The US central bank is widely expected to stand pat on policy but investors were bracing for any possible signals from the Fed about a tightening later this year.
Gold is highly sensitive to rising rates, which lift the opportunity cost of holding non-yielding assets such as bullion, while boosting the dollar in which the precious metal is priced.
Spot gold was at $1,315.51 an ounce at 0320 GMT, hovering above the previous session's close of $1,315.15. US gold dipped 0.3 per cent to $1,315.60 an ounce.
"At this moment people ... are more conservative on the likelihood of an interest rate hike as well as further stimulus. That would induce further correction in gold prices,” said Mark To, head of research at Hong Kong's Wing Fung Financial Group.
Spot gold may retest a support at $1,313, a break below which could cause a loss to the next support at $1,298, Reuters technical analyst Wang Tao said.
Holdings of SPDR Gold Trust, the world's largest gold-backed exchange-traded fund, fell 0.46 per cent to 958.69 tonnes on Monday.
"We are quite nervous about the precious group here, as barring a sharper sell-off in US equities, we suspect that the pressure on gold will only intensify between now and Wednesday," said INTL FCStone analyst Edward Meir in a note.
"We suspect the (Fed) statement alone will not be enough to change perceptions about a stronger dollar or dent expectations about rising rates.”
US federal funds futures fell to four-week lows on Monday, signalling traders raised their bets the Fed would raise short-term interest rates by the end of 2016 if the economy shows further improvement.
Asian markets remained cautious with investors waiting for cues from the two-day Fed meet, sending the safe-haven yen higher, while a fresh skid in oil dampened energy stocks on Wall Street.
The dollar edged down 0.1 per cent versus a basket of six major currencies, below the previous session's high of 97.569, its loftiest since March.
Among other precious metals, palladium fell 0.7 per cent to $679.72 after touching a nine-month high on Monday. Both silver and platinum inched up 0.3 per cent to $19.59 an ounce and $1,081.30, respectively.
