SINGAPORE, June 27 (Reuters) - Gold prices held steady on Monday, aided by active buying on the physical market in Asia, while a stronger dollar weighed and investors awaited a Greek parliament vote this week that is crucial to securing a sovereign debt bailout.
Greece's parliament begins on Monday to debate a deeply unpopular austerity plan which international lenders are demanding to see approved this week to avert the threat of bankruptcy.
A parliament vote is expected on Wednesday, which will be closely watched by participants in the global financial markets.
"If Greece's parliament passes the austerity measures, it could be positive for risk assets such as commodities," said Ong Yi Ling, an analyst at Phillip Futures, noting that gold could be a beneficiary as it has closely correlated with moves in other commodities recently.
Although gold is seen as a safe-haven during times of economic stress, the increasingly grave debt crisis in the euro zone has done little to buoy appetite in gold recently. A weakening euro and stronger dollar have weighed on gold instead.
Spot gold was nearly flat at $1,498.45 an ounce by 0627 GMT, after falling 3 percent in the past two sessions, during which the 19-commodity Reuters-Jefferies CRB index declined more than 2 percent.

The dollar rose to its highest since June 16 against a basket of currencies, as the euro stayed under pressure ahead of the Greek parliament vote.
Gold is likely to weaken in the short term due to weak technical indicators and sluggish seasonal demand, but over the long run the outlook remains bright, analysts said.
"Towards the six-month horizon, prices should keep the uptrend we have seen since 2008," said Dominic Schnider, an analyst of UBS Wealth Management, adding that prices could target $1,600 in the second half of the year.
"Real interest remains in negative territory -- I think this remains quite supportive. And if you look at emerging markets, inflation remains stubbornly high."
Gold hit a record of $1,575.79 on May 2.
STRONG PHYSICAL BUYING IN ASIA
Asian buyers are snatching up bullion after prices fell to a five-week low of $1,491.90, pushing up premiums in Singapore and Hong Kong, dealers said.
"Prices have fallen $50 in the past few days and some people think it is an opportunity to buy, although we don't know whether prices have bottomed out," said a Hong Kong-based dealer, adding that premiums in Hong Kong increased 20 cents to between $1 and $1.50 per ounce over spot prices.
In Singapore, premiums have also gone up 20 cents to between 80 cents and $1, dealers said.
Spot silver dropped to $33.52, its lowest in more than a month, before recovering slightly to $33.67.
U.S. silver
Platinum group metals, used widely in industrial applications, fell in tandem with base metals.
Spot platinum fell to $1,662.24, its lowest since mid-March after a devastating earthquake and tsunami hit Japan. It recovered slightly to $1,669.74, down 0.2 percent.
The Relative Strength Index, or RSI, on spot platinum dipped below 30 for the first time since May 2010, suggesting the metal had been oversold.
Spot palladium declined to a one-month low of $720.88, before recovering slightly to trade at $721.28 -- down 0.8 percent.
