Gold inched up on Tuesday as the euro held on to gains on expectations the European Central Bank will refrain from a rate cut this week, and with robust physical demand in Asia underpinning prices.
Economists expect the ECB to keep rates unchanged at a meeting on Thursday, supporting the single currency, while the dollar index edged down, making greenback-priced commodities more affordable for buyers holding other currencies.
Asia's physical market has picked up so far this year, with buyers tempted by weaker prices and on demand ahead of the Lunar New Year, traders said.
The trading volume on the Shanghai Gold Exchange's 9999 physical contract shot through the roof on Monday, hitting a record of 19,504.8 kilograms, after double-counting transactions in both directions.

Gold is likely to stay on the backfoot ahead of clearer signals on the global economy, analysts said.
"In the short-term gold lacks momentum to push higher," said Chen Min, an analyst at Jinrui Futures in the southern Chinese city of Shenzhen.
"If we hear anything from the ECB suggesting a worsening outlook for the region's economy or future rate cuts, it will weigh on the euro and consequently weigh on gold prices."
