Gold prices scaled a near five-month high on Tuesday, driven by a weaker dollar and growing inflationary pressures, while investors awaited more US data to gauge the extent of global economic recovery.

Spot gold was up 0.1% at $1,910.24 per ounce by 0504 GMT.US gold futures rose 0.4% to $1,913.00.

"Gold prices are riding a very strong upward trend this is against the backdrop of a falling US dollar and also inflation concerns," said Margaret Yang, a strategist at DailyFX.

"Perhaps another fundamental factor behind gold is the return of Chinese and Indian buyers. In the near-term, if gold can breach the $1,922 per ounce mark, it can open the room for further upside potential."

The dollar index was down 0.2% against its rivals, making gold less expensive for other currency holders.

The US unit registered its second consecutive monthly loss.
