Gold prices edged lower on Wednesday as the dollar ticked higher after U.S. Federal Reserve Chair Janet Yellen hinted at a hike in interest rates in an upcoming meeting of the central bank. 

Spot gold fell 0.14 %, to $1,226.44 per ounce by 0257 GMT, while U.S. gold futures rose 0.17% to $1,227.50. Spot gold may break a support at $1,220 per ounce and fall more towards the next support at $1,213, according to Reuters technical analyst Wang Tao.

SPDR said on Wednesday it has been certified as sharia compliant, its latest effort to spur demand for bullion from investors in majority-Muslim countries. Holdings of the largest gold-backed exchange-traded-fund (ETF), New York's SPDR Gold Trust GLD, rose 0.50% on Monday from Friday.
