The precious metal has fallen in five out of the last six sessions as expectations for the US central bank to push ahead with a rate increase this month ramped up.
Spot gold was down 0.2 per cent at $1,223.59 an ounce at 1230 GMT (6:00 pm in India), having earlier touched its lowest since February 15 at $1,222.29 an ounce. US gold futures for April delivery were down $1.90 an ounce at $1,223.60.
The metal slipped last week after comments from Federal Reserve Chair Janet Yellen that the Fed was poised to lift benchmark US rates were seen as cementing plans for an increase at the US central bank's March 14-15 meeting.
Gold is highly sensitive to rising US interest rates, as these increase the opportunity cost of holding non-yielding bullion, while boosting the dollar in which it is priced.
"We're now expecting seven rate hikes for 2017/2018, and I think that will put more pressure on gold," Natixis analyst Bernard Dahdah said, adding that the metal is likely to be sensitive to outflows from bullion-backed exchange-traded funds.
Holdings of the world's largest gold ETF, New York-listed SPDR Gold Shares, fell another 3.8 tonnes on Monday, adding to the previous session's 4.7 tonne decline.
