(Reuters) - Gold prices slipped on Friday and were headed for their sharpest weekly drop in 2-1/2 months as the dollar strengthened during the week.
Spot gold was down 0.2 percent at $1,328.90 an ounce as of 0338 GMT, heading for a fifth session of fall in six. It has shed 1.4 percent so far this week, its biggest since the week ended Dec. 8, 2017.
U.S. gold futures were down 0.1 percent at $1,331.2 per ounce.
"We remain somewhat cautious on gold over the short-term given that we think the dollar rally is still not over, especially in the light of U.S. Treasury yields remaining elevated," said INTL FCStone analyst Edward Meir.
The dollar index, which measures the greenback against a basket of currencies, was up 0.2 percent at 89.883. It reached a 10-day high of 90.235 on Thursday after hitting a three-year low of 88.253 late last week and was on track for a gain of almost 1 percent this week.

Meanwhile, Asian shares rebounded on Friday as comments from a Federal Reserve official eased worries that the central bank might raise rates more aggressively this year.
St Louis Fed President James Bullard tried to tamp down expectations of four rate hikes in 2018, instead of the widely anticipated three increases, saying on Thursday policymakers need to be careful not to increase rates too quickly because that could slow the economy.
The Fed started tightening its ultra-loose policy at the end of 2015 after keeping rates on hold for almost a decade. It raised interest rates three times in 2017 and is likely to tighten again in March.
