Gold prices suffered losses in early trading on Monday for the second straight session as investors awaited economic data and comments from Federal Reserve officials this week for more clarity on the future direction of interest rates.

Update prices

Spot gold was down 0.5 percent at $2,671.49 an ounce by 0457 GMT, while U.S. gold futures were down 0.6 percent at $2,678.50 an ounce, according to Reuters data.

The dollar index rose slightly after gaining 0.6 percent last week against the euro in particular. A stronger dollar makes gold less attractive to holders of other currencies.

The precious metal is a hedge against inflation, but higher interest rates increase the opportunity cost of holding it.

As for other precious metals, silver fell in spot transactions by 0.4% to $31.16 per ounce, platinum rose by 0.6% to $973.99 per ounce, and palladium increased by 0.9% to $997.41 per ounce.
