Comex gold futures were down around $6.00, or 0.5%, to $1,334.40 a troy ounce by 3:10AM ET (0810GMT). It fell to a one-week low of $1,332.80 in overnight trade.
Meanwhile, silver futures shed 6.2 cents, or 0.4%, to $17.06 a troy ounce, after tumbling 31.4 cents, or 1.8%, a day earlier.
Gold futures lost 0.9% on Monday as the dollar extended its rebound from a three-year nadir and benchmark Treasury yields cleared their highest level since April 2014.
The dollar continued higher, rising almost 0.3% against a basket of six major currencies to 89.44 in early trade, having pulled up from a low of around 88.25 set last week, its weakest level since December 2014.
U.S. government debt yields also extended recent gains, with the benchmark 10-year note climbing to its highest level in almost four years at 2.733%.
The Federal Reserve is not expected to take action on interest rates at the conclusion of its two-day policy meeting at 2:00PM ET (1900GMT) on Wednesday, keeping it in a range between 1.25%-1.50%.
The central bank will release its post-meeting statement as investors look for any change in language which could point more clearly to a rate hike in the months ahead.
This week's meeting will be the last under the leadership of Janet Yellen, before she is replaced by Fed Governor Jerome Powell.
The majority of economists believe that the Fed will hike rates in March, followed by another hike in June, with a third move higher arriving in December.
Gold is highly sensitive to rising rates, which increase the opportunity cost of holding nonyielding bullion.
