In the absence of any clear clues, gold prices barely moved on Tuesday, while the greenback and Treasury yields held firm ahead of this week's series of Federal Reserve speakers.

Spot gold muted at $1,938.78 per ounce, meanwhile gold futures was flat at $1,964.50 per ounce. 

The yellow metal experienced a significant run-up over the previous two weeks, but has since found it difficult to advance, particularly since the dollar and yields have held steady despite indications of slowing U.S. economic growth.

Investor interest in gold has been restricted due to expectations that the Fed will maintain rates at higher levels for an extended period of time. Recent labor and inflation data also indicate that the Fed must maintain its current restrictive monetary policy in the foreseeable future.

The market's attention is now firmly fixed on a number of Fed speakers this week who are anticipated to provide additional monetary policy indications before a decision on interest rates later this month.
