Silver dithers after last week's advance

Silver prices wavered on Monday after locking in a profit last week, as the dollar fell earlier in the session to a five-week trough, underpinning the white metal. 

Silver last traded at $17.40 an ounce, compared to the opening of $17.32, with an intraday high at $17.45, and a low at $17.32. 

Silver's current wavering comes as markets await speeches this week from Fed officials to take clues about the future of monetary policy, after the Federal Reserve reaffirmed its gradual approach to raise interest rates in the last meeting.

The dollar fell earlier today after the G20 meetings, at which the U.S. administration objected to the free and open trade pledge and made clear its intent to weaken the dollar in order to compete globally, in turn helping silver hold on to its gains. 

The dollar index, tracking the greenback versus an array of six major counterparts, inched up to 100.33 from the opening of 100.29, with an intraday high at 100.36, and a low at 100.00.
