The precious metal has rebounded more than $35 from the low hit before the Fed policy announcement last Wednesday, while the dollar has fallen 1.7 percent.
"The dovish outlook ... following last Wednesday's Fed meeting is clearly still having an impact. This is likely to lure a number of speculative financial investors back into gold after this group massively reduced their net long positions in the run-up to the meeting," Commerzbank (DE:CBKG) said.
