Spot gold fell 1.6% to trade below $4,300 an ounce, dropping to $4,290.54 as investors monitored US-Iran diplomatic progress and Federal Reserve commentary.
A gauge of the US dollar rose to its highest level since July, adding downward pressure on bullion alongside concerns over potential further interest rate hikes.
Federal Reserve Governor Michael Barr stated that further interest rate increases are likely needed to return inflation back to the central bank's 2% target.
