Gold soared past the $1,400 mark for the first time in a buoyant market boosted by speculative investors.
The spot price of gold rose to $1,403.88 before reaching a new all-time high of $1,407.20.
Gold was driven up by the Federal Reserve's decision last week to carry out a $600 billion monetary stimulus measure aimed at reviving the US economy, a move seen in some circles as liable to aggravate inflation.
Gold is seen as a safe haven in times of inflation.
Bullion normally moves inversely to the dollar, which fell to a nine-month low versus the euro last week.
