Gold held steady on Wednesday, hovering near a lifetime high around $1,778 an ounce struck in the previous session, but further gains could be capped by a rebound in equities after the U.S. Federal Reserve's vow to keep rates near zero.

"We'll wait and see if stocks markets will continue to stabilise, because if they will, then gold will drop down a bit," said a physical dealer in Hong Kong.

"But I think there's no change in sentiment for gold. Interest rates in the U.S. will be kept low in the next two years and it should benefit gold for the time being."

Premiums for gold bars remained steady in Singapore and Hong Kong, while dealers in Tokyo were offering excess gold bars to trading houses in Southeast Asia after record bullion prices triggered selling in Japan.

Gold bars were quoted at a discount of 25 cents in Tokyo.

"The general public has been selling back their gold, so that's why we are offering gold bars not only to Singapore, but also to other countries in Southeast Asia," said a physical dealer in Tokyo.

"Southeast Asia is still buying gold at this moment."
