Commodities bounded higher along with global stocks markets on Tuesday on fresh hopes that European leaders would iron out the region's debt problems.
Spot gold rallied 3 percent, snapping four consecutive sessions of losses as the weaker U.S. dollar helped battered commodities stage a comeback and U.S. crude oil prices rose nearly 5 percent.

``Commodity prices are up across the board. There's hopes a global recession can be avoided.''

``I think gold's bottomed out here,'' said Credit Agricole analyst Robin Bhar in London.
