Asian shares, base metals and gold all gained as Spain announced a budget for 2013 based mostly on spending cuts that could be an effort to pre-empt the likely conditions of an international bailout.

"The euro zone crisis may have overcome one hurdle - Spain - but the overall situation is far from having a long term solution," said Victor Shum, managing director for downstream energy consulting at IHS Purvin & Gertz.
