Asian shares rose, following a rally in US equities, and the euro hovered around multi-month highs on growing investor confidence of an agreement on spending and taxes between the White House and Republicans before the year-end deadline. Oil may get additional support if US inventory data is close to that of an industry group that showed a sharp drawdown.

Brent crude slipped 1 cent to $108.83 a barrel by 0150 GMT, after settling $1.20 higher. US oil slipped 2 cents to $87.91, after ending 73 cents higher and breaking above the 50-day moving average of $87.64.

"There is more upside potential for Brent because of a revival in the overall economic outlook," said Yusuke Seta, a commodities sales manager at Newedge Japan.

"Supporting factors are prevailing over negative factors."

Political manoeuvring intensified over an agreement to keep the US economy from tumbling off the "fiscal cliff" next year as Republicans tried to wring more tax-rate concessions out of the White House on Tuesday.
