Oil prices rose again on Tuesday, extending a recent rally and providing support to regional energy stocks, while Wall Street provided a strong lead despite a weak manufacturing reading.
The euro held its own in early trade as investors keep tabs on a tour of Europe by Greece's new leaders aimed at ramping up support for a renegotiation of its massive bailout.
Crude enjoyed some much-needed buying after data showed the recent slump in prices has led to a decline in the number of rigs drilling.
US benchmark West Texas Intermediate for March delivery rose 36 cents to $49.93 while Brent crude for March rose 18 cents to $54.93.
The rises will come as welcome relief for markets after the black gold slumped more than 50 percent from its June 2014 peak owing to a global glut and a strong dollar.
Energy firms were the main winners from the rises. Hong Kong-listed Sinopec added 1.65 percent and CNOOC gained 3.50 percent, while in Sydney Woodside added 2.35 percent and Santos surged 3.75 percent. Inpex in Tokyo was 5.26 percent higher.
"There's a sense of security expanding among investors" as oil climbs, Toshihiko Matsuno, chief strategist at SMBC Friend Securities Co. in Tokyo, told Bloomberg News.
"The rise in prices has helped doubts about the global economic slowdown recede, and eased worry over default risk and downgrade risks for both countries and companies."
Regional stock markets were broadly higher. Shanghai rose 1.12 percent, Hong Kong added 0.24 percent and Sydney put on 0.23 percent, while Taipei gained 0.53 percent.
However, Seoul dipped 0.55 percent, while Tokyo eased 0.10 percent as the yen strengthened against the dollar.
The crude rally also lent support to Wall Street, where investors were able to brush off data indicating the US manufacturing sector slowed in January. While shares rose, there are fears that weakness in China, Japan and Europe is acting as a weight on the US economy, which also saw a sharp slowdown in growth at the end of last year.
The Dow rallied 1.14 percent, the S&P 500 jumped 1.30 percent and the Nasdaq added 0.89 percent.
The euro bought $1.1347 and 133.09 yen against $1.1343 and 133.43 yen.
