HONG KONG, June 12 (Reuters) - Asian stocks tumbled to an eleven-week low on Thursday after oil prices jumped on a report showing tightening supply, adding to fears about rising inflation and higher interest rates around the world.
European shares were expected to follow suit and open slightly lower, according to financial bookmakers, potentially extending a string of six days of declines.
Financial companies such as Sumitomo Mitsui Financial Group <8316.T>, National Australia Bank <NAB.AX> and Cathay Financial <2882.TW> were under fire after a report that U.S. investment bank Lehman Brothers <LEH.N> may hunt for more capital after already raising $6 billion, raising questions about the overall health of the sector.
Meanwhile, oil's climb has made investors nervous about higher borrowing costs, especially after Federal Reserve Chairman Ben Bernanke earlier this week said the recent rise in oil has increased the chances that inflation pressures will grow.
"If oil prices were to stay at these high levels, that would impact demand in emerging countries, such as India, and hurt our exporters, while domestic demand here is almost hopeless," said Koichi Ogawa, chief portfolio manager at Daiwa SB Investments in Tokyo.
Japan's Nikkei share average finished down 2.1 percent at the lowest level in two weeks. Exporters with high-profile brands overseas, such as Canon Inc <7751.T> and Sony Corp <6758.T>, were among the heaviest weights on the index.
The MSCI index of pan-Asian stocks <.MIAS00000PUS> dropped 2.6 percent to the lowest since April 2, while a separate index of Asia-Pacific equities excluding Japan <.MIAPJ0000PUS> was off 2.9 percent to the lowest since March 25.

Several central banks in the region, including those in China, India, Indonesia and the Philippines, have already begun to tighten monetary policy to fight upward pressure on prices, even with the global economy slowing.
And companies and governments in Asia continue to cautiously pass on higher costs to consumers.
China's Shandong province, a major steel-making area, raised power tariffs for industrial users during peak hours as it faces a possible power shortage, giving a boost to utilities squeezed by surging coal prices. [

From a record high on Nov. 1, the MSCI Asia ex-Japan index is now down around 24 percent. The popular definition of a bear market is one characterised by a prolonged period of falling prices, usually by 20 percent or more.
In the last six months global investors have reduced their exposure to the region, which was only a year ago hailed for its high returns and low inflation.
Data from The Bank of New York Mellon, one of the biggest custodians of foreign assets in the world, showed that since January, flows of capital out of the Philippines and Hong Kong stock markets were among the largest in the world.
U.S. light crude prices <CLc1> fell $1.06 to $135.32 after rising around $5 overnight on a report showing U.S. stockpiles fell for the fourth straight week. Crude hit an all-time high above $139 hit last week.

]The U.S. dollar rose against the euro and yen, continuing to rally on investor confidence the Fed will be able to balance growth with mounting inflation pressures.
The dollar has been strengthening the most against Asian currencies as the view takes hold that central bankers in the region are behind the curve in battling inflation.
"Pledges to tackle actual or threatened inflation with tighter monetary policy can be a moderate currency support, but only in so far as investors have confidence in the message from policymakers and inflation is not undermining asset prices," said Patrick Bennett, Asia foreign exchange and interest rates strategist with Societe Generale in Hong Kong said in a note.
The euro tumbled 0.5 percent to $1.5477 <EUR=> and has remained in a range of $1.60 to $1.53 ever since mid-March. Against the yen, the dollar rose 0.4 percent to 107.27 yen <JPY=> and is up 12 percent in the last three months.
The dollar climbed to the highest since late February against the yen on Wednesday, bolstered by Bernanke's comments about containing inflation.
Bernanke warned markets the Fed will not be complacent as declines in the dollar helped to spur crude's around 40 percent climb so far this year.
