* Bank tax expected to reduce annual earnings by 4.5 pct -analyst

SYDNEY, May 10 (Reuters) - Australia's biggest banks are likely to pass on the bulk of a surprise A$6.2 billion ($4.56 billion) tax to their customers in the form of higher interest rates rather than accept an earnings cut, fund managers and analysts said on Wednesday.
The government on Tuesday announced a six basis points levy on bank liabilities in a bid to raise about A$1.5 billion a year from the five biggest banks - Commonwealth Bank of Australia CBA.AX , Westpac Banking Corp WBC.AX , Australia and New Zealand Banking Group ANZ.AX , National Australia Bank NAB.AX and Macquarie Group MQG.AX - over the next four years.
The measure, which also aims to help smaller rivals compete with the banking oligopoly, comes into effect July 1 and was introduced by a centre-right government that has been defending the banks against calls for a wide-ranging inquiry into their practices. Stanley analysts said the levy would reduce the annual earnings of the big five banks by an average of 4.5 percent. Westpac said the financial impact of the levy was not immediately clear while representatives of CBA and NAB declined to comment. ANZ and Macquarie did not respond immediately to requests for comment.
"It is clear it is a tax on earnings," Karara Capital investment manager Rohan Walsh said. "I think (the banks) will make efforts to maintain the level of profitability and returns on assets."
Australian Bankers' Association Chief Executive Anna Bligh called the tax a "not a well thought out policy response to a public interest issue."
"It is a political tax grab to cover a budget black hole," she said in a statement.
Shares in the big banks fell by as much as 3 percent on Wednesday, having also declined on Tuesday. The broader S&P/ASX 200 index was up 0.5 percent in early afternoon trading.
Analysts said the banks could charge customers more to offset the tax costs. The banks may also try and overturn the measure: in 2010, the mining sector funded a campaign against a Labor government over a new resources tax that ultimately helped unseat Kevin Rudd, the prime minister at the time.
Treasurer Scott Morrison on Wednesday said the banks would be "offending their customers" if they raised mortgages because the levy was only imposed on liabilities such as corporate bonds, commercial paper, certificates of deposit and tier-2 capital instruments.
Arnhem Investment Management portfolio manager Mark Nathan said the banks did not view their funding sources as discreet cost pools in that way, which meant they were likely to raise rates on all customers.
"In so far that banks were able to hold their dividends prior to this I don't think that is going to be the straw that breaks the camel's back because they will pass most of it on," he added.
