* Barclays needs to raise 12.8 bln stg, taps investors for 5.8 bln
* Deutsche has earmarked 250 bln euros of assets that could be sold
* Investors fear more banks will need to raise capital
* UBS draws a line under its 2008 bailout with fund buyback
LONDON/FRANKFURT, July 30 A $9 billion rights issue and a fresh purge of assets are among the measures Britain's Barclays and Germany's Deutsche Bank announced on Tuesday to meet tougher rules on risk, raising concern among investors that regulators will push other European banks into similar action.
Unlike their U.S. rivals, which were quickly restructured and recapitalised in the heat of the financial crisis, Europe's banks are still trying to extricate themselves from the legacy of 2007-09, with regulators in Britain and the continent fearful that some of them are still too big to fail.
"If Barclays needs to raise that much capital, and it was relatively well capitalised by European standards, it suggests we've got a long way to go in Europe," said the head of equities at one UK fund manager.
"We'll see this creep in Europe, moving the bar higher and higher to get to where the regulators want to go, and we've still got a long way to go in terms of capital raising."
Barclays bore the brunt of a surprise new British curb on banks' risk exposure, requiring it to raise an extra 12.8 billion pounds of capital in the next year.
To meet the new target, Britain's third-largest bank by market value said it would tap shareholders for 5.8 billion pounds, shrink its loan book by 65-80 billion pounds and sell 2 billion pounds' worth of bonds, sending its shares sliding over 7 percent.
Tougher rules on risk discourage banks from lending, and Britain's business minister last week accused the country's central bank of holding back economic recovery by imposing higher capital levels on banks.
In the euro zone, national regulators are pushing banks to get their houses in order in anticipation of the European Central Bank taking over direct supervision of the bloc's largest banks next year.
Deutsche Bank, which has already raised around 5 billion euros in new debt and equity, said it had earmarked an additional 250 billion euros in assets, roughly equivalent to the annual economic output of Denmark, that could be cut to meet new bank safety rules.
Its shares were down 4 percent at 1245 GMT, underperforming the European banking index, which was down 0.4 percent.
In addition to pressure on capital, European investment banks are also in the cross-hairs of a number of regulatory probes including a global investigation into manipulation of benchmark interest rates and the mis-selling of mortgage-backed bonds in the United States.
In Frankfurt, Deutsche Bank set aside an extra 630 million euros to cover claims and settlements, causing it to miss quarterly profit expectations.
Even when banks settle with regulators, they still face further lawsuits from other aggrieved parties.
Barclays and Swiss bank UBS, which have already paid out nearly $2 billion over their role in the manipulation of benchmark interest rates, were named in a fresh lawsuit by the city of Philadelphia in connection with the scandal, along with Deutsche and a host of other banks.
Barclays also set aside another 2 billion pounds to cover compensation claims arising from mis-sold products in Britain.
UBS BRIGHT SPOT
In one of the few bright spots for European banking on Tuesday, UBS said it would buy back a fund set up to purge it of toxic assets during the financial crisis, drawing a line under its humiliating state bailout in 2008, boosting its capital and raising the prospect of an early increase in dividends.
UBS beat second quarter profit forecasts despite paying a $885 million fine to settle a lawsuit with the U.S. housing regulator over its role in the sale of mortgage-based securities.
UBS's second-quarter performance was driven by buoyant equity markets. Its decision to pull out of most areas of fixed income meant that unlike Deutsche Bank it was not hit by a drop in income from debt trading in the latter part of the second quarter after the U.S. Federal Reserve signalled an end to cheap money.
Leaving aside the litigation charge, Deutsche Bank's core investment bank underperformed U.S. rivals such as Goldman Sachs and Morgan Stanley. Revenues from Deutsche's investment bank rose just 9 percent, compared with double-digit jumps on Wall Street.
In Spain, Santander's core capital ratio, a measure of its capital strength, rose partly due to a reduction in lending, underlining the risk for regulators that the push for greater capital levels could further choke the supply of credit and hurt the wider economy.
Earnings from Santander's flagship Latin American businesses fell in the first half of the year as lending income from Brazil faltered, taking the shine off a turnaround in group profits.
Austria's Erste Bank has already met new global standards for capital and said it was more concerned that growth return to its core markets in central and eastern Europe.
"We belong to the best capitalised banks in Europe," Chief Executive Andreas Treichl told a news conference. "All we need is growth," he said.
