TOKYO, May 6 (Reuters) - The yen climbed steeply on Wednesday, jumping more than 1 percent versus the Aussie and euro, after a source said Bank of America <BAC.N> was deemed to need more capital, prompting investors to lighten riskier positions.
The market was already pocketing profits from bets this week against the yen and the dollar when a source familiar with the U.S. bank stress test results said Bank of America was believed to need an additional $34 billion in capital. [
]The news deepened losses in the euro, Australian and New Zealand dollars and also prompted the dollar to fall against the yen, which has been used to fund positions in commodity-related currencies in recent weeks when investor confidence had picked up.
"It's really caught the market in a mood of cautiousness and that's exacerbated the pullback in some of the riskier currencies," said Mitul Kotecha, global head of FX strategy at Calyon in Hong Kong.
Although Bank of America has been at the top of the list of banks believed to need more capital in the stress test results expected to be published late on Thursday, the $34 billion is higher than published reports had speculated the largest bank might need.
Stocks fell on the news with S&P futures <SPc1> falling 1 percent, pointing to a weak Wall Street. [
]"It definitely is more. That's what's hit now -- it's the sheer size of the additional capital that's being speculated on," Kotecha said.
The euro <EUR=> fell 0.5 percent on the day to $1.3261 <EUR=> after touching its highest in a month at $1.3439 on trading platform EBS on Tuesday.
A trader at a European bank said if it fell through $1.3200-1.3180 it could see more stop-loss sales.
It shed 1.3 percent to 130.14 yen <EURJPY=R>, well below a three-week high of 132.87 yen set on Monday.
IN NEED OF A CORRECTION
Traders said the market had been overextended in its long positions on currencies such as the euro and Australian dollars, hence the extent of the pullback. Profit-taking was broad-based, with hedge funds reducing positions.
Trading was also a little thin with Japan shut until Thursday for Golden Week holidays.
The dollar fell 0.7 percent to 98.13 yen <JPY=> although its index on a basket of six currencies <.DXY> strengthened 0.2 percent to 84.307, up from a five-week low on Tuesday.
"Overall looking at the euro and the dollar index we're in a reasonable-sized range so in the medium term this is just a correction rather than a big long-term move," the trader said.
Commodity-linked currencies such as the Australian <AUD=D4> and New Zealand dollars <NZD=D4> have benefited as investor confidence has grown that the worst of the global recession may be over.
The Aussie hit seven-month highs this week and both currencies were already under profit-taking pressure before the Bank of America news, which also overshadowed data showing a surge in Australian retail sales in March. [
].The Aussie shed 0.7 percent on the day to $0.7361 and 1.4 percent to 72.32 yen <AUDJPY=R>. The kiwi fell 1 percent against the yen and half a percent on the dollar.

The market is also wary ahead of Thursday's policy announcements by the European Central Bank (ECB) and Bank of England (BoE).
The ECB is expected to cut its main interest rate to a record low of 1 percent, while the BoE is seen holding rates at 0.5 percent, also a record low.
But, more importantly, markets want to see if the ECB suggests it will keep cutting rates or adopt quantitative easing measures, following the Fed's footsteps, to stimulate growth. (Additional reporting by Anirban Nag in Sydney; Editing by Neil Fullick)
