* Yen takes a breather as uncertainty over Bernanke recedes
* Demand for high-yielders and euro still shaky
* Investors remain cautious about Obama's bank plan

TOKYO, Jan 25 (Reuters) - The yen and the dollar dipped on Monday while the euro and high-yielding currencies advanced, lifted by reports that Ben Bernanke was moving closer to being confirmed for a second term as chairman of the Federal Reserve.
Resilience in Chinese shares <
> and U.S. stock futures <DJc1> <SPc1>, after a 2 percent fall on Wall Street on Friday, also encouraged investors to buy back some currencies, such as the Australian dollar, which were sold off heavily last week.Markets have been fretting since late last week over whether Bernanke would be approved for the job. [
]Several key senators had announced their opposition to Bernanke's reappointment, spooking investors already unnerved by President Barack Obama's plans to limit risk-taking by banks. But the Fed chief edged closer to winning support after the Senate's Republican leader predicted he would be confirmed. [
].Still, demand for riskier assets and higher-yielding currencies is likely to remain subdued amid rising concerns over Greece's fiscal problems, worries that China's efforts to curb its surging economy may impair global growth and fears that White House plan could impact U.S. bank earnings.
"The timing (of Obama's plan) is extremely bad. It could ruin gains in share prices further, which was a core reason why the smooth global recovery was possible," said Kosuke Hanao, head of treasury product sale at HSBC in Tokyo.
"Falls in share prices, if they are extended, could dampen consumer spending and employment. The negative impact would not stop at Wall Street but could spread into the economy as a whole," Hanao said.
The dollar rose 0.3 percent to 90.06 yen <JPY=> after falling as low as 89.71 yen on trading platform EBS in early Asian trade, its lowest since late December.
The euro climbed 0.4 percent to 127.57 yen <EURJPY=R>, off a nine-month low of 126.55 yen hit on EBS last Friday.
The Australian dollar was trading at 81.60 yen <AUDJPY=R>, right on its 100-day moving average, after hitting 80.75 on Friday, its weakest in nearly a month.
Data showed that Japanese margin traders nearly doubled their overall net long positions in dollar/yen and six major cross/yen pairs on Friday, taking advantage of the gaining yen.
A big part of those increases in net long positions came after investors shed gross short positions in Aussie/yen and dollar/yen.
The retail traders also slightly increased their record net long positions in euro/yen on Friday, despite the euro's slide.

The dollar index <.DXY> <=USD> was down 0.1 percent at 78.18, below a 4-1/2-month high of 78.814 touched last week.
The euro rose 0.2 percent to $1.4165 <EUR=>, although traders said the single currency was unlikely to run much higher with its 200-day moving average at $1.4315 expected to provide resistance.
Among higher-yielding currencies, the Australian dollar advanced 0.8 percent to $0.9069 <AUD=D4> and the New Zealand dollar also climbed 0.9 percent to $0.7163 <NZD=D4>.
Still, the U.S. dollar could get a boost from some important events lined up this week, analysts said.
The Federal Reserve's first interest rate meeting of the year will be held on Tuesday and Wednesday.
The Fed is widely expected to keep rates on hold near zero, although it may sound more optimistic about an economic recovery.
Fourth-quarter U.S. gross domestic product numbers are due on Friday and a Reuters poll of economists suggests the economy grew at 4.5 percent, its fastest pace of growth in nearly four years. [
