TOKYO, Jan 28 (Reuters) - The yen fell and the dollar retreated from a six-month high against the euro after President Barack Obama laid out steps to revive the U.S. economy and eased market worries about moves to limit bank risk-taking by not revealing concrete plans on the issue.
Obama's announcement last week that he would seek sweeping reforms to curb risky lending by banks spooked financial markets, prompting investors to unwind leveraged yen-funded carry trades.
Before Obama's speech on Thursday the dollar powered to a five-month high against a basket of currencies, boosted by speculation over higher U.S. interest rates.
But the greenback trimmed gains versus the euro and fell against other riskier currencies after Obama pledged to double exports in five years to help create jobs, prompting some market players to think the U.S. government may seek a weaker dollar to promote exports. [

The euro was at $1.4010 <EUR=>, down 0.1 percent on the day but up from an earlier low of $1.3930 on trading platform EBS, its lowest since July.
The euro earlier fell sharply after hitting loss-cutting orders below $1.3980, traders said.
Worries about Greece's fiscal health continued to weigh on the euro, which has fallen from a high above $1.51 struck late last year.
The U.S. dollar index <.DXY> rose as far as 79.066, its highest since August. On a weekly chart it faced resistance from its 100-week moving average of 78.939.
ONE DOWN, ONE TO GO
On Wednesday the dollar got a boost from an optimistic tone by the Federal Reserve.
At the end of its two-day meeting, the Federal Open Market Committee kept rates unchanged, as expected, and said it intended to end some emergency lending and asset-buying programmes.
But what set the market aflutter was Kansas City Fed President Thomas Hoenig, who dissented on the decision to leave interest rates near zero because he wanted the Fed to remove a phrase vowing to keep them low for "an extended period".
That led to a sell-off in U.S. Treasuries, especially at the shorter end of the curve. [
]The dollar was also helped by news that the Fed and other major central banks said they would end emergency dollar lending operations on Feb. 1.[
].Fed Chairman Ben Bernanke's nomination for a second term faces a decisive day in the Senate later.
Bernanke had been widely seen as getting enough support but a public backlash at big banks and the way they were rescued from the financial crisis has meant the vote could be closer than expected and has also stirred up market uncertainty. [
]The dollar was up 0.3 percent at 90.24 yen <JPY=>, having risen 0.4 percent on Wednesday when it bounced from a six-week low of 89.14 yen on EBS.
The rebound was helped mainly by a rise in yields on U.S. Treasuries, which extended in Asian trade.
The euro rose 0.2 percent to 126.42 yen <EURJPY=R>, above a nine-month low of 125.23 on EBS struck the previous day.
The New Zealand dollar barely reacted to the central bank's decision to keep rates on hold. The move was expected and the Reserve Bank of New Zealand reaffirmed that it was looking at rate rises around the middle of the year.[
].But the kiwi later gained against the dollar and the yen together with other higher-yielding currencies, to climb 0.3 percent to $0.7087 <NZD=D4> and 0.7 percent to 63.90 yen <NZDJPY=R>.
Analysts said the rise in the higher yielders was partly a relief rally after they were sold off in the past two weeks on concerns about tightening in China.
The Australian dollar rose 0.9 percent to 81.17 yen <AUDJPY=R>, meeting resistance at its 100-day moving average at 81.60 yen, and 0.6 percent to $0.9004 <AUD=D4>. (Additional reporting by Kaori Kaneko and Charlotte Cooper; Editing by Michael Watson)
