NEW YORK, Sept 10 (Reuters) - The euro and dollar rallied against the yen while commodity bloc currencies rose on Friday, as strong import data from China raised optimism about global economic growth and prompted higher risk tolerance.
China's imports leapt in August, boding well for a strengthening of domestic demand in an economy that has become a major driver of global growth. [ID:nTOE689024].
News that Dubai World [DBWLD.UL] had reached a deal to restructure liabilities helped ease recently renewed fears about Dubai's debt woes and also boosted risk demand. [ID:nLDE6890IT].
The yen was down against the dollar but remained near the 15-year high touched earlier this week, keeping prospects for yen intervention alive.
The Swiss franc stumbled as investors sold safe-haven currencies.
"There has been strong risk assumption on the China data overnight," said John Doyle, senior currency strategist at Tempus Consulting in Washington. "The lack of U.S. economic data will also allow the dollar to trade in line with equities."
For the moment, currency markets shrugged off worries about
European banks and news of a possible 9 billion euro capital
raising by Deutsche Bank
The dollar rose nearly 1.2 percent on the day to 1.0271
francs
Traders cited Swiss banks selling the safe-haven franc against the euro, dollar and other currencies.
The euro was last little changed against the dollar at
$1.2694
Strategists have remained sceptical about any euro gains, given the euro zone periphery's debt worries and renewed concern this week about the region's banking sector.
"It is a risk-on environment which is helping the euro, but clearly structural problems remain given widening spreads and well known problems about its banking sector," said Simon Derrick, head of currency research at Bank of New York Mellon.
Derrick's bank's data showed demand was not recovering for assets in euro zone markets like Greece, Italy and Portugal.
European Central Bank executive board member Lorenzo Bini Smaghi warned on Friday of a looming debt crunch in several developed countries that could cripple economies if left unchecked. [ID:nLDE6890ZV]
YEN WATCH
Against the yen, the dollar traded in a tight range between
84.33 and 83.76
Japanese Prime Minister Naoto Kan reiterated that Japanese authorities would take decisive steps on the yen if needed. Joint intervention in currency markets, however, would be difficult, he said. [ID:nTOE689076]
The shift away from safe-haven currencies also kept the yen
under pressure against the higher-yielding currencies and the
euro
The euro was last up 0.7 percent at 107.16 yen.
The dollar hit a 15-year low of 83.34 yen on electronic

Investor attention is now turning to a ruling party leadership race on September 14 in which Kan faces a challenge from powerbroker Ichiro Ozawa.
