SINGAPORE, April 15 (Reuters) - The euro dipped but stayed within sight of a 15-month peak against the dollar on Friday, with further losses expected to be limited given the diverging outlook for monetary policy in the euro zone and the United States.
Not helping the dollar, several top Federal Reserve officials have sounded relaxed about inflation despite the recent surge in oil prices, adding to expectations the Fed will not cut short its $600 billion debt-buying programme. [
]The euro, in contrast, remains supported by the prospect of higher interest rates in the euro zone despite comments by Germany that Greece may need to restructure its debt [
]."When you are talking about the relative yield play, it probably does favour the euro," said Andrew Robinson, FX analyst for Saxo Capital Markets in Singapore.
"I don't think there is much in the way to prevent further dollar slippage," Robinson said, adding that a meeting of Group of 20 finance officials on Friday seemed unlikely to cause a shift in that trend.
The euro eased 0.1 percent from late U.S. trade on Thursday to $1.4472 , still not very far from a 15-month high of $1.4521 hit earlier this week.
An option barrier in the euro lies at $1.4525 and there are stops above that level, going up to $1.4550, said a trader for a European bank in Singapore.
The existence of such an option barrier suggests the euro could face selling from options players if it rises close to the barrier level, but also means the euro could find it easier to rise if the barrier is taken out or it expires.
Market players said the euro could find the going tough above $1.45 given the sovereign debt problems, which took a turn for the worse after Germany suggested for the first time that Athens may have to restructure its large debt load.
Greek borrowing costs soared to new highs on Thursday and added pressure on other financially weak euro zone members.[
]The euro fell 0.2 percent against the yen to 120.76 yen , but remained well above a low of 119.26 yen hit the previous day. The trader for a European bank in Singapore cited selling of the euro against the yen by model funds.
The single currency has given up some ground against the yen since hitting an 11-month peak of 123.33 yen on trading platform EBS earlier this week.
There was little impact on currencies from a batch of Chinese data released on Friday, with most of the numbers already having been reported by Hong Kong media the day before.
Friday's data also showed China's economic growth eased just a touch to 9.7 percent in the first quarter from a year earlier, down from 9.8 percent in the last quarter of 2010 but ahead of an expected 9.5 percent increase. [

The dollar edged up 0.1 percent against a basket of major currencies to 74.770 , near a 16-month trough of 74.617 struck on Thursday.
"The long-term story of recycling reserves out of dollars remains ever more pronounced following China's record reserve accumulation in Q1 of over $3 trillion," analysts at BNP Paribas wrote in a client note.
Indeed, following Singapore central bank's decision on Thursday to allow its currency to strengthen to tackle inflation, the long-Asian-currencies story remains intact, they said.
"The flows into Asia will therefore continue - and the recycling of intervention USD will too, especially since we do not expect much FX appreciation pressure on Asian monetary authorities at the G20/IMF meetings this weekend," said BNP.
U.S. economic data on Thursday also failed to excite dollar bulls and a surprise jump in U.S. jobless claims raised questions about the health of the labour market recovery. [
]The dollar held steady at 83.46 yen .
Like the dollar, the Japanese currency has been used as a funding currency because of the Bank of Japan's ultra-loose monetary policy. The BOJ may ease further to support a recovery after last month's devastating earthquake and tsunami.
Another focal point for the yen is whether Japanese institutional investors will step up investment in overseas assets in Japan's new fiscal year that started this month.
Japan's Fukoku Mutual Life Insurance said earlier this week it plans to increase its foreign bond holdings by about $826 million while reducing its currency hedging for overseas debt on a bet the yen will weaken during the financial year to March 2012. [
