TOKYO, March 18 (Reuters) - The euro tumbled broadly on Thursday after a newswire report saying that Greece is not hopeful of receiving aid from other euro zone members.
A Greek official quoted in the report said the country was growing increasingly pessimistic about the prospect of help at a European Union summit on March 25 and may seek IMF aid during during the April 2-4 Easter weekend.
Greece has said it was counting on EU leaders to approve an aid mechanism for the country at the meeting next week as it battles to deal with crippling debts.
But some countries -- especially Germany, the EU's biggest paymaster -- are wary of making any concrete promises, and market participants said the Dow Jones Newsires report suggested a rift between Greece and Germany may be deepening. [
]"Euro selling was sparked after the report. It forced many investors to dump euro long positions after the recent relative calm on the Greek debt woes helped some to buy the euro back," said a senior trader for a Japanese securities firm.
The euro dropped as far as $1.3667 on trading platform EBS before stabilising at $1.3678 <EUR=>, down 0.4 percent. It pulled back further from a five-week high of $1.3819 on EBS the previous day.
The euro had been struggling as other euro zone nations have yet to give specific details on how they will help Greece resolve its financial woes. [
]Traders said stop-loss orders around $1.3700 and $1.3680 were hit, making the euro's fall sharper.
The euro was under broad selling pressure. It fell 0.2 percent against sterling to 89.44 pence <EURGBP=> and slid 0.1 percent versus the Swiss franc to 1.4460 franc <EURCHF=>, a fresh 17-month low.
The dollar rose broadly and recovered some losses made the previous day against higher-yielding currencies such as the Aussie, as investors covered short dollar positions.
The greenback had fallen on Wednesday after a benign inflation reading supported the Federal Reserve's renewed pledge to keep interest rates near zero for a few more months.
Short-term players trimmed their stretched dollar short positions against the Canadian dollar which hit a 20-month high the previous day, helped by higher oil prices.
The Australian dollar fell further from an eight-week peak the day before as demand for riskier assets decreased after reported Greek comments.
The Australian dollar fell 0.3 percent to $0.9213 <AUD=D4>, off an eight-week high of $0.9253 hit the previous day.
Against the Canadian dollar, the greenback rose 0.3 percent to C$1.0129 <CAD=D4>, rebounding above the C$1.0071 hit on Wednesday, its lowest since July 2008.
The dollar index, a gauge of the greenback's performance against six major currencies, rose 0.4 percent to 79.993, rebounding from a six-week low of 79.507 struck on Wednesday <.DXY>.
The dollar dropped 0.2 percent to 90.14 yen, remaining below a three-week high of 91.09 yen hit last week with traders citing persistent dollar offers around Wednesday's high of 90.72 yen.
The dollar's fall against the yen stemmed from the yen's rise against the euro which fell 0.5 percent to 123.35 yen <EURJPY=R>. (Editing by Joseph Radford)
