* Dollar nears 93.78 yen goal, yen sold broadly
* Euro holds near $1.3400, still vulnerable
* Aussie falls as data dampens rate hike bets

TOKYO, March 31 (Reuters) - The dollar hit a three-month high against the yen on Wednesday as the Japanese currency lost ground broadly, while the Australian dollar tripped after retail sales data dented expectations for an interest rate hike next week.
The euro held near $1.34 <EUR=>, remaining vulnerable above 10-month lows as a bout of short-covering appeared to have run its course, with euro zone fiscal worries never far away.
The dollar climbed above 93.50 yen <JPY=> to its highest since early January as short-term speculators unwound long yen positions ahead of the long weekend in London and New York, and sterling hit its highest in a month at 140.96 yen <GBPJPY=R>.
Traders said Japanese banks, life insurers and hedge funds were buying dollar/yen as the greenback broke above the key 93 yen level, cancelling out Japanese exporters' dollar selling.
Dollar buying for Japan's new fiscal year starting Thursday may have also helped push it higher, and the U.S. currency is likely to head towards this year's peak of 93.78 yen hit in January, they said.
"Dollar/yen may start the new quarter by falling once the squaring of positions is done," said an FX manager for a Japanese trust bank.
"But there is a risk that dollar/yen may keep its rising momentum if it manages to end today's New York trading above 93 yen, which would make charts look attractive for tech-driven players to chase the dollar higher."
The greenback has gained just 0.4 percent on the yen this quarter, following a climb of 3.7 percent in the prior quarter.
This year's high of 93.78 is now a target after the dollar broke above its 200-day moving average last week.
The dollar index <.DXY> edged up 0.1 percent to 81.564, holding below a 10-month high of 82.240 set last week. It has risen almost 5 percent this quarter as the euro has fallen, U.S. yields have gone up and data has supported the view the Federal Reserve will raise rates before the euro zone or Japan. <^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Insider daily forex comment http://link.reuters.com/nes85j ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^>
RATE HIKE QUESTION MARK
The Aussie dollar fell 0.4 percent to $0.9154 <AUD=> on the day after retail sales data came in lower than forecast, making players question whether the Reserve Bank of Australia would raise rates by 25 basis points to 4.25 percent next week as some expect. [
]Interbank futures edged up <0#YIB:> and the Australian dollar fell from a two-month high near 85.60 yen set early in the day before edging back up to 85.50 <AUDJPY=R> as the yen lost ground generally.
The Aussie has gained about 2 percent on the dollar and the yen so far this quarter, while the euro has lost about 6 percent in both cases.
The single European currency gained 0.5 percent on the day to 125.03 yen <EURJPY=R>, holding near a two-month high at 125.47 yen hit on Tuesday, with support expected at about 124.20.
But it slipped below $1.3400 <EUR=> as the dollar strengthened broadly.
Strategists say the signs of improvement in the U.S. economy and continuing fiscal problems in the euro zone are likely to keep the euro subdued in the near term against the greenback.
Greek plans to reopen a 20-year bond issue added to worries about its funding needs, while news that Ireland would take a bigger stake in the banking sector than planned added to the air of uncertainty. [

"The euro remains a sell on rallies."
The market is waiting for U.S. nonfarm payrolls data on Friday. Before that, however, the private sector ADP report for March is due at 1215 GMT on Wednesday, with 40,000 jobs forecast to have been created against a loss of 20,000 jobs in February. Also due at 1400 GMT are factory orders for February.
