SYDNEY/TOKYO, March 28 (Reuters) - The euro dipped on Monday after German Chancellor Angela Merkel's conservatives lost a key state election and it could pull back towards $1.39 in the near-term, with the dollar supported after hawkish comments from some Fed officials.
Failure to break through option barriers around $1.4250 last week also saw some traders pare long exposure to the common currency, although support around $1.4015/35 appeared to be holding for now.
"It's being driven by the positioning in the market. Events in Portugal and German elections injected a little bit of uncertainty so the first reaction was to sell the euro," said Robert Reilly, co-head of flow fixed income and currencies at Societe Generale in Hong Kong.
The euro fell 0.3 percent from late U.S. trade on Friday to $1.4051, pulling further away from a 4-1/2 month high of $1.4249 hit last week on trading platform EBS.
Earlier on Monday, it was marked down to around $1.4020, after having triggered stops below $1.4050, with one U.S. bank cited as the main seller of the euro earlier in the day.
The euro has support at the 20-day moving average near $1.40, and trendline support around $1.3975, which is drawn through the euro's Jan. 10 low of $1.2860 and March 11 low of $1.3752.
A drop through such support could open the way for further falls, and traders said one-near term target may be $1.39.
The euro had been due for a pull-back, and the dollar due for a bounce, judging from market positioning.
The latest data from the U.S. Commodity Futures Trading Commission shows that currency speculators raised the value of dollar net short positions to $29.82 billion in the week ended March 22, up from $27.07 billion a week earlier.
DOLLAR HOLDS GAINS
Merkel's conservatives lost power in a regional stronghold on Sunday, with early poll results showing the Greens, buoyed by Japan's nuclear crisis, surging to their first premiership in the Baden-Wuerttemberg state. [
]This capped off a barrage of bad news for the euro last week including the collapse of the Portuguese government, the ensuing credit ratings downgrade and a delay by euro zone leaders to increase a rescue fund.
Still, the ECB seems to be on track for a rate hike next month with Governing Board member Ewald Nowotny on Sunday saying it wanted to move towards a more "normal" monetary policy despite recent events in Japan [

]Philadelphia Federal Reserve Bank President Charles Plosser, a well-known inflation hawk, said on Friday the U.S. central bank will have to reverse its easy money policy in the "not-too-distant future" to avoid sowing the seeds of inflation. [
]That gave markets a reason to buy the greenback and take profits on over-stretched positions in other currencies, although Fed fund futures continue to imply little chance of an actual tightening for the rest of the year <0#FF:>.
Plosser's comments were supported by St. Louis Federal Reserve President James Bullard, who said on Saturday that lengthening the "extended period" of low interest rates could encourage a liquidity trap. [
]The dollar index, which measures the dollar's value against a basket of currencies, edged up 0.1 percent to 76.324 , pulling well away from a 15-month low of 75.340 set on March 21.
Against the yen, the dollar rose 0.6 percent to about 81.78 yen , pulling away from a record low of 76.25 yen struck on March 17, when the yen jumped on stop-loss buying by retail margin traders and as option barriers were taken out.
That jump in the yen prompted joint yen-selling intervention by Group of Seven industrialised nations the very next day, and one factor limiting the dollar's downside against the yen now is wariness that Japanese authorities may intervene further if the dollar were to drop below 80.00 yen.
The higher-yielding Australian dollar was last at $1.0259 , not far from a 29-year peak of $1.0294 hit late last week. The yen-weakening intervention and stronger risk appetite were factors underpinning the Aussie's rise.
The Australian dollar was close to breaching resistance against the low-yielding yen. The Aussie rose 0.7 percent against the yen to 83.86 yen , nearing its 200-week moving average that lies at 84.14 yen.
