LONDON, March 28 (Reuters) - The euro eased on Monday, heading into a cluster of Asian demand and technical support, after Germany's ruling party lost a key state election, while hawkish comments by Federal Reserve officials lifted the dollar.
The loss by Chancellor Angela Merkel's conservatives of Baden-Wuertemberg, which they had held for nearly six decades, led markets to bet Merkel will have less leeway to shore up financially stricken members of the single currency bloc.
The higher-yielding Australian dollar <AUD=D4>, hit a 29-year peak of $1.0315, breaking past option barriers at $1.03. Recent intervention to weaken the yen and stronger risk appetite were factors underpinning the Aussie's rise, traders said.
For the euro, the failure to break through option barriers near $1.4250 last week saw some paring of speculative long positions, moving it towards reported Asian central bank bids at $1.4030/10.
"It is a combination of setbacks to German Chancellor Angela Merkel's party and the dollar being lifted by those comments from Fed officials which led some investors to short the euro," said Adam Myers, senior currency strategist at Credit Agricole.
The euro <EUR=> was down 0.2 percent to $1.4044, off a 4-1/2 month high of $1.4249 hit last week on EBS. It fell to around $1.4020 in the Asian session.
Near-term support lies 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.
"Events provide downside risks (for the euro) in our opinion," said fx analysts at Barclays Capital in a note.
"These include discussion over bank funding and recapitalisation in Ireland ahead of the bank stress-test results (published on 31 March), concerns about Portugal, and about the impact of potentially waning political support in Germany for its financial contribution to the euro rescue package," said fx analysts at Barclays in a note.
The euro had been due for a pull-back, and the dollar for a bounce, judging from market positioning. Latest data from the Commodity Futures Trading Commission shows speculators raised the value of dollar net short positions to $29.82 billion in the week ended March 22, up from $27.07 billion. [

DOLLAR MOVING UP
Sunday's election loss to the Greens, who surged to their first premiership in Baden-Wuerttemberg, was the second defeat for Merkel's Christian Democrats in states usually regarded as strongholds for the party. [
]The defeat was blamed on Merkel's reversal of nuclear policy following Japan's nuclear crisis and foreign policy issues, but could cast doubt on whether Merkel's policy on Europe has the support of the German people.
Losses in the currency are likely to be limited, however, with the European Central Bank still expected to raise rates next month. ECB President Jean-Claude Trichet speaks at 1300 GMT and is likely to reiterate his hawkish stance towards inflation.
The dollar meanwhile held on to Friday's gains sparked by hawkish comments from regional Fed officials Charles Plosser and James Bullard. [
][ ]"Comments from Bullard, who is a cheerleader for quantitative easing, shows a sea-change as to whether the endgame for QE2 is approaching," said Jeremy Stretch, head of currency strategy at CIBC.
"If we get reasonably supportive ISM manufacturing data and U.S. payrolls this week, we could see the dollar index testing its 50-day moving average."
The dollar index edged up 0.2 percent to 76.348 <.DXY>, pulling away from a 15-month low of 75.340 set on March 21. Its 50-day moving average comes in at 77.285 on Monday.
The dollar was up 0.5 percent at 81.70 yen with implied volatilities staying low, which traders said was ruling out the need for any further official yen selling intervention in the near-term.
One-month dollar/yen vol traded around 10 percent <JPY1MO=>, compared to around 20 percent when the yen rose to a record high of 76.25 earlier this month.
