TOKYO, June 9 (Reuters) - The euro lost steam on Wednesday, keeping near a four-year low on the dollar, although talk of sturdy support at $1.1900 stopped it sliding too far, while higher-risk currencies slid as Asian share markets fell.
The euro also remained near an all-time trough against the Swiss franc, set on Tuesday below 1.38 francs <EURCHF=R> when the Swiss National Bank declined comment on whether it intervened to weaken the franc. [
]Traders and analysts said the focus was on the European Central Bank and what it could do to shore up sentiment, and with the market awaiting the next trigger, the euro was caught between strong bids linked to options around $1.1900 and heavy offers expected above $1.20.
ECB chief Jean-Claude Trichet speaks later in the day ahead of an ECB meeting on Thursday that the market will watch for more signals or steps to ease strains from the euro zone's debt crisis or support the economy. [
]German 10-year bond yields fell to a record low on Tuesday as investors sought the safety of the euro zone benchmark paper on continued worries about fiscal woes in euro zone countries and Britain, after a warning to the UK from ratings agency Fitch.
"Despite the substantial (euro zone) policy package and the details we have got on that, European bond markets continue to show signs of stress and that suggests the euro can fall further from here," said John Horner, FX strategist at Deutsche Bank in Sydney.
The euro slipped to $1.1940 <EUR=>, down 0.3 percent from New York trading levels but above Monday's four-year low of $1.1876.
Chart focuses for the market are expected options triggers around $1.1850 and a low set in early 2006 at about $1.1825. Horner said Deutsche Bank expected the euro to slide to $1.15 over the coming few months.
Analysts say liquidity is below levels seen earlier in the year, making price action volatile, with rebounds catching out short-term players by their triggering stop-losses, even though the overall downward trend for the euro remains clear.
"There are some who believe that the ECB may go as far as to lower interest rates, although this view is not widely held," said a trader for a Japanese trust bank.
"But if the ECB only offers to supply more funds and does not meet market expectations for bold steps to help the economy, the stock market may not react positively and that could hurt the euro too," he said.
YEN TAKES BACK GROUND
The euro slipped 0.3 percent from late U.S. levels to 109.17 yen <EURJPY=R> after gaining 0.5 percent on Tuesday. One broker said selling by Japanese insurers briefly helped push it below 109.00 yen early on.
The Australian dollar, which bounced more than 2 percent against the yen in the previous session, fell 1 percent to 74.96 yen <AUDJPY=R>, its losses deepening as Asian share markets headed lower. The New Zealand dollar <NZDJPY=R> also shed 1 percent.
Japan's new prime minister, Naoto Kan, formed his cabinet on Tuesday. His new finance minister, Yoshihiko Noda, declined to comment on foreign exchange levels, saying just that excessive moves hurt the economy and financial markets.
"In terms of FX implications, the market expected too much for a weak yen policy by Kan," said Masafumi Yamamoto, chief FX strategist at Barclays Capital in Tokyo.
The dollar held steady on the day at 91.45 yen <JPY=>.
The Aussie also lost ground to the U.S. dollar after climbing more than 2 percent on Tuesday. It slipped 0.5 percent to $0.8215 <AUD=D4>, pressuring chart support at $0.8210/20.
The U.S. dollar index <.DXY>, a measure of its performance against six other major currencies, slid 0.1 percent to 88.316, below a 15-month peak of 88.708 on Monday.
Sterling eased 0.2 percent to $1.4425 <GBP=D4> but held steady against the euro at 82.77 pence <EURGBP=D4> after falling on Tuesday when Fitch said fiscal challenges facing Britain were "formidable".
