LONDON, Jan 19 (Reuters) - The euro hit a four-month low against sterling and a one-month low against the yen on Tuesday on the back of a weak German sentiment survey and persistent concerns about Greek public finances.
German analyst and investor sentiment fell more than expected in January to its lowest level since July, with the ZEW economic sentiment index dropping to 47.2 in January from 50.4 in December, below forecasts for a fall to 49.5. [
]That pushed the single currency to its weakest in more than a week against the dollar.
The euro's biggest falls, though, were against sterling, which was boosted by a surge in UK inflation and as U.S.-based Kraft Foods Inc <KFT.N> agreed a recommended deal to buy Cadbury <CBRY.L> for around 11.9 billion pounds ($19.6 billion), creating the world's largest confectioner. [
]"The market has reacted to the ZEW data and the euro has moved lower, but we are still in a very technically driven market, with price action driven by day-to-day news," said Peter Wuyts, currency strategist at KBC in Brussels.
Worries about Greece were also "capping the topside" in euro/dollar, he said, as European Union ministers kept pressure on Athens to repair its public finances. [
]By 1220 GMT, the euro fell 0.6 percent against the dollar to $1.4290 <EUR=>, having fallen to $1.4282, its lowest since Jan. 8. It also fell against the yen to 129.80 yen <EURJPY=R>.
Against sterling, the single currency <EURGBP=D4> dropped to 87.30 pence, while the pound <GBP=D4> hit a six-week high against the dollar of $1.6459.
"The story is still one of a soft euro, but sterling is really taking the limelight at the moment," said Niels Christensen, FX strategist at Nordea in Copenhagen.
YEN RISES ON JAL, PARES GAINS
The yen gained against the dollar, hitting a 4-week high of 90.32 yen <JPY=>, according to Reuters data, after Japan Airlines <9205.T> filed for bankruptcy protection as expected, owing more than $25 billion. [
]Traders said the bankruptcy of JAL may lead to yen repatriation as the company may have to liquidate some of its dollar-buying derivative contracts or repatriate overseas assets, helping the currency. [
]But the euro's losses against the dollar and a lack of large follow-through yen buying helped push up the dollar to a session high of 90.89 yen, traders said.
Traders will look for cues from earnings results of Citigroup <C.N> and IBM <IBM.N> later on Tuesday. Bank of America <BAC.N> and Morgan Stanley <MS.N> are due on Wednesday.
The dollar index, a gauge of the greenback's performance against six major currencies, rose 0.5 percent to 77.505 <.DXY>.
The Australian dollar fell 0.7 percent to $0.9192 <AUD=D4> as China's central bank stepped up efforts to tighten liquidity by lifting auction yields on one-year bills for the second week in a row. [
] Any slowdown in Chinese growth is seen hurting Australian assets.The Canadian dollar fell 0.3 percent to C$1.0291 <CAD=D4> ahead of a Bank of Canada rate decision at 1400 GMT, when the central bank is expected to hold fire. [
]Investors will watch for the bank's tone on the strengthening Canadian dollar. Analysts say the possibility of central bank rhetoric may make the market wary of pushing the Canadian currency up significantly.
