TOKYO, Jan 27 (Reuters) - The yen firmed broadly on Wednesday as investors remained jittery about risk-taking, with the focus still on China's efforts to curb lending and the outcome of a Federal Reserve policy meeting later.
But the Australian dollar climbed against the U.S. dollar after local data showed a rise in consumer prices, reinforcing views that the Reserve Bank of Australia will hike rates in February. [
] [ ]News of artillery fire between North and South Korea briefly weighed down the dollar and euro against the yen, a reaction traders said stemmed from a dip in South Korea's share market.
Talk that Japanese exporters sold dollars also helped send the greenback to a six-week low on the yen, while the euro, continuously pressured by fiscal concerns in the euro zone, hit a nine-month low against the Japanese currency.
The market has plenty to keep it jittery. The Fed ends a two-day meeting on Wednesday which is expected to yield little in terms of a policy shift but comes as the market waits to see if Chairman Ben Bernanke will be confirmed in his post for a second term. His current term expires on Sunday. [
]."Market sentiment is tilted toward further reluctance to take risks, with several factors at play including news related to China's tightening," said a trader at a Japanese bank.
The market is closely watching China's steps to rein in credit and prevent inflation and potential asset bubbles, with investors nervous the measures could also curb growth and demand for exports from other economies.
The Industrial and Commercial Bank of China, the country's largest bank, said on Wednesday it has stopped rolling over some loans to slow credit growth after a surge at the start of the year, though it will not halt new lending. [
]The dollar fell 0.4 percent to 89.25 yen <JPY=>. It had dropped as low as 89.14 yen on trading platform EBS, its weakest level since mid-December.
There was some talk of both bids and stop-loss offers at levels around 89.10 yen and 89.00 yen.
The euro shed 0.6 percent to 125.45 yen <EURJPY=R>, after falling as far as 125.30 yen, a fresh nine-month low.
President Barack Obama is also scheduled to deliver his State of the Union address, while a number of key U.S. companies are due to unveil earnings for the fourth quarter later on Wednesday. [

YEN AND DXY RISE
Both the dollar and the euro dipped below technical support against the yen. The dollar fell below 89.30 yen, a 50 percent retracement of its rise from the November 2009 14-year low of 84.82 yen up to its peak earlier this month of 93.78 yen.
The euro slipped below 125.67 yen, a 50 percent retracement of its rise from a trough hit in January 2009 up to a peak marked in June 2009. Market players said the next downside target could be levels near its April 2009 low of 124.38.
Traders said speculators were using this nervous environment to pare some long positions in higher-yielding currencies.
"We expect the FOMC to leave guidance that rates are likely to remain exceptionally low for an extended period unchanged," JP Morgan said in a note.
"Until then, markets will tread lightly, with risky markets likely biased lower until uncertainties are clarified."
Both the dollar and the yen, currencies used to fund investment in higher-yielding assets, have rallied in the past couple of weeks, while global equities <.MIAPJ0000PUS> including emerging market shares <.MSCIEF> have fallen.
The dollar index <.DXY> <=USD> edged up 0.1 percent to 78.507. The index, which measures the dollar's value against six major currencies, closed above its 200-day moving average on Tuesday for the first time since May 2009.
The euro <EUR=> dipped 0.1 percent to $1.4062 from late U.S. trading on Tuesday.
The Australian dollar climbed 0.2 percent to $0.9003 <AUD=D4> after the fourth-quarter consumer price index rose a little faster than forecast, almost guaranteeing a rate hike next week. (Additional reporting by Anirban Nag in Sydney, Masayuki Kitano in Tokyo; Editing by Joseph Radford)
