TOKYO, Jan 29 (Reuters) - The euro hit a nine-month low on the yen and a six-month low on the dollar on Friday as concerns about Greece's fiscal situation intensified, while the Japanese currency rose broadly as weaker stocks further clouded sentiment.
After a week of worries over debt of smaller euro zone countries, White House plans to limit risk-taking at U.S. banks, credit tightening steps in China and a slide in global stock markets, investors have cut risk trades funded by the yen and dollar.
Traders said there was talk of loss-cutting sell orders on the euro below $1.3890-80 <EUR=>, just below the day's trough at $1.3912, but that its dip to a fresh low in early Asian action had cleared out many sell orders against the yen for now.
"It's getting harder to see how much further the euro will fall against the dollar and the yen," said Hideki Hayashi, global economist at Mizuho Securities.
"Worries about tighter monetary policy in China are likely to keep Asian stocks shaky next week, so risk aversion moves are expected to remain in place," Hayashi said.
A batch of data is due in the euro zone, including inflation and unemployment, but the main data focus will be U.S. fourth-quarter gross domestic product at 1330 GMT.
The U.S. economy is expected to have grown at an annualised 4.6 percent in the fourth quarter, double the rate in the third quarter when the economy resumed expansion after four consecutive quarters of decline.
The dollar index <=USD><.DXY>, a measure of its performance against six other major currencies, touched a five-month high at 79.156. It reached above its 100-week moving average of 78.94, and a weekly close above there will be a bullish signal.
The euro fell 0.3 percent from late U.S. trade to $1.3932 <EUR=>, recovering slightly from an early drop to $1.3912 on trading platform EBS, its weakest point since mid-July, as investors worried Greece may not be able to service its debt.
It is on track for a loss of about 2.5 percent this month although not as steep as December, when it fell 4.5 percent.
It also tumbled against the Swiss franc, dropping to 1.4645 francs <EURCHF=R>, its lowest since last March, the month the Swiss National Bank intervened to counter franc strength.
Traders said there was talk of a barrier targeted down at 1.4650 francs, but the market is wary of the possibility of franc selling by the Swiss central bank and it recovered to 1.4668 francs later. The central bank was reported as saying last week it would prevent any excessive rise in the franc. [
]GREEK FOCUS
Germany and France denied a report suggesting an imminent European Union bailout for Greece, while Athens said it had not requested help and was the victim of speculators intent on attacking it as the euro zone's "weak link". [
]"Some who are very bearish about the euro have even started to worry that the single currency system might be falling apart," said a senior currency trader at a Japanese brokerage.
The premium that investors demand to hold Greek government bonds rather than benchmark German Bunds rose to its highest since the euro was launched more than a decade ago and the cost of insuring Greece's sovereign debt against default also hit a record high. [
]The euro fell 0.3 percent to 125.26 yen <EURJPY=R>, pulling back up from a nine-month low of 124.81 yen hit on EBS.
The next chart focus is its April trough of 124.38 yen, traders say, although its 14-day relative strength index has dropped to 26, signalling selling on the pair is now quite stretched. A reading of 30 or below signals a pair is oversold and above 70 that it is overbought.
The dollar also slipped initially but later recovered to stand flat on the day at 89.92 yen <JPY=>, above a six-week low set on Wednesday at 89.14 yen.
A fall on Wall Street also undermined investors' willingness to hold risk positions, with many share markets in Asia also down more than 1 percent. [
]The yen's gains were trimmed as dollar buying emerged related to Japanese investment trusts, known as toushin, a currency trader at a Japanese brokerage said.
The higher-yielding Australian and New Zealand dollars both slipped in early trade against the low-yielding U.S. dollar and the yen.
One trader reported Australian dollar selling by Japanese players as well as leveraged funds. The Aussie fell to its lowest in six weeks below 79.70 yen <AUDJPY=R> before recovering some ground to 80.20 yen.
Both the Australian and New Zealand dollars briefly hit their lowest in a month against the dollar.
