LONDON, Sept 6 (Reuters) - The dollar dipped on Monday and looked set to test a 15-year low against the yen after shedding gains made after U.S. jobs data, while greater appetite for risk prodded the euro to a three-week high versus the U.S. currency.
U.S. payrolls data last week, which showed far fewer jobs lost than expected, eased market anxiety over the chances of a global slowdown and boosted demand for growth-linked currencies such as the Australian dollar. Equity markets also rose.
"Risk sentiment is a little bit better, building on gains from Friday," said Adam Cole, global head of FX strategy at RBC Capital Markets.
The euro rose to $1.2918, its highest since Aug. 12, helped by Asian central banks, excluding Japan, converting dollars into euros after they intervened to rein in gains in their own currencies against the greenback, traders said.
Trade was subdued with U.S. markets closed for the Labor Day holiday. By 1110 GMT, the euro was slightly lower at $1.2876, as intraday players closed long positions after gains were capped by offers from semi-official names around $1.2920, traders said. Stops were seen through $1.2865, they said.
U.S. non-farm payrolls fell 54,000, a much smaller drop than the predicted 100,000. Private employment, considered a better gauge of labour market health, increased 67,000. [
]The dollar index <.DXY> was flat from late Friday U.S. trade at 82.10. Support was seen at 81.82 -- the 50 percent Fibonacci retracement of the index's rise from 80.085 to a high of 83.559, in August.
YEN LONG POSITIONS TRIMMED
The dollar also ceded ground against the yen, dropping 0.1 percent to 84.22 yen <JPY=>, not far from a 15-year low of 83.58 hit last week. It had risen to 85.23 after the U.S. jobs data, but quickly erased the gains.
The pair has been highly correlated with U.S. bond yields. In the past month, the yield on the benchmark 10-year U.S. Treasury note <US10YT=RR> has shed 12 basis points, while dollar/yen has fallen more than 1.5 percent in the period.
On Friday, the dollar did not make much headway versus the yen even as payrolls pushed U.S. yields sharply higher, with a spike in Japanese bond yields partly offsetting the rise.
Japanese exporter offers also capped gains in the dollar, with sell orders in the 84.50-85.00 yen region, traders said.
Speculators trimmed their long positions on the yen last week but still have big yen long positions, data from the U.S. Commodity Futures Trading Commission showed on Friday. [
]Hedge funds were selling dollar/yen while other asset managers were emerging as bit buyers, said Gareth Berry, currency strategist at UBS.
On Saturday, Japanese Finance Minister Yoshihiko Noda said Tokyo would take decisive steps to stem the yen's rise when needed while suggesting coordinated currency intervention in the market was a difficult option. [

"For intervention to work, it has to be coordinated and it does not look that the U.S. is prepared for that," said Bilal Hafeez, foreign exchange strategist at Deutsche Bank.
"So going solo by the Japanese authorities could work for a day, but unlikely beyond that. We are looking for the dollar/yen to fall to 80 yen in the medium term."
