* Asia stocks edge up, Seoul hits 6-wk high
* Dollar and yen dip as risk-taking improves before year-end
* Higher-yielding currencies and oil gain

HONG KONG, Dec 22 (Reuters) - Asia stock markets edged up on Monday and the dollar retreated after the U.S. government's $17.4 billion of rescue loans to ailing automakers last week gave investors more reason to wade into riskier assets.
Higher-yielding currencies such as the Australian dollar gained against the yen after the Bank of Japan last week followed the U.S. Federal Reserve in cutting interest rates to nearly zero and vowing to buy troubled assets and help thaw credit markets.

Japanese government bonds extended gains after the BOJ upped the amount of debt it would purchase each month as part of its monetary easing measures, even as U.S. Treasuries retreated on the gains in Asian stocks and U.S. stock futures.
The MSCI index of Asia-Pacific stocks outside Japan <.MIAPJ0000PUS> edged up 0.2 percent, before paring gains. But for the year, the index is still down 52 percent.
Portfolio managers have kept shifting funds into Asian equity markets in a sign of more tolerance for risk. Data from EPFR Global showed Asia ex-Japan funds received a fifth straight week of inflows in the week ending last Wednesday.
DOLLAR DOWN
The dollar and yen dipped against the euro as currencies offering higher-yields benefited from the gradual reemergence of risk-taking as a brutal 2008 draws to a close.
The dollar bounced back on Friday after sliding to a 13-year low against the yen and a three-month low against the euro last week, with investors expecting European policymakers to be more reluctant to cut rates from 2.5 percent.
Market players also covered some of their hefty bets against the euro going into the end of the year, helping drive the single European currency up nearly 8 percent against the dollar in just three trading days last week.
Analysts said the dollar's woes were starting to reflect the bleaker outlook for the world's biggest economy.
"The picture that the currency market is painting for the U.S. economy next year is not as hopeful as the one in the stabilising stock markets," said Kengo Suzuki, a currency strategist at Shinko Securities.
The Australian dollar dipped slightly against the U.S. dollar to $0.6805 <AUD=D4>, but rose 0.7 percent to 61.25 yen <AUDJPY=R>.
The Aussie was also underpinned by rising commodity prices.
U.S. crude oil for February delivery <CLG9> was up 81 cents at $43.17 a barrel <CLc1>, well above the slide in the January contract to below $33 last week.
Safe-haven government bonds were mixed.
March JGB futures <2JGBv1> climbed 0.25 point to 139.93 and hit a three-month high of 140.14, while the benchmark 10-year yield <JP10YTN=JBTC> dipped 1 basis point to 1.215 percent and was near a 3-1/2-year low hit on Friday.
But Treasuries slipped. Ten-year notes <US10YT=RR> were down 3/32 in price to yield 2.137 percent, up 1 basis point from late U.S. trade Friday and off the five-decade low of 2.040 percent touched last week.
Long-term Treasury yields plunged after the Fed reiterated that it was considering buying such bonds as part of its efforts to revive bank lending and credit markets to help the economy. (Additional reporting by Kim Yeon-hee in SEOUL and Satomi Noguchi in TOKYO; Editing by Dhara Ranasinghe)
