* Dollar index dips but still close to recent highs
* Greek yield spread widens on continued fiscal worries
(Updates prices, adds fresh comment)

LONDON, Dec 21 (Reuters) - European shares rose on Monday, led by banks, while the euro stayed weak against the dollar on worries over Greek debt and expectations the U.S. economy may recover more quickly than the euro zone.
The rise in shares -- an index of leading European stocks was up 0.6 percent -- helped push safe-haven euro zone government bonds lower. Gold steadied after hitting multi-week lows last week, but gains were capped by the firm dollar, and crude oil prices rose.
Banks were the top gainers among European shares, recovering from concerns over tougher capital regulation. The banks rebounded after losses last week following proposed new rules from the Basel Committee on banking supervision.
"Sovereign risks and banks have been the main worry that the markets have been adjusting, but I think that's well priced in now," said Bernard McAlinden, investment strategist at NCB Stockbrokers in Dublin.
Heavyweight oil producers rose as crude prices stayed firm after a 1 percent rise on Friday.
London Stock Exchange rose after it agreed to take a 60 percent stake in rival trading platform Turquoise and merge it with its own "dark pool" platform Baikal.
Japan's Nikkei average rose 0.4 percent to an eight-week closing high on gains in high-tech exporters such as chip-tester Advantest Corp and boosted by a weaker yen.
U.S. stock index futures rose, pointing to a firm start on Wall Street. Futures for the Dow Jones average, S&P 500 and Nasdaq Composite were up 0.2-0.4 percent. The euro stayed weak against the dollar on persistent concerns over the fiscal health of Greece. The dollar was also supported by the brighter outlook for the U.S. economy after stronger job market and retail sales figures last week.
The euro was all but flat on the day at $1.4359, after falling to its lowest since September on Friday. The dollar index, which measures the greenback's performance against a basket of six currencies, was down 0.13 percent but still close to its highest for almost three months.
"It looks like we may be seeing better growth prospects in the U.S. than the euro zone. Better employment and retail sales data in the U.S. has raised the possibility of a cyclical recovery in 2010," ING currency strategist Chris Turner said.
GREECE WEIGHS
Euro zone government bonds fell as shares rose but trade was thin ahead of the holiday season. Worries about Greece hit its government bonds in recent weeks. Standard and Poor's and Fitch have already cut their credit ratings on Greece.
March Bund futures were down 28 ticks at 123.38 and benchmark German 10-year bonds were yielding 3.16 percent, up 2 basis points. The premium investors demand to hold Greek debt rather than German rose around 18 basis points to 281.
"The periphery is probably going to remain the focus but trading has been thin anyway the last few sessions and that is unlikely to change," a trader said.
Oil held firm above $73 a barrel, after a 1 percent rise on Friday, as Iranian troops partly withdrew from a disputed oil area claimed by Tehran and Baghdad, easing tensions between two major crude exporters.
Crude for January delivery rose 16 cents to $73.52 a barrel. London Brent crude was up 73 cents at $74.48.
Gold prices steadied but gains were capped by recent dollar strength. Spot gold was at $1,113.50 an ounce, compared with $1,112.25 in New York late on Friday. (Additional reporting by Charlotte Cooper, Dominic Lau, Jessica Mortimer and Kirsten Donovan; Editing by Toby Chopra)
