NEW YORK, Jan 6 (Reuters) - The euro fell against the dollar on Thursday and European government bond yields jumped as investor concerns re-emerged over the mounting bill for rescuing some euro zone countries and Europe's financial sector.
U.S. stocks mostly fell as some big U.S. retailers missed Wall Street estimates for December sales after a post-Christmas blizzard slowed a two-month shopping spree, driving down consumer shares. Energy shares declined along with oil prices.
Spreads between peripheral euro zone government bond yields and benchmark German debt widened as investors became spooked at the prospect of fresh supply next week from the region's higher-yielding issuers.
Wider spreads were driven by a rise in Portuguese debt yields as that country's IGCP debt agency said it will issue between 750 million euros and 1.25 billion euros in two bond maturities at an auction on Jan. 12. For details, see [
]Debt auctions in Spain and Italy are also scheduled for next week.
"It's continuing concern about the refinancing risk for euro zone countries in the next few weeks," said Samarjit Shankar, managing director of global foreign exchange strategy at BNY Mellon in Boston.
"In general, the euro is suffering from some fundamental concerns about the sustainability of the currency itself in terms of the sovereign debt crisis."
The euro fell to $1.2997 on trading platform EBS, its weakest level in five weeks. It last traded down down 1.2 percent at $1.3002 <EUR=EBS>.
The dollar index, which measures the greenback's value against a basket of major currencies <.DXY> was up 0.68 percent at 80.800.
The dollar's rise was bolstered by generally upbeat U.S. data and ahead of Friday's U.S. payrolls report, which is expected to show job gains of 175,000 in December, according to a Reuters poll. Some analysts are expecting employment gains of as much as 500,000.

The crisis in poorer euro zone states such as Greece and Ireland has triggered investor flight out of the so-called euro zone periphery, which also includes Portugal, Spain and Italy.
