NEW YORK, Jan 7 (Reuters) - The euro struggled to stay above the key $1.30 level against the dollar on Friday as investors braced for upcoming bond sales from the more debt-stricken euro zone countries.
Meantime, global equities struggled to find direction as a softer-than-expected U.S. labor market report cooled some of the economic optimism that has fueled a rally since November. Copper prices eased on concerns about demand.
U.S. non-farm payrolls increased by 103,000 in December, the government said, falling short of a Reuters poll that forecast 175,000 new jobs last month. For details, see [
]However, the jobless rate fell to 9.4 percent, its lowest in more than 1-1/2 years, while payroll numbers in October and November were revised upward.
"You can't ignore the fact that, regardless of a disappointing payrolls outcome, U.S. growth is still looking better than Europe, and the euro sovereign stress is still there," said Richard Franulovich, senior currency strategist at Westpac in New York.

Earlier, investors sold bonds of the most indebted euro zone governments before a series of issues next week. An European Union proposal that could force those who lend to banks to bear big losses if they fail also helped knock the single currency lower across the board. [

Risk premiums on Portugal's 10-year government bonds over benchmark German Bunds <PT10YT=TWEB><DE10YT=TWEB> rose 15 basis points to 4.33 percentage points. while those on 10-year Spanish bonds <ES10YT=TWEB> over Bunds widened.

"The rising yields at debt auctions in the euro zone will continue to spook investors for a while, and it's best to stay away from peripheral stocks such as Spanish and Portuguese banks until mid-year, when the crisis should ease," said Arnaud Scarpaci, fund manager at Agilis Gestion in Paris.
