* Upbeat ADP jobs data support view on earlier Fed tapering

NEW YORK, Dec 4 (Reuters) - U.S. Treasuries prices slumped

on Wednesday as robust data on private-sector jobs and new home

sales supported expectations that the Federal Reserve would be

encouraged to pare its stimulative bond purchases sooner than

expected.

The price decline pushed benchmark yields to their highest

level since mid-September. Short- and medium-dated yields

climbed to their highest levels in about three weeks.

The market stabilized after the Institute for Supply

Management's gauge of U.S. services industries fell more than

expected in November, suggesting slower growth in that sector

and reviving some bids for government bonds.

"The market is pricing in a slightly higher probability of a

tapering in December or January," said Mike Cullinane, head of

Treasuries trading at D.A. Davidson in St. Petersburg, Florida.

Most analysts expect the Fed to begin reducing its bond

purchases at its March meeting, but some think it could happen

as early as December or January, if employment data comes in

strong.

"Tapering is not if but when, but the Fed wants to see more

data before they taper," said Bret Barker, portfolio manager at

TCW Group in Los Angeles. He anticipates a purchase reduction

will likely occur in March.

Payroll processor ADP said on Wednesday U.S. companies added

215,000 jobs in November, the biggest monthly rise in a year.

This compared with an upwardly revised 184,000 increase in

October and beat the 173,000 gain forecast by analysts polled by

Reuters.

Some analysts use the ADP data to adjust their forecasts on

the government's payroll reading. The U.S. Labor Department will

release its November payroll report at 8:30 a.m. EST (1530 GMT)

on Friday.

Economists polled by Reuters forecast U.S. employers likely

added 180,000 workers in November, following a 204,000 increase

in October.

U.S. employers stepped up hiring in some parts of the

country in October and early November as the economy expanded at

a "modest to moderate pace," the Federal Reserve said on

Wednesday.

The Fed's Beige Book report, a collection of anecdotes from

the central bank's business contacts across the nation, could

bolster the view that the robust growth in payrolls in October

carried over into November.

Other data supporting a Fed withdrawal of stimulus by early

2014 included a contraction in the U.S. trade gap in October,

stemming from record exports, and a 25.4 percent jump in new

home sales in October, the largest monthly gain since May 1980.

On the open market, benchmark 10-year notes last

traded 15/32 lower in price to yield 2.842 percent, up from

2.775 percent late on Tuesday. The 10-year yield touched 2.852

percent, the highest since mid-September.

Thirty-year bonds shed more than 1 point in

price to yield 3.904 percent, up from 3.836 percent on Tuesday.

The yield curve, as measured by the yield difference between

two-year and 10-year Treasuries, grew to 2.55 percent. This

proxy of investors' view on U.S. growth hit its widest level

since July 2011, according to Reuters data.

"Anything positive with the data right now is likely to

cause more selling in bonds and the yield curve to steepen,"

said Mary Beth Fisher, head of U.S. interest rates strategy at

SG Corporate & Investment Bank in New York.

Another month of solid job gains would support ideas that

the Fed will soon trim its third round of quantitative easing,

known as QE3, which began a year ago and involved $85 billion of

monthly purchases of Treasuries and mortgage-backed securities.

Prices on agency mortgage-backed securities fell, too, on

worries about the Fed tapering its bond purchases. The 30-year

3.5-percent coupon MBS backed by Fannie Mae fell

12/32 in price to yield 3.512 percent, up 5 basis points from

Tuesday.

On Wednesday, the U.S. central bank bought $3.18 billion in

notes due 2022 to 2023, part of its QE3 plan to buy $45 billion

of Treasuries in December.
