NEW YORK/ LONDON, Sept 5 (Reuters) -MSCI's global equities index edged down on Thursday as investors anxiouslyassessed mixed economic data while they waited for Friday's crucial jobs report and oilprices held near 14-month lows as demand worries offsetdraws on inventories.

U.S. Treasury yields fell and two-year yields reached a 15-month low after ADP's private sector August jobs data showed fewer new jobs than anticipated.

Thursday's data showed U.S. private employers hired the fewest workers in 3-1/2 years in August while the Julynumber was revised lower, potentially hinting at a sharp labor market slowdown.

The weak data did little to calm investor jitters as theywaitedfor Friday’s U.S. non-farm payroll report for August, which is expected to clarify how fast the U.S. Federal Reserve will cut interest rates at its September meeting.Economists are expecting 160,000 new jobs for August up from 114,000 in July.

While bets have increased to 41% from 34% a week ago that the Fed might kick-off its long-awaited easing cycle with a half percentage point move this month, traders still see a roughly 59% probability that the cut will just be a quarter of a percentage point according to CME Group's FedWatch tool.

On Tuesday,Wall Street indexes suffered their biggest daily losses in almost a month as investor anxiety about the U.S. economy intensified.

Tuesday's decline "did some damage to the psyche of the majority of the bulls and kept people a little more nervous yesterday and today," said Michael James, managing director of equity trading at Wedbush Securities in Los Angeles.

"Today's data was similarly softer making it more likely we're going to have a meaningful move in the market on the jobs report tomorrow morning," said James, noting that "increased anxiety levels will bring about more trimming of positions than adding to positions."

Still, Thursday's data also showed steady U.S. services sector activity in August with the Institute for Supply Management's non-manufacturing purchasing managers index at 51.5 last month compared to 51.4 in July.

But whilethe services data appeared to encourage traders earlier in the U.S. trading session, stock indexes lost steam as investors turned their focus to Friday's data.

On Wall Street, at 03:01 p.m. the Dow Jones Industrial Average .DJI fell 186.52 points, or 0.46%, to 40,789.95, the S&P 500 .SPX lost 13.07 points, or 0.24%, to 5,506.95 and the Nasdaq Composite .IXIC gained 50.34 points, or 0.29%, to 17,134.64.

MSCI's gauge of stocks across the globe .MIWD00000PUS fell 1.38 points, or 0.17%, to 813.67 while earlier in the day, Europe'sSTOXX 600 .STOXX index closed down 0.54%.

In currencies, trading was choppy as investors evaluated the steady services data against the weak jobs number as they looked for clues on the path for interest rates.

"The services numbers relieved some angst about the strength of the economy," said Adam Button, chief currency analyst, at Forexlive in Toronto. "There are no signs of a hard landing in any of the numbers. The market is hanging on every data point right now."

The dollar index =USD, which measures the greenback against a basket of currencies including the yen and the euro, fell 0.16% to 101.10.

The euro EUR= was up 0.2% at $1.1104 while against the Japanese yen JPY=, the dollar weakened 0.22% to 143.42.

In Treasuries, the yield on benchmark U.S. 10-year notes US10YT=RR fell 3.9 basis points to 3.729%, from 3.768% late on Wednesday while the 30-year bond US30YT=RR yield fell 4.6 basis points to 4.0207%.

The 2-year note US2YT=RR yield, which typically moves in step with interest rate expectations, fell 2 basis points to 3.7497%, from 3.77% late on Wednesday.

And a closely watched part of the U.S. Treasury yield curve measuring the gap between yields on two- and 10-year Treasury notes US2US10=RR, seen as an indicator of economic expectations, was at a negative 2.3 basis points.

In energy markets, oil ended the session barely changed as worries about demand in the U.S. and China and a likely rise in supplies out of Libya offset a big, bullish withdrawal from U.S. inventories and a delay to output increases by OPEC+ producers.

U.S. crude CLc1 settled down0.07% or 5 cents at $69.15 a barrel while Brent LCOc1 closed at $72.69per barrel, down 1 centon the day.

Gold prices gained as the U.S. dollar and Treasury yields fell as signs the labor market was losing steam led investors to consider a super-sized rate cut from the Fed.

Spot gold XAU= added 0.85% to $2,515.38 an ounce. U.S. gold futures GCc1 gained 0.57% to $2,507.60 an ounce.
