TREASURIES-US bonds fall on global growth signs

* China data revives global appetite for riskier assets

* Market shrugs off surprise ADP private sector jobs loss

* Traders await ISM manufacturing report (Recasts, adds analyst comments, more context, updates prices)

NEW YORK, Sept 1 (Reuters) - Treasury debt prices fell on Wednesday as investors ventured back into riskier assets and out of safe-haven government debt, emboldened by a rebound in Chinese manufacturing.

Even data showing a surprise loss of U.S. private sector jobs lent only a fleeting bid to Treasuries and left U.S. stock futures still signaling a higher open. For more see [ID:nWEN9253].

"Technically we found a range in notes and bonds and a floor on yields," said Jim Barrett, senior market strategist with Lind-Waldock in Chicago.

Analysts are citing the 2.67 percent area for the benchmark 10-year note's yield as a near-term upper technical level and between about 2.50 and 2.40 percent as a key lower area.

"This news just wasn't negative enough," Barrett said. "The backdrop with the recent data has been so negative anyway so the market is ignoring it," he added.

Wednesday's sell-off stalled a two-day rally that had brought benchmark yields down to near multimonth lows, driven partly by month-end extension buying as portfolio managers adjust portfolios in line with benchmark indexes.

Some of those flows into Treasuries have reversed on this first day of the new month, analysts said.

"Much of yesterday's rally was a function of month-end buying and we saw some pretty solid gains of longer-dated Treasuries, said Kim Rupert, Managing Director, global fixed income analysis at Action Economics LLC in San Francisco. "We also have global equities higher" as appetite for riskier assets returns, Rupert added.

The benchmark 10-year Treasury note's price, which moves inversely to its yield, traded down 17/32 for a yield of 2.54 percent US10YT=RR versus 2.48 percent late Tuesday.

The 30-year Treasury bond traded down 1-13/32 for a yield of just under 3.60 percent US30YT=RR versus 3.52 percent late Tuesday.

Traders were awaiting the Institute for Supply Management report on August manufacturing, due at 10:00 a.m. (1400 GMT). Economists' consensus forecast in a Reuters poll is for a reading of 53.0, down from 55.5 in July but still above the 50 mark which divides expansion from contraction.

Treasuries prices are likely to remain lower unless the ISM data were to surprise with a reading below 50, in which case the 10-year note yield could fall below 2.50 percent, Rupert said. (Editing by James Dalgleish)
