Longer-dated U.S. Treasury debt prices rose in Europe on bargain-hunting after a retreat the previous session following positive U.S. data.

* Traders said some investors were also inclined to take long positions before key non-farm payrolls data due on Friday which bond bulls expect to support expectations that the Fed will adopt more quantitative easing measures.

* U.S. Treasury debt prices dropped on Wednesday after both a U.S. job survey and a service sector index came in slightly better than expected, pushing up stock prices and dampening demand for less risky government debt.

* Guys are looking to buy on dips. Maybe non-farm payrolls report is a catalyst to get us back to higher yields but a lot of people were positioned short and there's been a lot of short covering that's been going on in this market, a trader said.

* Benchmark 10-year U.S. T-notes rose 3/32 in price to yield 2.941 percent, down from 2.955 percent in late U.S. trade.

* The 30-year T-bond jumped 13/32 in price to yield 4.064 percent, 2.4 basis points down from late New York trade. These moves left the 10/30 U.S. Treasury yield curve flat at 112 bps.

* The two-year T-note yielded 0.577 percent, up about 1 bp, underperforming the rest of the curve on profit-taking after the yield hit a record low of 0.52 percent on Tuesday.

* Treasuries have been bolstered by speculation that the Federal Reserve may adopt a more accommodative policy stance at its next meeting on August 10.
