Benchmark 10-year notes, which yielded over 2.50 percent on Tuesday, were up 11/32 in price to yield 2.44 percent in New York trading.

Treasurys pared earlier gains that had 10-year yields at 2.44 percent and briefly traded near unchanged, as data showed the number of Americans filing new claims for unemployment benefits unexpectedly fell last week.
