NEW YORK, Jan 6 (Reuters) - U.S. Treasuries prices extended their earlier rise on Monday after a private index of U.S. services industries’ activities unexpectedly fell in December, signaling a slowing in overall economic growth at year-end.
The Institute for Supply Management said its gauge of the U.S. services sector fell to 53.0 last month from 53.9 in November. Analysts polled by Reuters had forecast a rise to 54.5.
Longer-dated bond yields fell to their lowest in about a week after the ISM services data.
Benchmark 10-year Treasury notes were up 8/32 in price to yield 2.965 percent, down 3 basis points from late on Friday.
The 30-year bond was up 20/32 in price, yielding 3.895 percent, down about 4 basis points from Friday.
