U.S. government debt prices rose on Friday after the latest nonfarm payrolls report missed expectations.
The U.S. economy added 142,000 jobs last month, the Labor department said. The U.S. 10-year yield plunged from about 2.04 percent to 1.9075 percent after the report was released, an Aug. 24 low. It was last down at 1.988 percent.
Economists expected a steady pace of job growth of about 200,000 in September.
"I do think we are seeing a slowdown, it's hard to ignore that. What do we have? We have the dollar strength weighing on manufacturers and exports. We have oil prices certainly weighing on that sector and other facts," Beth Ann Bovino, senior economist Standard & Poor's told CNBC.
"But I would want to say that we are seeing other strength in the domestic economy. Remember yesterday we saw the construction numbers coming in rather strong and it was also confirmed by this reading," she said.
Two-year yields also fell from 0.6646 percent to about 0.56 percent. It was last at 0.577 percent.
Thirty-year bond yields also plunged from about 2.85 percent to 2.7866 percent before recovering in after-noon trading.
Investors also digested August factory orders, which fell 1.7 percent.
The Fed has said it will base its decision on economic data though it did caution that it held off in September because of international developments, meaning a slowing China and its possible impact on the economy.
