S&P MARKETSCOPE: Bonds rebounded from losses on Thursday on back of sentiment that China's yuan revaluation would not hurt the country's demand for U.S. Treasuries as much as initially thought.
The 10-year note rose 15/32 to 99-08/32 for a yield of 4.22%. The 30-year bond climbed 33/32 to 114-07/32 for a yield of 4.44%.
The shooting of a suspected bomber in London just a day after explosions there also provided price support on back of a safety bid.
Most still expect yields to rise in the future given the Fed's hawkish tone in the FOMC minutes from the June meeting.
