Treasury Yields Trade at Almost 3-Week Lows on Bernanke

Treasury 10-year note yields traded at almost a three-week low as Federal Reserve Chairman Ben S. Bernanke said inflation would remain in check as he renewed a pledge to sustain stimulus after the U.S. expansion gains strength.

Benchmark 10-year yields extended earlier declines as data indicating slower growth in Europe and Asia bolstered demand for the safety of U.S. government debt. They briefly rose after the Institute for Supply Management’s U.S. factory index showed growth for the first time since May. The Fed purchased $4.8 billion in Treasuries as part of its Operation Twist program.
