Long-Dated Treasurys Add Gains

BY MIN ZENG

Prices of Treasury securities rose, setting the stage for gains for the week as a whole, on an unexpected decline in existing-home sales and month-end buying by many bond portfolio managers.

Long-dated securities led the rally, which pushed down the 10-year note's yield to the lowest level in more than two weeks.

For the week, the 10-year note's yield, a benchmark for fixed-rated borrowing costs for consumer and corporate finances in the U.S., has dropped about 18 basis points. The strong demand helped the government sell a record $126 billion in new notes and bonds at historically low borrowing costs.
