Rates are mixed after strong 30-year bond auction

NEW YORK — Interest rates were mixed in the bond market after a government auction of 30-year bonds drew the highest demand since September.

The price of the 30-year bond has jumped Thursday after the $13 billion auction. The spike in its price sent its yield lower.

The auction’s bid-to-cover ratio, which measures demand, was 2.89 percent, the highest level since September.
