The yield on the latest 30-year bond supply, however, came in nearly 2 basis points than what traders had expected, signaling reduced safe-haven demand with Thursday's rebound in stock and oil prices from losses, analysts said.
The ratio of bids to the amount of 30-year bonds offered was 2.29, the weakest since August.
In December, the bid-to-cover ratio, a gauge of overall auction demand, was 2.42.
