Bond prices finished little changed Friday after a volatile session in which failure to reach a federal budget accord overshadowed another rise in unemployment.

The Treasury's benchmark 30-year bond ended the day largely unchanged, recovering from a sharp decline earlier in the day that pushed prices down about $6 per $1,000. The bond's yield dipped to 8.78 percent from 8.79 percent late Thursday.Bond traders said the rejection of the budget made it unlikely the Federal Reserve would take quick action to lower interest rates to spur the slumping economy, which would boost the value of fixed-income instruments such as bonds.
