Treasury 30-Year Bonds Drop for Longest Since January on Europe

U.S. 30-year bonds capped the longest weekly losing streak since January as concern eased that Europe is unable to curb its debt crisis and U.S. retail sales climbed, damping bets the country will fall into a recession.

Treasuries are off to the worst monthly start this year just after completing the strongest quarter since 2008 as appetite for higher-yielding assets overtook demand for a refuge that was spurred by speculation the debt crisis was worsening and the U.S. economy was floundering. Federal Reserve Chairman Ben S. Bernanke will speak next week on the effects of the last recession on central bank policy.
