Treasury 30-Year Bond Yields Have Biggest Weekly Drop Since 2008

Treasury 30-year bond yields had their biggest weekly drop since the depths of the financial crisis in December 2008 on concern the U.S. economic recovery is stalling and Europe’s sovereign-debt crisis is getting worse.

Yields on five-, seven- and 10-year notes fluctuated a day after plunging to historic lows. Government bonds have rallied since the Federal Reserve pledged this month to keep its target lending rate at virtually zero until at least mid-2013 and Standard & Poor’s lowered the top U.S. credit rating for the first time.
