from Bloomberg:
Treasury 30-year bonds fell the most in four months as investors demanded higher-than-forecast yields at today’s auction of $14 billion of the securities with the U.S. slated to sell a record amount of debt this year.
“This is a problem,” said Chris Ahrens, head interest- rate strategist at UBS AG in Stamford, Connecticut, one of 16 primary dealers required to bid in Treasury auctions. “The market required a fairly significant discount to buy the bonds.”
