Long-term US government debt yields jump after disappointing demand for 30-year bonds in an auction just hours after the release of higher-than-expected inflation data. A 2.375% coupon for the bonds reveals a “sloppy demand,” Spartan’s Peter Cardillo says, linking the result to June’s CPI. “It shows investors are not going to put up with inflation for very long,” he says. The 30-year yield rises to 2.049%, up from 1.958% earlier. The 10-year also rises to 1.432% from an intraday low of 1.331%.
