Treasury Department auctions $15B in 30-year bonds at a high yield of 2.615%

U.S. Treasurys fell Thursday amid choppy stock trading and after the Treasury Department saw weak demand at a 30-year bond auction.

The yield on the benchmark 10-year Treasury note, which moves inversely to its price, rose to 1.757 percent, while the yield on the 30-year Treasury bond also climbed to 2.608 percent.

The Treasury sold $15 billion in 30-year bonds at a high yield of 2.615 percent. The bid-to-cover ratio, an indicator of demand, was 2.19 compared with a recent average of 2.34.

Indirect bidders, which include major central banks, were awarded 59.7 percent, versus a recent average of 59 percent. Direct bidders, which include domestic money managers, bought 8.8 percent, compared with a recent average of 11 percent.

The Dow Jones industrial average on Wednesday logged its biggest daily fall since February, Reuters data showed, after disappointing retail earnings rattled investors' nerves.

The three major U.S. averages were mixed Thursday in choppy trade.

Any more misses in retailers' earnings Thursday could stir up bigger concerns about the consumer. Retail plunged and the SPDR S&P Retail ETF (XRT) was down 4.4 percent in its worst day since August 2011. Macy's was the latest retailer to disappoint with worse than expected sales and a disappointing forecast.

On Thursday, investors digested two key data sets. Weekly jobless claims rose 20,000 to 294,000. Economists polled by Reuters had forecast initial claims slipping to 270,000 in the latest week. Meanwhile, U.S. import prices rose for a second straight month in April.

Wednesday saw another strong government auction, with $23 billion in 10-year notes seeing strong demand from foreign buyers. The notes were sold with a yield of 1.71 percent.

In oil markets, Brent crude traded at $47.91 a barrel, 0.7 higher percent, while U.S. crude settled 1 percent higher at $46.70.
