Blue chips were whacked Thursday as concerns about inflation drove long-dated bond yields to their highest level in nearly two years. Tech stocks held the flatline.

The Dow Jones Industrial Average fell 65 points, or 0.58%, to 11,150.70, and the S&P 500 lost 2.64 points, or 0.2%, at 1300.25. The Nasdaq Composite, at a five-year high after the prior session's rally, rose another 3.04 points, or 0.13%, to 2340.82.

Leading the Dow lower were losses of 1.5% or more in Caterpillar ( CAT), Altria ( MO) and 3M ( MMM).

The 10-year Treasury was down 17/32 in price to yield 4.86%, a point not seen since mid-2004 when the Federal Reserve began its rate-hiking campaign. The Fed's string of 15 quarter-point increases has taken the fed funds target rate to 4.75% from 1% in the last 21 months. The 30-year bond sank 1-3/32 and was yielding 4.90%.

Climbing yields create worries about the cost of borrowing, pressure bank profits and can have a cooling effect on economic activity. For example, mortgage rates, which closely track the movements of the 10-year Treasury, tend to rise. Also, corporations issuing debt will generally need to offer higher rates to entice investors. In the last month, the yield on the 10-year has risen 32 basis points from 4.54%, while the 30-year's yield has advanced 40 basis points from 4.50%.

"The market has been hit particularly hard with some sharp steepening of the yield curve," said John Canavan, market analyst with Stone & McCarthy Research Associates. "The economic data has looked pretty strong, and the FOMC has said they see further tightening. Given that, yields have jumped across the curve."

About 1.60 billion shares changed hands on the New York Stock Exchange, with decliners beating advancers by a 9-to-7 margin. Volume on the Nasdaq was 2.18 billion shares, and losers edged winners 8 to 7.

Currency traders sent the dollar lower against the yen and the euro. Precious metals were stronger, with the front-month gold contract rising $13.20 to $591.80 an ounce on Nymex. The 2.3% gain put gold at its most expensive level since January 1981. Silver rose 54 cents to $11.66 an ounce, a move of 5%.

Oil continues to provide a bearish backdrop, with crude starting the day at a two-month high. On Wednesday, the U.N. Security Council authorized a statement giving Iran 30 days to halt uranium enrichment, an action that will spur more anxiety about worldwide oil supplies. May crude finished up 70 cents to $67.15 a barrel, a two-month high.

Meanwhile, unleaded gas rose 4 cents to $1.99 a gallon, its highest point since October, while natural gas rose 3 cents to $7.49 per million British thermal units.
