The benchmark index also posted its second straight weekly loss.The Dow Jones Industrial Average slipped 0.2%, and the Nasdaq composite added 0.4%.The majority of stocks on Wall Street fell, and helping to weaken them was rising pressure from the bond market. The yield on the 10-year Treasury climbed to 5% from 4.94% late Thursday after it topped the 5% level early this week for the first time since 2023.Higher yields slow the overall economy by making it more expensive for everyone to borrow money, from the U.S. government to people looking to buy houses to businesses wanting to build AI data centers. They also tend to undercut prices for stocks and other investments.Yields have been climbing in a long march since the COVID pandemic knocked them nearly to zero in 2020. The ascent has accelerated recently because inflation has remained stubbornly high for years.Inflation is well above 3% by several measures. It worsened due to higher oil prices caused by the war with Iran.The price for a barrel of Brent crude, the international standard, got to nearly $110 early this week, up from a little over $70 in July. It has been seesawing since.It briefly dropped below $102 in overnight trading before erasing much of the loss and settling at $103.87, down 0.9% from the day before.Rising oil prices have pushed gasoline prices to $4.47 per gallon, up from $3.20 per gallon a year ago, according to AAA. That is tightening the squeeze on household budgets. Diesel prices are at a record $6.45 per gallon and that has a more direct impact on shipping costs for everything from groceries to clothing.High inflation has been raising expenses for everyone, and more companies are giving details about how much.Steel maker Nucor said late Thursday that it expects to report an increase in profit from its steel mills business in the third quarter from the second because it's able to charge higher prices. But it's also having to absorb higher costs.
