U.S. stocks closed lower on Wednesday as mounting pressure in the bond market pushed Treasury yields to their highest levels in more than twenty years, while investors digested the minutes from the Federal Reserve's September meeting. The Dow Jones Industrial Average fell 341.41 points, or 0.66%, to 51,179.87. The S&P 500 dropped 17.16 points, or 0.22%, to 7,801.77. The Nasdaq Composite declined 61.19 points, or 0.22%, to 27,538.69.

Among large-cap technology names, results were mixed. Amazon gained more than 1%, while Apple, Google and Microsoft posted modest gains. Meta fell more than 2%, and Nvidia and Tesla edged slightly lower. Micron Technology surged more than 4%, Super Micro Computer rose over 3%, and SanDisk climbed about 2%. Meanwhile, SpaceX, Qualcomm and SK Hynix each dropped more than 2%, and CrowdStrike shares slid nearly 5%.

What unsettled investors was the benchmark 10-year U.S. Treasury yield, which climbed to 5.365% on Wednesday, its highest level since April 2002. The 30-year Treasury yield also rose to 5.732%, the highest since May 2002. After the Treasury auctioned $39 billion in 10-year notes, the 10-year yield retreated from its intraday high. The yield was recently little changed, helping stocks pare their losses. Bill Merz, head of capital markets research at U.S. Bank Asset Management, noted that the bid-to-cover ratio and indirect bidder participation were "quite strong." "There is investor interest at these relatively high yield levels compared to what people have been used to over the past 15 to 20 years, but we need to take that with a grain of salt. There are many other drivers that we also need to consider separately," he said. "It was a solid auction."

In addition, the minutes from the Fed's September meeting showed that officials expect to raise rates before the end of the year but gave no hint of a specific timeline. "Regarding the monetary policy outlook following this meeting, most participants judged that it might be appropriate to raise the target range for the federal funds rate once more before the end of the year," the minutes said. "But participants stressed that they would approach each meeting with an open mind, and that decisions at future meetings would depend on newly received information and its implications for the outlook and the balance of risks."

Recent rises in Treasury yields have hit key areas of the market. Bank stocks fell, for example, as investors worried that higher interest rates would dampen lending activity. Shares of Goldman Sachs and Bank of America each dropped 1%. Other bank stocks including Wells Fargo, Citigroup and JPMorgan Chase also closed lower on the day.

International oil prices fell on the 7th. At the close, the November-delivery light crude futures contract on the New York Mercantile Exchange dropped $1.16 to settle at $88.28 a barrel, a decline of 1.3%. The December-delivery London Brent crude futures contract fell 38 cents to settle at $100.20 a barrel, a decline of 0.38%. As of Wednesday, traders saw roughly a 17% probability that the Fed would raise rates at next week's October meeting.
