US 10-Year Treasury Yield Tops 5.2% as Higher-for-Longer Fears Leave New York Stocks Mixed

New York stocks ended mixed on September 24 as long-term US Treasury yields extended their climb above 5%. Investor sentiment came under pressure as resilient US economic data and rising oil prices fueled concern that interest rates could stay high longer than expected.

The Dow Jones Industrial Average fell 161.61 points, or 0.31%, to 51,349.98 on the New York Stock Exchange. The S&P 500 slipped 0.02% to 7,704.13, while the Nasdaq Composite added 0.01% to 26,939.37. The Dow posted its third straight daily decline.

The biggest drag on equities was the sharp rise in market interest rates. The yield on the 10-year US Treasury note climbed to as high as 5.223% intraday, its highest level since June 2007. The 30-year yield reached 5.501%, the highest since June 2004, while the two-year yield rose to 4.941%.

The jump in long-term yields reflected both the strength of the US economy and persistent inflation concerns. Recent purchasing managers' index data for US manufacturing and services pointed to steady economic activity. At the same time, elevated oil prices reinforced the view that the Federal Reserve could maintain its tightening stance for an extended period.

Expectations for another rate increase have also risen quickly. CME FedWatch data showed fed funds futures were pricing in more than a 70% chance of a rate hike in October, up from about 55% a week earlier. CME attributed the shift to strong recent US economic data and hawkish comments from Fed officials.

High oil prices added to the market's burden. Brent crude rose more than 3% to above $106 a barrel, while West Texas Intermediate settled up 2.7% at $94.61 a barrel. Hopes for easing tensions in the Middle East were not enough to pull energy prices lower.

Major indexes pared some of their losses during the session after a report said the US and Iran were discussing ways to gradually de-escalate conflict in the Middle East. The reported agenda included reopening the Strait of Hormuz and easing US economic sanctions on Iran.

For investors, the bigger question is becoming not only whether the Fed raises rates again, but how long long-term yields remain elevated. If Treasury yields stay above 5% for a prolonged period, they could raise mortgage and corporate borrowing costs while also weighing on valuations for risk assets such as stocks.

Jason Stevens, founder of Everton Wealth, said the economy was showing strong resilience while also sustaining inflation concerns and upward pressure on rates. He added that investors should watch the bond market as closely as the Fed's policy-rate decisions in the months ahead.

Among individual stocks, Oracle fell 3.5%. Investor sentiment weakened after concerns emerged over possible delays to a data-center project under construction in New Mexico.

Investors are set to keep watching developments in the Middle East, global oil prices and long-term US Treasury yields. If strong economic data and elevated energy prices persist, inflation concerns could intensify again, keeping expectations for further Fed tightening and upward pressure on long-term yields in place.
