Despite chip stocks advancing and renewed optimism surrounding artificial intelligence, the blue-chip Dow Jones Industrial Average, the Nasdaq, and the S&P 500 all closed the session in negative territory. Both the Dow and the S&P 500 dropped 0.5%.
Major Stock Indexes Slip as Treasury Yields Climb to Multi-Year Highs
The 30-year Treasury yield rose to 5.31%, marking its first close above 5.3% since June 2007. Meanwhile, the benchmark 10-year Treasury yield ticked higher to 4.725%, up from 4.695% on Friday. The 2-year Treasury note yield rose to 4.182%. Yields and bond prices move inversely to one another, with yields rising when prices fall.
Geopolitical Tensions and Rising Oil Prices Fuel Market Pressures
The upward pressure on yields was accompanied by a jump in global energy prices as geopolitical concerns escalated. West Texas Intermediate futures gained 2.6% to settle at $84.50 per barrel, while global benchmark Brent crude advanced to close above $90 a barrel according to CNBC. Brent crude futures climbed following reports from Iranian media that an oil tanker had been seized in the Strait of Hormuz. State-linked Fars News Agency reported on X that a tanker had been detained and noted that Iran requires shipowners transiting the waterway to pay transit fees, though the report could not be immediately verified.
Market anxieties were further intensified as the 60-day deadline for the United States and Iran to secure a peace deal approached expiration, with Iran ruling out an extension according to state media. A senior Iranian official also indicated that Tehran would take an offensive stance if diplomacy with the U.S. fails.
Fiscal Deficits and Inflation Concerns Weigh on Bond Markets
While geopolitical events drove short-term volatility, market strategists pointed to broader fiscal and structural pressures impacting the fixed-income market. Strategists at Barclays noted that the rising rates reflect concerns over the U.S. budget deficit, high levels of debt issuance related to artificial intelligence competing with Treasurys, and higher term premiums.
What is notable today is not the existence of these pressures, but that they appear strong enough to overwhelm individual soft-data releases,
said Anshul Pradhan, head of U.S. rates research at Barclays Capital, in a note. Three independent releases argued for lower yields this month; long end yields moved higher anyway.
Additional pressure stemmed from fiscal reports indicating that the U.S. budget deficit reached its highest monthly level in more than five years, driven by rising Medicare costs and interest on the federal debt. Anthony Saglimbene, Ameriprise chief market strategist, noted that investors are increasingly evaluating Treasury securities through the lens of longer-term fiscal sustainability rather than strictly focusing on inflation, monetary policy, and growth.
Upcoming Economic Data and Federal Reserve Focus
Investors are now turning their attention toward upcoming economic catalysts later in the week. Major retailers including Target and Walmart are scheduled to report earnings, offering investors further visibility into the health of U.S. consumers.

Additionally, markets are awaiting the release of the minutes from the Federal Open Market Committee’s July meeting. At that meeting, the Federal Reserve voted 9-3 to hold interest rates steady at between 3.5% and 3.75% for the fifth consecutive meeting on July 29. The three dissenting committee members—Beth Hammack of Cleveland, Neel Kashkari of Minneapolis, and Lorie Logan of Dallas—had called for a 25 basis point rate hike.
