Wall Street ended lower Tuesday, led by another sharp retreat in technology and semiconductor shares. The S&P 500 fell 0.69% to 7,691.76, while the Nasdaq Composite lost 1.33% and the Dow Jones Industrial Average slipped 0.22%. The Philadelphia Semiconductor Index dropped nearly 5%, with Nvidia, Micron and other chip stocks among the main drags.
The reversal comes less than a week after the S&P 500 closed at a record 7,798.99 on Aug. 13. That rally had been supported by softer inflation data and renewed strength in large technology stocks, but higher bond yields have quickly changed the backdrop for equities.
Long-Term Bond Yields Return to Decade Highs
The biggest pressure is coming from the long end of the bond market. The U.S. 30-year Treasury yield climbed as high as 5.327% on Tuesday,its highest level since 2007, while the 10-year yield briefly traded above 4.72%.
The move has not been limited to the United States. Japan's 10-year government bond yield reached 2.945%, a 30-year high, while government borrowing costs in several European markets have also climbed to levels last seen well over a decade ago.
Longer-dated bonds are being hit particularly hard as investors demand more compensation for inflation, fiscal deficits and the growing volume of debt coming to market. In the U.S., the gap between long-term yields and short-term policy rates has widened substantially, reflecting the market's growing concern about risks further out on the yield curve.
Heavy corporate borrowing is adding another layer of pressure. SIFMA data shows U.S. corporate bond issuance reached $1.681 trillion through July, up 26.9% from the same period last year. Corporate issuance totaled $2.2 trillion in 2025, meaning 2026 remains on course to challenge or surpass that record.
Higher Oil Prices Add to the Inflation Problem
The bond selloff has also coincided with renewed tension in the Middle East. Brent crude has moved back above $90 as uncertainty surrounding the U.S.-Iran conflict and shipping through the Strait of Hormuz keeps supply concerns elevated. Higher energy prices complicate the inflation outlook and make long-duration bonds as well as richly valued growth stocks: more sensitive to changes in rate expectations.
That combination has been particularly painful for technology shares. Higher long-term yields increase the discount rate applied to future earnings, which tends to weigh most heavily on companies whose valuations depend on profits expected years from now.
Asian markets also followed Wall Street lower. Semiconductor weakness was especially visible in South Korea and Japan, extending a broader pullback in AI-related trades that had been among the strongest parts of the market this year.
Fed Minutes Become the Next Market Test
Investors will now turn to the Federal Reserve's minutes from its July 28–29 meeting, scheduled for release Wednesday at 2 p.m. ET. The document could provide more detail on how policymakers are balancing softer recent inflation data against persistent price risks and rising energy costs.
For stocks, the immediate question is whether the bond market stabilizes. The S&P 500 remains only modestly below last week's record, but another leg higher in long-term yields could put additional pressure on technology shares and turn what has so far been a short pullback into a broader correction.
