Bond Yields Just Hit a 24-Year High, and Wall Street Is Feeling It

Keypoints:

• The 10-year Treasury yield touched 5.29% on September 29, its highest intraday level in roughly 24 years
• The 30-year Treasury yield climbed above 5.6%, a level last seen in 2002
• The S&P 500, Dow, and Nasdaq all closed lower as rising yields pressured stocks
• Smart ring maker Oura postponed its US IPO the same day, citing market uncertainty
• The S&P 500 remains up 12.1% for the year despite a slight monthly loss in September

The bond market's slow climb turned into a genuine milestone this week. The 10-year Treasury yield touched 5.29% on September 29, its highest intraday level in roughly 24 years, while the 30-year yield pushed above 5.6%, a level last reached back in 2002. Since yields and bond prices move in opposite directions, that climb reflects investors demanding a much bigger premium to hold long-term government debt than they have in decades.

Stocks felt the pressure directly. The S&P 500 slipped 0.2%, the Dow dropped 0.3%, and the Nasdaq fell 0.1%, with rising yields undercutting gains from several large technology stocks that would otherwise have lifted the market. Higher long-term yields make future company earnings worth less in today's dollars, a dynamic that tends to hit growth and tech stocks hardest, and this week's move fits that pattern closely.

The ripple effects reached beyond the stock market too. Oura, the maker of wearable smart rings tracking sleep and heart health, postponed its long-planned US IPO the same day, despite what CEO Tom Hale described as strong investor demand for the 50 million shares it had marketed between $40 and $44 apiece. "We have the luxury of choosing our moment," Hale said, a decision that reflects how unsettled bond markets can freeze IPO timing even for a company with genuine buyer interest.

Even with the pressure, the broader market's year-to-date picture stays positive. The S&P 500 is up 12.1% for 2026 so far, and Tuesday's dip came after a 2.6% gain in August, a reminder that a rough week of yield-driven selling doesn't automatically erase a strong year underneath it.
