Lead
The 10-year Treasury yield reached an intraday high of 5.29% on Tuesday, its highest level in 19 years, before easing to about 5.23%. In stock market today trading, the S&P 500 closed at 7,670.84 as equities absorbed the move in borrowing costs. Traders now turn to the August reading on core PCE inflation and the final estimate of second-quarter GDP, both due today, for evidence on whether the bond selloff has further to run.
What Happened to Treasury Yields?
The 10-year yield climbed to 5.29% during the session, then pulled back roughly 6 basis points to about 5.23%. A basis point is one hundredth of a percentage point. The intraday peak is the highest for the benchmark since 2007.
The move extends a steep rise across 2026. The yield began the year near 4.2% and sat just below 4.8% at the start of September. Sticky inflation and heavy borrowing by the federal government have pushed it higher. Corporate issuance from companies financing artificial intelligence data centers has added to the supply of long-dated debt.
The 10-year yield sets the reference rate for mortgages, corporate bonds and much of the wider credit market. A rise of this size lifts financing costs across the economy and raises the return investors demand for holding equities instead of risk-free bonds.
Why Did the S&P 500 Hold Near 7,670?
The S&P 500 held near the 7,670 level because the intraday retreat in yields limited the pressure on equity valuations. The index closed at 7,670.84 after a month in which surging bond yields, elevated oil prices and concerns over the pace of AI spending have shaped trading.
Higher yields weigh most on long-duration growth stocks, whose earnings are weighted toward the future and are discounted at a higher rate when Treasuries pay more. Broad index products such as the SPDR S&P 500 ETF Trust (SPY) reflect that pressure as well, since a small group of mega-cap technology companies carries a large share of index weight.
A 10-year yield above 5% also changes the relative appeal of stocks. Government debt now offers a yield that competes with the earnings return implied by equity prices, which narrows the margin for disappointment in corporate results.
What Are Traders Watching Today?
Traders are watching two releases: August core PCE inflation and the final estimate of Q2 GDP. Core PCE strips out food and energy and is the price gauge the federal reserve uses for its 2% inflation target. It carries particular weight when interest rates and bond yields are both elevated.
Final Q2 GDP revises the prior estimate of growth for the April-June quarter. A stronger reading would reinforce the case that the economy can absorb higher borrowing costs. It would also keep pressure on yields, since firm growth reduces the likelihood of policy easing. A softer reading would raise questions about how much demand remains beneath the inflation figures.
How Could the Data Move Markets?
The data could move markets in two directions, depending on how the readings compare with expectations.
- Cooler inflation would ease the pressure that has driven yields up since July. It would support the argument that the recent selloff overshot, and it would give equities room to recover.
- Hotter inflation would reinforce the view that price pressures remain entrenched. A retest of the 5.29% high would then be likely, with the yield's 19-year peak as the next reference point for bond and stock investors.
The path of the 10-year yield matters beyond the day's trading. Sustained yields above 5% raise the cost of refinancing corporate debt, weigh on housing activity and increase interest payments on federal borrowing, which is already large.
Market Context
Month-end positioning adds to the volatility. September has been dominated by the rise in yields, high oil prices and headlines on AI investment. Each has fed into inflation expectations and into the valuation of technology-heavy indexes. The session on Tuesday showed how closely equity direction now tracks the bond market.
Outlook
The 10-year Treasury yield sits near 5.23%, just below its 19-year high of 5.29%, and the S&P 500 stands at 7,670.84. Today's August core PCE report and final Q2 GDP estimate are the next tests. The results will help set expectations for the federal reserve and for the direction of borrowing costs through the fourth quarter.
