30-year U.S. Treasury yields hit a new high in 19 years—will this really drag down the U.S. stock market?
The main pressure on the U.S. stock market recently is still coming from U.S. Treasury yields continuing to rise.
Yesterday, the 30-year Treasury yield surged to its highest level in 19 years, which had a big impact on market sentiment. As long-term interest rates rise, the cost of capital increases, and stock valuations are also pressured—especially for technology stocks and semiconductors that had gained a lot earlier.
Yesterday, all three major U.S. stock indexes were generally weak overall. The Dow fell slightly, the S&P fell more noticeably, and the Nasdaq faced the most pressure. The semiconductor sector was also hit hard; chip stocks broadly pulled back. Names like <a> </a>SanDisk $SNDK —tech stocks that were more volatile earlier—are also likely to be repriced by capital when interest rates move higher. Although Apple $AAPL is a more core-weighted stock, as long-end rates keep rising, sentiment toward valuations across the entire technology sector will be affected.
Rising Treasury yields affect the U.S. stock market mainly in two ways.
First, capital will reassess risk versus return. Previously, people were willing to buy growth stocks because they expected large growth room in the future. But now that long-term Treasury yields are higher, the appeal of low-risk assets has strengthened, and some funds may move out of overvalued stocks.
Second, technology stock valuations will be recalculated. In areas like AI, semiconductors, and software, many valuations are built on future growth. The higher the interest rates, the more cautious the market becomes in valuing future profits.
But this doesn’t mean the U.S. stock market will necessarily be directly “crashed.”
What matters next is whether the 30-year Treasury yield can hold steady. If it only spikes higher in the short term, the U.S. stock market may be more likely to see a phased correction, especially with sectors that had big gains earlier first pulling back. If Treasury yields continue rising—and the market starts to worry that high long-term rates will persist—then the U.S. stock market, particularly the Nasdaq and the semiconductor sector, could face additional pressure.
So right now, it’s more like a valuation stress test. When Treasury yields hit new highs, it doesn’t necessarily mean the U.S. stock market will immediately fall apart, but it will force the market to reconsider how high technology stocks and other high-valuation assets can still be priced.
