Oil at $110, 10-Year Yield at 5%: The Discount Rate on Growth Stocks Is Rising Again

Brent crude spiked to $109.97 intraday and the US 10-year Treasury yield tested the 5% threshold. What matters is not the numbers themselves but that oil-driven inflation fears are pushing bond yields higher across the globe at once.

This time, it is not just US rates climbing

This is not a selloff confined to US Treasuries. Yields on Japanese and Australian government bonds have climbed to multi-year highs, and European long-term rates have jumped along with them. With oil supply worries colliding with hot producer prices, markets have stopped asking whether US rates are high and started asking a bigger question: is global inflation coming back to life?

US producer prices rose 5.4% year over year in August. With oil now back above $100 a barrel, futures markets are pricing in roughly a 70% chance that the Federal Reserve adds another 25 basis points at its next meeting.

Why 5% matters: it resets the risk-free rate against which stocks are priced

A 10-year yield at 5% is not some magic number that automatically crushes stocks. But when a risk-free government bond pays close to 5%, investors have less reason to pay a premium price for earnings that arrive years from now.

Growth stocks, the kind where a large share of profits sit far out in the future, such as AI companies, software firms and Tesla, are especially sensitive to a rising discount rate. Stocks that have already run up in price, or that trade on high forward price-to-earnings multiples, can see valuations compress even if the underlying earnings do not deteriorate at all. Traders call this multiple compression: the business is fine, but the price investors are willing to pay for the same future dollar shrinks.
