Bond yields just mugged tech stocks

The bond market said “no thanks”

The message from fixed income was loud enough to wake up every growth investor in the building: yields are up, and tech stocks are feeling it.

The U.S. 10-year Treasury yield touched 4.80% Tuesday, its highest level since January 2025, while bond pain spread globally. Britain’s 10-year gilt yield climbed to 5.21%, Australia’s to 5.14%, and even Japan — yes, the place that borrowed for basically free for years — is now paying 3.00%.

Why your favorite tech names suddenly look less cute

This isn’t just a “rates are up” hand-wave. It’s the classic one-two punch for tech:

• Higher yields make future profits worth less today, which hits high-growth stocks hardest.
• Companies are also borrowing more to fund AI buildouts and data centers, so debt just got pricier too.

That’s why the Nasdaq fell 0.7% and the tech-heavy QQQ slipped 1%, while names like CrowdStrike, Astera Labs, Lumentum, Axon, and Teradyne dropped more than 5% in morning trading.

The macro backdrop keeps getting hotter

Last week, Chair Kevin Warsh said inflation still hasn’t slowed meaningfully and the central bank has “work to do.” Traders now see about a 66% chance of a September rate hike. Overseas, the pressure is similar: UK markets are pricing more tightening, and eurozone inflation at 3.3% in August kept another ECB hike on the table for September.

So yeah, this is not one weird red day. It’s a global repricing of money itself.

Big picture: when yields rise this fast, the market stops paying up for “someday” profits and starts asking for cash flow now. Tech investors hate that question almost as much as you hate surprise fees at checkout.
