Tech stocks took a hit in pre-market trading Thursday after the US military launched another wave of strikes against Iran, sending oil prices higher and reigniting worries about inflation and interest rates. Nasdaq futures fell 1%, while the broader S&P 500 futures slipped 0.4%.
What happened?
US Central Command (CENTCOM) reported a fresh round of attacks on Iranian targets, escalating tensions in the Middle East. The news pushed Brent crude oil up 1.3% to $86.06 a barrel, adding to recent gains. Energy markets have been on edge as the conflict threatens supply routes and production in the region.
At the same time, new economic data showed the US economy remains surprisingly strong. Initial jobless claims fell to 208,000, below expectations, and the Philadelphia Fed's manufacturing survey jumped to 41.4, its highest level in years. Several Federal Reserve officials are scheduled to speak later today, and markets will be listening for any hints about the timing of rate cuts.
Why tech is getting hit hardest
The combination of rising oil prices and strong economic data creates a tricky environment for growth stocks. Higher oil prices can feed into inflation by raising transportation and input costs, while also squeezing consumers' budgets. That, combined with a hot economy, makes it less likely the Fed will cut interest rates soon.
Tech companies are particularly sensitive to interest rates because their valuations rely heavily on profits expected years into the future. When rates stay high, the present value of those future earnings shrinks, making the stocks less attractive. This dynamic helps explain why chip and storage names were weak, and why Taiwan Semiconductor Manufacturing Company (TSMC) shares fell 4.2% even after the company reported better-than-expected second-quarter earnings and revenue.
For context, TSMC is the world's largest contract chipmaker and a bellwether for the semiconductor industry. Its strong results would normally boost the sector, but the macro headwinds from oil and rates are proving stronger.
What it means for investors
For everyday investors, the key takeaway is that markets are now juggling two competing forces: a resilient economy that argues against rate cuts, and a geopolitical flare-up that could keep energy costs elevated. When oil rises at the same time as economic data stays firm, investors often worry inflation won't cool as fast, keeping bond yields higher.
Higher bond yields raise the discount rate used to value stocks, which typically pressures long-duration parts of the market like tech and semiconductors. So even strong company results can get overshadowed, and the path for tech-heavy indexes can depend as much on energy headlines and Fed messaging as on earnings.
This pattern has played out across global markets. The Shanghai Composite fell 1.9% as US-Iran strikes continued, while South Africa's rand held near 16.35 as Brent crude rose to $85 on similar tensions. Indian stocks edged up as IT rebounded, but oil stayed near $85.
Looking ahead
Investors will be watching for any further escalation in the Middle East, as well as upcoming Fed speeches for clues on rate policy. The combination of oil above $86 and a strong economy means the "higher for longer" interest rate narrative is likely to persist, keeping pressure on growth stocks.
For now, the market is pricing in a later start to rate cuts than many hoped, and tech investors in particular should be prepared for continued volatility tied to energy prices and central bank messaging.
