US CPI 4.2%: Renewed Tensions in Iran, Has the AI-Led Rally Stalled?

On June 10 (Eastern Time), New York markets closed sharply lower as a renewed surge in inflation, heightened Middle East geopolitical risks and a steep sell-off in AI-related tech stocks collided. The S&P 500 fell 1.6% to 7,266.99, the Dow declined 1.9% to 49,918.78, and the Nasdaq dropped 2.0%, erasing five weeks of gains.

The biggest catalyst was May’s Consumer Price Index (CPI), which rose 4.2% year-over-year—the highest in three years and up sharply from April’s 3.8%. Although the increase wasn’t a total surprise, it was driven largely by soaring energy costs, stoking fears that the Federal Reserve’s next move could be a rate hike rather than a cut.

Meanwhile, WTI crude oil surged from the low-to-mid $90s per barrel into the high $90s, fueled by U.S. airstrikes following a broader escalation with Iran and renewed instability in the Strait of Hormuz. The 10-year U.S. Treasury yield rose into the mid-4.5% range, intensifying pressure on long-duration debt and dragging down rate-sensitive sectors such as growth stocks, utilities and REITs. Energy and defense shares, by contrast, held up relatively well.

By sector, leading AI and semiconductor names led the downturn. Nvidia, AMD, Broadcom and Micron each slid roughly 3–4% intraday, deepening losses on the Nasdaq. Some institutional investors appear to be taking profits in top AI plays ahead of large IPOs, cashing out gains built up during the recent rally.

On the corporate front, Oracle drew attention after the close with an earnings report that topped expectations. Adjusted EPS came in at $2.11, and revenue surprised on the upside. Still, concerns over hefty AI infrastructure spending and cautious forward guidance produced mixed reactions. Oracle’s shares fell more than 2% in the session before the release, highlighting the valuation drag even on AI-driven growth stories.

Globally, U.S. strikes against Iran and the resulting spike in oil prices seem to be cementing a dynamic that puts simultaneous pressure on inflation, the Fed and U.S. equities. All eyes now turn to next week’s Fed meeting, the subsequent path of inflation, and the eventual stabilization of AI-led names—key variables likely to dictate the market’s next direction.
