Nasdaq semiconductor stocks lead tech sell-off as memory chip crisis deepens amid Middle East turmoil

A collapse in smartphone demand is compounding geopolitical anxiety for chip stocks, with the sector's equipment makers caught in the crossfire
Technology stocks bore the brunt of a broad market sell-off on Tuesday as escalating conflict in the Middle East drove oil prices sharply higher and stoked fears of renewed inflation, but within the carnage a more specific and troubling trend was emerging for the semiconductor sector.
The Nasdaq fell more than 2% as Brent crude topped $84 a barrel after Iran's Revolutionary Guard stated the Strait of Hormuz was closed to shipping, a development that sent energy costs surging and raised the prospect of higher interest rates, the traditional enemy of high-multiple technology stocks.
Yet the damage to chipmakers and their equipment suppliers ran deeper than geopolitics alone.
Research firm IDC warned that the global smartphone market faces its largest year-on-year decline on record in 2026, with volumes forecast to fall 13% to their lowest level in a decade, driven by what the firm described as a "tsunami-like shock originating in the memory supply chain."
The cause is a severe shortage of memory chips for consumer electronics manufacturers, as producers including Micron have redirected output towards higher-margin data centre customers.
The consequences rippled visibly through the Nasdaq's worst performers. Micron fell nearly 7%, while data storage companies Western Digital and Seagate, both heavily dependent on consumer device demand, dropped sharply alongside them.
Equally telling were the losses among semiconductor equipment makers, with ASML, KLA Corporation, Applied Materials and Lam Research all falling between 5% and 6%, a sign that investors are pricing in a slowdown in orders for the industrial machinery used to manufacture chips.
The convergence of a geopolitical shock with a structural demand collapse in consumer electronics created an unusually concentrated sell-off, with the entire semiconductor supply chain, from chip designers to equipment vendors to storage manufacturers, moving sharply lower in unison.
