Memory chip stocks took a hard hit on Tuesday as geopolitical fears surrounding Iran sent energy prices climbing, rattling South Korean semiconductor makers and dragging their US counterparts down with them.
South Korea’s KOSPI index fell sharply overnight as renewed concerns over the Iran conflict pushed natural gas prices higher. South Korea is one of the world’s largest importers of liquefied natural gas, and its semiconductor fabs run around the clock, relying heavily on LNG-fired power plants.
When energy costs rise, operating margins at these fabs come under pressure. US natural gas futures rose about 7% over the past week, but price increases were sharper in Europe. A sustained Iran-related supply disruption could squeeze Korean chipmakers further.
The two most exposed companies are Samsung Electronics and SK Hynix. Together, they control most of the world’s DRAM supply and a large share of NAND flash production. Both are based and primarily manufactured in South Korea.
SK Hynix fell 11.5% in overnight trading. Samsung dropped 9.9%. Those declines carried over into US markets when trading opened Tuesday.
SanDisk led US losses, falling 8.7% on Tuesday. Micron dropped 8%. Western Digital fell 7.2%, and Seagate slid 5.8%. Lam Research, which supplies equipment to Korean fabs, fell around 5%.

SanDisk’s drop came after a strong recent run. The stock had surged more than 40% in just five trading sessions heading into February, so the pullback came from an elevated base.
Seagate saw the smallest decline among the group. As primarily a hard-disk drive maker, its exposure to NAND flash and Korean fabs is more limited, but it still sold off in what appeared to be a broad “anything storage” trade.
Mizuho analyst Jordan Klein said after the sell-off that the drop mostly reflects South Korean stocks being “overbought,” not a new negative signal on fundamentals. He said heavy selling in Asia is worth watching for its effect on US memory holdings.
Wall Street’s broader view on memory stocks remains positive. Analysts point to strong AI-driven demand, tight supply, and pricing power as the main drivers of earnings growth going forward.
Capacity expansion, however, faces real limits. Clean-room space is constrained, equipment lead times are long, and qualified engineers are in short supply.
Micron posted $13.64 billion in revenue last quarter, beating estimates of $12.88 billion. It is scheduled to report Q2 FY26 results on March 18.
UBS analyst Timothy Arcuri, a five-star-rated analyst, raised his price target on Micron from $450 to $475. He is forecasting next-year EPS of $85, well above the $48 Wall Street consensus.

Lawmakers in the US House of Representatives and Senate met with cryptocurrency industry leaders in three separate roundtable events this week. Members of the US Congress met with key figures in the cryptocurrency industry to discuss issues and potential laws related to the establishment of a strategic Bitcoin reserve and a market structure.On Tuesday, a group of lawmakers that included Alaska Representative Nick Begich and Ohio Senator Bernie Moreno met with Strategy co-founder Michael Saylor and others in a roundtable event regarding the BITCOIN Act, a bill to establish a strategic Bitcoin (BTC) reserve. The discussion was hosted by the advocacy organization Digital Chamber and its affiliates, the Digital Power Network and Bitcoin Treasury Council.“Legislators and the executives at yesterday’s roundtable agree, there is a need [for] a Strategic Bitcoin Reserve law to ensure its longevity for America’s financial future,” Hailey Miller, director of government affairs and public policy at Digital Power Network, told Cointelegraph. “Most attendees are looking for next steps, which may mean including the SBR within the broader policy frameworks already advancing.“Read more
