Memory Chip Stocks Decline Amid Geopolitical Tensions and Rising Yields
- Memory chip stocks, including Micron and SanDisk, experienced declines on Tuesday, August 18, 2026, with Micron down approximately 5% and SanDisk falling around 6%.
- This downturn is attributed to escalating U.S.-Iran tensions, which have pushed oil prices higher, and a significant increase in Treasury yields, with the 30-year Treasury yield climbing near 5.33%, its highest level since 2007.

Memory chip manufacturers Micron Technology and SanDisk saw their stock prices drop on Tuesday, August 18, 2026. Micron’s stock declined by about 5% to $962.85, while SanDisk shares fell approximately 6% to $1,681.10. Western Digital also experienced a significant drop of 7%. These declines occurred as the broader technology sector moved lower.
The primary factors contributing to this market shift are rising U.S.-Iran tensions and increasing Treasury yields. A 60-day deadline for a peace agreement between the U.S. and Iran expired without a breakthrough on Monday, August 17, 2026, leading to heightened geopolitical uncertainty. This has pushed oil prices higher, with Brent crude rising above $90 a barrel on Tuesday, August 18, 2026. Crude oil prices reached $85.02 per barrel on August 18, 2026, marking a 0.62% increase from the previous day.
Simultaneously, Treasury yields have surged. The 30-year Treasury yield climbed near 5.33%, reaching its highest level since 2007. The 10-year Treasury note yield eased slightly to 4.72% on August 18, 2026, but had been above 4.6% for nearly the past month. These higher yields make growth stocks, often valued on future earnings, less attractive as the cost of capital increases. Despite their recent declines, memory stocks like Micron and SanDisk had experienced substantial year-to-date gains, with Micron up 255% and SanDisk up 653% through Monday’s close. The current market movement appears to be a valuation reset driven by interest rates rather than a change in the fundamental demand for memory chips, which remains strong due to the AI infrastructure buildout.
