Storage Industry Cyclicality

Storage Industry Cyclicality is the boom-bust structure described in 存储三巨头破万亿市值，存储超级周期何时能见顶？｜ S10E13. The source says memory products are standardized, fabs require heavy upfront capital, and suppliers have strong incentives to run capacity hard once it exists, even when prices weaken.

The episode’s cycle model is straightforward: demand rises, spot prices jump, customers stockpile, suppliers expand, supply arrives late, demand cools or customers destock, and prices fall sharply. AI changes this cycle by creating more structural demand and stronger Memory Capacity Lock-In, but the source explicitly says it only weakens cyclicality rather than abolishing it.

Key Claims

• Capital intensity and delayed capacity make memory markets prone to overshooting.
• Standardized products make supplier competition more price-sensitive when supply catches up.
• Customer inventory behavior amplifies both shortages and downturns.
• Supplier concentration and capital discipline can reduce destructive expansion, but cannot remove the lag between capex decisions and eventual supply.

Connections

• AI Storage Supercycle - current AI-driven upcycle that modifies the old pattern.
• Memory Capacity Lock-In - customer response to expected scarcity.
• SK Hynix, Samsung, Micron Technology, ChangXin Memory / 长鑫存储, and Yangtze Memory Technologies / 长江存储 - supplier examples.
• AI Hardware Supply Chain Pressure and Memory Chip Shortage - downstream effects of cyclical tightness.
