DDR4 Price Collapse: 100 RMB Drop Signals Bubble Burst

The bubble was inflated by pure speculation, not fundamental scarcity. In October, 16GB DDR4 modules in Huaqiangbei surged 160% as traders bet on perpetual shortages. This wasn't a supply-demand correction; it was a capital flow chasing momentum, with prices resetting daily in the world's largest electronics market.

That flow has now reversed violently. This week, prices for 16GB modules fell from 700-800 yuan to 650 yuan as traders rushed to unload inventory. The collapse is a direct reallocation of capital from speculative trading back to the underlying supply-demand reality. The market had priced in a shortage that never materialized, and the correction is brutal.

This DDR4 implosion is part of a broader, more severe supercycle. While DDR4 is oversold, the fundamentals for commodity memory are tightening. Contract prices for DRAM and NAND have almost doubled, and spot prices for DDR5 chips hit $6.84. The bubble burst in DDR4 is a warning shot, but the structural supply crunch for all commodity memory is just beginning.

Capital Flow: AI Demand vs. Commodity Supply

The core driver is a massive reallocation of manufacturing capacity. DRAM producers are shifting output to high-bandwidth memory (HBM) for AI accelerators, starving the commodity market. This structural shift is the root cause of the ongoing supercycle, with contract prices for DRAM and NAND products having almost doubled recently.

The resulting supply squeeze created a hoarding environment. Buyers, fearing shortages, purchased immediately upon receiving quotes, fueling spot price spikes. This dynamic was visible in the severe hoarding reported in November, where spot prices for DDR5 chips surged 30% in a week. The market moved to daily price resets, with traders in Huaqiangbei noting "a new price every day" as the surge accelerated.

This speculative frenzy has now hit its limit. The bubble burst is a direct correction as capital flow reverses. Prices for common DDR4 modules are now declining sharply, with 16GB modules falling from 700-800 yuan to 650 yuan. This collapse signals that the artificial shortage fears have been met with actual supply, and the market is reverting to earlier-year levels. The structural supply crunch for commodity memory, however, is just beginning, with normalization not expected before 2027-2028.

Catalysts and What to Watch

The immediate trigger is a correction, not a reversal. The recent price drops for DDR5 kits, with some falling up to $100 per kit, appear driven by a single event: Google's TurboQuant algorithm. Yet analysts caution this is likely evolutionary, not revolutionary. The impact may be temporary volatility, not a fundamental shift. The key near-term metric is price stability. If the declines hold, it signals a genuine shift in sentiment; if they reverse, the speculative bubble may simply be resetting.

Monitor capital flow from memory manufacturers. This week, stock prices for memory manufacturers dropped significantly following the algorithm's unveiling. That move away from speculative memory trades is a clear signal of shifting market sentiment. Watch for sustained weakness in these stocks to confirm the correction is broad-based and not just a reaction to one news item.

The long-term metric is the normalization timeline. Supply of commodity memory is set to worsen in early 2026, with normalization unlikely before 2027-2028. The structural shift to HBM production for AI accelerators is the root cause. Until new capacity comes online, likely in late 2028, the market will remain under severe supply pressure. Any near-term price relief is a temporary reprieve in a longer-term supercycle.
