ByteWatch Daily Market Digest — 2026-08-02
DRAM supply constraints deepened this week as Samsung and SK hynix moved to lock in customers through long-term agreements, while the NAND/SSD picture showed early signs of divergence — spot index values reflect the split, with DDR5 edging down fractionally (−0.4% to 110.6) and SSDs nudging higher (+1.9% to 101.2) even as upstream NAND export data flashes a cautionary signal.

DRAM: Tight Supply, Binding Contracts, Multi-Year Deficit
Samsung and SK hynix are expanding binding supply deals with module makers amid a prolonged shortage, per The Korea Herald. The urgency is underscored by a stark forecast from Apacer's CEO: DRAM chip supply to module makers could fall more than 70% year-on-year in 2027. UBS has already raised its DRAM price forecast 32% for Q3 2026, with the supply deficit now projected to extend through 2028. TrendForce's latest outlook explicitly contrasts a tight DRAM market against easing NAND conditions heading into 2027. For procurement teams, securing contract pricing or volume commitments on DDR5 modules sooner rather than later carries meaningful risk-management value.

NAND/SSD: Surface Strength, Upstream Cracks
The SSD index gain masks a developing fault line at the upstream level. South Korea's NAND export unit value fell for the first time in nearly ten months, even as finished SSD pricing has held or risen — a divergence worth monitoring closely. Separately, Samsung and SK hynix equities have sold off roughly 30% on looming NAND flash price decline concerns, suggesting the market is pricing in softening ahead. Buyers with flexible SSD procurement timelines may find conditions more favorable in coming quarters, though near-term spot prices remain firm.

HBM: Samsung Closing the Gap
Less directly relevant to standard procurement but worth flagging for AI-infrastructure buyers: UBS projects Samsung will reach 41% HBM market share, overtaking SK hynix. Samsung is also targeting 60–70% of HBM4 capacity under long-term agreements, with hyperscalers including AWS, Microsoft, and Google named as key customers. Capacity being absorbed at the HBM tier continues to constrain broader DRAM wafer availability.
