SK hynix just rewrote the rules on how memory chips get sold. The South Korean semiconductor giant is stripping price caps from select long-term supply agreements, a move that lets contract prices float freely with the spot market when supply gets tight.

The company is also stretching deal durations from the industry-standard one year to three-to-five year commitments. Samsung is reportedly following the same playbook on contract length.

What’s actually changing

Traditionally, long-term agreements in the memory business come with guardrails. Price caps protect buyers from getting gouged during shortages. Price floors protect sellers from getting crushed during gluts.

SK hynix is tearing up the top half of that handshake. By removing price caps, the company can fully pass through spot market price increases to its contract customers during supply-constrained periods. In English: when chips are scarce and prices spike, SK hynix’s customers will now pay whatever the market demands rather than a pre-negotiated maximum.
