Cross-Exchange Basis and Regional Premium Mechanics

LME/SHFE and regional premium spreads transmit financing, logistics, and local demand conditions across base metal markets.

Core Points

  • Cross-exchange basis can widen during logistics stress.
  • Financing and inventory rules affect arbitrage speed.
  • Regional premium shifts often reveal hidden physical constraints.

Case Studies

Case: LME-SHFE Dislocation

A temporary policy and logistics mismatch widened LME-SHFE basis, creating selective arbitrage opportunities.

Case: Import Premium Spike

A sudden increase in regional import premium signaled near-term scarcity despite stable benchmark futures.
