LME Curve Structure and Inventory Signals

Base metals price discovery depends on cash-forward spreads, inventory location, and warehouse warrant behavior.

Core Points

  • Cash/3M spread indicates prompt tightness or surplus.
  • Inventory draw pace often matters more than level.
  • Regional premium behavior can diverge from headline exchange price.

Case Studies

Case: Cash Spread Flip

A rapid inventory draw moved the market from carry to backwardation, changing both hedging cost and physical bidding behavior.

Case: Warehouse Location Premium Shift

Regional stock concentration drove divergent local premiums despite stable global inventory totals.
