The copper market has experienced a slight easing in tightness following a notable rise in inventories on the London Metal Exchange (LME). Over the course of two sessions, LME copper stocks increased by more than 55,000 tonnes, according to FX Street and ING.

This inventory boost has contributed to a narrowing of the backwardation between cash and three-month copper contracts, signaling a modest relief in supply constraints. The shift suggests a gradual improvement in copper availability amid ongoing demand pressures.

For Japanese markets, where copper is crucial for manufacturing and infrastructure, this development could influence pricing dynamics and supply chain strategies, particularly in sectors sensitive to metal costs.
