New York Copper Squeeze Eases as Exchange Hikes Margins.

The spread between the Comex and LME copper contracts, which had reached over $1,000 a ton, narrowed to about $400. This dislocation in the market has led to efforts to redirect copper supplies to the US. While the situation has eased, there are still signs of significant stress in the market.
