Commentary
First glance at headlines 'Copper imports up 148.3% in May' will stir the bulls and get the bears running for cover. However, further analysis shows that the trend, at least short term, is for falling imports.
While the year-on-year figures do give the impression of continued strong imports; in fact imports of refined copper fell by 8.2% in April and 37.3% in May which puts a whole new perspective on the direction of the industry.
