Report coming in:Citi expects official confirmation of a 50% rate by US on copper in weeksCiti expects implementation within 30 daysEarlier:Trump will impose a 50% tariff on copper imports, prices jumpFrom that post:US needs imported copper and will need much more in order to build out the needed investments in the grid, broader infrastructure and electrification. I'm not sure how making it more expensive to import raw materials needed for those factories makes the US more competitive.There is certainly a need to incentivize the supply of mines in the US and elsewhere but a changeable tariff policy hardly achieves this. In any case, it takes many years -- often decades -- to build a copper mine so this will do nothing but drive up costs for the foreseeable future.Its just lucky that I didn't write that post. I woulda said something like 'how stupid is this???' Off to the naughty corner for me! This article was written by Eamonn Sheridan at www.forexlive.com.
