The rout in copper that began on Friday March 7 continued the following week on selling that originated in China, sparked by the default of a small solar cell manufacturer – the first such corporate default in the country, fears about demand, and parallel selling in iron ore and rebar.

The arbitrage window for the red metal as tracked by Metal Bulletin, negative for all but a small part of this year, moved out to beyond minus $200, reflecting the weakness of sentiment about China.

Against the backdrop of fast-falling copper prices, in an excellent interview and presentation at Metal Bulletin’s copper conference in Milan Citrine Capital partner Andreas Hommert explained how the depreciating yuan and the negative arbitrage could lead to Chinese smelters exporting cathode.
