Shanghai aluminium down

The most-traded June aluminium contract on the Shanghai Futures Exchange closed down 2.2 percent at 14,955 yuan ($2,379.78) a tonne on Friday, but has still gained 3.7 percent this week, its biggest weekly jump since the week ended August 11, 2017. The most-traded July nickel contract on the ShFE closed down 3.2 percent at 104,260 yuan a tonne, after rising to its highest since June 2015 on Thursday. The exchange hiked transaction fees for the July contract from Friday.
Conditions remain "nervous and choppy amid the overhanging uncertainty", brokerage Sucden said in a note, adding that short-term direction was "likely to be headline-driven".
Aluminium is on track for a weekly rise of 9.3 percent in London and is up 24.6 percent so far this month. It climbed 11.9 percent last week in the wake of the Rusal sanctions announced on April 6, its biggest weekly jump since 1988.
