Icya kabiri, ubwiyongere bwihuse bwurwego rushya rwingufu nabwo bwatanze imbaraga zingenzi zo kuzamuka kwibiciro bya aluminium. Hamwe n’isi yose yibanda ku mbaraga zisukuye n’iterambere rirambye, ibyifuzo by’imodoka nshya n’ibindi bicuruzwa bigenda byiyongera. Aluminium, nkibikoresho byoroheje, ifite ibyifuzo byinshi byo gukoresha mubice nkibinyabiziga bishya byingufu. Ubwiyongere bw'iki cyifuzo bwinjije imbaraga nshya ku isoko rya aluminium, bizamura ibiciro bya aluminium.

Amakuru yubucuruzi ya Shanghai Futures Exchange nayo agaragaza imikorere yisoko. Usibye kuzamuka kwamasezerano ya aluminium ejo hazaza, ubundi bwoko bwibyuma nabwo bwerekanye inzira zitandukanye.

Muri rusange, kuzamuka kwa Shanghaiisoko rya aluminiumyashyigikiwe nimpamvu zitandukanye. Izamuka ry’ibiciro fatizo n’iterambere ryihuse mu rwego rushya rw’ingufu byatanze inkunga ikomeye ku biciro bya aluminiyumu, mu gihe binagaragaza ibyifuzo by’isoko ku cyerekezo kizaza ku isoko rya aluminium. Hamwe no kuzamuka buhoro buhoro ubukungu bwisi yose hamwe niterambere ryihuse ryingufu nshya nizindi nzego, isoko rya aluminiyumu riteganijwe gukomeza gukomeza kuzamuka.
