The London Metal Index hits a record high, market concerns about aluminum supply "black hole".

In the past four weeks, the London Metal Exchange index has risen by nearly 12%, reaching a historic peak at the close of trading on Thursday, driven mainly by the increase in aluminum prices and the recent rebound in copper prices. Since the outbreak of the Iran conflict, the price of aluminum has risen by over 15%, reaching a four-year high on Thursday, mainly due to disruptions in Middle Eastern supply. As of Thursday, the LMEX metal index has risen by 3.6% this week; however, on Friday, most metals have trended lower, with aluminum and copper both falling by 0.4%, while nickel has risen by 1.8%.
