Most traders are fixated on copper's explosive rally—and fair enough, it's hitting multi-year peaks. But here's what shouldn't slip under the radar: aluminum just broke into territory that's genuinely rare. We're talking $3,000-per-metric-ton territory, the highest in five years and a level that barely shows up on a 40-year chart. While copper grabs headlines, aluminum's surge tells a parallel story about commodity demand pressure. Whether it's inflation signals, industrial demand, or broader supply concerns, both metals moving in lockstep like this deserves attention. The metals complex is sending messages—worth listening to them.
