Aluminum just hit a three-year high—breaking past $3,000 per ton for the first time since 2021. This isn't random noise; it's part of a broader metals rally that signals something meaningful about global demand, supply constraints, and inflation dynamics. When industrial metals surge like this, it typically reflects either strong economic growth expectations or tightening supplies. Either way, crypto traders watch commodity moves closely since they often precede or correlate with broader market sentiment shifts. The question now: is this a temporary spike or the beginning of a sustained uptrend in hard assets?
