Global price of copper in US dollars per metric ton. Copper is often nicknamed "Dr. Copper" because its price movement is tied to industrial activity and construction — rising copper prices typically signal economic expansion.
Monthly — we refresh daily; new values typically appear on the upstream release calendar.
We gate dateModified updates to actual value changes (threshold: 0.01% absolute or 0.5% relative) to prevent freshness spoofing. If the upstream value hasn't moved, we don't claim we updated the page.
