Copper prices held their ground on Friday, keeping the industrial metal on track for a solid monthly gain. The support came from two familiar forces: a softer US dollar and a continued drawdown in London Metal Exchange (LME) warehouse inventories, according to a Reuters report.
Why a weaker dollar helps copper
Copper is priced in US dollars on global markets, so when the greenback loses value, the metal becomes cheaper for buyers using other currencies. That can nudge demand higher at the margin, especially from big importers in Asia and Europe. The dollar has been under pressure recently, partly due to shifting expectations about when the Federal Reserve might start cutting interest rates. A lower dollar tends to be a tailwind for commodities priced in dollars, and copper is no exception.
The currency effect is often modest, though. Traders say the bigger story for copper right now is physical tightness — the actual availability of metal in warehouses that back LME contracts.
Inventories keep shrinking
Total copper stocks in LME-registered warehouses fell to 255,400 tons, down 21.38% in July. That is a sharp decline in just one month, and it signals that demand for physical copper is absorbing available supply. Even more telling, Reuters noted that more than 60% of the remaining inventory is under “canceled warrants” — a technical term meaning the metal has been earmarked for withdrawal. In plain terms, that copper is already spoken for and will soon leave the warehouse, leaving even less available to the market.
When a large share of warehouse stock is canceled, it often points to strong physical buying, possibly from manufacturers, wire and cable producers, or construction firms. It can also reflect traders positioning for tighter supply ahead. Either way, it reduces the buffer of readily available metal, which tends to support prices.
What this means for investors
For everyday investors, copper is a useful barometer of global economic health. The metal is used in everything from electrical wiring and plumbing to electric vehicles and renewable energy infrastructure. When copper prices rise, it often signals that industrial demand is solid and that economies are growing. When they fall, it can hint at slowing activity.
The current tightness in LME inventories suggests that demand for physical copper remains resilient, even as some parts of the global economy show signs of cooling. That could be a positive signal for companies in the copper supply chain, from miners to recyclers. However, copper prices are also sensitive to broader macroeconomic forces, including interest rates, China's property sector, and the pace of the energy transition.
Investors should also keep an eye on the dollar. If the Fed cuts rates later this year, the dollar could weaken further, which would likely give copper another boost. On the other hand, if inflation stays sticky and the Fed holds rates higher for longer, the dollar could firm, putting downward pressure on copper.
What to watch next
Beyond the dollar and LME stocks, traders will be watching for any signs of a rebound in Chinese demand, as China is the world's largest consumer of copper. A pickup in Chinese manufacturing or infrastructure spending could tighten the market further. Conversely, a slowdown there could ease some of the pressure.
Also on the radar: the upcoming US jobs report and inflation data, which will shape expectations for Fed policy. Any surprises could move the dollar and, in turn, copper prices.
For now, the combination of a softer dollar and shrinking inventories has copper in a sweet spot. But as with any commodity, prices can turn quickly, so investors should stay informed and avoid making decisions based on short-term moves alone.
