Copper Pushes FTSE 100 Mining Stocks into De Facto Bull Market Amid Tight LME Inventories

Shares of major mining companies listed on the FTSE 100 are posting broad gains, driven by rising copper prices that signal the market is experiencing a de facto bull market in the technical sense of the word.

Copper inventories at the London Metal Exchange (LME) represent the most accurate and critical indicator for measuring the intensity of supply pressures, as these stocks steadily decline, reinforcing upward pressure on prices.

On a structural level, accelerating demand for copper from the renewable energy and electric vehicle sectors is widening the supply-demand gap, making any decline in inventories an immediately impactful event.

This dynamic transforms major FTSE 100 miners into direct beneficiaries of the clean energy transition and global industrial transformation. While optimists estimate that persistent inventory tightness will keep prices elevated and support miners' profits, skeptics warn that any sudden release of reserve stockpiles or a slowdown in Chinese demand could swiftly reverse this equation.

What do these terms mean?

LME (London Metal Exchange): The London Metal Exchange is the global benchmark for pricing industrial metals such as copper, aluminum, and zinc, and its inventories serve as a live indicator of the supply and demand balance.

De Facto Bull Market: A rise in asset prices by 20% or more from their lows alongside sustained positive momentum, without necessarily meeting a single official definition.

Supply Squeeze: A situation where demand exceeds available supply, pushing prices up and igniting competition among buyers to secure available quantities.
