London Metal Exchange faces brief trading halt amid extreme market volatility

  • Aluminium, copper prices fall amid trade disruptions
  • Sharp price swings recorded across contracts

The London Metal Exchange (LME) was hit by a one-hour trading disruption on Friday at a time when global metals markets were already experiencing sharp and erratic price movements. The temporary halt added to uncertainty as participants struggled to respond to rapid intraday swings across key base metals.

The interruption came amid intense volatility in benchmark contracts such as copper, aluminium and zinc, with prices moving aggressively within short periods. The pause in trading heightened concerns among market participants, particularly those with leveraged or short-term positions, as the inability to adjust or exit trades increased exposure during the selloff.

The incident has again brought attention to the resilience of the LME’s trading systems during periods of market stress. While brief outages can occur across exchanges, the timing of the disruption during heightened volatility raised concerns over operational robustness when markets are under pressure.

After trading resumed, selling pressure accelerated across metals markets. Copper prices fell sharply, extending losses recorded earlier in the session, and retreated to near $13,000/t after recently touching record highs. The downturn was not limited to base metals, as precious metals also saw heavy corrections, with gold and silver pulling back significantly from recent peaks.

Overall, the episode highlighted the fragile conditions currently prevailing in metals markets, where extreme price swings, speculative activity and operational reliability are closely linked, amplifying risk during periods of heightened volatility.
