European equities declined Wednesday as mining stocks slumped on commodity weakness. The STOXX Europe 600 index fell 0.4% amid broad-based selling that swept across the continent's largest exchanges.
Mining heavyweights drove the downturn. Rio Tinto, Glencore, and other base metal producers tumbled as copper and iron ore prices retreated from recent highs. Copper futures on the London Metal Exchange dropped 1.2%, pressured by Chinese demand concerns and a stronger US dollar that makes raw materials pricier for overseas buyers. Iron ore slid 2.1% as steelmakers in China, the world's largest consumer, signaled slower purchasing activity.
The weakness in commodities reflects broader economic headwinds. China's manufacturing activity showed fresh signs of deceleration, with the official PMI edging closer to contraction territory. This data matters because Chinese demand drives roughly 30% of global copper consumption and 70% of seaborne iron ore. Investors read the slowdown as a signal that global growth may falter, prompting flight-to-safety trades out of cyclical assets.
German industrial stocks also retreated. Siemens Energy fell 1.8% as energy sector volatility persisted. Chemical makers like BASF declined 0.6% following the mining sector's lead, since metals price movements typically precede manufacturing weakness.
Banks bucked the trend slightly. European financial stocks eked out modest gains as bond yields ticked upward on the continent, widening net interest margins. The 10-year German Bund yield rose to 2.47% from 2.41% the prior day, benefiting lenders even as equities suffered.
Energy shares traded mixed after Brent crude oil held above $80 per barrel, though weakness in coal and thermal power demand weighed on utilities.
The selloff was contained. Volume remained light ahead of Thursday's European Central Bank monetary policy decision, with traders cautious ahead of inflation and rate guidance from Frankfurt. Investors positioned for potential policy adjustments depending on fresh eurozone CPI prints due Friday.
The three-day slide left the STOXX 600 testing key technical support at 420 points. A breach below that level could trigger algorithmic selling into institutional stop losses.
