International copper prices increased by 0.51% in the week of September 14-19, 2026, reaching $14,535.25 per tonne, the latest foreign trade price data show. The figures, published Monday, record a modest upward movement from the $14,461.25 per tonne recorded the previous week.

The rise continues a pattern of incremental gains recorded over recent weeks. In the week of September 7-12 the metal traded at $14,461.25 per tonne, up 0.77% from $14,350.20 the week before. Earlier, during August 24-29, copper was listed at $14,437.50, a 0.56% increase on the prior week’s $14,356.20.

The Democratic Republic of Congo is a central actor in those price dynamics. The country is Africa’s leading copper producer and its mines yielded 2.8 million tonnes in 2023, placing the DRC as the world’s second-largest copper producer. Because a large share of the minerals used to manufacture high-tech products comes from the DRC, global price movements are closely watched for their implications across supply chains.

The weekly foreign trade price releases provide the routine market benchmark that traders, producers and policymakers use to follow shifts in commodity value. These snapshots show modest but consistent upward pressure on copper in recent weeks, a trend recorded across the consecutive weekly data points.

With the DRC supplying a significant portion of the world’s copper output, continued weekly price monitoring will be important to assess how sustained changes feed into export valuations and the broader mining sector. The published data will remain the primary public reference for tracking those short-term market movements.
