KASUMBALESA — The global copper market is bracing for a fresh supply shock after catastrophic flooding triggered the collapse of the Kakoso Bridge on the primary export artery linking the Democratic Republic of Congo (DRC) to Zambia. The structural failure, occurring at km 15 on the T3 road, has effectively severed the “lifeblood” of the African copper belt, disrupting a corridor responsible for roughly one-third of the DRC’s 3.5 million tonnes per annum (mtpa) of copper and cobalt exports.
As of Wednesday, March 4, 2026, the Zambia Revenue Authority confirmed that traffic at the Kasumbalesa border crossing—the busiest mineral transit point in Africa—remains heavily restricted.
A Critical Chokepoint Severed
The collapse occurred over the weekend following “unprecedented” overnight rains that overwhelmed local drainage systems. While Zambian road authorities have initiated emergency repairs, the logistical fallout is already rippling through the EV and green energy supply chains.
- Stranded Cargo: Footage from the border shows queues of trucks stretching for dozens of miles. These vehicles carry refined copper cathode and cobalt destined for global markets, primarily via the ports of Durban and Dar es Salaam.
- Alternative Route Strains: While transit has been diverted to the Sakania and Mokambo crossings, these routes are longer and lack the capacity to absorb the 1,000+ trucks that typically pass through Kasumbalesa daily. Logistics experts warn that inland freight rates in the DRC are expected to surge as a result.
- Input Scarcity: The disruption is a “two-way crisis.” The DRC relies on this corridor for imports of sulfuric acid from Zambia—a vital component for hydrometallurgical copper production. A prolonged closure could lead to “hidden” inventory buildup at mine sites and smelters, distorting global supply assessments.
Market Volatility: A Perfect Storm
The bridge collapse comes at a precarious moment for the red metal. Copper prices have been on a volatile trajectory throughout early 2026, driven by a combination of geopolitical tensions in the Middle East and a structural deficit in mine output.
- The $12,000 Threshold: Before the bridge collapse, major banks like Goldman Sachs and UBS had already projected copper to reach $12,000 to $15,000 per tonne by late 2026. This latest logistical bottleneck is expected to act as a further catalyst for price spikes.
- Mining Operations: Major players in the region, including Glencore, Ivanhoe Mines, and CMOC, are monitoring the situation closely. While no mining company has yet declared force majeure, analysts warn that if the “temporary” diversion remains the only option for more than a fortnight, export targets for the first half of 2026 will be missed.
Looking Ahead: The Fragility of the “Green” Transition
The incident underscores the extreme vulnerability of the infrastructure supporting the global energy transition. With the DRC and Zambia serving as the world’s second and sixth largest copper producers respectively, a single bridge failure now has the power to influence inflation rates in Beijing, Brussels, and Washington.
Zambian Infrastructure Minister Charles Milupi stated that a temporary diversion for heavy trucks is expected to be reinforced by Thursday, though full restoration of the Kakoso Bridge could take several weeks. Until then, the “red metal” remains in a race against the weather and the clock.
