Shanghai cif copper premiums down in squeezed market

Shanghai cif copper premiums were down by around $5 to $120-125 per tonne on Wednesday May 21 amid an unfavourable arbitrage and a large backwardation in the London market.

Shanghai cif copper premiums were down by around $5 to $120-125 per tonne on Wednesday May 21 amid an unfavourable arbitrage and a large backwardation in the London market.

Premiums fell this week and transactions are flat,” a physical trader told Metal Bulletin. “Warehouse cargoes were sold at a premium of around $120 while B/L cargoes were slightly higher.”

“It is obvious that long positions are squeezing the market currently; traders build up large long positions in the LME market while purchasing actively on the spot market,” another physical trader said.

“This ‘squeezing’ activity boosted both LME and spot copper price with the large 3-month to cash backwardation in LME lending support.”

The LME cash to 3M backwardation was at $48 per tonne on Wednesday May 21.

“Under these circumstances, shorts have to leave the market either by closing their positions suffering losses or buying spot cargoes at a high price,” he added.

“Though the LME copper price fell on Tuesday and prompts have passed, we don’t think the squeezing has ended. A big drop in LME open interest and backwardation will be a sign of the squeeze ending,” he said, adding, “If that happens, copper price will plummet.”

“Large imported cargoes flew to China from the LME with traders keen to sell,” another commodity trader said. “The arbitrage and backwardation, however, are making it costly to store cargoes, resulting in light transactions and falling cif premiums.”

“I think this squeezing may continue for a while and our company is also seeking opportunities to benefit from the large backwardation,” a senior futures trader at one of China’s largest copper trading company told Metal Bulletin.

Copper’s long-term outlook is constrained by the industry’s limited ability to bring new supply online fast enough to meet rising demand, with permitting delays, higher capital costs and policy risks slowing project development, industry executives said at the FT Commodities Global Summit on Wednesday April 22.
Capital is flowing back into junior mining, but selectively. Investment is increasingly favouring development‑stage assets with clearer paths to production, supported by government funding and strategic partnerships. While demand for critical minerals underpins the cycle, early‑stage explorers continue to struggle for capital as investors prioritise discipline, ESG alignment and near‑term cash flow.
Copper in concentrate production from Ivanhoe Mines' Kamoa-Kakula complex in the Democratic Republic of Congo (DRC) fell to 61,906 tonnes in the first quarter, down by 54% from 133,120 tonnes a year earlier, with the company now evaluating local third-party concentrate purchases to advance the ramp-up of its on-site smelter, according to an April 13 production release as the market focused its attention on the impact of global sulfuric acid shortages during CESCO Week in Chile from April 13-17.
China's planned sulfuric acid export ban from May 1, historic lows for copper concentrates treatment and refining charges (TC/RCs) and a fragmenting 2026 benchmark system dominated CESCO Week 2026 in Santiago from April 13-17.
The proposal would align the index more closely with physically traded volumes in the region, and enable it to adjust to evolving market conditions. This proposal follows an observed widening of the spread between trader and smelter purchase components of the index and is aligned with a majority of market feedback.
