Build-up of US copper stocks leading to apparent market tightness

Copper prices have hit record high after record high in 2026, and are approaching USD 15,000/t as of 10 September. This is despite 2025’s multi-year high surplus and 2026 looking likely to be a broad surplus too.  Part of the reason prices are not reflecting the strong surplus is that huge flows into the US are making the market feel significantly tighter than it is.  In 2025, so much copper went to the US that Benchmark assessed the market as “feeling” 700kt tighter in 2025 than the actual surplus, and Benchmark expects the perceived tightness to be 880kt lower than the actual surplus in 2026.

China reportedly set to pause BESS cell capacity approvals

China is reported to have temporarily paused approvals for new battery energy stationary storage (BESS) cell production projects. The pause is part of increased measures by China to curb overcapacity and oversupply in the BESS cell market and is likely part of a review of existing and planned projects, but only applies to facilities that are yet to begin construction. This follows on from MOFCOM’s cessation of the lithium ion battery industry’s eleven year tax exemption and the elimination of export tax rebates for battery products. Those tax policies served more to encourage producers to limit output, rather than pause business activities. “If implemented, this new legislation would represent a significant escalation in China’s attempts to control the surge in BESS cell production witnessed across 2025 and 2026,” said Evan Hartley, research manager at Benchmark.

What is really going on with lithium inventory levels?

Amidst conflicting reports of lithium inventory levels, Benchmark’s latest Monthly Lithium Inventory China shows that chemicals inventory across carbonate and hydroxide fell a further 2.8% m-o-m in August. This continues the trend seen so far in 2026 where inventory levels have fallen 10.0% year-to-date and the typical H1 build and H2 drawdown pattern has been absent. “It leaves the market without the buffer between supply and demand that dampens price movements as participants near the final quarter of the year, where consumption is typically strongest,” said Adam Megginson, Benchmark’s principal lithium price analyst.
