Copper Backwardation Deepens as LME Cancelled Warrants Climb

SHFE copper's November-December spread widened to 690 yuan per tonne, a 0.63% backwardation, keeping near-term metal at a premium (China domestic curve, as of 2026-10-21). The front month held at 2611 with no roll, so the squeeze signal stays clean for anyone funding physical positions. LME copper cancelled warrants reached 83,750 tonnes against opening stock of 232,175 tonnes, a 36.07% cancellation ratio (LME warrant data, as of 2026-10-20). That is a heavy share of warehouse metal already earmarked for removal, which tightens available LME inventory. Watch whether the Yangshan premium holds as import demand tests both curves.

Lithium Carbonate Curve Shows Extreme Near-Term Premium

GFEX lithium carbonate's October-November spread blew out to 12,160 yuan per tonne, a 12.21% backwardation, the steepest structure on the board (China domestic curve, as of 2026-10-21). The main contract sits at 2701, so the tightness is concentrated in the expiring months rather than the benchmark. The daytime main contract fell 4.71%, making lithium carbonate one of the session's top decliners (SMM_CN, 2026-10-21). That combination of a collapsing benchmark and a screaming front spread points to acute delivery-month stress. Traders running calendar spreads should treat the roll risk as elevated.

Nickel Leads Base Metals While Lead Drifts Sideways

SHFE nickel gained 3.05% to lead the base metals complex, with tin up 1.77%, while SHFE lead slipped 0.4% as the only decliner (SMM_CN, 2026-10-21). The lead 2612 contract moved sideways in a long-short deadlock, per SMM's brief comment (SMM_EN, 2026-10-21). LME lead cancelled warrants stood at 34,875 tonnes on opening stock of 338,125 tonnes, a 10.31% ratio (LME warrant data, as of 2026-10-20). That modest cancellation share suggests no imminent squeeze in LME lead, consistent with the range-bound domestic price action. Nickel's strength contrasts with a quiet lead tape.

Power Demand Mix Shifts Toward Data and EV Charging

China's September total power consumption reached 899.7 billion kWh, up 1.2% year on year, while tertiary industry rose 4.9% (SMM_CN, 2026-10-21). Internet data services jumped 35.4% and EV charging and swap services surged 57.0%, the fastest-growing segments. High-tech and equipment manufacturing consumed 116.7 billion kWh, up 4.6%. Household use fell 6.0% on extreme weather. For metals desks, the demand story is tilting toward copper-intensive grid, data center and charging buildout rather than traditional household load. January-September total consumption rose 3.9% year on year.

Yangshan Copper Premiums Jump on Import Demand

The Yangshan copper warehouse receipt average premium rose 10 to 148, while the bill of lading average premium gained 4 to 135 (Yangshan copper premium, as of 2026-10-21). Both moves point to firmer import appetite at the Shanghai bonded zone, a live gauge of physical demand for arriving cathode. That lines up with the deep SHFE backwardation and the heavy LME cancelled warrant ratio, which together suggest metal is being pulled toward China. Traders funding import arbitrages should note the premium improvement against the still-inverted domestic curve. No basis data was reported for the session (China spot versus main contract, as of 2026-10-21).
