Copper Curve Holds Steep Backwardation Into Q4

SHFE copper's front month trades at a premium to the next, with the Oct-Nov spread at CNY/t 800 (China domestic curve, as of 2026-09-30). That backwardation of 0.73% signals tight nearby availability even as the main contract sits on 2611 (China domestic curve, as of 2026-09-30). Headlines note LME three-month copper touched a record USD/t 14875 intraday on September 10, while SHFE's main contract reached a secondary high of CNY/t 112330 (SMM_CN, 2026-10-06). Traders should watch whether mine supply constraints and U.S. import tariff expectations keep the front end bid.

Rebar Contango Deepens as Curve Prices Weakness

SHFE rebar's Oct-Nov spread stands at -CNY/t 58, a contango of -1.87% (China domestic curve, as of 2026-09-30), with the main contract on 2701 (China domestic curve, as of 2026-09-30). The negative spread signals ample nearby supply relative to deferred demand. The main month did not roll (China domestic curve, as of 2026-09-30). This structure contrasts sharply with copper's backwardation, underscoring divergent fundamentals across the industrial complex. Desk attention turns to whether post-holiday construction demand can compress the carry.

PTA Backwardation Hits 5.35% as Front Month Surges

CZCE PTA's Oct-Nov spread is CNY/t 356, a backwardation of 5.35% (China domestic curve, as of 2026-09-30), the steepest curve in the dataset. The main contract remains on 2701 (China domestic curve, as of 2026-09-30). Such a wide front premium points to immediate tightness in the polyester chain. No roll occurred (China domestic curve, as of 2026-09-30). Traders should monitor whether this premium persists or mean-reverts as supply adjusts.

Gold Curve Flat as Spot Slides Below Key Levels

SHFE gold's Oct-Nov spread is -CNY/g 2.24, a mild contango of -0.25% (China domestic curve, as of 2026-09-30), with the main contract on 2612 (China domestic curve, as of 2026-09-30). The near-flat curve reflects a market in transition. Spot gold broke below USD/oz 4110 to a low near USD/oz 4104 (Sina_Futures, 2026-10-06), pressured by elevated U.S. yields and a stronger dollar. Shuibei jewelry sales rose about 20% in early October (Sina_Futures, 2026-10-06).

Silver Tracks Gold's Mild Contango

SHFE silver's Oct-Nov spread is -CNY/kg 32, a contango of -0.21% (China domestic curve, as of 2026-09-30), with the main contract on 2612 (China domestic curve, as of 2026-09-30). The structure mirrors gold's flat curve, suggesting precious metals are moving in tandem rather than diverging on industrial demand. No roll occurred (China domestic curve, as of 2026-09-30). The modest premium offers little carry signal, leaving macro drivers in the driver's seat for now.

Yangshan Copper Premiums Steady at Quarter-End

Yangshan copper warrant premiums averaged USD/t 119.00, unchanged on the day (Yangshan copper premium, as of 2026-09-30), while bill premiums held at USD/t 114.00 (Yangshan copper premium, as of 2026-09-30). The flat readings cap a quarter in which SHFE copper's front month commanded a CNY/t 800 premium over the next (China domestic curve, as of 2026-09-30). Stable import premiums alongside a steep domestic backwardation point to balanced physical flows. Traders should watch whether post-holiday demand reactivates the premium.

Lithium Carbonate Holds Modest Backwardation

GFEX lithium carbonate's Oct-Nov spread is CNY/t 520, a backwardation of 0.44% (China domestic curve, as of 2026-09-30), with the main contract on 2701 (China domestic curve, as of 2026-09-30). The positive spread indicates a modest front-month premium, though far flatter than PTA's 5.35% (China domestic curve, as of 2026-09-30). No roll occurred (China domestic curve, as of 2026-09-30). The structure suggests a market in balance rather than acute tightness, leaving the battery metals complex to trade on broader sentiment.
