SHFE Copper Holds Steep Backwardation Into Quarter-End

The SHFE copper Oct-Nov spread stood at 800 yuan per ton, with the front month at 110370 and the second month at 109570 (China domestic curve, as of 2026-09-30). That 0.73 percent premium marks a firm backwardation, signaling tight nearby availability rather than a roll-driven artifact. The main month stayed on 2611 with no roll (China domestic curve, as of 2026-09-30). For desk positioning, the curve rewards carrying long nearby exposure, while any flattening would flag easing physical tightness.

PTA Curve Shows Deepest Backwardation Across the Board

CZCE PTA posted the steepest inversion, with the Oct contract at 7010 and Nov at 6654, a spread of 356 yuan per ton (China domestic curve, as of 2026-09-30). That 5.35 percent gap dwarfs the metals and points to acute near-term tightness in the polyester chain. The main month remained 2701 with no roll (China domestic curve, as of 2026-09-30). Traders should watch whether the front premium persists, since a sharp narrowing would suggest supply relief or demand softening into the new quarter.

Lithium Carbonate Backwardation Narrows Versus Metals Peers

GFEX lithium carbonate held a modest backwardation, with Oct at 120040 and Nov at 119520, a spread of 520 yuan per ton (China domestic curve, as of 2026-09-30). The 0.44 percent premium is far thinner than copper or PTA, hinting at a more balanced battery-metals market. The main month stayed on 2701 with no roll (China domestic curve, as of 2026-09-30). For the desk, the flat curve offers little carry incentive and keeps attention on any shift in spot demand signals.

Yangshan Copper Premiums Flat, Signaling Steady Import Demand

Yangshan copper warrant premiums averaged 119.00, unchanged on the day, while bill of lading premiums held at 114.00 (Yangshan copper premium, as of 2026-09-30). The lack of movement suggests import appetite neither strengthened nor faded into quarter-end. Combined with the firm SHFE backwardation (China domestic curve, as of 2026-09-30), the stable premiums point to consistent physical offtake rather than a restocking surge. Traders should treat any sudden premium jump as the first sign of renewed buying interest.

WTI Mean Diff Narrows, Hinting at Slowing Downside Momentum

SunSirs put the WTI crude Oct 2 mean diff at -4.41 USD/bbl, with the M10 at 91.23 and the M20 at 95.64 (Sina_Futures, 2026-10-02). The diff shifted from widening negative to narrowing, indicating downside momentum slowed and a turning point appeared. For energy desks, that rotation matters because it can precede stabilization in crude-linked spreads. Confirmation would require the diff to keep compressing rather than re-widening in coming sessions.

Soybean Meal Mean Diff Also Turns, Echoing the Energy Signal

SunSirs showed the soybean meal Oct 2 mean diff at -8.20 CNY/t, with M10 at 3398.80 and M20 at 3407.00 (Sina_Futures, 2026-10-02). Like WTI, the diff moved from widening negative to narrowing, suggesting downside momentum slowed and a turning point appeared. The parallel shift across energy and agri markets points to a broader easing of selling pressure. Desks should watch whether the narrowing extends, since a reversal back to widening would negate the signal.
