Copper Backwardation Deepens as LME Cancelled Warrants Climb

SHFE copper's front-month spread widened to 760 yuan per tonne, with the November contract at 109190 against 108430 for December, a 0.7 percent premium (China domestic curve, as of 2026-10-20). That backwardation signals tight nearby availability on the domestic term structure. LME copper cancelled warrants reached 84725.00 tonnes, a 37.58 ratio against opening stock of 225425.00 (LME warrant data, as of 2026-10-19). Desk note: September copper cathode imports fell 16.71 percent year on year, reinforcing the squeeze narrative for anyone running long front-month exposure.

PTA Curve Steepens Into a Sharp Backwardation

CZCE PTA's October-to-November spread jumped to 232 yuan per tonne, the steepest on today's board, with the front month at 6928 versus 6696 (China domestic curve, as of 2026-10-20). That 3.46 percent premium reflects acute near-term tightness in the term structure. Yet the night session told a different story, with PTA declining nearly 3 percent alongside paraxylene down over 3 percent (CLS_Telegram, 2026-10-20 23:01:38). Traders should watch whether the flat-price pullback compresses the spread or whether physical tightness keeps the curve pinned.

Gold and Silver Slip Into Contango as Spot Silver Firms

SHFE gold flipped to contango, with November at 891.78 against 893.02 for December, a negative 1.24 spread (China domestic curve, as of 2026-10-20). Silver mirrored the move, posting a negative 26 spread between 13835 and 13861 (China domestic curve, as of 2026-10-20). The night session saw SHFE gold down 0.51 percent (CLS_Telegram, 2026-10-20 21:00:02). Meanwhile spot silver's intraday gains widened to 1 percent, quoted at $57.65 per ounce (CLS_Telegram, 2026-10-20 22:14:51), a divergence worth flagging for anyone trading the Shanghai-London arbitrage.

Lithium Curve Holds Backwardation Despite Softer September Pricing

GFEX lithium carbonate's October-to-November spread stood at 1360 yuan per tonne, with the front month at 102760 against 101400, a 1.34 percent premium (China domestic curve, as of 2026-10-20). The Lithium Association noted September prices fell at a faster pace while spodumene imports grew and Zimbabwe ore arrived in stages (CLS_Telegram, 2026-10-20 21:17:59). SMM put September spodumene imports at roughly 81300 tonnes LCE, up 7.0 percent month on month (SMM_EN, 2026-10-20 19:03:12). The market is weighing looser forward supply against downstream battery demand that exceeded expectations.

Soybean Meal Contango Widens as Meal Weakens

DCE soybean meal moved deeper into contango, with November at 3233 versus 3286 for December, a negative 53 spread worth negative 1.61 percent (China domestic curve, as of 2026-10-20). The curve signals comfortable nearby supply on the domestic term structure. Night session action showed rapeseed meal down over 1 percent, with caustic soda off 0.75 percent and glass down 0.59 percent (CLS_Telegram, 2026-10-20 21:00:02). For feed-meal spread traders, the widening carry is the cleanest read on near-term meal availability.
