I. Bottom Line & Directional Bias
Directional call: Bullish.
Three core reasons: First, China's visible inventories are accelerating their drawdown. SHFE Copper warehouse warrants stood at 10,732 t (2026-09-29), down 2,693 t (-20.1%) in a single day, with a cumulative decline of 11,576 t over 5 periods; spot at 111,031.7 CNY against the main contract cu2611 settlement of 109,570 CNY gives a basis of +1,461.7 CNY (1.32%), which, although narrowed by 408.3 CNY from the prior reading of +1,870.0, remains at a premium, indicating near-dated spot tightness. Second, the price structure has not broken down. The settlement price of 109,300 CNY (2026-09-29) sits at the 51.4% midpoint of the 20-day channel of 106,650–112,330, with 5-day -0.55% and 20-day +0.43%, while ATR14 of 1,304.3 CNY (1.19%) indicates volatility compression, consistent with range-bound digestion rather than a trend reversal. Third, the international vs China market value spread is repairing. China's tax-adjusted premium to LME stands at +0.28% (2026-09-29), a clear recovery from -0.72% 5 days earlier, with import losses narrowing, as the weakness in the international market HG=F at 5-day -3.18% has not fully transmitted to the China market.
Conditions that would invalidate the directional call: A settlement price effectively breaking below the lower bound of the 20-day channel at 106,650 CNY; or SHFE warehouse warrants turning to sustained accumulation and the spot basis flipping to a discount. If either occurs, the bullish thesis is void.
II. Price Action & Technicals
Settlement basis: SHFE.CU SHFE Copper settled at 109,300 CNY on 2026-09-29, closing at 109,570 CNY, +0.13% versus the prior settlement; 5-day -0.55%, 20-day +0.43%. ATR14 is 1,304.3 CNY (1.19% of price, full daily range), RV20 is 15.8%. The 20-day channel is 106,650–112,330, with the current price at the 51.4% level, i.e. mid-channel. Pivot P 109,450, R1 109,930, S1 109,090; the current price is about 630 CNY from R1 and about 480 CNY from S1, both less than half an ATR14 (approximately 652 CNY), so R1/S1 are not used as trading levels.
Last 5 settlement daily bars: 09-22 closed 111,320; 09-23 closed 110,330; 09-24 closed 110,130; 09-28 closed 109,440; 09-29 closed 109,570. The sequence shows that after pulling back from the 09-22 high of 111,770, the market touched a low of 108,970 on 09-28 and stabilized with a modest rebound on 09-29, finding short-term support near 109,000.
Weekly basis: The last completed weekly bar was 2026-09-21 to 2026-09-24, opening at 109,840, high 111,770, low 109,620, close 110,130, a weekly change of +0.47%, a small bullish candle. This week (2 trading days from 2026-09-28) has not yet closed, currently quoted at 109,570 (-0.51%), and no weekly conclusion is drawn on this basis.
Night session basis: The 09-29 21:05 to 09-30 01:00 night session opened at 109,280, high 109,790, low 109,280, close 109,430, -0.13% versus the day session close and +0.12% versus settlement; the night session was narrowly range-bound and did not break out of the day session range.
International market comparison: HG=F settled at 6.62 (2026-09-29), 1-day -0.23%, 5-day -3.18%, 20-day -1.03%; ATR14 0.15 (2.27%), RV20 26.7%, 20-day range 6.35–6.93, position 46.9%. International market volatility is significantly higher than the China market (RV20 26.7% vs 15.8%), and the 5-day decline is larger, with the China market relatively resilient.
III. Supply-Demand Balance & Fundamental Drivers
Inventory side: SHFE Copper warehouse warrants 10,732 t (2026-09-29), daily change -2,693 t (-20.1%), cumulative -11,576 t over 5 periods, with the drawdown pace accelerating. LME copper inventories 251,350 t (2026-09-28), daily change -150 t (-0.1%), but cumulative +17,075 t over 20 periods, with the international market still in an accumulation channel. COMEX copper registered inventories 431,366 t (2026-09-25), daily change -1,451 t (-0.3%). The three major exchanges show divergent inventory trends: China is accelerating destocking, the international market is slowly accumulating, and the change in total global visible inventories is limited.
Basis side: Spot at 111,031.7 CNY against the main contract cu2611 settlement of 109,570 CNY gives a basis of +1,461.7 CNY (1.32%), a spot premium; the prior reading was +1,870.0 CNY, a change of -408.3 CNY, with the premium narrowing but still positive. The premium structure supports near-month prices, but the narrowing magnitude signals a marginal easing in spot tightness.
Supply side: International headlines show that China's refined copper output growth is expected to slow sharply in 2026 due to raw material constraints (SMM_EN, 2026-09-29); workers at the Centinela copper mine approved a strike, with labor negotiations entering mediation (SMM_EN, 2026-09-29). Mine-side disruptions and smelting raw material tightness provide potential support for copper prices.
Macro transmission: The US dollar index at 101.38 (2026-09-29), up 0.17% on the day; the US 10-year Treasury yield at 5.255, up 0.29% on the day. The dollar and rates strengthening in tandem weighs on dollar-denominated copper, but the China market is dominated by RMB denomination and China fundamentals, so transmission is limited. China's September official manufacturing PMI is expected at 50.1 (prior 49.8) and non-manufacturing PMI expected at 49.2 (prior 49.0); if the data beat expectations, it would improve the demand outlook for base metals.
IV. Positioning & Fund Flows
China seats: Top 20 seats hold 361,856 lots long (daily change -1,507) and 375,685 lots short (daily change +2,879), net short -13,829 lots (daily change -4,386). Longs decreased and shorts increased, with the net short widening, indicating that China's major seats are adding short-term bearish positioning.
Main contract: SHFE.CU main contract notional open interest 101.47 billion CNY, daily change -0.014 billion CNY (open interest -26 lots, price change +0.13%), showing a decline in open interest alongside a price rise, characteristic of short covering rather than proactive long accumulation.
International COT: As of 2026-09-22, non-commercial longs 96,421 lots, shorts 13,899 lots, net long 82,522 lots, weekly change +17,416 lots; total open interest 301,657 lots. The sharp increase in net long diverges from the 5-day -3.18% price decline over the same period, indicating that international speculative funds added on dips during the price correction. On crowding, netPct 27.36%, crowd 69.05, CTA 98, hedge 56.61%, with CTA positioning at an extremely high level, warranting caution over pullback risk from crowded trades.
Volatility: China RV20 15.8%, international market RV20 26.7%. On implied volatility, ^OVX 53.74 (1Y percentile 56%), ^GVZ 24.37 (1Y percentile 31%), ^VIX 16.04 (1Y percentile 28%); copper's own IV is not directly given, but related instrument IV percentiles are neutral to low, and option implied volatility is not significantly above realized volatility, keeping option hedging costs manageable.
V. Cross-Asset Relative Value and International vs China Markets
International vs China market relative value: SHFE.CU versus LME.CU, after adjusting for China tax rebates, shows a premium of +0.28% (2026-09-29), versus -0.72% 5 days ago. The premium has swung from negative to positive, import losses have narrowed, and the import window is tilting toward opening. This ratio excludes freight and premium/discount and serves only as a proxy for import P&L.
Copper-gold ratio: HG_GC_RATIO at 0.0016, 1-year percentile 90.08%, 3-year percentile 47.49%. The copper-gold ratio sits at a 1-year high, indicating copper's relative strength versus gold, but the 3-year percentile is neutral, suggesting mid-term valuation is not extreme.
Term structure: International market in CONTANGO, M1-M2 at -0.0455 (-0.69%), RY -8.31%, slope 0.0391. The near end is in contango while the far end is in backwardation, reflecting expectations of relatively loose near-term supply but tighter forward supply.
International market comparison: HG=F settled at 6.62, 20-day range 6.35–6.93, position 46.9%, 52-week range 4.71–6.93. The international market sits at the midpoint of its 20-day range and near its 52-week high; the 5-day -3.18% pullback has not altered the medium-term uptrend structure.
VI. Historical Statistics & Seasonality
Seasonality statistics (20 trading days from the same date over the past 11 years): average +1.75%, median +0.96%, up in 7 of 11 years; best 2011 +8.34%, worst 2013 -2.08%. The sample is limited and serves only as background reference.
From a historical same-period perspective, SHFE Copper from early October to late October has a slightly higher probability of rising than falling, with a median gain of +0.96%, which resonates to some extent with the current low-inventory, high-premium fundamentals. However, note the tail risk of -2.08% in 2013, which cautions that seasonality is not a deterministic rule.
VII. Scenario Analysis
Base case (55% probability): China's low inventory and spot premium support prices, but international inventory build and a stronger dollar cap upside. Triggers: SHFE warrants continue to destock or remain at low levels, spot basis stays at a premium, and prices oscillate within the 20-day channel. Target price: trading in the 109,000–111,000 CNY range, centered at 110,000 CNY. Corresponding action: light long probes at the lower bound of the range, reduce positions at the upper bound.
Bullish case (30% probability): China PMI data beats expectations, compounded by escalating mine-side strike disruptions, SHFE warrants destock further, and spot premiums widen. Triggers: September manufacturing PMI above 50.4, or the Centinela strike materially affecting supply. Target price: a breakout above the 20-day channel upper bound of 112,330 CNY, targeting 113,500 CNY. Corresponding action: add to long positions after a breakout above 112,330 CNY.
Bearish case (15% probability): The dollar index and US Treasury yields continue to strengthen, international inventory build accelerates, China destocking slows, and spot premium turns to discount. Triggers: settlement price breaks below the 20-day channel lower bound of 106,650 CNY, or SHFE warrants build by more than 5,000 tonnes in a single day. Target price: a decline to 105,000 CNY. Corresponding action: stop out long positions on a break below 106,650 CNY, and switch to the sidelines.
VIII. Trading Strategies & Risk Management
Strategy 1 (bullish bias): Entry 109,300–109,600 CNY (near settlement price), stop-loss 107,900 CNY (approximately 1 ATR14, i.e. 1,304.3 CNY, above the 20-day channel lower bound of 106,650 CNY), target 111,500 CNY, horizon 1–5 trading days, position size no more than 15% of total capital.
Strategy 2 (bullish bias, add on breakout): If price effectively breaks above the 20-day channel upper bound of 112,330 CNY, entry 112,400 CNY, stop-loss 111,000 CNY, target 113,500 CNY, horizon 3–10 trading days, position size no more than 10% of total capital.
Risk management: Keep single-trade loss within 1.5% of total capital; if the settlement price breaks below 106,650 CNY, exit all long positions. Watch China PMI on September 30 and US nonfarm payrolls on October 2; consider moderately reducing positions ahead of the data releases.
