I. Price Action & Technicals
The domestic main continuous contract closed at 110,180 CNY/t on September 21, up 0.5934%, with volume of 64,115 lots and open interest of 147,928 lots. The pivot P stood at 110,010 CNY, R1 at 110,400 CNY, and S1 at 109,790 CNY. The past 5 trading sessions formed a clear five-consecutive-up-day structure: September 15 closed at 107,030 CNY, down 1.0722% (volume 107,989 lots, open interest 180,075 lots); September 16 closed at 107,740 CNY, up 0.7575%; September 17 closed at 108,500 CNY, up 0.9960%; September 18 closed at 109,620 CNY, up 1.3967% (volume 81,021 lots); September 21 closed at 110,180 CNY, up 0.5934%. Cumulative rebound from the September 15 close is approximately 3,150 CNY, a gain of about 2.94%.
On the moving average system, as of September 21, MA5 was 108,614 CNY and MA20 was 109,034.5 CNY. The close of 110,180 CNY stood above both moving averages simultaneously, and MA5 has crossed above MA20, with short-term moving averages forming the early shape of a bullish alignment. Note, however, that the 20-day high H20 was 112,330 CNY and the 20-day low L20 was 106,650 CNY. The current price sits in the upper-middle portion of the 20-day range, roughly 2,150 CNY from the upper bound and 3,530 CNY from the lower bound, with the range midpoint at about 109,490 CNY; the close is slightly above the midpoint.
On oscillators, the data segment does not directly provide SHFE RSI and MACD readings, so inference must rely on price structure: five consecutive up days with diminishing daily gains (1.3967% → 0.5934%) indicates marginal slowing of upside momentum. If a subsequent breakout above 110,400 CNY (R1) cannot be achieved on expanding volume, there is scope for a pullback after short-term overbought conditions. On ATR, the international contract HG=F had an ATR of 0.1343 (September 21), corresponding to roughly 2% daily volatility, which can serve as a reference for domestic stop-loss width.
Key levels: upside resistance is, in order, R1 at 110,400 CNY, the psychological 111,000 CNY level above the September 18 pivot of 109,540 CNY, and the 20-day high of 112,330 CNY; downside support is, in order, P at 110,010 CNY, MA20 at 109,034.5 CNY, MA5 at 108,614 CNY, S1 at 109,790 CNY, and the 20-day low of 106,650 CNY. A close holding above 110,400 CNY would open room for a test of 112,330 CNY; a loss of 109,034.5 CNY would put the five-consecutive-up-day structure at risk of breaking down, raising the probability of a pullback to 108,614 CNY.
II. Fundamental Drivers
On macro rates and the dollar, the US 10-year Treasury yield (^TNX) was 4.9630 on September 21, down 0.70%, still in a high range; the US Dollar Index (DX-Y.NYB) was 100.4250, up 0.20%. Elevated rates weigh on the valuation of non-yielding assets, but the dollar index oscillating around 100 rather than strengthening one-directionally creates a neutral-to-bullish marginal environment for dollar-denominated copper prices. If the 10-year yield falls back below 4.9% and the dollar breaks below 100, the financial-attribute support for copper strengthens; if the dollar breaks above 101, upside room is constrained.
The inventory dimension is currently the most core bullish argument. SHFE warrants stood at 22,308 t on September 21, a weekly change of -4,347 t; on September 18 they were 26,655 t, a weekly change of -4,745 t, confirming a clear consecutive destocking trend. On the international comparison, LME warehouse inventory was 255,100 t on September 18, and COMEX registered inventory was 432,092.22 t on September 17, at elevated levels. The domestic headline “COMEX copper inventory retreats from historic highs” (SMM_CN, 2026-09-21 08:40) and the international headline “Copper prices bounce as US runs out of warehouse space” (Mining_Copper, 2026-09-21 18:03:58) corroborate each other, showing tight US warehouse space coexisting with high inventory levels, constituting a regional squeeze theme.
On the term structure, the international CONTANGO structure showed M1-M2 at -0.0360 (-0.5347%), RY at -6.4166%, and slope at 0.0268. The near month trades at a discount to the deferred month, reflecting that the spot end is not tight, which diverges somewhat from domestic warrant destocking; watch for volatility from internal-external spread convergence.
On geopolitical and industrial events, international headlines over the past 48h centered on mining capital operations: Fortune Minerals obtained water and land-use permits for the NICO mine, Artemis acquired Vista for USD 427 million, Capstone Copper sold a Mexican mine for up to USD 385 million, and Silverco's La Negra project was valued at USD 329 million, indicating active upstream M&A that does not alter the near-term supply curve. Among domestic headlines, “Lithium Carbonate Quarterly Report: Demand decelerating, valuation reverting” and “Peak-season demand materializing + policy support! Will steel prices keep rising?” reflect divergent sentiment between ferrous and new-energy metals, with a neutral cross-commodity sentiment spillover to copper.
III. Positioning & Capital Flows
On the international COT positioning, as of September 15 total open interest OI was 289,463 lots, long positions L at 83,704 lots, short positions S at 18,598 lots, net long net at 65,106 lots, with a weekly change Δ of -17,048 lots, the largest single-week reduction in four weeks. Comparing with net long of 82,154 lots on September 8 (Δ +9,272), 72,882 lots on September 1 (Δ -3,389), and 76,271 lots on August 25 (Δ -2,377), net long positioning has declined continuously after peaking on September 8, with clear signs of long profit-taking.
On crowding indicators, as of September 15 netPct was 22.4920%, crowd at 63.36, CTA at 98.00, and hedge at 58.2658%; versus netPct 27.6156% and crowd 69.39 on September 8, netPct 25.7862% and crowd 68.96 on September 1, and netPct 26.9224% and crowd 69.26 on August 25. The net long share and crowding have declined in tandem, indicating that the previously crowded trade is being cleared out. This both reduces stampede risk and implies a lack of incremental long fuel in the near term.
On domestic positioning, SHFE main continuous open interest fell from 180,075 lots on September 15 to 147,928 lots on September 21, a cumulative decline of 32,147 lots over five trading sessions, or about 17.9%, forming a “price up, open interest down” combination with the price advance. This suggests the current rebound is driven more by short covering and short-term capital than by trend-following open interest build. If open interest subsequently stops falling and rebounds alongside a close holding above 110,400 CNY, the quality of the rebound improves; if open interest continues to slide, the sustainability of the upside is questionable.
On options and volatility, ^VIX was 14.8700 on September 21, up 0.41%, at a low level, with overall market risk appetite stable; HG=F chPos was 89.80%, indicating an elevated positioning percentile on the international contract. The data segment does not provide copper option implied volatility; related readings are pending update.
IV. Cross-Asset Relative Value
On the copper-gold ratio, HG_GC_RATIO was 0.0015, with a 1-year percentile P1Y of 71.83% and a 3-year percentile P3Y of 34.52%. The ratio sits at a mid-to-high level on the 1-year horizon and a mid-to-low level on the 3-year horizon, indicating that with gold as the anchor, copper's relative valuation has been strong over the past year but is not extreme on a three-year cycle. If the copper-gold ratio continues to repair toward the 1-year high, copper still has catch-up room relative to gold; if it falls below the 1-year median, it signals weakening pricing of the industrial attribute.
Gold-silver ratio and oil-gold ratio data are not directly provided in the data segment; related readings are pending update. Reference cross-asset anchors are: US Dollar Index 100.4250 (up 0.20%), 10-year Treasury yield 4.9630 (down 0.70%), VIX 14.8700 (up 0.41%). The dollar and rates both at high levels while VIX is low constitutes a “tight financial conditions + low risk premium” combination, which historically gives a neutral directional signal for copper, with direction depending more on inventories and microstructure.
On the cross-tenor relative value implied by the term structure, CONTANGO M1-M2 was -0.0360 (-0.5347%) and RY was -6.4166%. The deferred-month premium structure does not give a near-end tightness signal, diverging internally and externally from domestic warrant destocking. If domestic destocking continues while the international market maintains contango, the internal-external reverse arbitrage logic persists, but watch for FX and tariff disruptions.
V. Sentiment
On the sentiment score, the data segment does not provide quantitative sentiment indicators, so only a qualitative judgment based on headline bias is possible. Over the past 48h there were 4 domestic headlines, among which “COMEX copper inventory retreats from historic highs” is directly bullish copper, “Peak-season demand materializing + policy support! Will steel prices keep rising?” is bullish ferrous sentiment, “Lithium Carbonate Quarterly Report: Demand decelerating, valuation reverting” is bearish new-energy metals, and “GFEX platinum and palladium industrial enterprise risk management training course opens” is neutral. There were 8 international headlines, mainly mining M&A and project permits, among which “Copper prices bounce as US runs out of warehouse space” is explicitly bullish, while the rest are mostly neutral company-level events. Overall, the headline bias over the past 48h is bullish but limited in strength, lacking a macro-level catalyst.
VI. Historical Statistics
The data segment does not provide SHFE Copper seasonal statistics or a 10-year same-period return series; the relevant quantitative patterns are pending update. The available statistical references are: HG=F 5D return 6.67%, 20D return 2.62% (September 21), indicating that international market short-cycle momentum is stronger than medium-cycle momentum; DD52w at 13.4888%, DD20d at 6.9597%, with the drawdown structure showing medium-term drawdown larger than short-term; Sharpe30 at 0.4762, risk-adjusted return positive but not high; Vol20 at 26.3122%, annualized volatility in the medium-to-high range; VaR95 at -2.9712%, single-day 95% confidence loss reference of approximately 3%. The above indicators can serve as statistical benchmarks for position sizing and stop-loss setting, but historical patterns do not represent the future, and specific seasonal conclusions will be updated after data supplementation.
VII. Long-Short Game Deduction
Bullish arguments: First, SHFE warrants at 22,308 t, down 4,347 t week-on-week, with consecutive destocking and an expanding decline, marginal tightening on the spot side; second, the domestic main contract posted five consecutive bullish candles, closing at 110,180 CNY and standing above MA5 (108,614) and MA20 (109,034.5), with the technical structure turning bullish; third, the international market HG=F closed at 6.6865, up 1.08%, with a 5D gain of 6.67%, external momentum pointing upward; fourth, the dollar index at 100.4250 rose only 0.20%, failing to form one-sided suppression, and the 10-year Treasury yield fell 0.70%, marginally easing financial conditions; fifth, the pullback in COMEX inventories from highs and the “US warehouse space exhausted” theme provide squeeze imagination.
Bearish arguments: First, COT net long at 65,106 lots, down 17,048 lots week-on-week, with crowding falling from 69.39 to 63.36, longs are exiting; second, SHFE open interest fell from 180,075 lots to 147,928 lots, with “price up, open interest down” indicating the rebound lacks incremental capital; third, COMEX registered inventories at 432,092.22 t and LME at 255,100 t, absolute levels remain high, and global visible inventory pressure has not dissipated; fourth, the term structure CONTANGO M1-M2 at -0.0360 and RY at -6.4166%, with no near-end tightness pricing; fifth, the closing price still has 2,150 CNY of space from the 20-day high of 112,330 CNY, and overhead hedging pressure remains to be absorbed.
Short-to-medium-term balance of forces: In the short term (1-5 days), destocking and five consecutive bullish candles momentum prevail, but declining open interest and net long reduction form a hedge, leaning toward strong consolidation; in the medium term (1-3 months), high inventories and high interest rates remain unresolved, and if the dollar breaks above 101 or COT net long falls below 60,000 lots, the rebound may end. The overall judgment is “short-term bullish, medium-term consolidation,” with direction selection depending on the validity of breaks at 110,400 CNY and 109,034.5 CNY.
VIII. Trading Strategies & Risk Management
Strategy One (buy the dip): Entry reference 109,000-109,500 CNY range (close to MA20 at 109,034.5 CNY), stop-loss set below 108,400 CNY (confirmed by a break below MA5 at 108,614 CNY), target one 110,400 CNY (R1), target two 112,330 CNY (20-day high), horizon 1-5 trading days, position size recommended not to exceed 15% of total capital, conviction 7. If price gaps directly above 110,400 CNY without a pullback, abandon this strategy to avoid chasing highs.
Strategy Two (sell the rebound): If price rallies into the 112,000-112,330 CNY range and meets resistance with the same-day close falling back below 110,400 CNY, a light short position may be attempted, entry reference 111,500-112,000 CNY, stop-loss set above 112,500 CNY, target one 109,034.5 CNY (MA20), target two 108,614 CNY (MA5), horizon 1-5 trading days, position size recommended not to exceed 10% of total capital, conviction 5. This strategy is mutually exclusive with Strategy One and must be triggered by actual price action.
Risk management: Single-trade risk exposure controlled within 2% of total capital; reference Vol20 at 26.3122% and VaR95 at -2.9712% to set intraday stop-loss width; if SHFE warrants turn to restocking or COT net long falls below 60,000 lots, reduce long positions; if the dollar index breaks above 101 or the 10-year Treasury yield breaks above 5.0%, reduce overall risk exposure. All strategies must be based on real-time prices and volumes and do not constitute a certainty commitment.
IX. This Week's Data Calendar
Next 7 days to watch: September 23 03:15 France Flash Manufacturing and Services PMI, 03:30 Germany Flash Manufacturing and Services PMI, 04:30 UK Flash Manufacturing and Services PMI; September 29 21:30 China Manufacturing PMI (HIGH). Among the above events, China Manufacturing PMI is the highest priority; if the reading beats expectations, it is bullish for copper demand expectations; if European PMIs weaken, it suppresses risk appetite. There are no other high-priority copper-specific data in the remaining periods, and inventory and COT updates are subject to exchange releases.
