In H1 2026, SHFE copper cathode spot premiums fluctuated noticeably, exhibiting characteristics of “high volatility, periodical deep discounts, recovery in Q2, and a return to premiums at mid-year.”
Around the Chinese New Year, spot premiums fluctuated more sharply driven by downstream stockpiling, contract rollover, and inventory changes. After the holiday, as social inventory built up seasonally and downstream recovery was slow, the spot market once came under pressure and weakened. After entering Q2, as social inventory continued to destock, particularly the rapid decline in Guangdong, spot premiums in South China rose sharply, opening an arbitrage window for transferring inventory from East China to South China, which indirectly lifted spot premiums in Shanghai. In May-June, although high copper prices and off-season expectations dampened downstream purchases, the COMEX-LME price spread continued to widen. This strengthened the momentum of supplies flowing to the US market from outside China, disrupting the pace of imported copper arrivals in China. The low domestic inventory environment still provided support for spot premiums.
Overall, SHFE copper premiums in H1 2026 were not simply determined by local consumption strength in Shanghai, but were shaped by a combination of low domestic inventory, regional inventory divergence, cross-regional inventory arbitrage, limited imported copper replenishment, and changes in overseas price spreads. Low inventory provided underlying support for the spot market. High premiums in Guangdong were a key driver of the premium recovery in Q2. The widening COMEX-LME spread reduced imported copper’s ability to supplement the domestic market, allowing SHFE copper premiums to show resilience even as consumption weakened at the margin.
1. Review of SHFE Copper Premiums in H1
January: Pre-Holiday Stockpiling and Contract Rollover Disruptions Amplified Premium Volatility
In January 2026, SHFE copper spot premiums were highly volatile. At the beginning of the month, the market was still in the pre-holiday stockpiling window, and some downstream enterprises still had restocking needs before the Chinese New Year. Combined with contract rollover and temporary changes in the supply structure, spot premiums strengthened temporarily. However, as the holiday approached, downstream enterprises gradually shut down, market trading turned thinner, and traders faced increasing pressure to sell. This caused spot premiums to pull back quickly and shift into discounts.
From a market performance perspective, the rapid fluctuations in premiums in January reflected pre-holiday trading pace adjustments and supply-side disruptions rather than sustained improvement in consumption. In the last stage before the Chinese New Year, downstream purchases gradually contracted, market buying decreased, and suppliers actively lowered their offers to facilitate transactions, causing spot discounts to widen. This also laid the groundwork for the seasonal inventory buildup after Chinese New Year and the spot market in Q1 being in the doldrums.
Post-Holiday Inventory Buildup Weighs on Spot; Recovery in Premiums Lacks Sustainability, February-March
After Chinese New Year, China’s social inventory of copper cathode entered a seasonal inventory buildup cycle, while downstream enterprises resumed work at a relatively slow pace, and end-use orders needed time to recover. Against the backdrop of inventory accumulation outpacing consumption recovery, suppliers faced significant shipment pressure, spot market quotations were generally under pressure, and SHFE copper premiums once remained at deep discount levels.
Around mid-February, affected by contract rollover in delivery months, periodic tightening of available cargo, and market sentiment disturbances, premiums briefly surged. However, as downstream consumption had not yet fully recovered at that time and inventory pressure persisted, high spot premiums failed to gain sustained trading support, and quotations subsequently fell back again. This indicated that the periodic surges in the Q1 spot market were more due to short-term supply and futures structure disturbances, rather than a genuine overall strengthening of consumption.
After entering March, as downstream resumption gradually advanced, spot market transactions improved compared with after Chinese New Year, social inventory growth slowed and gradually entered the early stage of destocking, and premiums recovered from the previous deep discounts. Meanwhile, the secondary copper circulation link was affected by invoice, tax compliance, and supply stability issues, driving some secondary copper rod and related consumption to shift to the copper cathode side, and copper cathode substitution demand increased periodically, also accelerating the pace of social inventory destocking. However, as end-use demand recovery remained mild and high copper prices curbed downstream purchases, the market was dominated by just-in-time procurement transactions, and the recovery in premiums was not smooth, falling back multiple times into discount territory after contract rollover.
Overall, the main operating logic for the Shanghai spot copper market in Q1 was ‘post-holiday inventory buildup pressure + slow downstream recovery + contract rollover and delivery disturbances’. Although premiums saw periodic rebounds, they lacked a foundation for sustained rise.
Inventory Destocking Combined with Consumption Improvement; Premium Centers Stagewise Uptick, April-May
After entering Q2, the operating logic of the Shanghai spot copper market showed marginal changes. With the arrival of the traditional peak consumption season, some downstream industries such as wire and cable, copper cathode rod, copper pipe & tube, and copper plate/sheet and strip saw improved operating rates QoQ, and end-use just-in-time procurement showed some recovery. Meanwhile, since Q1, the secondary copper circulation link was affected by factors such as invoice and tax compliance, shifting some demand to the copper cathode side and strengthening the resilience of copper cathode consumption. Demand recovery and substitution consumption jointly drove sustained destocking of social inventory. At the same time, from April to June, domestic smelters entered a period of relatively concentrated annual maintenance, where some smelters underwent periodic maintenance or slowed their shipment pace, resulting in market arrivals falling short of expectations and further tightening available supplies. Driven by both demand recovery MoM and supply-side maintenance disruptions, suppliers strengthened their willingness to hold prices firm, and the center of spot premiums shifted upward.
In addition, continuous destocking in Guangdong and high spot premiums in South China were also important driving forces. In Q2, downstream consumption in South China recovered MoM, coupled with a slow pace of arrivals during the smelter maintenance season, leading to a continuous decline in Guangdong’s social inventory. Available supplies in the region tightened noticeably, strengthening suppliers’ sentiment to hold prices firm, and spot premiums in Guangdong were at one point significantly higher than in Shanghai. Against this backdrop, the price spread between East China and South China gradually widened, creating some arbitrage opportunities for inventory movement. Expectations that some cargoes would flow from East China to South China increased, marginally affecting available supplies in the Shanghai market and indirectly boosting Shanghai spot premiums.
The core driver of the stronger premiums during this period was not entirely a full-blown demand surge but more a reflection of amplified spot price elasticity in a low-inventory environment. On one hand, as social inventory declined, available cargoes for traders and downstream enterprises decreased, and low-priced cargoes were traded quickly. On the other hand, smelter maintenance led to periodic reductions in shipments, and coupled with unstable arrival pace of some imported copper, periodic closures of the import window or widening losses, limited domestic spot replenishment further strengthened suppliers’ willingness to hold prices firm.
Overall, the Shanghai spot copper market in Q2 gradually shifted from Q1’s “inventory pressure dominance” to “destocking logic support.” Specifically, MoM consumption improvement provided demand basis, concentrated smelter maintenance slowed supply replenishment, and rapid destocking in Guangdong amplified regional premium elasticity, together driving a phased upward shift in the center of SHFE copper premiums in April-May.
May-June: High Copper Prices and Off-Season Expectations Suppress Procurement; Premiums Volatility Intensifies
From late May to June, the Shanghai spot copper market entered a stage where bullish and bearish factors intertwined. On one hand, as the traditional consumption off-season approached, the dampening effect of high copper prices on downstream procurement sentiment became more evident. End-users mostly maintained just-in-time procurement, with insufficient willingness to restock proactively, and spot trading activity declined compared with April-May. On the other hand, domestic social inventory remained relatively low, and the impact of concentrated smelter maintenance from April to June had not fully subsided. Arrival replenishment in some regions remained limited, suppliers were reluctant to sell at low prices, and premiums did not experience a sharp unilateral weakening.
During this period, in addition to low domestic inventory and smelter maintenance disruptions, the continuous widening of the COMEX-LME price spread became an important external variable affecting SHFE copper premiums. In May-June, COMEX copper prices were relatively stronger than LME, the COMEX-LME price spread continued to widen, and overseas copper cathode trade flows shifted. Some delivery brand supplies are more inclined to flow to the US market to achieve higher delivery or arbitrage gains, resulting in a squeeze on overseas spot resources available to Asian and Chinese markets.
From the perspective of China's copper imports, the widening COMEX-LME price spread has weakened the incentive for overseas supply to flow into the Chinese market. Even as the domestic SHFE/LME price ratio has periodically recovered, actual arrivals and customs clearance of imported copper have experienced certain lags. For the domestic spot market, this means that against a backdrop of low inventory, imported copper struggles to quickly provide effective replenishment, suppliers' concerns over subsequent concentrated arrivals have eased, and spot quotes still retain some support.
Therefore, the resilience of SHFE copper premiums from May to June cannot be simply attributed to continued strong domestic consumption; rather, it is the combined result of low inventory, smelter maintenance, insufficient import replenishment, and overseas supply diversion. Against a backdrop of weakening downstream procurement, upside room for premiums is limited; however, due to limited domestic supply replenishment and imported copper arrivals falling short of expectations, the spot market is unlikely to quickly shift to surplus, with premiums overall consolidating at highs and experiencing periodic fluctuations.
II. Key Drivers of SHFE Copper Premiums in H1
1. Inventory: Low Inventory Is a Key Support for Spot Premiums
The core support for SHFE copper premiums in H1 came from inventory changes. After Chinese New Year, social inventory accumulated, putting spot premiums under pressure; entering Q2, inventory continued to destock, tightening available market supply and strengthening suppliers' willingness to hold prices firm. In particular, Guangdong's inventory declined rapidly from April to May, driving South China's spot premiums significantly higher and opening up arbitrage opportunities for moving inventory from East China to South China, indirectly boosting the Shanghai market. From this perspective, the premium recovery in Q2 was not driven solely by Shanghai's local consumption but was the combined result of low inventory and regional supply flows.
2. Consumption Recovery Supports Premiums, High Copper Prices and Futures Spreads Limit Sustained Upside
In the traditional peak season of Q2, downstream just-in-time procurement recovered somewhat, supporting the repair of premiums. However, against a backdrop of high copper prices, downstream players had limited willingness to actively restock, with spot transactions mostly based on just-in-time procurement, limiting the room for premiums to rise further. Meanwhile, contract rollovers, deliveries, and changes in SHFE copper futures price spreads also intensified short-term fluctuations. Overall, consumption determines the extent of the premium recovery, futures spreads dictate the short-term pace, and high copper prices cap sustained premium rises.
3. Imports: Changes in Import Profit Margins Affect the Pace of Domestic Spot Replenishment
The pace of imported copper inflows significantly influences SHFE copper spot premiums. When import losses widen and the import window closes, the momentum for overseas supply to flow into China weakens, domestic spot replenishment remains limited, sentiment among suppliers to hold prices firm strengthens, and premiums tend to find support. Conversely, when import losses narrow or even open up periodically, market expectations for increased arrivals of imported copper grow, suppliers become more cautious in quoting, and the upside room for premiums is capped.
From May to June, the LME-COMEX spread kept widening, strengthening the incentive for overseas deliverable supply to flow to the US market and squeezing the availability of import copper resources for Asia and the Chinese market. Meanwhile, although China’s import profit margin recovered intermittently, actual arrivals and customs clearance replenishment lagged, making it difficult for the domestic spot market to shift quickly toward ease. Insufficient import replenishment coupled with a low inventory pattern became a key reason behind the resilience of SHFE copper premiums in the middle of the year.
III. Outlook for SHFE Copper Premiums in H2 2026
Looking ahead to H2, SHFE copper premiums are expected to remain subject to a tug-of-war among inventories, consumption, imports, regional price spreads, and inter-month spread structures. Low inventory will continue to be a critical factor supporting the spot market, but the dampening effect of high copper prices on downstream consumption, changes in the pace of imported copper replenishment, shipment pace of domestic smelters, and the transition between off-seasons and peak seasons will jointly influence the trading range of premiums.
1. Q3: The consumption off-season will cap the upside of premiums, but low inventory may limit the depth of discounts
Q3 is typically a traditional off-season for copper consumption. Weaker orders from some end-users could impact downstream operating rates. Against a backdrop of high and volatile copper prices, downstream enterprises will stay cautious in procurement, with spot transactions expected to be mostly need-based and limited active restocking demand. If the consumption side lacks notable improvement, the upside room for SHFE copper premiums is likely to be capped.
However, from the supply side, if social inventory remains low and imported copper replenishment is limited, it is also difficult for the spot market to see clearly deep discounts. On the one hand, low inventory will continue to support suppliers’ quotes; on the other hand, if the COMEX-LME price spread stays at a relatively high level, overseas supply will continue to diverge toward the US market, the arrival pace of imported copper into China may continue to be affected, and the domestic spot market will struggle to ease quickly.
As a result, SHFE copper premiums in Q3 may present a pattern of “weak demand but limited discounts.” The consumption off-season will restrict the upside of premiums, but low inventory, uncertainty in import replenishment, and tight regional supply could keep the discount room relatively limited. Q3 spot premiums are expected to mostly move sideways within a range, with periodic fluctuations still depending on the inter-month spread structure, inventory changes, and customs clearance pace of imported copper.
2. Q4: Focus on the realization of the peak season and inventory inflection point, premiums may see periodic recovery opportunities
As the market enters Q4, attention will gradually turn to whether the peak consumption season materializes. If power grid investment, home appliance production schedules, new energy, and manufacturing orders show marginal improvement, downstream purchasing sentiment may pick up from Q3, and copper cathode consumption could see phased recovery. Without significant inventory buildup, SHFE copper premiums still have the opportunity to strengthen again.
However, it should be noted that whether Q4 premiums can sustain their uptrend still depends on the pace of supply replenishment. If the import arbitrage window opens periodically, with concentrated arrivals of imported copper, or domestic smelter shipments increase, the tight supply situation in the spot market could ease, limiting the room for premium recovery. Additionally, in H2, attention should be focused on the release pace of new and expanded capacity on the domestic copper cathode supply side. Apart from the Youjin Guanhua project that started production and produced copper cathode in June, projects such as Humon Phase II, Chifeng Jintong Phase II, and Shenghai Phase II will also be sources of supply increment drawing market attention in H2. As these projects gradually come online, ramp up, and achieve stable output, expectations for domestic copper cathode supply replenishment will strengthen progressively.
Meanwhile, if high copper prices continue to curb end-user procurement and downstream restocking fails to pick up significantly, premiums may struggle to form a sustained trend even if they strengthen intermittently.
Therefore, SHFE copper premiums in Q4 are more likely to exhibit phased repair rather than a one-sided increase. The key criteria for judging this are: whether inventories continue to destock, whether downstream orders improve, whether imported copper arrives in concentrated volumes, whether high premiums in Guangdong reappear, and whether the price spread between futures contracts continues to support holding spot prices firm.
Summary
Overall, SHFE copper premiums in H1 2026 showed clear phased characteristics. In Q1, affected by post-holiday inventory buildup and slow downstream resumption, spot premiums came under pressure and fluctuated; in Q2, as destocking progressed, particularly with the rapid decline in Guangdong inventories, high premiums in South China opened arbitrage opportunities for moving copper, boosting premiums across regions; from May to June, although off-season expectations intensified, the widening COMEX-LME price spread diverted overseas supply, and China's imported copper replenishment was limited, so the low domestic inventory pattern continued to support the spot market.
Looking ahead to H2, SHFE copper premiums will continue to be driven by factors including inventory, imports, consumption, and supply increments. In Q3, the seasonal consumption slowdown may cap premium upside, but low inventories, uncertainty over import replenishment, and tight supply in Guangdong could still support spot premiums. In Q4, close attention should be paid to the capacity ramp-up of new and expanded projects. If Humon Phase II, Chifeng Jintong Phase II, Shenghai Phase II, and other projects gradually release output, combined with increased imported copper supplementation, domestic spot supply pressure may rise marginally, and the upside room for premiums will be capped.
Overall, SHFE copper premiums are likely to remain caught in a tug-of-war between "low inventory support" and "supply growth pressure" in H2. If inventory holds low and imported copper supply remains limited, premiums may still see periodic strengthening opportunities; however, if new capacity release proceeds smoothly, the import window opens, and consumption recovery stays weak, spot premiums could gradually come under pressure.
