Expectations of Hormuz Reopening Ease Inflation Concerns, Domestic and Overseas Inventory Mismatch Pushes Up Copper Prices [SMM Macro Weekly Review]

On the macro front, this week copper prices drifted higher overall. Negotiations between the U.S., Iran, and Oman over the Strait of Hormuz made progress, and market expectations for a near-term reopening of the strait heightened. International oil prices pulled back accordingly, easing inflation worries from energy prices. Meanwhile, the U.S. July ADP employment figure came in below market expectations, and the cooling labour market also dampened market expectations for multiple US Fed rate hikes this year. Although some Fed officials still sent hawkish signals and the strait reopening arrangements are not yet fully clear, their pressure on copper prices was relatively limited. Additionally, expectations that the U.S. may impose tariffs on imported copper continued to attract copper cathode flows to the U.S., driving inventory accumulation at COMEX. Meanwhile, LME inventories and deliverable stocks kept declining, creating a clear regional mismatch of exchange inventories. U.S. tariff premiums and tightening supply outside the U.S. combined to push LME copper prices higher. As of 11:00 Beijing time on August 7, 2026, LME copper hit a low of $13,769/mt this week before shooting up to a high of $14,369/mt, up $600/mt from the low, a gain of about 4.36%. The most-traded SHFE copper contract hit a low of 105,140 yuan/mt, then rebounded to 108,470 yuan/mt, up 3,330 yuan/mt from the low, a gain of about 3.17%.

Fundamentals side, as of August 6, SMM copper inventories across major regions in China increased by 7,300 mt WoW to 119,200 mt, extending the accumulation trend. On the supply side, arrivals of both domestic copper and imported copper cathode increased recently, with imported materials such as Peruvian large plates, ESOX, and Myanmar copper gradually circulating in the market. Combined with higher copper prices boosting suppliers’ willingness to sell, spot supply that was previously tight gradually eased. On the demand side, end-user orders were generally weak amid the traditional consumption off-season, and high copper prices further suppressed downstream purchase willingness. Market transactions were sluggish, and purchases remained mainly need-based. However, hi-quality copper and registered SX-EW copper supplies were relatively limited, and transactions improved for some low-priced cargoes, still providing some support to spot premiums.

Looking ahead to next week, the market will continue to watch whether the U.S.-Iran deal materializes, the Strait of Hormuz reopening arrangements, and Fed officials’ comments on the future rate path. If expectations for the strait's reopening persist, oil prices and inflation worries will cool further, and together with a slowing U.S. labour market, macro sentiment may still support copper prices. Should negotiations falter again, geopolitical risks and energy price fluctuations could increase volatility in the futures market. In addition, watch out for a resurgence of resource protectionist policies outside China, which could further disrupt global copper flows. Fundamentals side, increasing domestic and imported copper supply will continue to ease domestic spot supply tightness, but high copper prices, inventory accumulation, and the off-season will limit downstream restocking, and SHFE copper spot premiums still face downward pressure. Next week, copper prices are expected to consolidate at highs with an upward bias, with LME copper likely to outperform SHFE copper, but SHFE copper’s upside room will still be constrained by weak domestic demand.
