This week (Aug. 3 – Aug. 7), the weekly average warrant transaction price range for Yangshan copper premiums was $101–$112/mt, QP August, with an average of $106/mt; the weekly average B/L transaction price range was $96–$107/mt, QP September, with an average of $102/mt; and EQ copper CIF B/L prices were $64–$73/mt, QP September, with an average of $69/mt. As of Aug. 7, the ex-exchange rate SHFE/LME copper price ratio for the SHFE copper 2608 contract against LME copper was 1.1247, with an import loss of around 1,385.43 yuan/mt, expanding by about 857 yuan/mt WoW. As of Friday, the backwardation structure for the August LME copper date widened WoW, with the carry spread between the August and September dates at −$61.53/mt. Currently, mainstream offer prices for ER registered copper B/L have dropped to double-digit levels; mainstream warrant offer prices for registered copper were near $100/mt.
This week, Yangshan copper premiums pulled back from high levels, mainly because the SHFE/LME price ratio continued to deteriorate, compounded by the widening backwardation structure of nearby LME contracts, which increased suppliers' willingness to offer cargo. Meanwhile, as copper prices surged, downstream consumption demand was poor. Additionally, high premiums in the domestic market previously attracted cancelled warrants from LME Asian warehouses, which gradually arrived in China, causing temporary congestion at Shanghai Port. Together with some export cargo pressuring prices, market spot premiums weakened.
According to SMM data, China's bonded zone copper inventories as of Thursday this week (Aug. 6) decreased by about 6,000 mt WoW from the previous period (Jul. 30) to 31,100 mt. Specifically, Shanghai bonded inventory decreased by 6,500 mt WoW to 26,900 mt, while Guangdong bonded inventory increased by 500 mt WoW to 4,200 mt. The weekly bonded zone inventory decline was mainly because of reports that cargo ships were heading to the US. Additionally, the slight opening of the export window led to small-scale exports by some smelters to the bonded zone.
Looking ahead, the siphoning effect from North America continues, so the logic of overall supply constraints in the market remains. However, with the SHFE/LME price ratio significantly inverted, consumption demand suppressed by high copper prices, and expectations of concentrated cargo arrivals at ports, traders' psychological price expectations for spot cargo are rapidly declining, and imported copper premiums are expected to see a temporary pullback. Additionally, with the export window slightly open, smelters have export expectations. According to SMM, export volumes in the first week of August up to now have been relatively limited, and future export volumes need continued monitoring.
