[Geopolitical Negotiations Remain Unresolved; Aluminum Prices Continue LME Outperforms SHFE Pattern] Overall, the Middle East negotiation process continued to face setbacks. However, the supply gap outside China and the continued drawdown of LME inventory supported LME prices to hold up well. Meanwhile, China's aluminum ingot inventory remained at elevated levels, and attention should be paid to whether the inflection point of domestic inventory can materialize smoothly.

China's March silver imports hit a record high, as retail investors' buying frenzy and concentrated stockpiling by the PV industry jointly pushed imports far above seasonal averages. Analysts warned that this explosive growth is unlikely to sustain. According to China's customs data, China imported approximately 836 mt of silver in March, nearly triple the past 10-year March average of approximately 306 mt. This import surge was driven by two overlapping demand forces: retail investors purchasing small-sized silver bars as substitutes for high-priced gold, and PV manufacturers rushing to stockpile ahead of the April 1 export tax rebate cancellation. China's silver prices were significantly higher than international benchmark prices driven by robust demand, prompting traders worldwide to ship silver to China for arbitrage, with Hong Kong serving as the primary transit channel. Explosive Imports Unlikely to Sustain However, import momentum already faced multiple cooling factors. Retail side, gold and silver prices retreated from highs set in January. The energy crisis triggered by the Iran war intensified market concerns over inflation, dragging down the performance of zero-yield precious metals, and the momentum of retail bandwagon buying also weakened accordingly. Industrial side, the PV industry consumed approximately one-fifth of global annual supply, with capacity highly concentrated in China. However, this demand pillar was also under pressure, as policy statements signaled curbing overcapacity in the PV industry. Meanwhile, silver prices remained at a relatively high level, potentially prompting the industry to shift toward cheaper base metals as substitutes for silver. Wu Zijie, an analyst at Shenzhen Jinrui Futures, stated that "explosive imports will certainly not continue," and future import flows will return to normal levels. He noted that given China is the world's largest silver producer, there is no basis for long-term imbalance in silver supply and demand.

SMM, April 20: According to data from the General Administration of Customs, domestic primary aluminum imports in March 2026 were approximately 255,000 mt, up 26.5% MoM and up 14.8% YoY. From January to March 2026, domestic cumulative primary aluminum imports totaled approximately 646,000 mt, up 10.6% YoY. Domestic primary aluminum exports in March were approximately 15,000 mt, up 45.9% MoM and up 65.4% YoY. Cumulative primary aluminum exports from January to March totaled approximately 38,000 mt, up around 82.3% YoY. Domestic net primary aluminum imports in March were 240,000 mt, up 25.4% MoM and up 12.7% YoY. Cumulative net primary aluminum imports from January to March were approximately 608,000 mt, up 7.9% YoY. (The above import and export data are based on HS codes 76011090 and 76011010.) Primary aluminum imports by country: In March, 82.3% of total imports came from the Russian Federation, 5.8% from India, 4.7% from Indonesia, and 4.5% from Australia. Primary aluminum imports by trade mode: From January to March, the share of primary aluminum imports under Ordinary Trade was 4.0%, 1.3%, and 1.7% respectively, down 23.6, 27.2, and 21.3 percentage points YoY respectively. LME aluminum outperformed SHFE aluminum in price trends, and the SHFE/LME price ratio declined. Imports under Ordinary Trade decreased, and it cannot be ruled out that a large volume of bonded zone cargoes will be re-exported to other countries outside China going forward. According to SMM, long-term contract imports and some previously signed import orders in March were executed as scheduled. Combined with the arrival of in-transit cargoes, primary aluminum imports stayed high. However, from the current fundamentals perspective, there was a significant primary aluminum deficit outside China, the inflection point for domestic aluminum inventory had not yet arrived, and the loss on primary aluminum imports expanded to a maximum of 852.47 yuan/mt in April. Some imported primary aluminum cargoes are expected to be redirected or re-exported to Japan, South Korea, Thailand, India, and even Europe, the US, and other countries and regions. Overall, domestic net primary aluminum imports in 2026 are expected to decline YoY.
