SMM, May 21:

According to SMM statistics, as of May 21, aluminum billet inventory across major consumption regions in China totaled 205,500 mt, down 28,500 mt WoW (Thursday), with destocking accelerating. Warehouse withdrawals totaled 55,700 mt during May 12-18, an increase of 14,200 mt from the previous week. Supply side, warehouse inflows declined notably. On one hand, the impact of earlier production cuts by aluminum billet producers in Xinjiang gradually materialized, with warehouse inflows in Wuxi dropping significantly. On the other hand, production cuts by aluminum billet producers in Guangxi resulted in limited arrivals in South China, and local processing fees recovered slightly. Demand side, performance remained relatively stable. Persistently low processing fees in Wuxi combined with aluminum price pullbacks prompted downstream manufacturers to purchase at lower prices. Aluminum billet consumption continued to recover over the past two weeks, driving destocking. Currently, aluminum billet social inventory destocking, primarily driven by supply-side factors, slightly exceeded expectations. With supply-side conditions maintained and demand stable, aluminum billet inventory is expected to sustain the destocking trend, with inventory next week expected to pull back to below 200,000 mt.

Within the week, aluminum prices first fell then rose, showing an overall fluctuating trend of moving sideways, with processing fees displaying a pattern of "strong in the south, weak in the east." By region, Foshan processing fees were quoted at 350/400 yuan/mt, up 170 yuan/mt WoW; Wuxi was quoted at 180/260 yuan/mt, a rebound of 50/60 yuan/mt WoW; Nanchang was quoted at 190/240 yuan/mt, up 140 yuan/mt WoW. Wuxi had relatively high aluminum billet inventory, and producers had the willingness to recover funds, with the market showing a trend of pushing for lower prices to facilitate shipments. In South China, however, arrivals dropped sharply, and the market saw sentiment to hold prices firm, with processing fees relatively moderate. Within the week, absolute prices of aluminum billets in both Wuxi and South China remained mostly in the range of 24,500-24,600 yuan/mt, with processing fees adjusting in line with fluctuations in aluminum prices. It is expected that as aluminum billet inventory enters a virtuous cycle, market processing fees will gradually recover.

Middle East Crisis Sparks Global Economic Slowdown and Inflation, UN Report Shows

The *World Economic Situation and Prospects as of Mid-2026* report released by the United Nations clearly pointed out that the Middle East crisis has posed a new round of shocks to the global economy, directly leading to a slowdown in global economic growth, a renewed climb in inflationary pressures, and a further intensification of global economic uncertainty. Notably, the impact of this crisis has been highly uneven, with developing countries bearing the brunt of the shocks. As things stand, global economic growth is expected to reach 2.5% in 2026, though this figure has been revised down by 0.2 percentage points from the January forecast.

EU Reaches Provisional Agreement on EU-US Trade Deal with Expiry and Safeguard Clauses

Under this provisional agreement, the tariff concessions granted by the EU on US industrial products, certain agricultural products, and seafood will expire on the originally scheduled date if both sides do not decide to extend them. In addition, the EU plans to establish a "safeguard mechanism": if US goods imports surge sharply and cause serious damage to EU industry or agriculture, the European Commission will have the authority to launch an investigation and suspend the corresponding tariff concessions. Regarding steel and aluminum products, if the US maintains tariffs exceeding 15% on EU steel and aluminum derivative products before the end of 2026, the European Commission will likewise have the authority to suspend certain tariff concessions.

Fed Minutes Signal Shift to Tightening Policy Amid Inflation Concerns, Surprising Markets

The US Fed meeting minutes revealed that many policymakers were inclined to abandon the easing bias, with most participants indicating that if inflation remained persistently above the 2% level, it would be necessary to tighten policy. Only a few officials supported future interest rate cuts, and the hawkish tone of the language far exceeded market expectations. Additionally, according to CME data, the market is now pricing in a 60% probability of the US Fed raising interest rates by 25 basis points before year-end, while expectations for interest rate cuts in 2026 have virtually disappeared.
