It was learned that the weekly composite operating rate of SMM lead-acid battery enterprises across five provinces was 73.92% from March 20 to March 26, 2026, basically stable WoW. As it was late March, aside from some large lead-acid battery enterprises reporting moderate orders and production line operating rates at full capacity, other small and medium-sized enterprises said that the traditional consumption off-season from April to May was approaching, and producers mainly produced based on sales. At present, the SHFE/LME price ratio for lead remained high, and lead-acid battery costs were higher than those in markets outside China. Coupled with constraints from tariffs, geopolitics, and other factors, orders for export-oriented enterprises in particular were hindered, leaving factory production lines underutilized. If subsequent orders continued to weaken, operating rates would be lowered again.

[SHFE/LME Price Ratio Rebounded and Fluctuated Below 7.5]: This week, the SHFE/LME price ratio rebounded and fluctuated below 7.5, and the zinc ingot import window remained closed. Outside China, geopolitical disruptions were frequent, and market expectations for a swift end to the conflict in the Middle East weakened, but disruptions at ex-China mines supported zinc prices, and LME zinc rebounded from lows.

[Overnight, LME Aluminum and SHFE Aluminum Edged Up Slightly, but Aluminum Prices Faced Short-Term Pressure at High Levels] Continued destocking in LME inventory provided bottom support for LME aluminum, but amid tightening fund liquidity and profit-taking by bulls, upward momentum remained insufficient, and the backwardation structure weakened somewhat. China’s social inventory rose to a high for the same period in nearly five years, and the inventory buildup cycle had yet to end, with high inventory and weak spot fundamentals jointly weighing on upward momentum. The divergence between domestic and overseas drivers continued, the SHFE/LME price ratio kept weakening, and prices were mainly under pressure in the short term.

March 23, 2026: The average warrant price rose by $4/mt from the previous trading day, closed at $52/mt (price range: $44-60/mt); the average B/L price rose by $6/mt from the previous trading day, closed at $53/mt (price range: $45-61/mt); the average price of EQ copper (CIF B/L) rose by $1/mt from the previous trading day, closed at $30/mt (price range: $25-35/mt), with quotes referring to cargoes arriving from late March to mid-April. Intraday, the SHFE/LME price ratio remained elevated, but transactions were relatively weak. Both warrant and B/L offers and deals moved higher, but most spot cargo in the market had already been locked in for price-ratio imports. It was heard that a small volume of pyrometallurgy B/L arriving in late March was offered at $50-60/mt, QP April; EQ B/L arriving in late March and early April was offered at $35, while EQ B/L arriving in mid-to-late April was offered at $35/mt and traded at $30/mt, with QP available in both April and May. General pyrometallurgy warrants deliverable within the week were quoted at $50/mt, QP April.

Next week, there will be limited macroeconomic data releases, mainly including the final March University of Michigan Consumer Sentiment Index for the US and the final March one-year inflation expectations for the US. At present, key events outside China remain the geopolitical issues in the Middle East, as well as the views of representatives from various countries on global trade development at the upcoming 14th WTO Ministerial Conference (MC14). LME lead, markets outside China will continue to be affected by geopolitical issues, with damage to the economic environment and prolonged logistics cycles dragging LME lead lower consecutively to a near one-year low. However, we need to note that the SHFE/LME price ratio widened, allowing more imported lead to flow into the Chinese market, while spot cargo availability in Southeast Asia tightened and spot premiums rose, with LME Cash-3M contango narrowing to -$41.44/mt. Next week, attention should be paid to the possibility of lead prices probing lower and then rebounding after macro headwinds are fully priced in. LME lead is expected to trade at $1,840-1,930/mt next week. SHFE lead, dragged down by the decline in overseas lead prices, the SHFE/LME price ratio widened and expectations for lead ingot imports increased, especially against the backdrop of China’s lead ingot social inventory standing at a 16-month high, sending lead prices lower in succession. At the same time, we need to note that inventory at domestic smelters remained on a declining trend, losses in secondary lead widened, and the inversion between secondary lead and primary lead prices may become a factor stopping lead prices from falling. In addition, downstream enterprises purchased on dips, and attention should be paid to the subsequent decline in social inventory. If destocking materializes, lead prices may stop falling and rebound. The most-traded SHFE lead contract is expected to trade at 16,100-16,750 yuan/mt next week. Spot price forecast: 16,100-16,550 yuan/mt. For primary lead and secondary lead, supply continued to rise as smelters resumed operations after maintenance. On the demand side, downstream enterprises' short-term restocking on dips may facilitate destocking, but from April to May is the traditional off-season for the lead-acid battery market, and the sustainability of downstream enterprise procurement is limited, so spot lead premiums are expected to struggle to continue rising.

[SHFE/LME Price Ratio Rebounded and Fluctuated Around 7.4]: This week, the SHFE/LME price ratio rebounded and fluctuated around 7.4, and the zinc ingot import window remained closed. Outside China, geopolitical disruptions were frequent. After the US Fed kept interest rates unchanged, the market bet on a US Fed rate hike, and LME zinc fell below key levels. Subsequently, bearish factors were gradually digested, and LME zinc rebounded from lows.

[Macro Pressures Combined With High Inventory, SHFE Aluminum Remained Under Pressure at Elevated Levels in the Short Term] Continued destocking in LME inventory provided bottom support for LME aluminum, but amid tightening fund liquidity and profit-taking by bulls, upward momentum was insufficient, and the backwardation structure weakened somewhat. In China, social inventory rose to a high for the same period in nearly five years, and the inventory buildup cycle had not ended. High inventory and weak spot fundamentals jointly weighed on upward momentum. The divergence between domestic and overseas drivers continued, the SHFE/LME price ratio kept weakening, and SHFE aluminum fell below the key threshold of 25,000 yuan/mt, remaining mainly under pressure at elevated levels in the short term.

It was heard that a small volume of pyrometallurgy B/L arriving in late March was quoted at $50-60/mt, QP April; EQ B/L for late March and early April was offered at $35, and EQ B/L arriving in mid-to-late April was quoted at $35/mt, QP May. Ordinary ER copper warrants for delivery within this week were quoted at $50/mt, QP April.

[Geopolitical Tensions Combined With Deferred Interest Rate Cut Expectations Leave SHFE Aluminum Under Short-Term Pressure but Fluctuating at Highs] Against the backdrop of continued tightening LME liquidity, LME aluminum still has upward momentum, with strong support from prices outside China, and is expected to maintain a backwardation structure in the short term. China remains in a phase of high inventory coupled with weak fundamentals, and its upward momentum is significantly weaker than that outside China. Amid divergent domestic and external drivers, the SHFE/LME price ratio is expected to continue weakening, and aluminum prices are still expected to fluctuate at highs in the short term.

[SMM Aluminum Morning Meeting Summary: Geopolitical Premiums Persist, Aluminum Prices Remained Fluctuating at Highs] Against the backdrop of continued tightening LME liquidity, LME aluminum still had upward momentum, with strong support from prices outside China, and was expected to maintain a backwardation structure in the short term. China, meanwhile, was in a phase of high inventory plus weak spot fundamentals, with upward momentum clearly weaker than outside China. Amid divergent domestic and external drivers, the SHFE/LME price ratio was expected to continue weakening, and aluminum prices were expected to remain fluctuating at highs in the short term.
