Spot lithium carbonate prices fluctuated upward this week, with the price center further rising. The futures market performed strongly, with the most-traded LC2609 contract price range rising from 173,400-184,800 yuan/mt at the beginning of the week to 182,500-189,500 yuan/mt, up about 5% WoW, with open interest increasing significantly and bulls actively entering the market. Market transactions remained sluggish, with the psychological price level gap between upstream and downstream further widening. On the upstream lithium chemical plant side, quotes stayed high, willingness to sell spot orders was low, and the sentiment to hold prices firm was evident. On the downstream material plants side, purchases were mainly just-in-time procurement, with limited acceptance of high prices, and psychological purchase price levels concentrated around 170,000-175,000 yuan/mt, with only a few enterprises with rigid restocking needs willing to accept prices around 180,000 yuan/mt. Overall, market inquiries and transactions were relatively sluggish, presenting a stalemate pattern of "upstream holding prices firm and holding back from selling, downstream waiting and watching." Supply side, bullish and bearish factors were intertwined, with short-term disruptions coexisting with medium-term expectations. Bullish factors: continued disruptions from Jiangxi mine license renewals; Middle East geopolitical fluctuations pushing up diesel import costs, with some Australian mines' Q1 quarterly reports confirming cost increases; political instability in Mali raising market concerns over West African ore supply; spodumene concentrates prices continuing to strengthen, reinforcing the cost-support logic for non-integrated lithium chemical plants. Bearish factors: Zimbabwe Huayou announced successful shipment of lithium sulfate, potentially easing some short-term supply anxiety; April domestic lithium carbonate production pace remained generally stable, with salt lake operations maintaining steady production ramp-up; entering May, although Zimbabwe lithium concentrates exports remained restricted, relevant enterprises' raw material inventory could still ensure normal production for the month, with total May production expected to edge up about 3% MoM. Demand side expectations were positive, but actual boost effects still needed verification. Looking ahead, spot lithium carbonate prices are expected to maintain a relatively strong pattern in the short term. Supply side, the actual execution progress of Zimbabwe export quotas and the timing of Jiangxi mine license renewal shutdowns remain key variables; demand side, focus should be on May new energy auto sales data realization and the pace of LFP plant capacity expansion boosting raw material demand. Against the backdrop of unresolved supply-side constraints, cost support, and demand expectations resonating, lithium carbonate prices are expected to maintain a relatively strong trend in Q2.

In 2025, the global NEV and new-type energy storage markets continued to boom. Chinese lithium battery enterprises, leveraging their technological expertise and scale advantages, continued to dominate the global supply chain.

In-depth Interpretation & Review of Indonesia’s Aluminum Industry Policies Centering on bauxite and extending to the entire aluminum industrial chain, the Indonesian government has rolled out a series of policies focusing on three core dimensions: volume control, pricing mechanisms, and tax rates. These measures aim to gradually improve the regulatory system, standardize industrial development, and accelerate the transformation from raw ore exports to integrated domestic downstream aluminum production. This article sorts out relevant policy details and their impacts in detail as follows: I. Volume Control: Strengthen Quota Management & Full-process Digital Supervision to Achieve Precise Supply Regulation ① Bauxite Quota: RKAB Approval Cycle Adjusted to Enhance Government Regulation Capacity Regulation Capacity Indonesia standardizes the full-process mining and sales of bauxite across all mines via the RKAB (Mining Work Plan and Budget) system. The core policy adjustment focuses on optimizing the approval cycle, mainly based on Permen ESDM No.17/2025 issued by the Ministry of Energy and Mineral Resources (ESDM) on October 3, 2025. New regulations shall be officially implemented starting from 2026: Approval Cycle Revision: The RKAB approval model for all mining enterprises is changed from once every three years to annual application and annual approval. Mines must submit RKAB applications for the next year between October 1 and November 15 each year, with all approvals completed by the end of the year to guarantee orderly production in the subsequent year. Transition & Application Timeline: In Q1 2026, if the new annual RKAB quota is still under review, the original 2026 quota can be adopted temporarily. Quota adjustment applications for the current year shall be submitted by the end of July annually, while the centralized submission window for the next year’s quota is set from October 1 to November 15, forming a dual management model of annual approval plus dynamic adjustment. Scenario Analysis & Policy Impacts Original Three-Year Approval Model: Unable to accurately forecast market demand for the next two years, this model easily triggers supply-demand mismatches and overall oversupply, putting downward pressure on bauxite prices. It also limits flexible government regulation, resulting in significant policy lag as quotas cannot be adjusted timely in response to market changes. New Annual Approval Model: The government gains stronger annual regulatory authority to dynamically adjust total annual quotas based on international bauxite prices, global supply-demand fundamentals and domestic smelting demand, improving price stability. Meanwhile, it strengthens fiscal revenue guarantees and regulatory efficiency through a more transparent and streamlined approval process, reduces rent-seeking behaviors, and advances compliant industrial development. ② SIMBARA System: Full-chain Digital Supervision to Curb Illegal Mineral Trading In accordance with Perpres 94/2025 (Presidential Regulation No.94/2025), the SIMBARA system (Inter-Ministerial Mineral and Coal Information System) officially incorporated bauxite into its regulatory scope in 2025, establishing a full-process digital supervision system covering operations from mines to end users. Through the SIMBARA official portal, the Indonesian government tracks real-time bauxite sales data and monitors the entire transportation chain from mining to downstream processing, including inter-island logistics, with precise linkage to mining quotas. It covers all key links: mining sites, processing, transportation and exports. The implementation of this system not only aligns Indonesian bauxite mining with global industry standards, but also effectively restrains irregular activities such as illegal mining, child labor and environmental damage, promoting green and compliant development of the sector. All bauxite mines are required to submit full-operation documents via the SIMBARA system, including production reports, inventory statements and raw material procurement records, for joint reviews by four core authorities: the Ministry of Energy and Mineral Resources, Ministry of Industry, Ministry of Trade, and Ministry of Transportation. The mechanism realizes data sharing, joint supervision and full traceability. II. Tax Rate: Standardize Billing Rules & Optimize Tax Burden Structure ① Indonesia’s Bauxite Tax Framework: Fixed Fee + Ad Valorem Royalty The country’s bauxite taxation policy adopts a dual structure of fixed administrative fees and floating royalties, clarifying differentiated charging rules for various mining rights. Combined with revisions to the HPM pricing mechanism, the overall tax burden structure has been optimized. Fixed Fee: Paid in a lump sum on an annual basis Core Formula: Fixed Fee = Mining Concession Area × Corresponding Unit Rate Floating Royalty: Charged per sales transaction and highly linked to commodity prices Core Formula: Royalty = Sales Volume × Transaction Price × Applicable Rate Transaction bonuses and premiums shall be included in invoice amounts for unified tax calculation; Pricing benchmark confirmation: If the premium is negative (actual transaction price benchmark price), tax calculation shall adopt HPM plus premium. Calculation Example Assume HPM = USD 44/ton, bauxite indicators: Al₂O₃=49%, Reactive Silica=2%. Actual transaction price: USD 35/ton (Premium = -9 USD/ton), Bonus = USD 1/ton, net transaction price = USD 36/ton. Given the negative premium, royalty is calculated based on HPM: Royalty = 44 USD/ton × 7% (standard bauxite royalty rate) = 3.08 USD/ton. ② Revised HPM Pricing Mechanism Effective April 15, 2026 (Kepmen ESDM No. 144/2026) Core Revisions: Pricing unit adjusted: Dry Metric Ton (DMT) → Wet Metric Ton (WMT) New deduction factor: Reactive Silica (R-SiO₂) New moisture adjustment clause added Regulators require bauxite enterprises to cooperate with inspection institutions and add key indicators including alumina content, reactive silica and moisture content to official Certificate of Analysis (COA). Data updates on the e-PNBP and MVP systems are also mandated to ensure accurate royalty calculation. The revised HPM mechanism lowers benchmark prices and overall royalty costs, reducing comprehensive bauxite mining costs and accelerating mine shipments as well as downstream industrial integration layouts. ③ Optimized HPM Pricing Cycle: Higher Flexibility to Align with Global Markets The pricing cycle has been shortened to reduce policy lag and better reflect LME aluminum price fluctuations. Old Rules (Before March 1, 2025): Monthly single HPM release. The pricing reference window covered the 20th of the month before last to the 19th of the previous month, with a pricing lag of around 45 days, failing to reflect timely international price changes. New Rules (Effective March 1, 2025): Semi-monthly HPM releases on the 1st and 15th of each month. 1st Issue (1st of each month): Calculated by average LME aluminum spot prices from the 5th to the 25th of the prior month (21-day cycle, 5-day lag); 2nd Issue (15th of each month): Calculated by average LME aluminum spot prices from the 26th of the prior month to the 4th of the current month (10-day cycle, 5-day lag). Core Benefits Improved market sensitivity: The shortened cycle enables HPM to reflect real-time LME movements, strengthens linkage with global pricing, and avoids price distortion caused by long-term average calculations; Optimized revenue management: The government can adjust domestic mineral benchmark prices more precisely in response to global aluminum volatility, balancing reasonable profit margins for mining enterprises and stable national tax revenue. III. Pricing Policy: Abolish HPM Floor Price to Boost Market Circulation & Downstream Development A landmark adjustment in Indonesia’s bauxite price regulation is the cancellation of the mandatory HPM minimum settlement price, implemented in phases to balance fiscal revenue and market vitality. Old Regulation (Kepmen ESDM No.72/2025): Bauxite transaction prices were strictly prohibited from falling below HPM. This rule triggered supply-demand imbalance, sluggish ore sales and suspended shipments by major miners, severely restricting normal market circulation. New Regulation (Kepmen ESDM No.268/2025): Signed on August 8, 2025, and officially implemented in late August 2025. The core revision abolishes the HPM floor price and allows transactions below benchmark prices. Nevertheless, taxes and royalties are still calculated based on standard HPM values to shield national fiscal revenue from price declines. Core Advantages of the Revised Policy Government Perspective: HPM-based tax collection guarantees stable fiscal revenue independent of market fluctuations. Loosened price controls revitalize trading activity, resolve the supply glut dilemma, support mine capacity expansion and local employment, and secure long-term industrial stability. Industrial Perspective: Discounted transactions ease inventory pressure for miners and accelerate capital turnover. Lower raw material procurement costs reduce production expenses for domestic smelters, incentivize downstream capacity commissioning, and help Indonesia achieve its 2040 strategic goal of full aluminum chain integration.

(CCTV News) [PBOC Reverse Repo Operations Recorded a Net Injection of 4 billion yuan on the Day] The PBOC conducted 5 billion yuan of 7-day reverse repo operations today. As 1 billion yuan of 7-day reverse repos matured today, it recorded a net injection of 4 billion yuan on the day. (Jinshi Data) US dollar: As of 15:03, the US dollar index was at 98.14, up 0.09%. Middle East tensions pushed up oil prices and supported the dollar; a plunge in US consumer confidence weighed on the real economy; and Japan’s manufacturing sector was under pressure. Meanwhile, Fed Chairman nominee Warsh was set to face a hearing, and how to balance interest rate cuts and inflation became the market focus. (Jinshi Data) The US Congress will hold the first confirmation hearing for Fed Chairman nominee Warsh on Tuesday local time. Warsh will pledge to lawmakers to maintain strict independence on interest rate matters. According to opening remarks obtained in advance by Politico, Warsh said interest rate decisions must be strictly independent of political considerations, and monetary policy should not become a tool for short-term political objectives; he also stressed that the US Fed’s credibility comes from institutional constraints and policy discipline. Warsh said the central bank should listen to differing views, and politicians expressing opinions on interest rates is not a real threat; rather, it is the US Fed’s own discipline and rigorous approach that sustains its independent status. He emphasized that price stability is the US Fed’s shield and pledged to take full responsibility for it, “making no excuses and shirking no responsibility.”Regarding the continuous expansion of the US Fed's functional boundaries in the post-crisis era, Warsh also issued a warning, arguing that the Fed should not extend its reach into fiscal policy or social policy areas where it lacks statutory authority. The US Senate Banking Committee is scheduled to hold a confirmation hearing for Warsh at 10 PM Beijing time on April 21. In addition, on April 21, according to Zhuifeng Trading Desk, Citi laid out clear bullish reasons for interest rate cuts in its latest research report, arguing that crude oil supply disruptions were only temporary disturbances and that the path to interest rate cuts, though bumpy, was clearly directional; Deutsche Bank, however, poured cold water on such optimism, warning that US Fed policy was already at a neutral position and was expected to maintain current interest rates indefinitely. As the two major investment banks clashed in their views, the upcoming March retail sales data is set to become the key litmus test to break the deadlock. This data will not only reveal the true destructive impact of high oil prices on core consumption but will also directly determine the US Fed's near-term policy path. (Wall Street Insights) On the macro front: Data to be released today include the US March retail sales MoM, US February business inventory MoM, US March pending home sales index MoM, Germany's April ZEW Economic Sentiment Index, UK February three-month ILO unemployment rate, UK March unemployment rate, UK March jobless claims, Switzerland's March trade balance, and the Eurozone April ZEW Economic Sentiment Index. In addition, attention should also be paid to the US Senate Banking Committee's confirmation hearing on Kevin Warsh's nomination as Fed Chairman, and European Central Bank President Lagarde's keynote speech at the 75th anniversary annual reception of the Association of German Banks. Furthermore, China is about to open a new round of refined oil price adjustment window. On the crude oil front: As of 15:03, oil prices in both markets fell together, with WTI down 1.05% and Brent down 0.73%. The market held optimistic expectations that US-Iran negotiations would continue this week. According to information from maritime intelligence firm Tanker Trackers, a tanker belonging to the National Iranian Tanker Company returned to Iran via the relevant maritime blockade line after completing the offloading of approximately 2 million barrels of crude oil in Indonesia. The tanker is currently heading to Kharg Island, Iran's main oil export hub, and is expected to arrive on the 22nd local time. The tanker reportedly departed Iran in late March, heading for the Riau Islands in Indonesia. (CCTV News) According to foreign media reports, gasoline prices in Australia fell for the third consecutive week as government measures eased the upward pressure on gas station prices triggered by the Iran war. According to data from the Australian Institute of Petroleum, in the week ending last Sunday, the national average gasoline price dropped about 5% to A$2.129 per liter (approximately $1.5279), but remained about 18% higher than at the outbreak of the conflict in early March. Diesel prices fell about 3% to A$3.089 per liter. It was reported that Canberra attempted to ease the domestic fuel crisis by sending delegations to communicate with major trading partners, covering oil transportation costs, relaxing diesel standards, cutting fuel taxes, and tapping into reserves. In addition, the government was conducting a publicity campaign aimed at encouraging Australians to reduce driving. Despite being a major energy producer and exporter, Australia still relied on imports from outside China for most of its refined fuel, and its fuel reserves were among the lowest in developed countries, making the country highly vulnerable to disruptions in global energy supply.
