Lithium Carbonate Prices Surge 5%: Real Demand Inflection or Market Hype?

Lithium Carbonate Prices Surge 5% in a Single Day: Is This Resource-Commodity Rally a Signal of Demand Turning Point—or an “Integrated Bottoming” Illusion Driven by Market Sentiment?

On April 18, the front-month lithium carbonate futures contract surged 5.03%—its largest single-day gain in nearly three months. On the same day, the front-month polysilicon futures contract hit its daily trading limit; upstream photovoltaic (PV) leaders—including Tongwei Co., Ltd. and Daqo New Energy—saw their share prices surge toward the daily limit during intraday trading. Fueled by this “dual-chain resonance,” the lithium-ion battery sector erupted collectively: Contemporary Amperex Technology Co. Limited (CATL) hit a new all-time high in share price, while over ten lithium-related stocks—including Shengxin Lithium, Tianqi Lithium, and Ganfeng Lithium—closed at their daily trading limits (Source 10). Market sentiment surged abruptly—yet a sharp contradiction immediately surfaced: In Q1 2024, domestic new-energy vehicle (NEV) sales growth slowed to just 26.2% year-on-year (China Association of Automobile Manufacturers data), and power battery installations declined sequentially for two consecutive quarters. There is no substantive evidence of end-market demand recovery. So does this synchronized rally in upstream resource prices and midstream manufacturing stocks signal a quiet turning point in demand across the NEV supply chain—or is it merely a short-term speculative frenzy, detached from fundamentals and driven solely by expectation-driven positioning and capital rotation?

I. Price Surge Lacks End-Market Support: Q1 Data Reveals a “Weak Reality” Fundamentals

Examining supply and demand dynamics reveals that the current upward momentum in lithium prices lacks robust downstream validation. According to the China Passenger Car Association (CPCA), retail sales of NEV passenger vehicles in Q1 2024 totaled 1.049 million units—a 26.2% year-on-year increase. Although still positive, this growth rate represents a dramatic contraction of nearly 70 percentage points compared with the 93.2% YoY growth recorded in Q1 2023. More critically, power battery installations fell 3.8% month-on-month in January–February 2024; although they rebounded in March, the year-on-year growth was only 17.5%—significantly lower than the sales growth rate. This divergence signals clear inventory pressure across the chain: automakers and battery producers are adopting a “build-to-order” strategy to digest previously accumulated inventory—actual production intensity has not meaningfully improved.

There is also no evidence of meaningful supply-side contraction upstream. Though rumors circulated that some Qinghai salt-lake producers had temporarily halted operations due to cost inversion (unverified by official sources), Baichuan Intelligence data shows domestic lithium carbonate operating rates remained steady at 68.5% in April—up only marginally by 1.2 percentage points from March. Major domestic salt-lake producers—including Lanke Lithium and Zangge Mining—maintained stable operations, with weekly lithium carbonate output unchanged month-on-month. With no systemic production cuts on the supply side—and persistent softness on the demand side—the 5% single-day price jump clearly defies explanation by conventional supply-demand models.

II. The “Dual-Chain Bottoming” Narrative: The Hidden Policy博弈 (Game) Between PV Polysilicon and Lithium Salts

The core driver behind this rally is, in fact, the market’s collective bet on a “policy bottoming” logic. The trigger for polysilicon’s price surge was an unconfirmed rumor about a closed-door production-control meeting held in Chengdu (Source 1). Although involved companies explicitly denied the report (“This is false information”) and spot quotations remained unchanged amid persistently muted trading activity, the rumor’s outsized market reaction exposed deep-seated anxiety: Both the PV and lithium-ion battery sectors—the twin pillars of China’s new-energy industry—are simultaneously confronting severe overcapacity pressures, making coordinated policy intervention urgently necessary. Currently, the industry-wide average cash cost for polysilicon stands at ~¥55/kg, while prevailing spot transaction prices have already dipped below ¥60/kg. Similarly, the spot average price for lithium carbonate hovers near ¥98,000/ton—within striking distance of the full-cost breakeven thresholds for most salt-lake and hard-rock lithium producers. Prolonged pricing pressure would likely trigger widespread, irrational production cuts—threatening employment and local government revenues.

Against this backdrop, the “dual-chain bottoming” narrative has emerged as the most intuitive policy storyline for investors. On one hand, stabilizing polysilicon prices is vital to maintaining overall NEV deployment timelines. On the other, excessively low lithium prices would constrain battery manufacturers’ profit recovery—thereby delaying industrialization of next-generation technologies like solid-state batteries, which have been explicitly designated as a key task in the 14th Five-Year Plan for Scientific and Technological Innovation in the Energy Sector. Hence, capital simultaneously bought into both polysilicon and lithium salts within the same narrow time window—not as a bet on fundamentals, but as an arbitrage on “policy floor thinking”: A concrete bottoming action in either chain would reinforce the upside rationale for the other, generating self-reinforcing positive feedback.

III. Beware of Expectation Bubbles: Cost Anchors for Profit Recovery and Tech Advancement Remain Unmoved

It must be clearly recognized that this price rally has yet to challenge the market’s consensus view on lithium’s long-term outlook. Institutional analysts broadly expect global lithium supply additions in 2024 to reach 120,000 tonnes LCE (Baichuan Intelligence), while demand growth from power batteries alone is projected at ~90,000 tonnes. Even after adding demand from energy storage systems (ESS) and consumer electronics (3C), the annual supply-demand balance remains modestly oversupplied. Unless prices break above and sustainably hold above ¥120,000/ton, the prevailing market consensus—that lithium is stuck in a “bear-market bottoming range”—will remain intact. More crucially, battery makers’ profit recovery does not hinge solely on lithium prices: In Q1 2024, CATL’s gross margin stood at 21.1%, up only 0.3 percentage points year-on-year—largely offset by rising costs for auxiliary materials such as copper foil and electrolytes. Meanwhile, the core bottleneck for solid-state battery commercialization lies in the prohibitively high production cost of sulfide-based solid electrolytes (currently >¥5,000/kg); lithium carbonate accounts for less than 5% of total material costs, rendering lithium price fluctuations virtually irrelevant to its economics.

Moreover, geopolitical risks are quietly reshaping resource pricing logic. Negotiations between the U.S. and Iran in Pakistan (Source 4), coupled with former President Trump’s threat to impose tariffs on Iranian arms exports (Source 3), may not directly involve lithium—but they reinforce the global trend toward regionalized, security-oriented supply chains. China’s external dependence on lithium resources remains above 65%. Policy signals—including accelerated development of Qinghai salt-lake resources and upgraded green mining standards for Sichuan spodumene deposits—are shifting upstream pricing power toward domestic players. This rally may thus represent the first market test of “resource nationalism” logic—anchored not in end-market demand recovery, but in strategic revaluation triggered by geopolitical fragmentation.

IV. Conclusion: Watch for Substantive Breakthroughs Along the “Policy–Price–Profit” Transmission Chain

The concurrent surge in lithium carbonate and polysilicon prices functions as a prism—revealing the growing pains of China’s new-energy industry as it transitions from a high-growth phase into a high-quality development era. With the tailwind of capacity expansion fading, markets are instinctively searching for new pricing anchors: It could be the courage of policy bottoming, the imperative of geopolitical restructuring, or simply a technical rebound after severe overselling. What investors truly need to monitor are not daily 5% moves—but three critical, verifiable signals:
First, whether MIIT or the National Energy Administration issues explicit guidance on upstream capacity regulation for the PV and lithium sectors;
Second, whether lithium carbonate spot prices can sustain an average weekly transaction price within the ¥110,000–¥120,000/ton range for two consecutive weeks;
Third, whether leading battery makers—including CATL and BYD—achieve a sequential gross margin improvement of ≥1 percentage point in Q2 2024.

Only when these three transmission links close into a coherent, self-reinforcing loop can the so-called “demand inflection point” evolve from a sentiment-driven illusion into tangible industrial reality. Until then, every bout of euphoria warrants measured skepticism.
