Shanghai Metals Market now expects lithium's next supply deficit in 2030, not sooner, as a sulphuric-acid cost shock and split ASX broker ratings on Pilbara Minerals, IGO Limited and Core Lithium reshape the outlook.
Analysis 78% confidence
For much of 2025 and early 2026, the dominant lithium narrative was straightforward: a structural supply deficit was coming, and coming soon. Morgan Stanley had penciled in an 80,000-tonne lithium-carbonate-equivalent deficit for 2026 alone, and UBS, while more conservative, still saw a 22,000-tonne shortfall versus a 61,000-tonne surplus the year before. SMM's latest call complicates that story rather than reversing it. The firm still expects a deficit — just not until 2030, with the market swinging back through a period of rough balance across 2027 and 2029 first. That three-year stretch matters because lithium equities have historically priced in supply tightness well before a physical shortage shows up in inventories, and a market that believes balance can persist for several more years tends to mark down growth and development-stage names faster than established, low-cost producers.
The mechanism behind the delay is supply discipline meeting a genuine cost shock. SMM's model assumes lithium supply keeps growing around 30% across 2026 and 2027 — enough, in its view, to outpace even accelerating demand from grid-scale battery storage, which it expects to climb roughly 23% a year through 2030. At the same time, actually turning spodumene rock into battery-grade lithium has become considerably more expensive. Sulphuric acid is the workhorse reagent in that conversion — Benchmark Mineral Intelligence puts the requirement at roughly 1.35 tonnes of acid for every tonne of lithium carbonate produced — and its price has risen from about $50 a tonne in 2020 to more than $500 a tonne this year, after the partial closure of the Strait of Hormuz and damage to Russian gas infrastructure removed roughly half of the world's traded sulphur supply. That single input now adds an estimated $550 a tonne to cash costs, a floor under lithium prices even as the deficit timeline itself moves further out.
Demand composition is shifting underneath both stories. Roughly four in five batteries made today use lithium iron phosphate (LFP) cathodes, which are themselves close to three-quarters phosphoric acid by weight — meaning the same kind of sulphur-linked cost pressure is also pushing up phosphate input prices, which BMI says have risen 85% since March 2026. Longer term, UBS now expects sodium-ion batteries, which use no lithium at all, to take a larger share of the market: up to 3.4% by 2030 and 14% by 2035, cutting nearly 10 percentage points off LFP's projected 2035 share. UBS says the cost gap between sodium-ion and LFP cells has already narrowed from around $28 a kilowatt-hour to $7-11, and could close entirely by 2027 if lithium carbonate prices stay in the $21-29-a-kilogram range — a band that overlaps with where prices are trading today.
That split outlook is showing up directly in how brokers rate ASX-listed lithium producers. Mineral Resources carries a consensus Buy rating with roughly 5.2% target upside, reflecting its diversified iron-ore and lithium earnings base. Pilbara Minerals, the sector's most closely watched pure-play spodumene producer, has drawn recent downgrades from Morgans and Ord Minnett to a Strong Hold. IGO Limited — which holds a 24.99% stake in the Greenbushes mine, the highest-grade hard-rock lithium deposit in the world, but wrote down its Kwinana lithium-hydroxide refinery in 2025 — has been cut to Neutral by both JPMorgan and UBS. Core Lithium, which suspended mining at its Finniss project in the Northern Territory amid weak prices, carries the sector's largest consensus downside among stocks with meaningful broker coverage. Across the wider ASX lithium cohort, brokers remain net-positive — seven consensus Buy ratings against three consensus Holds among stocks with at least three analysts covering them in the past three months — but the specific downgrades at IGO Limited and Pilbara Minerals show a later deficit timeline is already being priced into individual names, not just the sector average.
Why This Matters 68% confidence
A lithium deficit timeline pushed out to 2030 matters well beyond Australia's mining sector. Battery costs feed directly into electric-vehicle and grid-storage economics worldwide, including in India, where domestic EV and battery-manufacturing plans depend partly on how cheaply and predictably lithium chemicals can be sourced. A market that stays roughly balanced through 2027-29, as SMM now expects, would give battery and EV makers more room to plan around stable input costs — but the sulphuric-acid cost shock described above means balanced does not necessarily mean cheap. For Indian investors and procurement teams tracking global commodity costs, the split now opening up between ASX lithium producers — cost-advantaged, diversified names like Mineral Resources holding up better than higher-cost, refinery-dependent operators like IGO Limited — is an early look at how the next phase of the lithium cycle may separate winners from laggards well before any physical shortage shows up in inventories.
Price Impact
The story cuts both ways: SMM's push-out of the deficit to 2030 and a projected 2027-29 balance argue against a near-term bullish breakout, while the sulphuric-acid cost shock, tight Chinese inventories and still-growing grid-storage demand argue against a clean bearish read either. ASX broker consensus reflects that split — net-positive sector-wide (seven Buys versus three Holds) but with specific downgrades at IGO Limited and Pilbara Minerals.

Fundamental Analysis
Demand Drivers 75% confidence
Grid-scale battery energy storage is the swing factor in SMM's model — the firm expects it to grow from about 25% to 40% of total lithium-ion battery demand by 2030, even as electric-vehicle unit-sales growth slows to roughly 10% a year through the same period. That EV slowdown is already visible in China: Benchmark Mineral Intelligence reports Chinese EV retail sales down 12% over the first seven months of 2026, alongside dealer inventory swollen to about 1.2 million units versus a typical 160,000.
Supply Drivers 72% confidence
SMM's central case for pushing the deficit out to 2030 rests on lithium supply growing roughly 30% across 2026 and 2027 — fast enough, in its view, to keep the market in rough balance through 2029 despite rising storage demand.
Inventory Drivers 74% confidence
Chinese lithium-carbonate inventories sit at about 22 days of consumption, below the roughly 30-day historical average, while cathode-material stocks across China have fallen to 1.7 weeks of consumption, according to Benchmark Mineral Intelligence — tight enough to support near-term prices even with the deficit itself pushed further out.
Geopolitical Risks 80% confidence
The partial closure of the Strait of Hormuz, following US and Israeli strikes on Iran in late February 2026, and damage to Russian gas facilities removed roughly half of the world's traded sulphur supply. That drove the sulphuric acid used to convert spodumene into battery-grade lithium from about $50 a tonne in 2020 to more than $500 a tonne in 2026 — a geopolitical supply shock raising lithium-conversion costs independent of the underlying deficit timeline.
Mining Production 74% confidence
Core Lithium has suspended mining at its Finniss project in the Northern Territory amid weak prices, while IGO Limited's 24.99%-owned Greenbushes mine — the world's highest-grade hard-rock lithium deposit — continues operating with an extended mine life, underscoring the gap in cost position between the sector's lowest- and highest-cost ASX-listed producers.
Refinery Output 76% confidence
IGO Limited wrote down its Kwinana lithium-hydroxide refinery in 2025 after it failed to reach nameplate production capacity, a factor cited alongside JPMorgan's and UBS's recent downgrades of the stock to Neutral.
Country Impact 70% confidence
| Country | Impact | Reason |
|---|---|---|
| Australia | High | Home to the ASX-listed lithium producers whose broker ratings are splitting as the deficit timeline moves out, and to the Greenbushes and Pilgangoora mines central to global spodumene supply. — Mineral Resources holds a Buy consensus while IGO Limited and Core Lithium have drawn recent broker downgrades. |
| China | High | The largest lithium-chemical consumer and refiner; Chinese EV sales trends and inventory levels are the demand-side variable behind SMM's 2030 deficit call, and lithium carbonate prices are set in the domestic yuan market. — Chinese EV retail sales fell 12% over the first seven months of 2026 even as dealer inventory swelled to about 1.2 million units. |
Industry Impact 66% confidence
| Industry | Effect | Reason |
|---|---|---|
| Electric Vehicle Manufacturing | Positive | A lithium market that stays roughly balanced through 2027-29 rather than swinging into deficit sooner gives EV makers more predictable battery-input costs, even as China's slowing EV retail sales show demand growth itself has cooled. |
| Energy Storage | Neutral | SMM expects storage to grow from about 25% to 40% of lithium-ion demand by 2030, but as fixed-price buyers, storage developers become price-sensitive at higher lithium carbonate levels, capping how much cost they can absorb. |
| Battery Manufacturing | Negative | Rising sulphuric- and phosphoric-acid costs are pushing up both spodumene conversion costs and LFP cathode production costs, while UBS's improving sodium-ion cost outlook adds a longer-term competitive threat to lithium-based chemistries. |
Timeline
2026-02-28: The Strait of Hormuz effectively closes to commercial shipping after US and Israeli strikes on Iran, disrupting roughly 4 million tonnes a year of seaborne sulphur trade and pushing sulphuric acid costs sharply higher.
2026-03-01: Purified phosphoric acid prices begin a rise that reaches 85% by August 2026, according to Benchmark Mineral Intelligence — a related cost pressure on LFP battery cathode production.
2026-08-26: Shanghai Metals Market tells clients the lithium market's next structural deficit is now expected in 2030 rather than sooner, with 2027-29 projected as a period of rough balance.
Market Sentiment
Bullish Factors 73% confidence
- Sulphuric acid costs have risen more than tenfold since 2020, adding an estimated $550 a tonne to lithium conversion cash costs and creating a real price floor regardless of deficit timing.
- Chinese lithium carbonate and cathode inventories are already tight — 22 days of consumption versus a roughly 30-day average, and 1.7 weeks for cathode material.
- Grid-scale battery storage demand is still projected to grow about 23% a year through 2030, rising from roughly 25% to 40% of total lithium-ion demand.
- SMM forecasts Chinese lithium carbonate peaking near 180,000-200,000 yuan a tonne in the second half of 2026.
- ASX brokers remain net-positive on the sector overall, with seven consensus Buy ratings against three consensus Holds among stocks with meaningful coverage.
Bearish Factors 74% confidence
- SMM's central call is that the next structural deficit is now expected in 2030, not 2027, with 2027-29 seen as a period of rough balance — removing a near-term supply-shock catalyst.
- Lithium supply is projected to grow roughly 30% across 2026 and 2027, outpacing near-term demand growth in SMM's model.
- Chinese EV retail sales fell 12% over the first seven months of 2026, with dealer inventory swollen to about 1.2 million units versus a typical 160,000.
- UBS's improving sodium-ion cost trajectory — potential cost parity with LFP cells by 2027 — is a structural long-run demand risk for lithium.
- IGO Limited and Pilbara Minerals have both drawn recent broker downgrades, and Core Lithium carries the sector's largest consensus downside.
Alternative Scenarios 60% confidence
- If sulphuric acid and phosphoric acid costs ease as new supply sources come online, the cost floor currently propping up lithium prices could weaken even before 2030, removing one of the bullish counterweights to SMM's later deficit timing.
- If sodium-ion adoption accelerates faster than UBS's current forecast — particularly in stationary storage, where energy density matters less — lithium demand growth could undershoot even SMM's balanced-market projections for 2027-29.
- A sharper Chinese EV demand slowdown, building on the 12% year-to-date sales decline BMI reports, could push the deficit further out than 2030 if it is not offset by storage demand growth.
Who Benefits, Who Loses
| Party | Stance | Reason |
|---|---|---|
| Low-cost, diversified ASX lithium producers | Bullish | Names like Mineral Resources, which pair lithium exposure with iron-ore and mining-services earnings, are better placed to ride out a longer balanced-market period than single-asset, high-cost producers. |
| Battery and EV manufacturers | Bullish | A market in rough balance through 2027-29 rather than a sooner deficit gives manufacturers more predictable lithium input costs to plan around. |
| High-cost or refinery-dependent lithium producers | Bearish | Core Lithium has already suspended mining at Finniss, and IGO Limited's Kwinana refinery write-down and subsequent broker downgrades show how a delayed deficit and rising conversion costs squeeze operators without low-cost, high-grade ore. |
| Development-stage lithium juniors | Bearish | Equities in this part of the sector tend to price in supply tightness well before it physically arrives, so pushing the deficit timeline out to 2030 removes a catalyst these smaller, pre-production names depend on for re-rating. |
Investor Watchlist 75% confidence
Educational items to monitor — not investment advice.
- SMM's updated lithium supply-demand balance forecasts as 2026 production data comes in
- Sulphuric acid and phosphoric acid price trends, given their direct link to spodumene and LFP conversion costs

Price Risks 68% confidence
- A later deficit timeline could keep lithium prices range-bound through 2027-29 even if sulphuric-acid costs stay elevated, capping upside for producer margins.
- Faster sodium-ion adoption than currently forecast could structurally cap long-run lithium demand growth.
- A sharper Chinese EV demand slowdown, if not offset by grid-storage growth, could delay the deficit even further than 2030.
- An easing of the Strait of Hormuz-related sulphur disruption could remove the cost floor currently supporting lithium prices.
Historical Comparison
2020 vs. 2026: Sulphuric acid, the main reagent for converting spodumene into battery-grade lithium, has risen from about $50 a tonne to more than $500 a tonne — more than a tenfold increase.
2025 vs. 2026: UBS estimated a 61,000-tonne lithium-carbonate surplus in 2025, before projecting the market flipping to an approximate 22,000-tonne shortfall in 2026 — well before SMM's later 2030 timeline for the next structural deficit.
