Executive Summary: One Metal, Many Prices
Critical-mineral price competitiveness is no longer captured by a single quoted number. A buyer looking at lithium carbonate sees US$19,750/t from Benchmark on 2 September 2026 (CIF Asia, spot) and US$16,158.73/t from SMM’s battery-grade index on 30 September. Both are genuine price-reporting-agency assessments, but they differ in agency, date and delivery basis. This creates the central NMSC framework: critical-mineral price = reference price + delivery basis + policy exposure + origin.
In lithium, USGS puts the 2025 U.S. contract average for battery-grade carbonate at US$9,000/t, and world mine production at about 290,000 t, up 31% from 222,000 t, against consumption of 263,000 t. Prices then climbed through 2026. SMM’s index fell 16.1% in three weeks, from US$19,248.61/t on 8 September to US$16,158.73/t on 30 September, and its front GFEX futures contract, LC2610, was at 119,780 CNY/t on 1 October.
In cobalt, DR Congo accounted for an estimated 73% of 2025 world mine output, and its October 2025 quota of up to 96,600 t of contained cobalt a year for 2026 and 2027 is about 42% of its 2025 mine production (NextMSC calculation). Fastmarkets assessed Rotterdam standard grade at US$23.75–27.15/lb on 2 September, a mid-point of about US$56,108/t, which is 23.9% above SMM’s China domestic price of US$45,278/t on 4 September.
In rare earths, price is increasingly tied to origin. The CREIA index stood at 262.9 on 23 September, and Rare Earth Exchanges reported a recent North American dysprosium oxide transaction at US$3,250/kg and terbium oxide at about US$7,500/kg. Those figures are single transactions and not benchmarks, so they indicate direction, not a market price.
NMSC Insight: Price discovery should be treated as a three-part problem: which benchmark, which delivery point and which origin. A buyer who compares quotes without matching all three can misread the market by more than 20%, as the lithium and cobalt examples above show.
Why This Question Is Live in 2026
The question has shifted from whether critical minerals are expensive to which price a contract should reference. Export policy and agency commentary have made basis differences more visible.
February 2025 — DR Congo suspends cobalt exports
USGS records that DR Congo temporarily banned cobalt exports to address market oversupply and low prices.
2025 — U.S. stockpile solicitation cancelled
USGS reports the United States published a solicitation to buy 7,480 t of cobalt over five years for the National Defense Stockpile and cancelled it before year-end.
October 2025 — Ban replaced by quotas
Export quotas of 18,125 t of contained cobalt were set for the rest of 2025, and up to 96,600 t a year for 2026 and 2027, including 9,600 t for national strategic reserves (USGS).
Second half of 2025 — Lithium prices recover
USGS notes oversupply concerns kept prices low in early 2025, then EV sales growth in China and Europe and battery energy storage demand lifted prices. Spot carbonate (China CIF) rose from about US$9,300/t in January to about US$10,300/t in November.
2 September 2026 — Benchmark and Fastmarkets assessments
Benchmark assessed carbonate at US$19,750/t, hydroxide at US$18,750/t and spodumene at US$2,254/t, noting Chinese domestic prices rose while seaborne markets were mixed. Fastmarkets corrected its Rotterdam cobalt range to US$23.75–27.15/lb after a reporter error.
23 September 2026 — Rare earth price divide
The CREIA index stood at 262.9, and Rare Earth Exchanges reported ex-China dysprosium and terbium transactions at multiples of Chinese reference prices.
30 September – 1 October 2026 — Lithium extends its pullback
SMM’s carbonate index fell to US$16,158.73/t, its hydroxide index to US$14,930.71/t, and its weekly commentary described spot carbonate quotes of 119,000–127,000 CNY/t as a new low for the pullback.
2026 Critical-Mineral Price Index
Prices do not move evenly across the three markets. The blocks below separate primary price-reporting-agency data and government data from supplied secondary observations.

Benchmark’s 2 September commentary points to a split market: Chinese domestic prices rose across grades while seaborne carbonate fell 0.8% on weak buying. By 30 September SMM’s index had fallen further. Read the 2 September print as a start-of-month reference. The 8 September SMM value comes from the supplied dataset and the live page now shows later data.

DR Congo share of 2025 output
USGS records estimated 2025 U.S. cobalt imports of 14,000 t against 10,800 t in 2024, tied partly to uncertainty after the DR Congo export ban. *Rotterdam is 2 Sep and China domestic is 4 Sep, and the sources state different VAT bases, so the gap is indicative.

REEx describes North American dysprosium and terbium transactions as about 15× and 7.5× China reference levels, and notes the DoD floor is a contractual minimum, not a market price.
The Critical-Mineral Price Spectrum
Price levels differ sharply across products, agencies and delivery points. This section sets the three markets side by side using the most recent verified assessments. Lithium and rare earth figures are primary agency data; the cobalt chart mixes a government average, agency assessments and one aggregator observation, and each bar names its source.

Benchmark’s carbonate and hydroxide assessments, taken on 2 September, sit above SMM’s indices taken on 30 September. Because the dates and delivery bases differ, the gap is not a like-for-like fall. Within each agency, the pattern is consistent: carbonate trades above hydroxide at both Benchmark (US$19,750 vs US$18,750) and SMM (US$16,158.73 vs US$14,930.71). Benchmark also notes hydroxide has fewer producers than carbonate, so its assessment reacts more sharply to demand shifts.
The futures curve adds a second signal. On 1 October SMM showed GFEX LC2610 at 119,780 CNY/t and deferred contracts LC2703 and LC2709 at 116,000 CNY/t, about 3.2% below the front month (NextMSC calculation). Futures are not spot prices, but the mild downward slope is consistent with a market that does not expect an immediate rebound.

USGS’s 2025e LME cash average of US$15/lb equals about US$33,069/t. Fastmarkets’ 2 September Rotterdam mid-point is about 1.7 times that level, though the two are different assessments. SMM’s China domestic price of US$45,278/t sits about 24% below Rotterdam.
Rare earths: metals and oxides

Heavy rare earths sit far above light ones: SMM’s terbium metal mid-point of US$1,074.34/kg is about 4.6 times its dysprosium metal price of US$233.55/kg, and dysprosium is about 1.8 times praseodymium metal at US$131.91/kg. SMM also assessed neodymium metal FOB China at US$148–160/kg on 23 September, about 24% above its domestic neodymium metal mid-point of US$124.67/kg on 30 September (NextMSC calculation; dates and bases differ, so treat as indicative).
The 4 Pillars of Critical-Mineral Price Formation
NMSC’s assessment looks past a single quoted price to ask why numbers differ and what a buyer can actually secure. Together, the four pillars separate a headline price from a price that is deliverable, contractable and policy-exposed.
PILLAR 1
Baseline Supply — The Concentration Effect
USGS estimates 2025 world cobalt mine output at 310,000 t, with DR Congo at 230,000 t (74.2%) and Indonesia at 44,000 t (14.2%). In lithium, Australia produced 92,000 t of about 290,000 t (31.7%), China 62,000 t (21.4%) and Zimbabwe 28,000 t (9.7%). USGS also records net import reliance of 79% for U.S. cobalt and more than 50% for U.S. lithium.

nextmsc.com/industry-deep-dive/lithium-cobalt-rare-earth-prices-2026
NMSC Insight: Concentration matters most where one jurisdiction can change export rules. DR Congo’s quota affects about three-quarters of world cobalt mining.
PILLAR 2
Delivery Basis — The Benchmark Effect
CIF Asia, CIF China-Japan-Korea, EXW China, FOB Australia and in-warehouse Rotterdam are different prices for different points in the chain. Benchmark’s 2 September commentary shows the effect: EXW China carbonate rose 0.3% to RMB 150,300–160,500/t while seaborne CIF Asia carbonate fell 0.8%. For hydroxide, EXW China rose 2.3% to RMB 138,000–144,500/t.
NMSC Insight: Two valid prices can move in opposite directions in the same week. The relevant question for procurement is which price the contract references.
PILLAR 3
Policy Exposure — The Quota and Floor Effect
DR Congo’s quota ceiling of 96,600 t a year for 2026 and 2027, including 9,600 t for strategic reserves, caps exports at roughly 42% of its 2025 mine output (NextMSC calculation). In rare earths, the US$110/kg NdPr floor in the DoD–MP Materials contract sets a minimum for a specific buyer, which Rare Earth Exchanges stresses is not a market price. SMM’s NdPr oxide benchmark was US$96.69/kg on 5 September (via Critical Minerals News), so the floor is about 14% above it (NextMSC calculation).
NMSC Insight: Policy now sets a floor or ceiling on some prices without setting the market price. Treat contractual floors and export quotas as separate inputs from spot assessments.
PILLAR 4
Origin and Qualification — The Provenance Effect
REEx’s September coverage indicates ex-China dysprosium oxide at US$3,250/kg and terbium oxide at about US$7,500/kg, against roughly US$214/kg and US$992/kg in China as stated in the report, or about 15× and 7.5×. REEx also notes that a listed yttrium price of US$9/kg is effectively meaningless when material is unavailable because of export restrictions.
NMSC Insight: For heavy rare earths, a quoted price without a stated origin, permit status and qualification level is incomplete.
Price-Basis and Supply-Pressure Matrix
Price level, regional spread and policy exposure are three separate dimensions. The matrix below sets the three markets against each other on the verified indicators. It is an analytical framework, not a formal ranking, because the underlying indicators come from different agencies and periods.
| Market | Reference baseline | Latest price points | Regional / basis spread | Supply concentration | Policy exposure |
|---|---|---|---|---|---|
| Lithium carbonate | USGS 2025 U.S. contract average: US$9,000/t | Benchmark CIF Asia US$19,750/t (2 Sep); SMM index US$16,158.73/t (30 Sep) | EXW China RMB 150,300–160,500/t vs seaborne CIF Asia; futures LC2610 119,780 CNY/t | Australia 32%, China 21% of 2025 mine output | Zimbabwe concentrate export ban from 1 Jan 2027 (secondary source) |
| Cobalt metal | USGS 2025e LME cash: US$15/lb (about US$33,069/t) | Fastmarkets Rotterdam US$23.75–27.15/lb (2 Sep); SMM China domestic US$45,278/t (4 Sep) | Rotterdam about 24% above China domestic | DR Congo 74%, Indonesia 14% | DR Congo quota up to 96,600 t/yr; U.S. net import reliance 79% |

The matrix shows four conditions: easing (lithium), policy-led (cobalt), origin-split (heavy rare earths) and floor-supported (NdPr).
Metal-Level Case Studies
Rather than apply the framework to every product, NMSC selects seven contrasting price series to show how reference price, delivery basis, policy and origin interact. The full set of records is available in the Dataset Explorer below.
Lithium carbonate
SEABORNE EASING + CHINA DOMESTIC DIVERGENCE
Benchmark assessed battery-grade carbonate at US$19,750/t CIF Asia on 2 September, down 0.8% week on week, while EXW China carbonate rose 0.3% to RMB 150,300–160,500/t, supported by seasonal demand and the revoked environmental approval at CATL’s Jianxiawo mine. By 30 September SMM’s index was US$16,158.73/t, down US$75.39 on the day. USGS’s 2025 U.S. contract average of US$9,000/t is the baseline.
Lithium hydroxide
FEWER PRODUCERS + SHARPER MOVES
Benchmark assessed hydroxide at US$18,750/t, up 2.7% week on week, with EXW China up 2.3% on higher NCM cathode and cell production. SMM’s hydroxide index was US$14,930.71/t on 30 September, down US$203.05 on the day, the larger absolute daily drop of the two SMM lithium indices. Benchmark notes hydroxide is supplied by fewer producers than carbonate.
Spodumene concentrate
FEEDSTOCK LOOSENING
Benchmark assessed 6% Li2O spodumene at US$2,254/t FOB Australia, down 0.8%, within a range of US$2,205–2,302/t. An auction after the assessment cleared at US$2,277/t. Benchmark attributes the loosening to Chinese converters finishing maintenance and rising arrivals of Zimbabwean material. USGS records spodumene at about US$800/t in January 2025 and US$970/t in November 2025.
Cobalt metal
TWO TRACKS + QUOTA-LED SUPPLY
Fastmarkets assessed Rotterdam standard grade at US$23.75–27.15/lb on 2 September (mid-point about US$56,108/t), while SMM’s China domestic price was US$45,278/t on 4 September. USGS estimates 2025 U.S. imports of 14,000 t and year-end industry stocks of 1,500 t, up from 10,800 t and 956 t in 2024. USGS’s estimated 2025 U.S. spot cathode average was US$21/lb.
NdPr (neodymium–praseodymium)
FLOOR VS MARKET
SMM’s NdPr oxide benchmark was US$96.69/kg on 5 September (via Critical Minerals News), and REEx cites a Chinese domestic range of 719–739 CNY/kg on 17 September. The DoD–MP Materials floor of US$110/kg is about 14% above the SMM benchmark. SMM’s Pr-Nd alloy mid-point was US$118,091.47/t on 30 September.
Dysprosium
ORIGIN SPLIT
Chinese domestic dysprosium oxide was 1,410–1,450 CNY/kg on 23 September, which REEx states as about US$214/kg, against a North American transaction at US$3,250/kg, about 15×. SMM’s dysprosium metal was US$233.55/kg and dysprosium-iron alloy US$180,920.08/t on 30 September. The North American figure is a single transaction.
Terbium
ORIGIN SPLIT + HIGHEST PRICE POINT
Chinese terbium oxide was 6,585–6,645 CNY/kg on 23 September, about US$992/kg per REEx, against a North American transaction at about US$7,500/kg, about 7.5×. SMM’s terbium metal was US$1,074.34/kg on 30 September, the highest of the five metals in Figure 3.

Methodology and Data Limitations
The NMSC analysis compares critical-mineral prices across agencies, delivery points and origins to show where headline numbers differ. The objective is to help buyers choose the right reference price, not to forecast a single market price.
Methodology
- Government baselines come from USGS Mineral Commodity Summaries 2026 for lithium and cobalt (February 2026).
- Current prices come from Benchmark Mineral Intelligence, Shanghai Metals Market, Fastmarkets and, where stated, secondary reporting of those agencies. Rare earth transaction data and the CREIA index come from Rare Earth Exchanges reporting.
- Pound-to-tonne conversions use 2,204.62 lb per tonne; for example, US$15/lb equals about US$33,069/t. CNY prices are shown in CNY and are not converted to USD, except where the source states a USD figure.
- Percentages, ratios and shares marked as NextMSC calculations are arithmetic on the cited figures. Each is shown with its inputs and dates.
Data Limitations
- Agency prices use different delivery bases (CIF Asia, CIF China-Japan-Korea, EXW China, FOB Australia, Rotterdam in-warehouse) and are not interchangeable.
- Prices from different dates are compared only where flagged; for example, Rotterdam cobalt (2 September) and China domestic cobalt (4 September) differ by two days and by VAT basis.
- GFEX futures are not spot prices. Single transactions, such as North American dysprosium and terbium, are indicative and not benchmarks.
- Records marked “Supplied dataset; not re-opened” in the Dataset Explorer were provided to NextMSC and could not be re-checked at the original source on the cut-off date. Aggregator observations are shown for completeness.
- USGS rare earth data was not retrieved for this edition, so rare earth supply concentration is not reported.

Key Findings
One metal, several valid prices
Benchmark’s US$19,750/t and SMM’s US$16,158.73/t for lithium carbonate are both genuine assessments; agency, date and delivery basis explain the gap.
Lithium has turned down
SMM’s carbonate index fell 16.1% from 8 to 30 September, and the GFEX curve slopes down about 3.2% from LC2610 to LC2703.
Cobalt is policy-led
DR Congo supplies 73% of world mine output and capped exports at up to 96,600 t a year for 2026–27, about 42% of its 2025 production.
Cobalt trades on two tracks
Rotterdam metal sits about 24% above China domestic, so the basis matters as much as the level.
Rare earth prices depend on origin
North American dysprosium and terbium transactions sit at about 15× and 7.5× Chinese reference levels, as reported.
Floors are not markets
The US$110/kg NdPr floor is about 14% above SMM’s US$96.69/kg benchmark and applies to a specific contract.
Concentration shapes exposure
DR Congo holds about 74% of cobalt mining and Australia about 32% of lithium mining, so single-country events move prices.
The reference price is now a decision
The most robust procurement approach pairs the right benchmark with the right delivery point, origin and policy exposure.

Conclusion
Critical-mineral prices in 2026 can no longer be summarised with one number. Lithium has moved from a September high toward lower agency prices and a gently downward-sloping futures curve. Cobalt prices are held up by DR Congo’s quota regime and split by region. Rare earths show the widest origin-based spreads, with ex-China dysprosium and terbium transactions at multiples of Chinese reference prices. In each market, the question that decides the outcome for a buyer is which benchmark, which delivery point and which origin the contract references.
Export policy and contractual floors now shape prices alongside supply and demand, and some prices, such as the NdPr floor and single transactions, serve different purposes from market benchmarks. Buyers who treat one headline number as the market risk misreading cost and supply security. NextMSC’s framework of reference price, delivery basis, policy exposure and origin is a starting point for that fuller view, not a forecast. This tracker will be refreshed monthly.
