Cobalt Price — 10-Day Trend

Cobalt Doesn't Trade Quite Like Copper Does
Ask how copper is priced and the answer is straightforward: it trades continuously on the London Metal Exchange, with a price discovered directly through open buying and selling. Ask the same question about cobalt and the answer gets more interesting. The LME does list a cobalt contract — but its full name is telling: LME Cobalt (Fastmarkets MB). That parenthetical isn't decoration. It means the contract's final settlement price is based on the mid-point of a daily price range published by Fastmarkets, a price reporting agency, rather than being discovered purely through the exchange's own open trading.
Today's reference rate of ₹3.56 per gram sits downstream of that same assessment-driven system — worth understanding if you've ever wondered why cobalt price reporting reads a little differently from gold or copper coverage.
- LME Cobalt (Fastmarkets MB): standard contract size of 1 tonne, quoted in USD/tonne
- Settlement basis: the mid-price of Fastmarkets' own daily published range, not raw LME order-book trading alone
- Fastmarkets' role: widely treated as the cobalt industry's benchmark price-reporting agency

What a Price Reporting Agency Actually Does
Fastmarkets isn't a stock exchange and it isn't a broker. It's a price reporting agency — an organization whose job is to survey real transactions happening across the physical market and publish a representative price based on what it observes, following methodologies designed to meet international standards for price-reporting agencies (the IOSCO principles), with published assessments going through an internal peer-review process before release. Its core cobalt assessment, standard-grade cobalt metal in-warehouse Rotterdam, quoted in US dollars per pound, is the number most of the industry treats as the reference point — and it's also the number CME Group's own cobalt futures contract ultimately settles against.
Why this model exists for cobalt specifically
Assessment-based pricing tends to show up where a market's physical trading is real but not deep or continuous enough to support the kind of always-on, transparent price discovery that a metal like copper or aluminium gets from decades of heavy exchange volume. Cobalt's physical market is smaller and more geographically concentrated than copper's, and a meaningful share of global supply moves through long-term contracts rather than spot trades — conditions that make a carefully surveyed assessment a more practical benchmark than trying to force continuous open-outcry trading onto a thinner market.
That's not a knock on cobalt's market — it's simply a different, and in some ways more transparent-by-design, mechanism: instead of trusting that enough trades happen on an exchange floor to produce a fair number, the price reporting agency's whole job is making sure the surveyed number reflects what real transactions actually looked like.

What This Means for Anyone Watching the Cobalt Price
Practically, it means cobalt price moves can look and feel a little different from a metal traded on pure open-market mechanics. Because Fastmarkets' assessment reflects a survey of real transactions rather than a live tick-by-tick order book, cobalt prices can sometimes appear to move in steadier steps day to day, and headline commentary about "the cobalt price" is really referencing this same underlying assessment process, whichever specific outlet is reporting it.
It's also a reminder that "the cobalt price" isn't one single number the way it can feel like gold has one number — there's LME Cobalt (Fastmarkets MB) for the futures market, Fastmarkets' own standard-grade and hydroxide assessments for the physical market, and battery-grade cobalt sulfate prices that move on their own separate track again (covered on this site's dedicated cobalt sulfate page). Knowing which one a given headline is actually referring to is worth more than memorizing any single figure.
Cobalt Price Benchmarks — FAQs
Not in quite the same way. The London Metal Exchange lists a cobalt contract, but it is formally named LME Cobalt (Fastmarkets MB), and its final settlement price is based on the mid-point of the daily price range published by Fastmarkets — a price reporting agency — rather than being discovered purely through open trading the way LME copper or aluminium prices are.
Fastmarkets is a price reporting agency widely treated as the industry-standard source for cobalt price assessments, including a benchmark standard-grade cobalt price and a separate cobalt hydroxide price used across the battery supply chain. Its methodology follows IOSCO principles for price-reporting agencies, with an internal peer-review process on its published assessments.
The standard LME Cobalt (Fastmarkets MB) contract size is 1 tonne, quoted in US dollars per metric ton — small next to a metal like copper's LME lot size, reflecting cobalt's much smaller and less liquid physical trading market.
Cobalt's physical market is smaller, more concentrated in one producing country, and historically less liquid than copper or gold's. Assessment-based pricing — where a price reporting agency surveys real transactions and publishes a representative price — has become the industry's practical solution where continuous, deep, transparent open-market trading hasn't developed the way it has for the larger base and precious metals.
