Cobalt rarely stays calm. Supply is concentrated in a handful of jurisdictions, demand is tied to battery chemistry and aerospace alloys, and the metal has spent the past decade moving in doubles rather than single figures. If your business buys cobalt — as metal, powder, sulphate, or contained in a catalyst or a tolling arrangement — you are carrying a price risk whether you have written it down or not.
The good news is that you do not need a trading desk to manage it. You need a clear view of your exposure, a handful of instruments, and the discipline to size them properly.
Start with the exposure, not the instrument
Most hedging mistakes happen before any trade is placed. Buyers hedge the tonnage they purchase rather than the tonnage they are actually exposed to, and then wonder why the accounts do not behave as expected.
Work out your net exposure: annual contained cobalt purchases, minus whatever you can pass through to customers, adjusted for the timing of those pass-throughs. Suppose you consume 150 tonnes a year and 40 per cent of your sales agreements reset quarterly against a published index. Your net exposure is roughly 90 tonnes, and you also carry a timing gap — you buy monthly, but your selling price catches up three months later.
Do not forget stock. Finished goods, work in progress and any consignment inventory sitting with a customer are long positions in cobalt, and they behave like an unfixed purchase. If a customer has placed a fixed-price order with no pass-through clause, you have effectively sold volatility to them.
Your menu of tools
The cobalt market offers fewer shortcuts than copper or aluminium. These are the practical options, roughly in order of how often industrial buyers use them:
- Fixed-price physical contracts. A supplier quote held for a quarter or a year. Simple, no margin, no documentation — but you rarely get a keen price for the certainty.
- Index-linked contracts with a cap or collar. Price floats against an index, but you agree a ceiling, sometimes with a floor and a participation band.
- OTC swaps with a bank or trader. A contract for difference against a reference price, tailored to your tenor and grade. The workhorse for multi-year exposure.
- Exchange futures. Both the LME and CME list cash-settled cobalt contracts referenced to published assessments of standard-grade metal. Useful for shorter-dated, standardised exposure.
- Options and collars. Bought protection, or protection part-funded by selling someone else the downside.
- Structural fixes. Tolling arrangements, recycled feedstock agreements and back-to-back conversion deals that reduce the tonnage you need to hedge at all.
Exhaust the physical contract first
Before you open any financial position, ask your suppliers what they will do. A producer or trader may offer a fixed price for part of your annual requirement, a tiered schedule, or a cap in exchange for a small premium or a share of the upside. These deals cost you no margin, require no ISDA, and sit naturally in your procurement ledger.
Split the requirement. Fix the volume you are confident about, float the rest, and review at each contracting round. A supplier who will not fix 100 per cent of your tonnes may well fix 40 per cent — and that 40 per cent is often the cheapest hedge available to you.
Understand what the futures contract actually references
Exchange contracts settle against an assessment of standard-grade cobalt. Your feedstock may be sulphate, a briquette, a specific grain size or a contained-metal basis in an alloy. The hedge tracks a benchmark, not your material, and the gap between the two is your basis risk. In a tight market, deliverable metal can trade at a premium to sulphate; in a glut it can be the reverse. That spread has broken more hedges than price direction ever has.
Liquidity matters too. Cobalt futures trade far thinner than the major base metals, which means wider bid-offer spreads and slippage if you need to move size quickly. For most industrial consumers this is the argument for doing the bulk of the hedging over the counter with a bank or a large trader, where tenors and grade references can be tailored — accepting counterparty credit risk and proper documentation in return.
Options and collars: pay now or give something up
A bought call gives you the right, not the obligation, to fix a price. You pay a premium up front, you have no margin calls, and you keep the full benefit if the market falls. For a budget you can defend in a board meeting, that is often worth the cost.
A collar — buying the call and selling a put to fund it — cuts or removes the premium. The catch is real: if cobalt drops below your sold strike, you pay out, and your effective cost sits near the capped level even though the market has fallen. That is fine if you budgeted for it and painful if you did not. Never sell an option on a volume you are not genuinely exposed to.
The plumbing: margin, credit and accounting
Financial hedges move cash before they move your cost base. A sharp rally in cobalt can trigger margin calls on a short futures position at the same time as your physical purchases are getting more expensive — the economic offset is real, but the cash timing is not. Agree a facility in advance and let your treasury team see the numbers monthly.
Accounting deserves early attention as well. Under IFRS 9 you may be able to apply hedge accounting so that mark-to-market movements land in the same period as the physical cost. That requires documentation, a defined hedge ratio and a test of effectiveness. Speak to your finance team and auditor before the first trade, not after.
Then write it down. A one-page policy covering who may transact, which instruments are permitted, maximum hedge ratios by tenor, approval thresholds and reporting cadence will save you more money than any clever trade.
A sequence you can follow this quarter
- Map exposure by grade, tonnage and month, and subtract pass-through volumes and inventory.
- Quantify the timing gap between what you pay and what you can charge.
- Decide the proportion of net exposure to fix — many buyers target 50–80 per cent for the next twelve months, less beyond that.
- Use fixed physical deals for the near term, swaps or futures for the standardised middle, and options for volumes you are unsure about.
- Confirm credit lines, documentation and accounting treatment before executing.
- Review monthly against the policy, and report the hedge result alongside the procurement result — never in isolation.
Hedging is not about predicting cobalt. It is about converting an unpredictable number into one your business can plan around, and then being honest about what you gave up to get there. A hedge that looks brilliant on a trading summary but leaves the plant short of cash is not a hedge; it is a second problem.
This is general guidance rather than financial advice. Before transacting, take input from your finance and treasury teams and deal only with regulated counterparties who can explain the credit, margin and accounting consequences of each structure.
