What it means
A basis quote states a price as a spread to a reference price, usually a nearby futures contract or a government bond yield. The reference does the heavy lifting, so the two sides only have to agree the small difference that reflects quality, location, timing or credit.
The outright price appears later, once the benchmark is observed and the spread is added or subtracted. This matters commercially because the benchmark moves all day while the basis usually moves slowly.
A buyer who agrees a basis of 20 cents over futures has locked the part of the deal that is specific to this trade, with this counterparty, at this delivery point. The buyer can then choose the moment to fix the benchmark leg, which splits one hard decision into two easier ones.
In practice a grain buyer may quote a basis for delivery into one particular elevator, while a bond dealer quotes a corporate issue in basis points over the comparable government bond. Both are saying the same thing: the market sets the base, and the negotiation is about the premium or discount on top.
Nobody has to agree on where the wider market is going. Finance teams care because invoices, hedge records and the ledger all need a single outright figure in the end.
The usual sequence is to agree the basis, then fix the benchmark leg, then combine the two into a confirmed amount. Until the second step happens, the contract value in a forecast is an estimate, not a commitment.
The nuance is that a basis is not risk free. It can widen or narrow as local supply, credit quality or delivery conditions change, and that residual exposure is called basis risk.
A hedge built on futures removes most of the price movement but leaves this smaller gap, which is why experienced buyers watch the basis as closely as the headline price.
In practice
Real-world examples.
Example
A coffee roaster buys ten containers of beans at 12 cents a pound over the nearby futures price, delivered to its own warehouse. The buying team waits three weeks before fixing the futures leg because it expects the benchmark to soften. The basis stays at 12 cents throughout, so only the timing of the benchmark decision changes the final invoice.
Example
A corporate treasurer is quoted a new bond issue at 145 basis points over the comparable government bond rather than at a fixed yield. That lets the pricing call happen minutes before launch, when the government yield is observed and the final coupon is set. The treasurer negotiates hard on the 145, and accepts the government yield as given.
Example
A diesel distributor sells to a haulage fleet at 8 cents a litre over a published regional benchmark. Both sides stop arguing about the oil price, which neither controls, and negotiate only the 8 cents that covers delivery, storage and margin. The fleet manager can then budget by adding 8 cents to whatever the benchmark shows each week.
Formula
Calculation
Basis = cash price - benchmark price, so cash price = benchmark price + quoted basis.
A food manufacturer agrees to buy 5,000 bushels of wheat on a basis quote of 30 cents over the December futures contract. Three weeks later it fixes the benchmark leg, and December futures settle at $6.20 a bushel. The cash price becomes $6.20 + $0.30 = $6.50 a bushel, so the invoice is 5,000 multiplied by $6.50 = $32,500. Of that total, the basis component is 5,000 multiplied by $0.30 = $1,500, and the benchmark component is 5,000 multiplied by $6.20 = $31,000.Case study
Seen in the real world.
Northwind Grain Partners is an illustrative, entirely fictional cooperative used here to show how basis quotes work in a trading year. Its buyers purchase from farmers on basis quotes rather than fixed prices, typically 25 to 40 cents under the nearby futures contract depending on haulage distance and moisture content. Each contract is then hedged by selling futures, so the cooperative is left holding the basis rather than the price. In the illustrative year, a wet harvest means local grain is plentiful and the basis widens from 30 cents under to 55 cents under. Northwind's hedges perform exactly as designed, yet margin still improves, because the cooperative was buying at a progressively bigger discount to the benchmark it had already sold. The finance director's report notes the obvious lesson: the hedge protected the price, and the basis determined the profit.
Watch out
Common mistakes.
- Treating a basis quote as a final price and loading it into a budget before the benchmark leg has been fixed.
- Assuming the basis is constant, when local shortages, freight problems or credit concerns can move it quickly.
- Describing a futures hedge as risk free, which ignores the basis risk that is left behind after the hedge.
Questions
People also ask.
Is a basis quote only used in commodities?
No, bond, swap and currency markets quote spreads to a benchmark in exactly the same way, usually in basis points.
What does a negative basis mean?
It means the cash price sits below the benchmark, often because local supply is plentiful or the goods on offer are below the contract grade.
Who decides the basis?
The two parties to the trade agree it, based on location, quality, delivery timing and credit, while the benchmark itself is taken from a public market.
