What it means
A standardised futures contract can allow more than one valid way to perform, and the seller's permitted choice is valuable because some eligible deliveries are cheaper or more convenient than others. The buyer accepts that range of performance when entering the contract.
CME describes the short position as holding the delivery optionality in Treasury futures, while the long is passive until assigned. The quality option is an important example in Treasury futures, where several eligible securities can satisfy the contract.
The short considers their prices, conversion factors and other relevant costs rather than delivering an arbitrary bond. Cheapest to deliver describes the security that is economically most attractive under the relevant calculation, and it is a result of comparing permitted alternatives, not a permission to ignore eligibility.
A bond with a low quoted price may still be expensive after the invoice adjustment, and a security that was cheapest earlier may no longer be cheapest after yields move. The timing option allows delivery on eligible dates, so the preferred date can change if market prices or financing conditions change during the window.
Hedgers exposed to one bond or commodity location can therefore face basis changes as delivery incentives shift. Some timing features are called end-of-month or wildcard options, and their value arises from the interaction between futures trading times, delivery intentions and underlying market prices.
They should be described as product-specific mechanisms rather than universal features of every future. Location or grade alternatives appear in some commodity contracts, where rules may attach premiums or discounts, so a short cannot simply choose a convenient location and require the long to accept it without the contractual adjustment.
A delivery option is embedded in the contract rather than bought through a separate option premium, so its economic value can be reflected in the futures price and basis relationships. The absence of a separate invoice does not make the choice valueless.
Valuing it requires more than comparing purchase prices, since financing, storage, accrued interest, conversion factors and timing can all affect the actual economics. The long position needs to plan for the permitted set of deliveries, because a buyer wanting one exact security or local commodity lot may find that the futures obligation does not guarantee it.
Eligibility restrictions such as maturity, grade and facility rules keep the embedded choice inside defined boundaries. For a non-finance manager, the contract states what the seller may choose and analysis estimates what the seller is likely to choose, but neither guarantees a particular outcome until the relevant process fixes it.
In practice
Real-world examples.
Example
A Treasury futures seller compares eligible bonds after adjusting for conversion factors. The cheapest quoted bond is not automatically the cheapest security to deliver against the contract, so the seller runs the full invoice and financing calculation for each candidate before choosing.
Example
A commodity future permits delivery from several approved territories with stated adjustments. The seller compares the actual adjusted proceeds and transport costs before choosing an eligible location, rather than assuming the nearest warehouse is best.
Example
A buyer uses a futures hedge for exposure to one particular bond. Changes in the expected cheapest-to-deliver security alter the basis, leaving a mismatch between the hedge and the exact bond held, which the risk team reports as basis risk.
Formula
Calculation
Adjusted delivery cost = Asset purchase cost - Delivery invoice received + Carrying costs
Worked example. A short position can deliver either of two simplified alternatives.
- Alternative A costs $101,000 to buy, produces a $100,500 invoice and adds $100 of carrying cost, so the adjusted cost is $101,000 - $100,500 + $100 = $600.
- Alternative B costs $99,800, produces a $99,400 invoice and adds $50, so the adjusted cost is $99,800 - $99,400 + $50 = $450.
Under these simplified assumptions B is cheaper by $600 - $450 = $150, so B is the likely cheapest to deliver. Actual futures comparison requires the full product-specific calculation.Case study
Seen in the real world.
Fictional case: A dealer initially plans to deliver one eligible Treasury security. After yields change, another security becomes cheaper after invoice adjustments and financing. The dealer verifies eligibility and compares the complete settlement economics before changing its plan. The receiving team knows the contract permits several securities, so it does not assume the first expected bond is guaranteed.
Both teams distinguish the contract's embedded choice from a speculative prediction about its exercise. In the illustrative story, the dealer, Corvus Securities, found that the switch saved $150 per contract compared with the original plan, which on 40 contracts came to 40 x $150 = $6,000. It recorded the comparison in its settlement file, so auditors could see that the choice was made on documented economics and within the contract's eligibility rules.
Watch out
Common mistakes.
- Treating an embedded delivery choice as an unrestricted right to change contract terms.
- Selecting the cheapest quoted asset without invoice adjustments and carrying costs.
- Assuming every futures contract has identical timing, quality and location options.

Who commonly holds the choice?

Is it a separate call or put?
No. It is a choice embedded in the delivery contract.
Can it create basis risk?
Yes. Changes in the preferred eligible delivery can affect hedging relationships.
