## The Language of Bespoke Settlement

The [FIX protocol](https://prime.greeks.live/area/fix-protocol/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), the lingua franca of global financial markets, possesses a robust and flexible framework for negotiating trade parameters that deviate from the standard settlement cycle. The mechanism for establishing a bespoke settlement date is not confined to a single message type; it is a process embedded within the pre-trade and post-trade message flows. This process allows counterparties to agree upon specific, [non-standard terms](https://prime.greeks.live/question/how-does-a-non-binding-rfp-differ-from-a-binding-tender-in-terms-of-legal-risk/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) with clarity and precision, ensuring that the operational aspects of a trade align with the strategic intent of the participants.

At the heart of this capability lies the [Stipulations component block](https://prime.greeks.live/question/why-is-the-cover-2-standard-a-critical-component-of-ccp-risk-management/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), a repeating group of fields that can be embedded within a variety of pre-trade messages. This block acts as a container for conveying specific trade conditions that are not covered by the standard fields of a message. The two key fields within this block are StipulationType (tag 233) and StipulationValue (tag 234).

The StipulationType field specifies the condition being negotiated, while the StipulationValue field provides the specific parameter for that condition. For the purpose of negotiating a bespoke settlement date, the StipulationType would be set to “CUSTOMDATE”, and the StipulationValue would contain the agreed-upon date.

> The core of bespoke settlement negotiation in FIX lies in the pre-trade communication of non-standard terms through the use of stipulations.

The negotiation process typically begins with one party communicating their desire for a [non-standard settlement](https://prime.greeks.live/question/what-is-the-difference-between-physical-settlement-and-cash-settlement-for-crypto-options/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) date in an Indication of Interest (IOI), Quote Request, or New Order message. The other party can then accept, reject, or counter the proposed stipulation in their response. This back-and-forth communication, all conducted through standard FIX messages, allows for a clear and auditable trail of the negotiation. Once the terms are agreed upon, the bespoke settlement date is carried through to the execution and allocation messages, ensuring that the trade is settled correctly.

## Key Fields in Settlement Negotiation

While the Stipulations block is central to the negotiation, other fields and messages play a crucial role in the overall process. The SettlType (tag 63) and [SettlDate](https://prime.greeks.live/area/settldate/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (tag 64) fields are also used to communicate [settlement terms](https://prime.greeks.live/question/what-is-the-difference-between-physical-settlement-and-cash-settlement-for-crypto-options/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). SettlType specifies the settlement type (e.g.

Regular, Cash, Next Day), while SettlDate provides the specific settlement date. In the context of a bespoke settlement, the Stipulations block would be used to propose and agree upon the date, which would then be populated in the SettlDate field in the [post-trade messages](https://prime.greeks.live/question/can-a-series-of-text-messages-or-instant-messages-following-an-rfp-also-create-a-legally-binding-contract/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite).

The primary messages involved in this process include:

- **New Order – Single (MsgType=D)** ▴ Used to submit an order with a bespoke settlement date stipulation.

- **[Execution Report](https://prime.greeks.live/area/execution-report/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (MsgType=8)** ▴ Confirms the execution of the trade and carries forward the agreed-upon settlement date.

- **[Allocation Instruction](https://prime.greeks.live/area/allocation-instruction/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (MsgType=J)** ▴ Used by a broker to provide the breakdown of a [block trade](https://prime.greeks.live/question/what-are-the-pre-trade-analytics-to-consider-before-executing-a-crypto-block-trade/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) to a clearinghouse, including the bespoke settlement date for each allocation.

- **[Confirmation](https://prime.greeks.live/area/confirmation/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (MsgType=AK)** ▴ Confirms the details of a trade between counterparties, including the bespoke settlement date.

The flexibility of the FIX protocol allows for a high degree of customization in trade negotiations, enabling market participants to tailor their transactions to meet specific funding, hedging, or operational requirements. This capability is particularly important in markets where non-standard settlement cycles are common, such as in certain fixed-income or derivatives markets.

## A Strategic Approach to Bespoke Settlement

The negotiation of a bespoke settlement date within the FIX protocol is a strategic process that requires a clear understanding of the available message flows and the specific fields that govern settlement terms. The primary strategy involves the use of the [Stipulations component](https://prime.greeks.live/question/why-is-the-cover-2-standard-a-critical-component-of-ccp-risk-management/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) block in pre-trade messages to propose and agree upon a non-standard settlement date. This approach provides a clear and auditable record of the negotiation, minimizing the risk of settlement errors and disputes.

The process begins with the initiator of the trade including the Stipulations block in their initial message, typically a New Order – Single or Quote Request. The StipulationType field is set to “CUSTOMDATE”, and the StipulationValue field contains the desired settlement date. The receiver of the message can then respond with an Execution Report that either accepts the proposed settlement date or a Quote Status Report that rejects or counters the proposal. This iterative process continues until both parties agree on the settlement terms.

> A successful bespoke settlement strategy hinges on the clear communication of terms in the pre-trade phase and the accurate carry-through of those terms to post-trade messages.

Once the trade is executed, the agreed-upon settlement date is then carried forward in the SettlDate field of the Execution Report and subsequent post-trade messages, such as the Allocation Instruction and Confirmation. This ensures that all parties involved in the settlement process, including custodians and clearinghouses, are aware of the [non-standard settlement terms](https://prime.greeks.live/question/how-does-a-non-binding-rfp-differ-from-a-binding-tender-in-terms-of-legal-risk/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite).

## Comparative Analysis of Settlement Negotiation Methods

The FIX protocol provides several mechanisms for communicating settlement terms, each with its own advantages and disadvantages. The following table compares the primary methods for negotiating a bespoke settlement date:

| Method | Primary Messages | Key Fields | Advantages | Disadvantages |
| --- | --- | --- | --- | --- |

![Abstractly depicting an Institutional Grade Crypto Derivatives OS component. Its robust structure and metallic interface signify precise Market Microstructure for High-Fidelity Execution of RFQ Protocol and Block Trade orders](https://options.greeks.live/wp-content/uploads/2025/07/principals-integrated-crypto-derivatives-rfq-protocol-architecture.jpg)

## The Role of Post-Trade Messages

The post-trade messaging flow is critical for ensuring that the agreed-upon bespoke settlement date is correctly processed and settled. The Allocation Instruction message, in particular, plays a key role in this process. This message is used by a broker to provide the breakdown of a block trade to a clearinghouse, and it includes the SettlDate for each individual allocation. This ensures that each portion of the block trade is settled on the correct date, even if the settlement dates differ between allocations.

The Confirmation message is also an important part of the post-trade process. This message is exchanged between the counterparties to a trade to confirm the details of the transaction, including the bespoke settlement date. This provides a final opportunity to identify and correct any discrepancies before the trade is sent for settlement.

## Executing a Bespoke Settlement

The execution of a trade with a bespoke settlement date requires a precise and well-coordinated messaging flow between the counterparties and any intermediaries involved in the settlement process. The following is a step-by-step guide to the execution of a trade with a non-standard settlement date using the FIX protocol:

- **Pre-Trade Negotiation** ▴ The initiator of the trade sends a New Order – Single message with the Stipulations [component block](https://prime.greeks.live/question/why-is-the-cover-2-standard-a-critical-component-of-ccp-risk-management/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) included. The StipulationType is set to “CUSTOMDATE” and the StipulationValue is set to the desired settlement date.

- **Execution Confirmation** ▴ The receiver of the order responds with an Execution Report message, confirming the execution of the trade. This message includes the SettlDate field, populated with the agreed-upon settlement date.

- **Allocation and Clearing** ▴ If the trade is part of a block trade, the broker sends an Allocation Instruction message to the clearinghouse. This message includes the SettlDate for each allocation, ensuring that each portion of the trade is settled on the correct date.

- **Trade Confirmation** ▴ The counterparties exchange Confirmation messages to confirm the details of the trade, including the bespoke settlement date. This provides a final opportunity to identify and correct any discrepancies before the trade is sent for settlement.

This process ensures that all parties involved in the trade are aware of the non-standard settlement terms and that the trade is settled correctly and efficiently. The use of the Stipulations component block in the pre-trade negotiation provides a clear and auditable record of the agreed-upon terms, minimizing the risk of settlement errors and disputes.

> The precise execution of a bespoke settlement trade relies on the accurate and consistent use of the Stipulations and SettlDate fields throughout the entire trade lifecycle.

## Advanced Considerations

In addition to the primary message flow described above, there are several advanced considerations that may come into play when negotiating a bespoke settlement date. For example, in some markets, it may be necessary to use a SecurityDefinition message to define a security with a non-standard settlement cycle. This is particularly common in the fixed-income markets, where securities with non-standard settlement terms are more prevalent.

Furthermore, the use of a TradeCaptureReport message may be required in some cases to report the details of a trade with a bespoke settlement date to a regulatory authority or a trade repository. This message includes all of the relevant details of the trade, including the SettlDate and any other non-standard terms.
