## The Core Distinction in Market Practice

The [FX Global Code](https://prime.greeks.live/area/fx-global-code/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) delineates between last look and pre-hedging by defining their operational boundaries and permissible applications within the trade lifecycle. Last look is identified as a risk control mechanism exercised by a liquidity provider at the moment of [trade request](https://prime.greeks.live/question/in-what-specific-scenarios-should-a-request-for-quotation-be-used-instead-of-a-request-for-proposal/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), affording a final opportunity to accept or reject the request at the quoted price. Pre-hedging, conversely, is the management of risk that a market maker undertakes in anticipation of a client order, conducted before the trade itself is executed. The fundamental separation lies in the timing and the nature of the information used.

Last look is a post-quote, pre-execution decision point, while pre-hedging is a pre-trade risk mitigation strategy. The Code’s guidance on these practices reflects a deep understanding of the complexities of market making and the potential for information asymmetry. It seeks to create a framework where both practices can exist, provided they are governed by principles of [transparency](https://prime.greeks.live/area/transparency/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) and fairness. The distinction is a critical component of the Code’s efforts to foster a more robust and equitable [foreign exchange market](https://prime.greeks.live/area/foreign-exchange-market/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite).

## Last Look as a Risk Management Tool

Last look, as framed by the FX Global Code, is a practice within electronic trading activities that allows a [market participant](https://prime.greeks.live/question/which-type-of-market-participant-benefits-most-from-a-crumbling-quote-indicator/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) receiving a trade request a final moment to accept or reject it against the quoted price. This mechanism is intended to protect [liquidity providers](https://prime.greeks.live/area/liquidity-providers/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) from adverse price movements that may occur in the latency between quoting a price and receiving a trade request. The Code does not prohibit last look but places significant emphasis on its transparent and fair application. Principle 17 of the Code is dedicated to this practice, outlining the expectations for market participants who utilize it.

The guidance has evolved to address concerns from the buy-side about potential misuse, particularly regarding the information gleaned from rejected trades. The GFXC has clarified that trading activity based on information from a client’s trade request during the [last look window](https://prime.greeks.live/area/last-look-window/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) is likely inconsistent with good market practice. This clarification is central to differentiating legitimate risk control from opportunistic trading. The Code requires that liquidity providers disclose their use of last look, including the length of the last look window and the rationale for trade rejections. This transparency is designed to empower clients to make informed decisions [about their execution counterparties](https://prime.greeks.live/question/how-do-central-counterparties-adjust-their-margin-models-in-response-to-market-stress-events/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite).

## Pre-Hedging within a Fiduciary Framework

Pre-hedging is addressed under [Principle 11](https://prime.greeks.live/area/principle-11/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) of the FX Global Code, which permits the practice under specific conditions. It is defined as the management of risk associated with an anticipated client order, which a market participant may undertake before the execution of that order. The Code stipulates that [pre-hedging should](https://prime.greeks.live/question/how-can-pre-hedging-by-dealers-be-differentiated-from-normal-market-noise/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) only be conducted when the market participant is acting as a principal, ensuring that the risk is being managed on their own book. Furthermore, the practice must be executed fairly and with transparency to the client.

This means that clients should be made aware of their counterparty’s potential to pre-hedge and the [circumstances under which](https://prime.greeks.live/question/under-what-circumstances-can-a-buyer-cancel-an-rfp-process-after-bids-have-been-submitted/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) it might occur. The intention is to allow market makers to manage their risk effectively, which can contribute to tighter pricing and deeper liquidity for clients. However, the Code is clear that pre-hedging should not be detrimental to the client’s interests. The market participant must have a reasonable basis for believing that the pre-hedging activity will not disadvantage the client’s execution. This places a significant onus on the [market maker](https://prime.greeks.live/question/how-does-a-market-makers-confirmation-threshold-strategy-impact-both-capital-efficiency-and-market-risk/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) to have robust internal controls and a clear ethical framework governing their pre-hedging activities.

## Navigating the Complexities of Execution

The strategic implications of [last look](https://prime.greeks.live/area/last-look/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) and [pre-hedging](https://prime.greeks.live/area/pre-hedging/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) are significant for both liquidity providers and their clients. For liquidity providers, these practices are tools for managing the inherent risks of market making in a high-speed, electronic environment. The ability to employ last look allows them to offer tighter spreads than they might otherwise be comfortable with, knowing they have a final opportunity to decline a trade if the market has moved against them. Pre-hedging allows them to manage their inventory and risk exposure in anticipation of large client orders, which can facilitate smoother execution and reduce market impact.

For clients, the strategic challenge is to understand how these practices are being applied by their counterparties and to assess the impact on their execution quality. The transparency requirements of the FX Global Code are designed to provide clients with the information they need to make these assessments. A sophisticated client will develop a strategy for engaging with liquidity providers that takes into account their stated policies on last look and pre-hedging. This may involve favoring counterparties who provide detailed disclosures or who have adopted practices that are more aligned with the client’s own execution objectives.

> The FX Global Code provides a framework for the responsible use of last look and pre-hedging, emphasizing transparency and fairness to maintain market integrity.

## Last Look a Controversial Practice

The controversy surrounding last look stems from the potential for information leakage and the perceived unfairness of a liquidity provider rejecting a trade after a client has acted on a quoted price. Critics argue that the practice gives market makers a free option, allowing them to benefit from favorable price movements while avoiding unfavorable ones. The concern is that even if a trade is rejected, the liquidity provider has gained valuable information about the client’s trading intentions, which could be used to their advantage. The FX Global Code has sought to address these concerns by tightening the rules around what is permissible during the last look window.

The guidance that trading on the information from a client’s request during this period is likely inconsistent with good market practice is a direct response to these criticisms. However, the debate continues, with some market participants advocating for the complete abolition of last look. They argue that it creates an uneven playing field and undermines trust in the market. Proponents of the practice maintain that it is a necessary [risk management](https://prime.greeks.live/area/risk-management/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) tool that ultimately benefits clients by allowing for the provision of tighter spreads and deeper liquidity.

## The Evolution of Last Look Guidance

The [GFXC](https://prime.greeks.live/area/gfxc/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite)’s approach to last look has evolved since the initial publication of the Code. The committee has actively sought feedback from market participants and has demonstrated a willingness to amend the guidance in response to industry concerns. The clarification regarding trading activity during the last look window is a key example of this iterative process. The GFXC has also published guidance papers to provide further clarity on specific use cases, such as “cover and deal” arrangements.

This ongoing refinement of the Code reflects the dynamic nature of the FX market and the commitment of the GFXC to ensuring that the principles of good practice remain relevant and effective. The evolution of the guidance on last look demonstrates the GFXC’s role as a steward of the market, balancing the commercial needs of liquidity providers with the imperative of maintaining a fair and transparent trading environment.

## Pre-Hedging a Double Edged Sword

Pre-hedging presents its own set of strategic challenges and ethical considerations. While it can be a legitimate and even beneficial practice for both market makers and clients, it can also be misused. The potential for misuse arises from the information asymmetry between the market maker and the client. The market maker, aware of an impending large order, could pre-hedge in a way that moves the market against the client, resulting in a less favorable execution price.

This is why the FX Global Code places such a strong emphasis on [fairness and transparency](https://prime.greeks.live/area/fairness-and-transparency/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). A market maker’s pre-hedging strategy must be designed to mitigate their own risk without being detrimental to the client. This requires a sophisticated understanding of market dynamics and a robust ethical framework. The Code’s requirement that pre-hedging only be undertaken by a [market participant acting](https://prime.greeks.live/question/what-are-the-key-differences-in-best-execution-for-an-si-versus-a-broker-acting-as-agent/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) as a principal is also a crucial safeguard. It ensures that the market maker has skin in the game and is not simply front-running a client’s order for a risk-free profit.

## Client Communication and Disclosure

Effective communication and disclosure are central to the responsible use of both last look and pre-hedging. The FX Global Code requires market participants to be clear and transparent with their clients about their practices. For last look, this includes disclosing the length of the last look window, the criteria for rejecting trades, and providing timely and clear reasons for rejections. For pre-hedging, it involves informing clients of the circumstances under which it may occur and how the market participant ensures that the practice is not to the client’s detriment.

The GFXC has developed disclosure cover sheets to help liquidity providers and e-trading platforms provide this information in a standardized and accessible format. This emphasis on disclosure is designed to empower clients, allowing them to make informed choices about their execution counterparties and to hold them accountable for their practices.

The following table outlines the key principles of the FX Global Code related to last look and pre-hedging:

## Implementing the FX Global Code

The successful implementation of the FX Global Code’s principles on last look and pre-hedging requires a concerted effort from all market participants. For liquidity providers, it means establishing robust internal controls, providing comprehensive training to staff, and developing clear and transparent disclosures for clients. It also involves a commitment to ongoing monitoring and review to ensure that their practices remain consistent with the Code’s principles and evolving market standards. For clients, implementation means taking an active role in understanding and evaluating the practices of their counterparties.

This includes reviewing disclosures, asking pertinent questions, and using the information available to them to make informed decisions about where to execute their trades. The GFXC supports implementation through the publication of guidance papers, templates, and other materials designed to help market participants understand and adhere to the Code. The ultimate goal is to create a market where all participants have confidence that they are being treated fairly and that the execution process is transparent and efficient.

> Adherence to the FX Global Code’s principles on last look and pre-hedging is essential for maintaining a fair, transparent, and efficient foreign exchange market.

## Best Practices for Last Look

A liquidity provider’s implementation of last look should be guided by the principles of [fairness](https://prime.greeks.live/area/fairness/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), transparency, and consistency. The following are some [best practices](https://prime.greeks.live/area/best-practices/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) for the application of last look, in line with the FX Global Code:

- **Clear Disclosure** ▴ Liquidity providers should provide clients with a clear and comprehensive disclosure of their last look practices. This should include the length of the last look window, the circumstances under which a trade may be rejected, and how rejections will be communicated.

- **Consistent Application** ▴ The application of last look should be consistent and based on pre-defined criteria. It should not be used to discriminate between clients or to take advantage of market conditions in an opportunistic manner.

- **Timely Rejection** ▴ If a trade is to be rejected, the rejection should be communicated to the client in a timely manner. The reason for the rejection should also be provided, where possible, to help the client understand the outcome.

- **No Trading on Client Information** ▴ As per the GFXC’s guidance, liquidity providers should not engage in trading activity that utilizes information from a client’s trade request during the last look window. This is a critical element of fair practice.

## Best Practices for Pre-Hedging

The responsible implementation of pre-hedging requires a strong ethical framework and a commitment to client interests. The following are some best practices for pre-hedging, consistent with the principles of the FX Global Code:

- **Acting as Principal** ▴ Pre-hedging should only be undertaken when the market participant is acting as a principal and has a legitimate reason to manage their own risk.

- **Fairness and Transparency** ▴ Clients should be made aware of the market participant’s pre-hedging practices. The pre-hedging activity should be conducted in a way that is not detrimental to the client’s execution.

- **Risk Management Focus** ▴ The primary purpose of pre-hedging should be risk management, not speculation. The size and timing of the pre-hedging trades should be proportionate to the anticipated client order and the market conditions.

- **Confidentiality** ▴ Information about a client’s anticipated order should be treated with the utmost confidentiality and should only be accessible to those who need to know for the purposes of risk management.

> The FX Global Code’s guidance on last look and pre-hedging has been instrumental in promoting greater transparency and fairness in the foreign exchange market.
