## Concept

The transition to a [T+1 settlement](https://prime.greeks.live/area/t1-settlement/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) cycle in North American securities markets introduces a direct and significant temporal compression that fundamentally challenges the established operational cadence for foreign exchange settlement, particularly through the CLS (Continuous Linked Settlement) system. The core of the issue resides in the misalignment of deadlines. CLS operates as the market’s primary mechanism for mitigating [FX settlement risk](https://prime.greeks.live/area/fx-settlement-risk/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) ▴ the danger that one party to a currency trade pays out but does not receive the corresponding currency from its counterparty.

It achieves this through a [payment-versus-payment](https://prime.greeks.live/area/payment-versus-payment/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) ([PvP](https://prime.greeks.live/area/pvp/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite)) model, a synchronized process that ensures both legs of an FX transaction settle simultaneously. This system, however, is built upon a rigid, globally coordinated timeline with a critical cutoff for payment instructions.

For institutional investors, especially those outside of the United States, the purchase or sale of a US security is intrinsically linked to an FX transaction to source the required US dollars or repatriate proceeds. Under the previous T+2 regime, an asset manager in Europe or Asia had an entire business day following the [securities trade](https://prime.greeks.live/question/how-is-best-execution-measured-and-proven-in-an-rfq-trade-for-illiquid-securities/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (T+1) to execute and submit the related FX trade to [CLS](https://prime.greeks.live/area/cls/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) for settlement on T+2, comfortably aligning the funding with the securities settlement. The shift to T+1 for securities collapses this timeline.

The FX transaction must now be executed and settled on the same day as the securities trade (T) or very early on the next day (T+1) to meet the funding deadline for the security. This creates a severe operational bottleneck, particularly for trades executed late in the European or Asian day, which corresponds to the close of the US market.

> The move to T+1 compresses the FX lifecycle, forcing a near-instantaneous turnaround that strains traditional, sequential post-trade processes.

This compression effectively forces market participants into a difficult set of choices. They can attempt to execute the FX trade within a rapidly closing window after the US market closes, a period historically characterized by thin liquidity and wider spreads. Alternatively, they can pre-emptively execute the FX trade based on an estimated securities execution, introducing the risk of over- or under-hedging.

A third path involves forgoing the risk mitigation of CLS altogether and settling the FX transaction bilaterally on a same-day basis, which reintroduces the very [settlement risk](https://prime.greeks.live/area/settlement-risk/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) that CLS was created to eliminate. The viability of using CLS in a T+1 world is therefore a function of an institution’s ability to re-engineer its post-trade operational architecture to function within this dramatically condensed timeframe.

## What Is the Core Function of CLS?

CLS serves as the global financial market infrastructure for mitigating settlement risk in the FX market. Its primary mechanism, payment-versus-payment (PvP), acts as a sophisticated escrow service for 18 of the most actively traded currencies. By settling both sides of an FX trade simultaneously within its system, CLS eliminates the possibility of one party defaulting on its obligation after receiving payment from the other. This function is foundational to the stability of the global financial system, as it prevents a single counterparty failure from creating a cascade of defaults across the market.

Beyond risk mitigation, CLS also provides significant liquidity benefits through [multilateral netting](https://prime.greeks.live/area/multilateral-netting/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). It calculates the net funding required from each member across all their trades, drastically reducing the actual cash flows needed for settlement. On a typical day, members fund only about 1% of the total value of their payment instructions, optimizing capital efficiency across the system.

## How Does T+1 Disrupt the Standard FX Workflow?

The standard FX workflow for an international securities transaction has historically been sequential. An asset manager executes a securities trade, confirms the precise details and cash requirement, and then executes the corresponding FX trade. The T+1 settlement cycle shatters this linear process. The time between the confirmation of the US securities trade (often late in the US trading day) and the CLS cutoff time (midnight Central European Time) is now measured in hours, not days.

This compressed window presents a significant challenge for firms in different time zones. For an asset manager in Asia, the US market close occurs in the middle of their night, making real-time execution and processing extremely difficult without significant operational adjustments, such as establishing new trading locations or implementing “follow-the-sun” operational teams. This disruption forces a paradigm shift from a sequential to a parallel or even pre-emptive operational model, demanding a higher degree of automation, predictive analytics, and integration between securities and FX trading desks.

## Strategy

The accelerated settlement cycle for US securities necessitates a strategic recalibration for global [asset managers](https://prime.greeks.live/question/what-are-the-primary-challenges-for-asset-managers-in-complying-with-mifid-iis-transparency-regimes/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). The viability of continuing to use CLS hinges on adopting new operational frameworks that address the compressed timeline. The industry’s response has coalesced around several key strategies, each with a distinct risk-reward profile.

These approaches are not mutually exclusive and are often blended to suit an institution’s specific operational capabilities, risk tolerance, and trading patterns. The central strategic decision for firms is whether to absorb additional operational complexity and potential [execution cost](https://prime.greeks.live/area/execution-cost/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) to preserve the settlement risk protection of CLS, or to accept increased counterparty risk by settling outside the PvP mechanism.

CLS itself conducted a thorough analysis and, after surveying its members, made a critical strategic decision ▴ it would not extend its settlement deadlines to accommodate the T+1 shift. The rationale was that the impacted trade flow, while significant for the affected firms, represented a small fraction ▴ estimated at around 1% ▴ of CLS’s average daily settlement value of over $6.5 trillion. The systemic complexity, cost, and risk associated with altering the established global settlement timeline for all members were deemed to outweigh the benefits of accommodating this specific subset of trades. This decision placed the onus of adaptation squarely on the shoulders of market participants, particularly non-US asset managers and their custodian banks.

> The strategic response to T+1 is a trade-off between execution cost, operational complexity, and settlement risk.

Custodians have emerged as pivotal players in the new landscape, with many enhancing their process automation and adjusting their own internal cut-off times to help clients meet the CLS deadline. Their ability to provide flexible and efficient post-trade processing has become a key determinant of success for asset managers. The strategies being deployed reveal a market in adaptation, seeking equilibrium within the new temporal constraints.

## Adapting Execution and Settlement Models

Faced with the compressed timeline, firms are actively re-engineering their execution and settlement workflows. The primary strategic pathways include pre-funding, accelerated post-trade execution, and, as a last resort, [bilateral settlement](https://prime.greeks.live/area/bilateral-settlement/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). Each pathway requires a different combination of technology, operational process, and risk management.

One prominent strategy involves estimating the required FX at the time of the securities trade execution. Approximately 11% of asset managers surveyed by CLS indicated they plan to use this approach. This involves executing a primary FX trade based on the anticipated proceeds or cost of the securities transaction, followed by a smaller “true-up” trade once the final details are confirmed. This method ensures the bulk of the currency is secured in time for the CLS window but introduces basis risk and the operational overhead of a second transaction.

Another significant portion of asset managers (over 17%) intends to execute the FX transaction after the securities trade is confirmed, but on an accelerated T+1 basis. This requires highly efficient, automated post-trade processes to affirm the trade, calculate the FX requirement, and execute the currency trade within hours. This strategy’s success is highly dependent on liquidity in the late New York/early Asian trading window and the efficiency of the firm’s operational backbone.

The table below outlines the core strategic adaptations for managing FX settlement in a T+1 environment.

| Strategy | Operational Mechanism | Advantages | Disadvantages |
| --- | --- | --- | --- |
| FX Pre-Funding & Estimation | Execute an estimated FX trade at the time of the securities order, followed by a true-up trade upon confirmation. | Ensures timely submission to CLS, mitigates timing pressure. | Introduces execution risk on the true-up trade, requires more complex reconciliation. |
| Accelerated Post-Trade FX | Utilize automated workflows to confirm securities trade and execute the required FX in the compressed window before the CLS deadline. | Maintains a linear, confirmation-based workflow, reduces estimation errors. | High pressure on operational efficiency, exposed to poor liquidity and wider spreads in off-peak FX markets. |
| Bilateral T+0 Settlement | Execute the FX trade on the morning of T+1 and settle it directly with the counterparty, outside of CLS. | Avoids the CLS deadline pressure, accesses deeper morning liquidity. | Forfeits CLS’s PvP protection, reintroducing full principal counterparty risk. Increases operational burden of managing bilateral settlement. |
| Follow-the-Sun Operations | Establish trading and operations teams in different time zones to manage the FX lifecycle around the clock. | Provides 24-hour coverage to manage execution and settlement in real-time. | Significant cost and complexity in establishing and managing global operations. |

## How Does CLS Settlement Compare to Bilateral Settlement?

The decision to use CLS or settle bilaterally represents a fundamental choice about risk appetite. CLS provides a centralized, risk-controlled environment, while bilateral settlement offers flexibility at the cost of direct exposure to counterparty failure. The T+1 shift has forced many institutions to re-evaluate this trade-off.

The following table compares the key features of each settlement method.

| Feature | CLS Settlement | Bilateral Settlement |
| --- | --- | --- |
| Settlement Risk | Virtually eliminated through the payment-versus-payment (PvP) mechanism. | Full principal risk; one party can pay and not receive the corresponding currency if the counterparty defaults. |
| Liquidity Requirement | Dramatically reduced via multilateral netting; firms fund only their net position (approx. 1% of gross). | Gross funding required for every trade, leading to higher intraday liquidity demands. |
| Operational Efficiency | Standardized, automated processes for a large volume of trades. | Requires bespoke communication and confirmation for each counterparty, increasing operational overhead. |
| Timing Flexibility | Rigid submission deadlines (e.g. 00:00 CET for the initial pay-in schedule). | Flexible timing negotiated directly between counterparties. Can accommodate T+0 settlement. |

## Execution

The execution of FX trades in a T+1 securities environment is a matter of precise operational engineering. The theoretical strategies must translate into robust, automated, and resilient workflows. The initial data following the May 2024 transition to T+1 in North America indicates that the industry has, so far, adapted successfully.

CLS reported no decrease in average daily settlement values or volumes through its system; in fact, June 2024 was a record month with average daily values of $7.8 trillion. This suggests that firms have effectively implemented strategies to meet the compressed deadlines, avoiding a large-scale shift to riskier bilateral settlement.

The evidence of this adaptation is visible in the data. CLS observed a tangible change in the submission patterns of its members. There has been a slight increase in fund-related submission values beginning around 14:00 CET, with a more pronounced spike between 22:00 and 23:00 CET, just before the midnight deadline. This pattern suggests two execution tactics are at play.

The earlier increase may indicate that some funds are executing the FX component before the final confirmation of the securities trade, reflecting the pre-funding strategy. The later spike suggests that other firms, aided by enhanced automation and flexible custodians, are successfully processing and submitting their trades in the tight window after the US market close.

> Successful execution in the T+1 environment is defined by a firm’s investment in process automation and the strength of its partnership with its global custodian.

This successful navigation of the T+1 transition was not accidental. It is the result of significant investment in technology and process re-engineering across the industry. Custodians, in particular, have been praised for their proactive preparation and flexibility, which has been instrumental in allowing asset managers to adjust their workflows without abandoning the safety of CLS. The viability of CLS has been maintained because the ecosystem built around it has proven to be adaptable.

## Operational Playbook for T+1 FX Management

For an institutional trading desk, adapting to T+1 requires a detailed operational playbook. The focus is on speed, communication, and automation to compress a multi-day process into a matter of hours.

- **Pre-Trade Analytics and Estimation**

<li>
**Requirement Forecasting** ▴ Implement models to predict daily cash and FX needs based on anticipated trading activity. This allows for proactive liquidity management.

- 
**[Execution Cost Analysis](https://prime.greeks.live/area/execution-cost-analysis/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (ECA)** ▴ Develop ECA models for different times of the day, particularly for the illiquid window after the US close. This analysis informs the decision of whether to pre-fund or execute post-trade.

</li>
- **Execution Protocol Selection**

<li>
**Automated RFQ** ▴ Utilize Request for Quote (RFQ) systems that can automatically poll liquidity providers for the required FX pair as soon as the securities trade is confirmed.

- 
**Algorithmic Execution** ▴ Employ execution algorithms (e.g. TWAP or VWAP) for larger FX orders that need to be worked in the thin, late-session liquidity to minimize market impact.

</li>
- **Post-Trade Affirmation and Submission**

<li>
**[Straight-Through Processing](https://prime.greeks.live/area/straight-through-processing/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (STP)** ▴ The bedrock of the T+1 response. Ensure a fully automated link between the securities execution platform (OMS/EMS), the internal confirmation system, and the FX execution venue. Any manual intervention introduces unacceptable delay.

- 
**Custodian Communication Protocol** ▴ Establish real-time, automated communication links with custodian banks to confirm trade details and payment instructions. This ensures the custodian can meet its own deadlines for submitting to CLS.

</li>
- **Contingency and Risk Management**

<li>
**Bilateral Counterparty Review** ▴ For trades that may miss the CLS deadline, maintain a pre-vetted list of counterparties with whom bilateral settlement is deemed an acceptable risk. This includes having legal agreements (ISDAs) in place.

- 
**Failed Trade Protocol** ▴ Develop a clear, rapid-response protocol for handling failed FX trades to prevent a knock-on failure of the underlying securities transaction.

</li>

## Quantitative Impact and Market Behavior

The quantitative impact on CLS, while a concern, has been contained. The primary analysis from CLS identified that only about 1% of its average daily volume would be directly affected. This figure, approximately $65 billion, is substantial in absolute terms but manageable within the context of the entire market.

Further analysis suggested that roughly half of this amount, or about $33 billion, was at risk of moving outside CLS to be settled bilaterally. The market’s successful absorption of the T+1 transition, as evidenced by the stable-to-growing CLS volumes, indicates that a significant portion of this at-risk flow has found a way to remain within the CLS ecosystem through the operational and technological adaptations discussed.

The shift in submission timing provides the clearest quantitative signal of behavioral change. The increase in submissions between 22:00 and 23:00 CET directly correlates with the end of the US trading day and the last-minute rush to meet the CLS deadline. This demonstrates that the industry has successfully compressed its post-trade processing into this critical one-hour window, a feat made possible by technology.

## Reflection

The successful navigation of the T+1 transition is a powerful validation of the financial system’s adaptive capacity. It demonstrates that market structure is not a static edifice but a dynamic system that responds to external pressures through technological innovation and process re-engineering. The challenge has reinforced the symbiotic relationship between asset managers, their custodians, and critical market infrastructures like CLS. For the institutional principal, this episode offers a critical insight ▴ [operational resilience](https://prime.greeks.live/area/operational-resilience/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) and strategic advantage are derived from the quality of this interconnected architecture.

The focus now shifts from managing a one-time event to institutionalizing the lessons learned. The speed, automation, and communication protocols developed for T+1 are not temporary fixes; they are the new baseline for operational excellence. The question to consider is how this newly enhanced operational capability can be leveraged beyond settlement cycles to create a persistent competitive edge in execution, risk management, and capital efficiency across all asset classes.

                "text": "CLS serves as the global financial market infrastructure for mitigating settlement risk in the FX market. Its primary mechanism, payment-versus-payment (PvP), acts as a sophisticated escrow service for 18 of the most actively traded currencies. By settling both sides of an FX trade simultaneously within its system, CLS eliminates the possibility of one party defaulting on its obligation after receiving payment from the other. This function is foundational to the stability of the global financial system, as it prevents a single counterparty failure from creating a cascade of defaults across the market. Beyond risk mitigation, CLS also provides significant liquidity benefits through multilateral netting. It calculates the net funding required from each member across all their trades, drastically reducing the actual cash flows needed for settlement. On a typical day, members fund only about 1% of the total value of their payment instructions, optimizing capital efficiency across the system."

                "@type": "Answer",
                "text": "The standard FX workflow for an international securities transaction has historically been sequential. An asset manager executes a securities trade, confirms the precise details and cash requirement, and then executes the corresponding FX trade. The T+1 settlement cycle shatters this linear process. The time between the confirmation of the US securities trade (often late in the US trading day) and the CLS cutoff time (midnight Central European Time) is now measured in hours, not days. This compressed window presents a significant challenge for firms in different time zones. For an asset manager in Asia, the US market close occurs in the middle of their night, making real-time execution and processing extremely difficult without significant operational adjustments, such as establishing new trading locations or implementing \"follow-the-sun\" operational teams. This disruption forces a paradigm shift from a sequential to a parallel or even pre-emptive operational model, demanding a higher degree of automation, predictive analytics, and integration between securities and FX trading desks."

                "@type": "Answer",
                "text": "The decision to use CLS or settle bilaterally represents a fundamental choice about risk appetite. CLS provides a centralized, risk-controlled environment, while bilateral settlement offers flexibility at the cost of direct exposure to counterparty failure. The T+1 shift has forced many institutions to re-evaluate this trade-off."
