## Concept

The transition to a T+1 settlement cycle represents a fundamental rewiring of the temporal architecture of [financial markets](https://prime.greeks.live/area/financial-markets/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). For [ETF market makers](https://prime.greeks.live/area/etf-market-makers/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) and custodians, this compression of the settlement timeline from two business days to one is a paradigm shift that recalibrates the very nature of risk. The core of this alteration lies in the accelerated timeline for reconciling trades, a process that exposes both market makers and custodians to a new spectrum of operational, liquidity, and counterparty risks.

The previous T+2 framework, while not without its own challenges, afforded a degree of temporal flexibility that has now been excised from the system. This new reality demands a complete re-evaluation of established workflows and risk management protocols.

> The T+1 settlement cycle fundamentally alters risk for ETF market makers and custodians by compressing the time available to manage operational processes, secure funding, and mitigate counterparty exposure.

## The New Velocity of Risk

The primary way in which the T+1 shift alters [risk parameters](https://prime.greeks.live/area/risk-parameters/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) is by increasing the velocity of risk itself. In a T+2 environment, market participants had a full day to identify and rectify errors, manage funding requirements, and recall loaned securities. This temporal buffer has been all but eliminated.

For ETF [market makers](https://prime.greeks.live/area/market-makers/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), the accelerated timeline for creation and redemption orders means that any delays in the delivery of the [underlying securities](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) can result in settlement fails, which carry significant financial penalties. Custodians, in turn, face a compressed window to affirm trades, process corporate actions, and manage cash and securities movements, all of which amplify the potential for operational errors and liquidity shortfalls.

## What Are the Immediate Consequences of a Settlement Failure?

A settlement failure in a T+1 environment has immediate and cascading consequences. For an [ETF market](https://prime.greeks.live/area/etf-market/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) maker, a failure to deliver the underlying securities for a creation order can result in a financial penalty from the clearinghouse. The market maker may also be forced to borrow the securities at a high cost to fulfill their obligation.

For a custodian, a settlement failure can lead to a breach of contract with their client, as well as reputational damage. In a worst-case scenario, a series of settlement failures could trigger a liquidity crisis, with systemic implications for the broader market.

## The Interplay of Liquidity and Operational Risk

The T+1 shift creates a tighter coupling between liquidity risk and [operational risk](https://prime.greeks.live/area/operational-risk/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). Any inefficiency in the operational workflow can have an immediate impact on a firm’s liquidity position. For example, a delay in [trade affirmation](https://prime.greeks.live/area/trade-affirmation/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) can prevent a custodian from releasing the necessary cash or securities for settlement, leading to a funding shortfall. Similarly, a market maker who is unable to efficiently source the underlying securities for an ETF creation order may be forced to tap into their own capital reserves to complete the trade, tying up liquidity that could be used for other purposes.

This heightened interplay between liquidity and operational risk demands a more integrated approach to risk management. Firms can no longer afford to view these two risk categories in isolation. Instead, they must develop a holistic framework that considers the potential for operational failures to trigger liquidity events, and vice versa. This requires a deep understanding of the end-to-end trade lifecycle, as well as the ability to model the potential impact of various stress scenarios on both operational and liquidity metrics.

## Strategy

The strategic imperative for ETF market makers and custodians in a T+1 environment is to re-architect their operational and risk management frameworks to accommodate the [compressed settlement cycle](https://prime.greeks.live/question/what-are-the-primary-operational-risks-when-submitting-a-portfolio-for-a-compression-cycle/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). This requires a multi-pronged approach that encompasses process automation, enhanced communication protocols, and a more dynamic approach to liquidity and [collateral management](https://prime.greeks.live/area/collateral-management/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). The overarching goal is to create a more resilient and efficient operating model that can withstand the increased velocity and complexity of the T+1 world.

> A successful transition to T+1 requires a strategic realignment of operational workflows, with a focus on automation, real-time communication, and proactive liquidity management.

## Automating the Trade Lifecycle

Automation is the cornerstone of any effective T+1 strategy. The manual processes and batch-based workflows that were sufficient in a T+2 environment are no longer viable. Firms must invest in technology that can automate the entire trade lifecycle, from trade capture and affirmation to settlement and reconciliation. This includes the implementation of [straight-through processing](https://prime.greeks.live/area/straight-through-processing/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (STP) for trade matching, as well as the use of sophisticated algorithms to optimize collateral and funding allocation.

The benefits of automation are twofold. First, it reduces the risk of operational errors by eliminating the need for manual intervention. Second, it frees up human resources to focus on more value-added activities, such as risk analysis and exception management. By automating the routine tasks associated with trade processing, firms can create a more efficient and scalable operating model that is better equipped to handle the demands of the T+1 [settlement cycle](https://prime.greeks.live/area/settlement-cycle/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite).

## How Does Automation Impact the Role of the Custodian?

Automation will fundamentally reshape the role of the custodian. In a T+1 world, [custodians](https://prime.greeks.live/area/custodians/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) will need to move beyond their traditional role as a record-keeper and become a more strategic partner to [their clients](https://prime.greeks.live/question/how-does-a-market-makers-inventory-position-influence-the-quotes-it-provides-to-clients/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). This will require a greater focus on providing real-time data and analytics, as well as proactive advice on how to navigate the complexities of the new settlement environment. Custodians who can successfully make this transition will be well-positioned to thrive in the T+1 era.

One granular arm signifies aggregated liquidity pools and latent liquidity](https://options.greeks.live/wp-content/uploads/2025/07/institutional-rfq-engine-microstructure-for-atomic-settlement.jpg)

## Enhancing Communication and Collaboration

In addition to automation, enhanced communication and collaboration are critical to success in a T+1 environment. The compressed settlement cycle leaves little room for error, which means that all parties to a trade must be in constant communication to ensure that any issues are identified and resolved in a timely manner. This requires the establishment of clear communication protocols, as well as the use of technology that can facilitate real-time information sharing.

For ETF market makers, this means working more closely with authorized participants (APs) to ensure that creation and redemption orders are submitted in a timely and accurate manner. For custodians, it means collaborating more closely with their clients to ensure that trade instructions are affirmed and settled on time. By fostering a culture of open communication and collaboration, firms can reduce the risk of settlement fails and create a more efficient and transparent market.

## A Dynamic Approach to Liquidity and Collateral Management

The T+1 shift also requires a more [dynamic approach](https://prime.greeks.live/question/what-are-the-strategic-trade-offs-between-the-standardised-approach-and-the-internal-model-approach-under-frtb/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) to liquidity and collateral management. In a T+2 world, firms had more time to manage their funding needs and optimize their collateral usage. In a T+1 world, these processes must be managed in real-time. This requires the use of sophisticated liquidity and collateral management systems that can provide a consolidated view of a firm’s positions and exposures across all asset classes and geographies.

By taking a more dynamic approach to liquidity and collateral management, firms can reduce their funding costs, optimize their use of capital, and minimize their exposure to market and [counterparty risk](https://prime.greeks.live/area/counterparty-risk/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). This will be a key differentiator for firms in the T+1 environment, as those who are able to effectively manage their liquidity and collateral will be better positioned to compete and grow their business.

## Execution

The execution of a successful T+1 transition requires a detailed and disciplined approach. Firms must conduct a thorough assessment of their existing processes and systems to identify any gaps or weaknesses that could be exposed by the compressed settlement cycle. They must also develop a comprehensive implementation plan that outlines the specific steps they will take to upgrade their technology, retrain their staff, and communicate with their clients and counterparties. This is a complex undertaking that requires a significant investment of time and resources, but it is essential for any firm that wants to remain competitive in the new T+1 world.

> A successful T+1 implementation hinges on a meticulous execution plan that addresses technology upgrades, process re-engineering, and stakeholder communication.

## The T+1 Implementation Roadmap

A typical T+1 implementation roadmap will consist of several key phases. The first phase is assessment and planning, [during which](https://prime.greeks.live/question/what-are-the-primary-mechanisms-through-which-post-trade-data-influences-lit-market-liquidity/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) the firm will conduct a detailed analysis of its current state and develop a high-level plan for the transition. The second phase is design and development, during which the firm will design and build the new processes and systems that will be required to support [T+1 settlement](https://prime.greeks.live/area/t1-settlement/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite).

The third phase is testing and deployment, during which the firm will test the new processes and systems to ensure that they are working as expected and then deploy them into the production environment. The final phase is post-implementation support, during which the firm will provide ongoing support to its staff and clients to ensure a smooth transition to the new T+1 world.

## What Are the Key Milestones in a T+1 Implementation Project?

The key milestones in a T+1 implementation project will vary depending on the size and complexity of the firm, but they will typically include the following:

- **Project Kick-off** ▴ The official start of the project, during which the project team is assembled and the project goals and objectives are defined.

- **Requirements Gathering** ▴ The process of gathering and documenting the business and technical requirements for the new T+1 processes and systems.

- **System Design** ▴ The process of designing the new T+1 processes and systems, including the development of detailed process flows and [system architecture](https://prime.greeks.live/area/system-architecture/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) diagrams.

- **System Development** ▴ The process of building and configuring the new T+1 processes and systems.

- **Testing** ▴ The process of testing the new T+1 processes and systems to ensure that they are working as expected.

- **Deployment** ▴ The process of deploying the new T+1 processes and systems into the production environment.

- **Post-implementation Review** ▴ A review of the project to identify any lessons learned and to ensure that the project has met its goals and objectives.

## Technology and System Architecture

The technology and system architecture that underpins a firm’s T+1 strategy is critical to its success. Firms must invest in a modern, flexible, and scalable technology platform that can support the real-time processing and data analytics that are required in a T+1 environment. This includes the implementation of a robust order management system (OMS), a sophisticated collateral and liquidity management system, and a powerful data analytics platform.

The system architecture should be designed to support a high degree of automation and straight-through processing. It should also be able to integrate seamlessly with the systems of the firm’s clients, counterparties, and service providers. By investing in the right technology and system architecture, firms can create a more efficient, resilient, and competitive operating model that is well-positioned for the future.

## Quantitative Analysis of T+1 Impact

The move to T+1 is expected to have a significant quantitative impact on the costs and risks associated with ETF trading. On the one hand, the shorter settlement cycle will reduce the amount of time that a firm is exposed to counterparty and market risk, which should lead to a reduction in the amount of collateral that is required to be posted with clearinghouses. On the other hand, the compressed timeline for trade processing and funding will likely lead to an increase in operational costs, at least in the short term, as firms invest in new technology and retrain their staff.

The net impact of these changes will vary depending on the specific circumstances of each firm. However, it is clear that the move to T+1 will require a significant investment in technology and process re-engineering. Firms that are able to make this investment will be well-positioned to reap the benefits of the new settlement environment, while those that are not may find themselves at a competitive disadvantage.

## Reflection

The transition to a T+1 settlement cycle is more than just a technical adjustment to the plumbing of the financial markets. It is a catalyst for a fundamental re-evaluation of the way that firms manage risk, deploy capital, and interact with their clients and counterparties. As you navigate this new landscape, it is worth considering how your own operational framework can be adapted to not only mitigate the new risks that have emerged, but also to capitalize on the new opportunities that have been created. The firms that will thrive in the T+1 era will be those that view this transition not as a challenge to be overcome, but as an opportunity to build a more resilient, efficient, and competitive business.

For an ETF market maker, a failure to deliver the underlying securities for a creation order can result in a financial penalty from the clearinghouse. The market maker may also be forced to borrow the securities at a high cost to fulfill their obligation. For a custodian, a settlement failure can lead to a breach of contract with their client, as well as reputational damage. In a worst-case scenario, a series of settlement failures could trigger a liquidity crisis, with systemic implications for the broader market."
