Wall Street has implemented the fastest settlement of trades in about a century, reverting to the same-day settlement last seen in the 1920s. The change, driven by new SEC rules, aims to reduce financial risk but raises concerns about potential issues, such as international investors struggling to source dollars quickly. The industry has prepared extensively, with firms adjusting operations and staffing to handle the transition, although challenges are expected during the adjustment period.

The Securities and Exchange Commission (SEC) implemented the T+1 settlement system for share trades primarily to reduce risks in the financial system6. By halving the settlement time—from two days to just one—after a trade is executed, the new system aims to minimize the period during which a trade could fail due to various issues such as counterparty defaults or other operational problems6. This change is intended to enhance the overall efficiency and stability of the market by reducing the time frame for potential exposure to financial risks. Additionally, the move aligns with technological advancements and the increased pace of trading, supporting a more resilient and timely market infrastructure.

Challenges for International Investors
The transition to a T+1 settlement cycle for US securities presents several challenges for international investors, particularly in the context of sourcing US dollars to fund transactions. Under the new rules, the settlement period for trades is reduced from two days (T+2) to just one day (T+1). This significant reduction in the settlement time means that international investors will have a much shorter window to secure the necessary US dollars.
Currency and Liquidity Issues
Traditionally, currency trades, including those involving US dollars, settle in two days (T+2). With the US moving to T+1 for securities transactions, there is a misalignment between the settlement of currency trades and securities trades. This misalignment could create liquidity challenges, especially toward the end of the FX trading day, which is typically marked by lower liquidity levels. Investors will need to plan meticulously to ensure they have access to US dollars within the constrained timeframe, potentially just a few hours, to meet the T+1 deadline.
Adjustments and Market Response
Over time, it is anticipated that the market will adjust to these changes. Liquidity is expected to improve as market participants adapt to the new settlement norms2. However, the initial phase of this transition may see turbulence as international investors and financial institutions recalibrate their operations and strategies to comply with the accelerated settlement cycle. This period of adjustment is crucial for maintaining market stability and ensuring that all participants can meet their transactional obligations under the new system.
