For decades, the settlement cycle in securities markets has been gradually shrinking as technology improved and regulators sought to reduce risk in financial markets. What once required five business days (T+5) now typically settles in two days (T+2) across most developed markets.

A brief history

Shortening settlement cycles has been a gradual but consistent trend in global capital markets. For much of the twentieth century, securities markets operated on a T+5 settlement cycle, meaning transactions settled five business days after the trade date. Improvements in technology and market infrastructure gradually enabled regulators to reduce this timeline. The United States shortened the cycle to T+3 in 1987, followed by T+2 in 2017, and ultimately transitioned to T+1 in May 2024. Interestingly, this change effectively reinstated the settlement cycle that existed before the Great Depression in 1929.

The immediate catalyst for the most recent change was the extreme market volatility observed during the COVID-19 pandemic, particularly during the so-called meme-stock trading boom. Increased volatility significantly raised the collateral that brokers needed to post between trade execution and settlement. This raised broader questions about why, in a highly digital trading environment, securities transactions still required two days to settle.

Despite the push for faster settlement, T+1 is currently considered the shortest operationally feasible cycle for most securities markets. Certain post-trade processes, particularly foreign exchange transactions and securities lending, still rely on a settlement delay. Moving further toward real-time or T+0 settlement would require more fundamental changes to market infrastructure and operational frameworks. And for that the industry isn’t ready yet.

Europe’s Path to T+1: Accelerating Securities Settlement Across the EU

Given the global nature of capital markets, international coordination of the implementation of T+1 is essential. The European transition follows earlier adoption in markets such as the United States, Canada, India and China, and is being coordinated with similar initiatives in the United Kingdom and Switzerland to avoid cross-border settlement mismatches.

The European Union started a feasibility study for the shift early 2025. In June 2025 the EU confirmed the transition and established a high-level roadmap for implementation, providing a framework for technical, operational and behavioral changes, with a target date set at 11 October 2027. The year 2026 will focus on active implementation, giving market participants ample time to upgrade systems, adjust operational workflows, and carry out comprehensive industry testing ahead of the go live.

What are the benefits?

The industry has been typically reluctant in implementing costly technical changes unless there is an immediate benefit and T+1 is no different, hence the importance of the European Commission driving this change. We believe longer-term benefits are, however, substantial:

Reduced collateral margins: clearing system members need to post margin with the Central Counterparty (CCP) and a shorter settlement cycle will reduce these margin requirements. As explained previously this was for the US market a key reason to make the move to T+1.

Alignment with other markets: increased adoption is self-reinforcing to avoid operational challenges and market fragmentation. This is why the US teamed up with Canada and Mexico in 2024 and now the European Commission is pursuing implementation in alignment with the UK and Switzerland.

Implementation will be a catalyst for further automation: the roll-out of T+1 can be used as justification for further investments in automation, which will bring long-term cost savings to the industry.

Improved market confidence: especially among retail investors a shortened settlement cycle will boost confidence in the technical underpinnings of the stock market.

And at what cost?

To make all this happen, there is first some work to be done:

Required changes to IT systems: obviously technical adaptations will have to be done in the trading and post-trading systems to enable the new settlement cycle.

Full review of operational processes: business processes will generally stay the same which limits the development and migration effort, but consequently what is done now in two days will need to be done in just a single day. Settlement confirmations will need to be done same-day and the turnaround of other supporting processes (like forex and stock lending) will have to be significantly sped up. Further automation and higher straight-through processing (STP) rates are essential to succeed and avoid late settlements.

Avoid an increase in settlement fails and related penalties: as under the EU Central Securities Depositories Regulation (CSDR) penalties for late settlement are levied. This is a challenge that was absent from the US implementation and if not managed properly this could quickly escalate into a costly headache for market participants.

What to do next?

With the transition confirmed in late 2025, the clock is now ticking for financial institutions. The challenge goes beyond regulatory compliance: processes that currently span two days will need to be completed within a single day. This will require higher levels of automation, greater operational efficiency, and more resilient processes to minimize settlement failures and avoid CSDR penalties.

Implementation support and testing

The shift to T+1 is not just a regulatory milestone – it is also an opportunity to modernize post-trade operations, increase automation, and strengthen straight-through processing. Preparing early will make the difference between a smooth transition and a costly operational challenge. DynaFin is ready to support institutions in making this transition successful. Over the past decade, banks have significantly transformed their client onboarding and reporting processes.

Much of that transformation was driven by regulations such as the Foreign Account Tax Compliance Act (FATCA) and the Common Reporting Standard (CRS).

For many institutions, these frameworks introduced a completely new operational reality: identifying tax residency, classifying entities, collecting documentation, and reporting financial information to tax authorities around the world.

But recently, another regulatory dynamic has started to attract increasing attention: initiatives coming from the Financial Crimes Enforcement Network (FinCEN).

And although these initiatives originate in the United States, their implications are increasingly relevant for international banks.

 

From tax transparency to financial transparency

While FATCA and CRS focus primarily on tax transparency, FinCEN’s mandate relates to financial crime prevention.

Acting under the authority of the U.S. Bank Secrecy Act, FinCEN plays a central role in the U.S. anti-money laundering framework. Its mission is to combat financial crime by strengthening AML controls and improving visibility over financial transactions and ownership structures.

Recent developments illustrate this approach. In particular, the implementation of beneficial ownership reporting requirements under the U.S. Corporate Transparency Act now requires certain legal entities to disclose information about their beneficial owners to U.S. authorities. The aim is to increase transparency around legal entities and make it easier to identify the individuals who ultimately own or control financial assets and corporate structures.

Although these initiatives originate in the United States, their implications extend beyond U.S. borders. European banks remain closely connected to the U.S. financial system through dollar-denominated transactions, correspondent banking relationships and clients holding investments or assets linked to U.S. markets.

As a result, transparency expectations related to ownership structures and financial flows increasingly extend international financial institutions.

 

Client data as the common denominator

Although FATCA, CRS and FinCEN serve different regulatory purposes, they rely on the same foundation: client data.

Banks need to be able to consistently identify:

  • tax residency
  • entity classifications
  • beneficial owners
  • ownership and control structures.

In practice, this increasingly requires coordination between teams across tax reporting, KYC, AML and financial crime compliance.

What used to be distinct regulatory exercises is gradually becoming a broader challenge around client data governance.

 

A compliance topic… but also a data architecture challenge

For many financial institutions, the complexity today is not necessarily the regulation itself.

It is the ability to build systems and processes capable of supporting several transparency regimes simultaneously.

This includes improving:

  • client data models
  • beneficial ownership identification
  • consistency between KYC, AML and tax reporting frameworks
  • governance of client information.

In that sense, regulatory transparency is increasingly becoming a data architecture challenge.

 

Looking ahead

Regulatory transparency is unlikely to slow down in the coming years.

If anything, authorities are seeking greater visibility over global financial activity.

In other words, the real challenge for banks is no longer FATCA, CRS or FinCEN individually.

It is building a client data architecture capable of supporting all of them simultaneously.

And for many institutions, that may well become the next major regulatory transformation.
