Litigation risk is moving through the transaction chain

 

Focus is shifting beyond trading desks into custody, settlement and intermediary roles

Recent financial litigation has focused on trading activity but that focus is beginning to shift.

Much of the attention in recent cases has been on trading desks and transaction origination. As matters develop, scrutiny is beginning to move further along the transaction chain. It is reaching brokers and custodians and extending into those involved in securities lending, clearing and administration. Many of these firms operated in line with established market practice. They are now being assessed through the lens of hindsight. In this piece, we consider how and why that shift is occurring, where risk is likely to emerge next and why early and technically grounded analysis can materially affect how these matters are understood and resolved.

The next phase of financial litigation: from trading desks to the transaction chain

In earlier pieces, I have set out the role of expert evidence in financial services disputes. I have also addressed the importance of understanding market practice and valuation and the benefit of involving experts at an early stage.

Please refer to the relevant pieces below:

The Challenge of Historical Reconstruction

Synthetic Exposure and the Next Regulatory Phase

A consistent theme across those discussions has been the gap between how transactions were understood at the time and how they are later reconstructed in litigation.

What is now becoming clearer is that the focus of that reconstruction is beginning to shift.

Historically, enforcement and litigation activity has concentrated on trading desks and those directly responsible for originating transactions. That was a natural starting point because individuals and institutions closest to the trading activity are the most visible and the easiest to pursue.

However, as previously discussed, complex financial transactions do not exist in isolation. They sit within a broader structure that depends on a range of intermediaries and service providers. Each plays a defined role in allowing a transaction to be executed, documented and ultimately settled.

As matters develop, attention inevitably moves along that structure.

This is already evident in cross-border dividend arbitrage and withholding tax cases. What begins as a focus on trading activity often develops into a more detailed examination of how transactions were supported and processed. That includes custody arrangements, the operation of stock lending and the mechanics of settlement. It also brings into focus the role of intermediaries and how their involvement is later characterised.

A similar pattern is likely to develop more widely in disputes involving derivatives, structured products and financing arrangements.

In practice, many firms operating within the transaction chain did so in accordance with established market conventions. Pricing reflected prevailing conditions at the time. Documentation followed recognised frameworks. Responsibilities were allocated across counterparties in a way that was understood within the market.

In litigation, those same arrangements are revisited with the benefit of hindsight. The emphasis often shifts toward outcomes rather than process. This can lead to conclusions that do not fully reflect how the market functioned or what participants could reasonably have known.

It is also common to see an assumption that each participant had visibility of the wider transaction structure. In reality, firms typically operated within defined roles, with limited access to information beyond their immediate function.

Understanding those roles and the constraints within which firms operated is central to any fair assessment of conduct.

This is where the themes discussed in earlier pieces become increasingly relevant.

The issue is not simply one of describing events after the fact. It is about explaining how markets operated and how pricing and risk were understood at the time. It also requires a clear view of what would have been regarded as normal or reasonable in the context of prevailing market conditions. That includes an understanding of how different parts of the transaction chain interacted and where responsibility genuinely sat.

In many cases, the key questions are technical rather than legal. They arise from how market practice is interpreted, how valuation is approached and how the economic substance of transactions is understood. Without a clear and contemporaneous framework, there is a risk that analysis becomes simplified or shaped by hindsight.

As the focus of litigation moves beyond trading desks, firms that have not historically been at the centre of enforcement activity may find themselves drawn into complex and often multi-jurisdictional disputes. These matters frequently involve large volumes of historic transactions and documentation that is not always complete. They also involve legal frameworks that differ across jurisdictions.

In that environment, early clarity on the technical and market context can materially affect how a matter develops, ensuring the underlying activity is properly understood before positions become fixed and narratives become difficult to challenge.

The shift from trading desks to the wider transaction chain reflects the structure of modern financial markets. Risk, responsibility and information are distributed across multiple participants. As that shift continues, the need for clear and technically grounded explanation of market practice will only increase.

For firms operating within that chain, it may be worth considering at an early stage how historic activity would be explained if subjected to detailed scrutiny. That includes whether the assumptions around pricing, roles and responsibilities can be clearly articulated and supported.

Where that is uncertain, a short and focused review can often provide clarity and help frame the issues before they become more difficult to address.

At Objectivus, this forms a central part of our expert witness and advisory work. We are typically engaged to analyse trading activity and valuation as well as settlement mechanics and governance in the context of disputes or anticipated challenges. This work is often cross-border in nature.

In many cases, that involvement begins before formal proceedings. An early and independent assessment of market practice and technical issues can assist in shaping how a matter is approached.

If you are considering how a particular set of transactions or structures may be viewed in a contentious setting, we would be happy to provide an initial and focused view.
