Risk management is one of those disciplines that looks straightforward in calm markets and reveals its true complexity when conditions turn — and few people understand that better than Toby Watson.
Managing risk well is not simply a matter of following rules or running models. It requires a deep, practical familiarity with how markets behave under pressure — familiarity that can only be built through experience of real stress events, not just theoretical frameworks. Many investors discover the limits of their risk management approach only when it is too late to adjust. Toby Watson, who spent close to two decades working at the sharpest end of structured finance, developed that kind of hard-won understanding across some of the most demanding market environments of recent times.
During Toby Watson’s time at Goldman Sachs, where he worked for nearly 17 years across structured credit trading, principal funding, and global infrastructure financing, risk management was not a peripheral concern, but a central discipline embedded in every investment decision. Toby Watson became a Partner at Goldman Sachs in 2012 and left in 2017, subsequently joining Rampart Capital as a Partner in 2020. Rampart Capital is an independent London-based investment office providing bespoke investment management to wealthy individuals and families. The firm’s investment philosophy places risk management at the heart of its portfolio construction process, reflecting the principles that Toby Watson and his colleagues developed across decades of institutional investment experience. He also served as voluntary Chairman of Excalibur Academies Trust from 2018 until early 2026.
Structured Finance as a Training Ground for Risk Thinking
Structured finance occupies a particular place in the history of modern risk management. The instruments at the heart of the 2008 financial crisis were, in many cases, structured products whose risk profiles were imperfectly understood even by sophisticated market participants. Working in that environment, as Toby Watson did during his years at Goldman Sachs, required developing a genuine rather than superficial understanding of how risk behaves when embedded in layered, interconnected structures.
Structured finance, at its best, is a powerful tool for allocating risk efficiently. At its worst, it can obscure risk rather than manage it, packaging complexity in ways that make underlying exposures difficult to identify until they materialise. Having worked at Goldman Sachs through periods when both dynamics were in play, Toby Watson developed a clear-eyed view of the difference between genuine risk management and the appearance of it.
The most important practical lessons from that environment include:
- Treating liquidity as a first-order consideration — the ability to exit or adjust positions under stress is often more valuable than optimising returns in normal conditions
- Distinguishing between risk that is being taken deliberately and risk that is present but not yet visible — the latter is almost always more dangerous
- Stress-testing assumptions rather than validating them — the question is not whether a model works under normal conditions, but whether its failure modes are understood
- Maintaining scepticism about complexity — instruments that are difficult to analyse clearly often conceal risks that become apparent only under pressure
What does structured finance experience teach you that other areas of finance do not?
Working in structured finance requires engaging with risk at a level of granularity that many other areas of investment do not demand. What Toby Watson observed at Goldman Sachs was that the most dangerous risks were often not the ones explicitly modelled, but those that emerged from interactions between assumptions — particularly under stress conditions the models had not anticipated. That insight shapes a risk management philosophy that treats model outputs as inputs to judgement, not substitutes for it.
From Theory to Practice: How Risk Management Actually Works
There is a gap between risk management as it appears in textbooks and as it functions in real institutions under pressure. Models are useful — they provide structure, force discipline, and make assumptions explicit. But they are built on historical data and theoretical relationships that may not hold in the scenarios that matter most.
The practical reality of risk management, as Toby Watson experienced it at Goldman Sachs, involved constant interrogation of model assumptions, scenario analysis that went beyond standard frameworks, and a clear recognition that liquidity risk was often the most significant and least adequately captured dimension of portfolio risk. Those habits of mind translate directly into the approach that informs Rampart Capital’s investment process, which embeds risk management throughout portfolio construction rather than treating it as a separate layer applied after investment decisions have been made. For Toby Watson that integration of risk thinking into every stage of the investment process is not a stylistic preference but a fundamental principle.
The Principles That Endure Across Market Cycles
Having worked across multiple market cycles — through the build-up to 2008, the crisis itself, and the long recovery that followed — Toby Watson developed risk management principles that have proved durable across very different environments. The discipline that Toby Watson built at Goldman Sachs was, in part, a discipline of resistance: asking uncomfortable questions even when the answers were inconvenient, and taking seriously the possibility that the consensus view of a risk was wrong.
When Models Fail: The Human Element in Risk Management
One of the more enduring lessons from Toby Watson’s career in structured finance is that risk management ultimately depends on judgement as much as process. Models can be gamed, assumptions optimised to produce comfortable outputs, and institutional pressures can create incentives to understate risk.
That disposition — sceptical, rigorous, and attentive to what models might be missing — cannot be acquired from reading. It is built through experience of markets that behave in ways nobody predicted. The qualities that characterise sound risk management in practice include:
- Intellectual honesty about the limits of any analytical framework, however sophisticated
- A consistent focus on downside scenarios, not just expected outcomes
- The willingness to reduce exposure when uncertainty is genuinely high, even at the cost of near-term returns
- An understanding that risk management is not a constraint on good investing but a precondition for it
For Toby Watson, those principles were not learned in a classroom. They were shaped by close to two decades at the centre of one of the most complex and demanding areas of global finance — and they continue to inform his approach to investment management at Rampart Capital today.
