In this episode of Caplin Connects, John Ashworth, CEO of Caplin, is joined by Bob Tull, Global Head of Fixed Income, Currencies and Commodities at Fifth Third Bank. With a career spanning multiple institutions, market cycles, and structural shifts in banking, Bob has moved from execution trading to senior leadership without losing sight of what pressure feels like on the front line.
What emerges from the conversation is not a narrative about disruption or innovation for its own sake, but a measured examination of leadership, judgment and relationships in markets that have become faster, quieter and more automated. Technology has changed how business is done, but Bob is clear that it has not changed the underlying responsibilities of those who lead, trade or advise clients.
Having entered banking in the mid-1980s and spent decades across trading, sales and leadership, Bob’s perspective on financial markets is shaped not by theory or by any single role, but by an accumulation of lived experiences; moments of stress, change and recalibration that have revealed what really matters inside financial institutions. This is critical because many pressures facing today’s firms are not new; they arrive in different guises, amplified by technology, speed and scale.
What changes over time is not the existence of stress, volatility or uncertainty, but how organisations respond to them. Bob’s reflections consistently return to this point. Tools evolve, market structure shifts, but leadership still shows up most clearly when conditions are uncomfortable.
One of the most consequential transitions in Bob’s career was moving out of a front-line sales and trading role into leadership. He describes this as the hardest step, not because it required less engagement, but because it required a different kind of awareness.
Leadership, in his view, creates distance from the immediacy of markets while simultaneously increasing responsibility for people experiencing that immediacy every day. The challenge is to focus on strategy, development and culture without losing empathy for the pressures faced by traders and salespeople making decisions in real time.
That empathy is grounded in memory; remembering what it feels like to land a first client, to miss a trade, or to make “a tough call in a bad market or a great call in a tough market”. Effective leadership, for Bob, depends on retaining that perspective even as roles become more removed from execution.
Culture features prominently in Bob’s thinking, but not as a set of values displayed on walls. He frames it as something experienced daily in the room; shaped by incentives, behaviour and how mistakes are handled.
Mistakes, he argues, are inevitable in a business as complex and fast-moving as markets. The test is not whether errors occur, but how institutions respond to them. His advice to younger professionals is direct: “You’re going to make mistakes… own it… and don’t get yourself so wound up in that mistake that you wind up paralysing yourself moving forward.”
That approach scales upward. Organisations that punish errors indiscriminately tend to create hesitation and a lack of transparency; those that distinguish between learning mistakes and ethical breaches build resilience.

Ethics, in Bob’s view, are non-negotiable. “Just be ethical… be honest… don’t shade the truth one way or the other.” In increasingly automated environments, where accountability can become diffused, that clarity becomes more important rather than less.
Asked about the biggest changes he has seen in markets, Bob points first to electronification. The shift from voice-based trading to point-and-click execution has transformed workflows, market access and efficiency. Yet he is candid about what has been lost along the way.
Trading floors no longer carry the same energy they once did. The disappearance of brokers, squawk boxes and constant voice interaction has altered not just mechanics, but atmosphere. While some asset classes still retain more voice-driven characteristics, Bob sees this as temporary; electronification continues to advance.
His observation is not nostalgic. Energy, in this context, is linked to situational awareness; the informal signals and shared understanding that emerge when people interact more intensely. As markets become quieter on the surface, leaders must work harder to ensure judgment, context and communication are not diluted.
Bob’s views on client relationships are shaped by periods of stress rather than stability. “Clients remember how you behave when things aren’t straightforward. That’s when trust is really built or lost.” Reflecting on recent bank failures, he avoids generalisations and focuses instead on fundamentals. Liquidity matters, but communication and trust matter just as much.
“Relationships have to be there at good times and bad times,” he says. They cannot be “set and forget” activities. Maintaining them requires regular, often unremarkable effort; picking up the phone, checking in, understanding what clients are experiencing before problems escalate.
For regional and super-regional banks, this becomes a defining differentiator. Their value proposition lies in offering a breadth of services close to that of larger institutions, combined with a level of relationship depth that larger banks often struggle to maintain. Clients may not see internal policies or balance-sheet mechanics, but they do see people, platforms and the quality of dialogue.
Trust, in this sense, is cumulative. It is built long before it is tested, and when pressure arrives, it either holds or it does not.
Over the course of his career, Bob has observed clients become significantly more attuned to markets. Access to information, global connectivity and internal analytics have raised baseline understanding across corporates and institutions alike.
This does not diminish the role of banks; it reshapes it. Clients are less interested in being told what to do and more interested in understanding implications. They want context around volatility, geopolitics, commodities or rates, and how these forces intersect with their own business models.
Much of the work, as Bob describes it, is informational rather than transactional. Regular market updates, roundtables and direct conversations help clients navigate uncertainty, even when definitive answers do not yet exist. In an environment where “any given tweet on any given day will change the market perception”, helping clients interpret noise becomes as valuable as executing trades.
As markets digitise further, Bob is careful not to frame automation as an end in itself. Post-trade processes, he notes, should be fully automated wherever possible; efficiency and accuracy are expected, not optional. Institutions that have not modernised here are already behind.
Pre-trade and execution, however, remain more nuanced. Certain products and structures resist full automation because they embed judgment, bespoke risk and client-specific context. Chat-based workflows have replaced much of the phone, but price discovery and structuring still rely on human interaction.

Looking ahead, Bob sees technologies such as stablecoins and blockchain as inevitable forces, particularly in cross-border payments and settlement. Yet he emphasises uncertainty over timing and form. “It’s here… you can’t turn a blind eye to it,” but operational, credit and safekeeping questions remain unresolved.
Across all of this, accountability does not disappear. “Technology doesn’t remove responsibility. Someone still has to own the decision and the outcome.” Automation may execute, but responsibility still sits with people.
Bob’s reflections consistently highlight the value of experience; not as nostalgia, but as a foundation for sound judgment. Markets evolve and products change, but human behaviour under pressure follows familiar patterns that experience helps leaders recognise early.
This is why he places such emphasis on learning and staying humble. Even after decades in the industry, he insists, “This business takes a long time to learn. I’ve seen young folks who are very bright, after six, eight, nine months saying, ‘I’ve got it.’ I’ve been in the business for 35 years. I still don’t have it because it’s ever changing.” That mindset underpins his advice to younger professionals; knowledge of markets never reaches a final state, and effectiveness comes down to “just being really someone who enjoys learning.”
In banks facing rapid technological change, institutional memory becomes a form of capital. It helps distinguish signal from noise, supports decision-making during periods of stress, and anchors ethical behaviour in increasingly automated environments.
FINAL THOUGHTS
As markets become more automated, more connected and more complex, Bob’s perspective remains grounded in people; how they behave, how they lead, and how they relate to one another over time. Technology alters the surface of markets, but it does not remove the need for judgment, trust or accountability.
Leadership, in this context, is less about predicting the future than about creating organisations capable of navigating it. That work is ongoing, rarely visible, and never finished; much like the relationships and careers that sustain the market itself.
