Adapting Through Change: Keith Hill on Technology, Markets and Career Growth

Introduction

In this episode of Caplin Connects, John Ashworth, CEO of Caplin, speaks with Keith Hill, an industry veteran whose career traces almost the entire arc of electronic foreign exchange. Keith arrived in financial markets as an unlikely candidate, a medieval and modern languages graduate from Oxford with no background in numbers, at a moment when the City was being reshaped by deregulation and the approach of Big Bang.From a fixed income desk at Goldman Sachs, through JP Morgan and a posting to emerging markets in Mexico and New York, Keith moved into the technology that would go on to redefine the market he had learned by voice. He was present at the creation and growth of the multi-dealer platforms Currenex, Atriax and FXall, before returning to the banking side at Société Générale and later joining Caplin's Advisory Board. What emerges is not a catalogue of firms and dates, but a practitioner's account of how markets change, why they change, and what a long career teaches about navigating that change deliberately.

A Career Built on Deliberate Discomfort

Keith is candid that his entry into finance owed a good deal to timing and to a refusal to compete on ground he could not win. Surrounded at interview by candidates with doctorates in STEM subjects, he leaned instead on what he had: the experience of winding down his late father's struggling chain of record shops while still a student, and a summer spent shepherding American tourists around Europe, which doubled as an informal lesson in foreign exchange and margin. That difference, rather than any technical pedigree, is what persuaded Goldman Sachs to take a chance on him.

The same instinct shaped the decisions that followed. Each significant move, from fixed income to foreign exchange, from London to Mexico to New York, and finally from a secure, well-paid bank role into a dot-com startup with a wife and three children to support, involved choosing discomfort over stability. Keith frames this not as recklessness but as method."If an opportunity comes up, take it. You can be too comfortable."By the close of the conversation that method has hardened into explicit advice for the next generation, built on four elements: understand the business, empathise with the people and clients in it, embrace change, and always have a plan. He is unsentimental about mistakes, recalling the guidance of a former JP Morgan manager, Nick Rodin, that "we expect you to make mistakes. We don't expect you to make the same mistake too many times." Intellectual curiosity sits at the top of his list, on the grounds that no one ever finishes learning this business.

When Invention Becomes the Mother of Necessity

‍

A rich thread in the discussion is how technology actually takes hold in markets. Keith's account inverts the familiar adage. Necessity does not always drive invention; often invention creates its own necessity. Once a tool exists and achieves the status of a market standard, everyone is obliged to have it, whether they rate it or not.His example is the option pricing system Fenix, the business he and colleagues later acquired. Its inventor gave the software to the brokers, establishing it as the reference point the whole market quoted from. The commercial model was as deliberate as the distribution. The first licence, Keith recalls, was sold to a bank for a hundred dollars, with the price doubling on each subsequent sale until it met genuine resistance, at which point it held. There were no salespeople. It was, in his words, a classic example of viral distribution, with the price set precisely at the point where buyers stopped pushing back.

Bloomberg followed the same logic. Its strength lay in data and analysis that let users see what was cheap and what was dear, and once enough of the market depended on it, the terminal became unavoidable even where its interface was forbidding. The deeper point Keith and John draw out is that transparency itself creates liquidity. Tier-two and tier-three banks adopted these systems not because they trusted the pricing above their own, but because they needed to know where everyone else was making and taking prices.

Transparency and the End of the Arbitrary Markup

If transparency built liquidity, it also dismantled an older way of making money. Keith is clear eyed about how pricing worked before electronic distribution, when margin was a matter of judgement and, often, of guesswork."If the same client had asked two salesmen for an identical price, they would get two different prices, because the salesman's job was to read the client and judge the appropriate margin for that size of trade on that occasion."Electronic platforms made that arbitrariness untenable. As Keith puts it, "price transparency almost by definition means reduction in margin," and that reduction sat at the heart of the cultural battle that followed. The arrival of the multi-dealer platforms forced banks to confront a proposition many found offensive, that they might pay a commission to compete for their own clients. He recounts the reaction of one senior figure, Phil Weisberg at JP Morgan, to an early pitch for such a model: "You mean you're going to charge me to price my clients in competition with other banks? Get out of here." That the same institution was quietly working on FXall at the time tells its own story about how quickly the idea moved from heresy to orthodoxy.

"If the same client had asked two salesmen for an identical price, they would get two different prices, because the salesman's job was to read the client and judge the appropriate margin for that size of trade on that occasion.”

...CONTINUED

The division ran straight through the trading floor, separating electronic sales from voice sales, the channel that had traditionally carried the margin. Keith does not pretend the hostility was trivial. On occasion, he suspected some banks would have been glad to see the very platforms they had backed fail. He singles out those who saw past the conflict early, such as a manager who equalised sales credits regardless of channel, removing the incentive to fight over how a trade was booked.

From Single-Dealer to Multi-Dealer and Back Again

Keith's vantage point makes him an unusually credible guide to the shape of the market today, because he watched the pendulum swing in both directions. The early technology driver was the single-dealer platform, with banks competing on the most feature-rich, computationally heavy applications as a form of brand marketing. The multi-dealer platforms then rose on a clear client demand to compare prices and execute quickly. What he describes now is a considered return.

"There's a temptation just to hit the best price, and sooner or later you run into a massive concentration of credit.”

"From single dealer platform to multi dealer platform and back to single dealer platform, with execution styles that lend themselves to the particular type of trade being done. That's where we are now."The reasons are practical rather than fashionable. Pure price competition has costs that only became visible with experience. "There's a temptation just to hit the best price," Keith notes, "and sooner or later you run into a massive concentration of credit." The development of algos and of independent pre-trade and post-trade TCA gave clients a viable alternative to simply putting five banks in competition, particularly for large or sensitive orders where the market's reaction to a price request can work against them. He points to the most recent BIS triennial survey as support for the trend, and to the next, then due in December, as a likely confirmation of it.

Why Judgment and Relationships Persist as Markets Digitise

For a man who spent a decade selling the technology that compressed the salesman's margin, Keith is notably firm that the salesperson does not disappear. Price transparency may be total, but clients need more than price. The salesperson remains the bridge into the wider resources of the bank, whether that is research, technology, or the credit line that a pure best-price model can quietly overconcentrate.This is also where his observations on interface design land. The early systems, he recalls, were built with an expert user in mind. "Over the last fifteen years or so it's been about making interfaces that are much easier to use. You don't need to be a quant or a trader to use this thing." The same instinct that once made adoption depend on specialist knowledge now works in the opposite direction, consolidating the seven different screens a second-tier salesperson might otherwise juggle into a single place where credit lines, exposure and past trades sit together.His advice to anyone entering the market reflects that conviction. "Take time to understand the business and understand the clients. What are they using the product for? Where are they going? What are their fears?" It is, in the end, a people business, and the tools are only as good as the understanding behind them.

Adapting Through Change

"There are still some salespeople who refer to electronic trading as the toy. Guys, get a grip. This is here to stay.”

FINAL THOUGHTS

Keith describes himself as having arrived slightly after the AI wave, content to leave that chapter to the next generation. Yet the discipline he returns to throughout is exactly the one that period will demand: a willingness to move toward change rather than away from it, paired with the humility to keep asking questions. He has little patience for the residual instinct that still treats electronic trading as a novelty."There are still some salespeople who refer to electronic trading as the toy. Guys, get a grip. This is here to stay."

Across four decades, the firms, the platforms and the pricing models have all changed, often more than once. What has held constant is the value of understanding the business deeply, treating it as a people business, and approaching each shift with a plan rather than a reaction. For an industry now contemplating its next wave of automation, that may be the most durable lesson of all.
