Rogue Trading at Lloyds Bank International, 1974: Operational Risk in Volatile Markets

By Catherine Schenk (Glasgow)

Abstract Rogue trading has been a persistent feature of international financial markets over the past thirty years, but there is remarkably little historical treatment of this phenomenon. To begin to fill this gap, evidence from company and official archives is used to expose the anatomy of a rogue trading scandal at Lloyds Bank International in 1974. The rush to internationalize, the conflict between rules and norms, and the failure of internal and external checks all contributed to the largest single loss of any British bank to that time. The analysis highlights the dangers of inconsistent norms and rules even when personal financial gain is not the main motive for fraud, and shows the important links between operational and market risk. This scandal had an important role in alerting the Bank of England and U.K. Treasury to gaps in prudential supervision at the end of the Bretton Woods pegged exchange-rate system.

Review by Adrian E. Tschoegl (The Wharton School of the University of Pennsylvania)

Since the 1974 rogue trading scandal at Lloyds’s Lugano branch we have seen more spectacular sums lost in rogue trading scandals. What Dr Catherine Schenk brings to our understanding of these recurrent events is the insight that only drawing on archives, both at Lloyds and at the Bank of England, can bring. In particular, the archives illuminate the decision processes at both institutions as the crisis unfolded. I have little to add to her thorough exposition of the detail so below I will limit myself to imprecise generalities.

Marc Colombo, the rogue trader at Lloyds Lugano, was a peripheral individual in a peripheral product line, in a peripheral location. As Schenk finds, this peripherality has two consequences, the rogue trader’s quest for respect, and the problem of supervision. Lloyds Lugano is not an anomaly. An examination of several other cases (e.g. Allied Irish, Barings, Daiwa, and Sumitomo Trading), finds the same thing (Tschoegl 2004).

In firms, respect and power come from being a revenue center. Being a cost center is the worst position, but being a profit center with a mandate to do very little is not much better. The rogue traders that have garnered the most attention, in large part because of the scale of their losses were not malevolent. They wanted to be valued. They were able to get away with their trading for long enough to do serious damage because of a lack of supervision, a lack that existed because of the traders’ peripherality.

In several cases, Colombo’s amongst them, the trader was head of essentially a one-person operation that was independent of the rest of the local organization. That meant that the trader’s immediate local supervisor had little or no experience with trading. Heads of branches in a commercial bank come from commercial banking, especially commercial lending. Commercial lending is a slow feedback environment (it may take a long time for a bad decision to manifest itself), and so uses a system of multiple approvals. Trading is a fast feedback environment. The two environments draw different personality types and have quite different procedures, with the trading environment giving traders a great deal of autonomy within set parameters, an issue Schenk addresses and that we will discuss shortly.

Commonly, traders will report to a remote head of trading and to the local branch manager, with the primary line being to the head of trading, and the secondary line being to the local branch manager. This matrix management developed to address the problem of the need to manage and coordinate centrally but also respond locally, but matrix management has its limitations too. As Mathew points out in the New Testament, “No man can serve two masters, for either he will hate the one, and love the other; or else he will hold to the one, and despise the other” (Matthew (6:24). Even short of this, the issue that can arise, as it did at Lloyds Luggano, is that the trader is remote from both managers, one because of distance (and often time zone), and the other because of unfamiliarity with the product line. A number of software developments have improved the situation since 1974, but as some recent scandals have shown, they are fallible. Furthermore, the issue still remains that at some point the heads of many product lines will report to someone who rose in a different product line, which brings up the spectre of “too complex to manage”.

The issue of precautionary or governance rules, and their non-enforcement, is a clear theme in Schenk’s paper. Like the problem of supervision, this too is an issue where one can only do better or worse, but not solve. All rules have their cost. The largest may be an opportunity cost. Governance rules exist to reduce variance, but that means the price of reducing bad outcomes is the lower occurrence of good outcomes. While it is true, as one of Schenk’s interviewees points out, that one does not hear of successful rogue traders being fired, that does not mean that firms do not respond negatively to success. I happened to be working for SBCI, an investment banking arm of Swiss Bank Corporation (SBC), at the time of SBC’s acquisition in 1992 of O’Connor Partners, a Chicago-based derivatives trading house. I had the opportunity to speak with O’Conner’s head of training when O’Connor stationed a team of traders at SBCI in Tokyo. He said that the firm examined too large wins as intently as they examined too large losses: in either case an unexpectedly large outcome meant that either the firm had mis-modelled the trade, or the trader had gone outside their limits. Furthermore, what they looked for in traders was the ability to walk away from a losing bet.

But even small costs can be a problem for a small operation. When I started to work for Security Pacific National Bank in 1976, my supervisor explained my employment benefits to me. I was authorized two weeks of paid leave per annum. When I asked if I could split up the time he replied that Federal Reserve regulations required that the two weeks be continuous so that someone would have to fill in for the absent employee. Even though most of the major rogue trading scandals arose and collapsed within a calendar year, the shadow of the future might well have discouraged the traders, or led them to reveal the problem earlier. Still, for a one-person operation, management might (and in some rogue trading scandals did), take the position that finding someone to fill in and bring them in on temporary duty was unnecessarily cumbersome and expensive. After all, the trader to be replaced was a dedicated, conscientious employee, witness his willingness to forego any vacation.

Lastly, there is the issue of Chesterton’s Paradox (Chesterton 1929). When a rule has been in place for some time, there may be no one who remembers why it is there. Reformers will point out that the rule or practice is inconvenient or costly, and that it has never in living memory had any visible effect. But as Chesterton puts it, “This paradox rests on the most elementary common sense. The gate or fence did not grow there. It was not set up by somnambulists who built it in their sleep. It is highly improbable that it was put there by escaped lunatics who were for some reason loose in the street. Some person had some reason for thinking it would be a good thing for somebody. And until we know what the reason was, we really cannot judge whether the reason was reasonable.”

Finally, an issue one needs to keep in mind in deciding how much to expend on prevention is that speculative trading is a zero-sum activity. A well-diversified shareholder who owns both the employer of the rogue trader and the employers of their counterparties suffers little loss. The losses to Lloyds Lugano were gains to, inter alia, Crédit Lyonnais.

There is leakage. Some of the gainers are privately held hedge funds and the like. Traders at the counterparties receive bonuses not for skill but merely for taking the opposite side of the incompetent rogue trader’s orders. Lastly, shareholders of the rogue traders firm suffer deadweight losses of bankruptcy when the firm, such as Barings, goes bankrupt. Still, as Krawiec (2000) points out, for regulators the social benefit of preventing losses to rogue traders may not exceed the cost. To the degree that costs matter to managers, but not shareholders, managers should bear the costs via reduced salaries.

Historicising Business Strategy

Evolving Ideas about Business Strategy

by Pankaj Ghemawat (NYU Stern, USA and IESE Business School, Spain)


This paper updates an earlier article published in Business History Review that concluded that by the second half of the 1990s, there had been a profusion of new, purportedly practical ideas about strategy, many of which embodied some explicit dynamics. This update provides several indications of a drop-off since then in the rate of development of new ideas about strategy but also a continued focus, in the new ideas that are being developed, on dynamics. And since our stock of dynamic frameworks has, based on one enumeration, more than doubled in the last fifteen to twenty years, updating expands both the need and the empirical basis for some generalizations about the types of dynamic strategy frameworks—and strategy frameworks in general—that managers are likely to find helpful versus those that they are not.

Review by Kyle Bruce (Macquarie University, Australia)

Editor’s note

Ghemawat’s 2017 paper below should not be read in isolation but as part of a round table organized at Harvard Business School that brought together historians and management scholars to discuss the origins of ideas in business and management. The results of the round table were published as a special edition of the Business History Review. In this sense, Ghemawat’s contribution to the special issue and its discussion by Chris McKenna (in the same special issue) came to an independent yet similar conclusion to that expressed by Nobel laureate Robert Shiller, who suggested “that in the age of social information networks, economists need to rethink how and why information really spreads.” (See a summary of Shiller’s ideas in The Role of Narratives in Economics).

It is laudable that the executive editors of the Business History Review created a space to disseminate the results of the round table through the journal. However, as you will read below, Kyle Bruce questions whether this is the right way to engage other management scholars in business history as, strictly speaking, the contribution by Ghemawat would be found wanting as scholarly work of international standing.

A final note is that in its comments to Ghemawat, even McKenna gets it wrong by pointing to Lotus 1-2-3 as the first spreadsheet. It actually was VisiCalc.

Having said that, the aim in this space is to generate academic debate through a blog format. So by all means do chip in.

As a historian and teacher of strategy and, moreover, as a close follower of Ghemawat’s work, I was very much looking forward to his recent update of his 2002 BHR paper on the history of the sub-discipline. I habitually invoke the decade-and-a-half old piece as background reading for my Executive MBA strategy students and hitherto have experienced little, if any, pushback from students typically cagey about the words “theory” or “history”. Regrettably, I am not so sure the updated paper under review here will escape unscathed for the simple reason that it is pretty tough to follow. Let me explain.

After briefly overviewing the 2002 paper that in essence discerned a profusion of new ideas about strategy – particularly those embodying a more dynamic approach – dating from the early to mid-80s, Ghemawat introduces his new findings. After a big peak in the mid-90s, there has been a marked drop-off in new ideas, but dynamics “is a sustained interest focus of strategic innovation rather than one of passing interest” (p. 5; emphasis added). So far, so good you might think, but I started to worry about the phraseology (“strategic innovation”?) attendant on the use of analytical tools from strategy and adjacent sub-disciplines to make sense of his findings; namely, “what should one make of the drop-off overall and the shift toward more attention to dynamics? And what, if anything, should be done?” (p. 8).

Unless the strictures concerning the dreaded “so what?” question have been lifted in history journals such as BHR, I could not discern after several reads a compelling argument as to why readers should be at all bothered by the findings presented? For students of the strategy-as-practice literature, for instance, the suggestion there’s fewer models and frameworks out there for practising managers to employ is not a concern given they probably don’t use them anyway. For my MBA students who routinely complain of framework fatigue, again, the theory drop-off is not a problem. And so, for me, the remainder of the paper was rather superfluous and unnecessarily complex. Curiously, I think Ghemawat makes it so when he concludes that while it’s certain there’s been a drop-off in the “rate of development of big new strategy ideas/frameworks, it is much harder to be definite about the welfare implications” (p. 10; emphasis added). For me, this conclusion renders redundant both the ensuing “what is to be done” question he poses, as well as the next eight-and-half pages of the article devoted to “a critical assessment of frameworks new and old” (p. 2).

After several reads of these aforementioned pages, I could not really follow or appreciate the “irreversibility” and “uncertainty” dimensions utilised to assess how dynamic current frameworks really are. However, I felt comforted when Ghemawat concludes that “quite a few” of said frameworks “seem subject to some practical limitations” (p. 19). This comfort was short-lived, though, when he finishes the paper with the frustrating and seemingly throwaway line that the way forward, as it were, “is to shift some attention away from the chronologies of frameworks to historiography that attempts to assess them in some fashion” (p. 21). I immediately asked myself: “well, why didn’t he just do this, then??”


For me, and I trust also BHR readers, a historiographical piece embodying intellectual history, actor-network theory, or sociology of scientific knowledge to account for the “trials of strength” in strategy theory, the tension between contributions from the academy and those from business practice, and the current fascination with dynamics, would have been an easier and more interesting read. Like much being published in business and management history journals of late, Ghemawat’s paper is short on actual history and, notwithstanding the final sentence, even short on how to DO history. I was left wondering why this paper was published in this journal and asking myself what this paper’s place tells me about BHR? I have no answers for these questions but look forward to some in due course.

Keynes and Actual Investment Decisions in Practice

Keynes and Wall Street

By David Chambers (Judge Business School, Cambridge University) and Ali Kabiri (University of Buckingham)

Abstract: This article examines in detail how John Maynard Keynes approached investing in the U.S. stock market on behalf of his Cambridge College after the 1929 Wall Street Crash. We exploit the considerable archival material documenting his portfolio holdings, his correspondence with investment advisors, and his two visits to the United States in the 1930s. While he displayed an enthusiasm for investing in common stocks, he was equally attracted to preferred stocks. His U.S. stock picks reflected his detailed analysis of company fundamentals and a pronounced value approach. Already in this period, therefore, it is possible to see the origins of some of the investment techniques adopted by professional investors in the latter half of the twentieth century.

This short article looks at Keynes’ purchases of US securities in the period from after the Wall Street Crash until World War II. The investments the authors discuss are not Keynes’ personal investments but are those relating to the discretionary fund (the ‘Fund’) which formed part of the King’s College, Cambridge endowment fund and which was managed by Keynes. The authors rely for their analysis on previously unused archival material: the annual portfolio holdings of the endowment fund; the annual report on discretionary fund performance provided by Keynes to the endowment fund trustees; correspondence between Keynes and investment experts; and details of two visits by Keynes to the US in 1931 and 1934.


The authors look at various aspects of the investments in US securities made by Keynes. They first note the high proportion of equities in the endowment fund as a whole. They then focus in detail on the US holdings which averaged 33% by value of the Fund during the 1930s. They find that Keynes invested heavily in preferred stock, which he believed had suffered relatively more than ordinary shares in the Wall Street Crash and, in particular, where the preference dividends were in arrears. He concentrated on particular sectors – investment trusts, utilities and gold mining – which were all trading at discounts to underlying value, either to do with the amount of leverage or with the price of gold. He also made some limited attempts at timing the market with purchases and sales, though the available archival data for this is limited. The remainder of the paper explores the type of investment advice Keynes sought from brokers, and from those finance specialists and politicians he met on his US visits. The authors conclude that he used outside advice to supplement his own views and that, for the Fund, as far as investment in US securities was concerned, he acted as a long-term investor, making targeted, value investments rather than ‘following the herd’.

This paper adds a small element to an area of research which is as yet in its infancy: the analysis of actual investment decision making in practice, and the evolution of investment strategies over time. In terms of strategies, Keynes used both value investing and, to a lesser extent, market timing for the Fund. Keynes was influenced by Lawrence Smith’s 1925 book which recommended equity investment over bond investment on the basis of total returns (dividends plus retained earnings) rather than just dividend yield, the then common equity valuation method. Keynes appears not to have known Benjamin Graham but came to the same conclusion – namely that, post Wall Street Crash, value investing would lead to outperformance. He experimented with market timing in his own personal portfolio but only to a limited extent in the Fund. He was thus an active investor tilting his portfolio away from the market, by ignoring both US and UK railway and banks securities. Another fascinating aspect which is only touched on in this paper is the quality of investment advice at the time. How does it stack up compared to current broker research?


The paper highlights the fact that issues which are still not settled today were already a concern before WWII. Should you buy the market or try to outperform? What is the appropriate benchmark portfolio against which to judge an active strategy? How should performance be reported to the client (in this case the trustees) and how often? How can one decide how much outperformance comes from the asset allocation choice of shares over bonds, from the choice of a particular sector, at a particular time, whilst making allowance for forced cash outflows or sales such as occurred during WWII? More research on how these issues were addressed in the past will better inform the current debate.
