Podcast: LSE: Public Lectures and Events
Session Time: 15:00
Date: July 14, 2010
Host: LSE Film and Audio Team
Speaker: John Kay (with additional participants during Q&A)

Overview

In this episode, John Kay delivers a thought-provoking analysis on the necessity of structural reform in the financial services industry, focusing on the dual themes of competition and systemic risk. He also explores the cultural differences within financial institutions, the failures highlighted by the 2007-08 financial crisis, and draws instructive analogies from other industries. The session concludes with an engaging Q&A, touching on Glass-Steagall-type reforms and the relevance of network theories.

Key Discussion Points & Insights

1. Reasons for Structural Reform

[00:06 – 04:00]

• Competition:
  • Financial markets should foster competition between specialist, diversified institutions.
• Systemic Risk:
  • Structural reform is needed to address "too big to fail."
  • Promoting robustness and resilience through functional separation.
• Convergence of Motives:
  • Although competition and systemic risk involve distinct arguments, “they point in essentially the same direction” in today’s environment.
• Cultural Incompatibility:
  • Contrasting the entrepreneurial, risk-taking culture of investment banking with the bureaucratic, accuracy-focused culture of retail banking.
  • Quote:

    “Investment banking requires people who are entrepreneurial, buccaneering, highly intelligent, typically very arrogant, typically very greedy as well... The corporate culture required for retail banking is essentially bureaucratic... honest and unimaginative people who will process millions of transactions every day with a very high degree of accuracy.”
    [01:58 – 03:05]

2. Historical Context and Lessons from Past Failures

[04:00 – 07:50]

• Big Bang (1986) and its aftermath:
  • UK retail banks’ acquisition of wholesale institutions ended disastrously, revealing deep cultural misalignment.
• Rise of American Investment Banks in London:
  • British and European banks mimicked US investment banks, embedding ongoing tensions.
• Consequences:
  • Investment banking personalities disproportionately influenced policy, regardless of overall value added.

3. The 2007-08 Crisis and Misconceptions around Separation

[07:50 – 10:00]

• Retrospective Fragility:
  • Irony in how risk was transferred, not eliminated, within institutions.
  • Quote:

    “The very diversity of the financial institutions that failed... is perhaps the best illustration... of the inherent fragility of the financial system that we have today.”
    [10:13]

• Lesson from Lehman:
  • The goal isn't to prevent organizational failure, but to ensure failure doesn't destabilize the entire system.
  • Quote:

    “Lehman going bust is not an example of a failure of capitalism. Lehman going bust is an example of capitalism operating as capitalism is supposed to work... What we need is an environment in which an organization like Lehman can go bust without it damaging the rest of the economy.”
    [09:20 – 09:55]

4. Analogies to Other Complex Systems

[10:00 – 13:38]

• Lessons from Electrical Engineering:
  • Engineers prevent minor failures from causing system-wide collapse through “modularity, redundancy, and diversity.”
  • These system design concepts should be applied to financial architecture, not just regulatory organization.
• Utility vs. Casino Metaphor:
  • Payment systems resemble utilities that must never be disrupted, while trading/investment banking is akin to casinos where risk can occur.
  • Expands metaphor to three categories:
    1. Network Utilities (e.g., railways, water): Require uninterrupted function, insulated against failure.
    2. Essential Commodities (e.g., food, fuel, credit): Normally market-based but government-intervened in crisis.
    3. General Commodities (“casino” finance): Provided as markets dictate, no utility-style guarantees.

5. Structural vs. Behavioral Regulation

[14:30 – 19:45]

• UK Banking's Structural Stasis:
  • Minimal change in retail banking landscape over the 20th century—indicative of complacent oligopoly aided by regulatory barriers.
• Behavioral Regulation's Limits:
  • Intensively detailed supervision entrenches incumbents—regulation mirrors established firms’ practices.
  • Quote:

    “Behavioral regulation... is a form of regulation that massively favors the positions of incumbent firms... ratcheted up by orders of magnitude by creating this doctrine of too big to fail.”
    [17:16 – 17:45]

• Call for Structural Reform:
  • Cites the need for “competition where possible, regulation only where necessary” and structural solutions over behavioral ones.
  • Warns that failure to act could undermine capitalism itself.
  • Quote:

    "If we are not willing to handle these issues in a more effective way, then we risk further crises that are potentially the end not just of the financial system as we know it, but of the capitalist settlement that we have all enjoyed since 1989."
    [22:43 – 23:08]

Q&A Highlights

Q1: Glass-Steagall and Structural Separation in the UK

[23:22 – 25:50]

• Question: Should the UK re-implement Glass-Steagall style separation, and reconsider “single capacity” at the Stock Exchange?
• Kay’s Response:
  • Supports the general direction, especially distinct separation between retail and wholesale (investment) banking—not copycat Glass-Steagall but in that spirit.
  • Suggests exploring functional separation within investment banking itself due to inherent conflicts.
  • Focus should be on smaller, more functionally distinct institutions to enhance resilience.
  • Quote:

    “The central move which needs to be made... is to create a distinction between the kind of retail banking activities... and the wholesale market activities... Other groups of functional separation should be considered as well...”
    [24:45 – 25:50]

Q2: Should Financial Reform Focus on Network Thinking?

[26:21 – 29:17]

• Question: Alan Diplock (NZ Securities Commission):
  Advocates “network solutions” and learning from other sciences (epidemiology, genetics, internet architecture), citing Andy Haldane’s work.
• Kay’s Response:
  • Finds the network metaphor compelling, especially the vulnerability of complex systems (e.g., electricity grids) to small disruptions.
  • Warns that a single-network solution could inadvertently lead to de facto nationalization, which he sees as suboptimal.
  • Emphasizes the importance of learning from regulatory successes and failures in other industries, not assuming finance is unique.
  • Quote:

    "We need to stop thinking about the problems of financial services as being entirely sui generis and understand that there are lessons to be learned from the structure of other industries and from regulatory successes and failures in other industries..."
    [29:07 – 29:52]

Notable Quotes

• On Culture:

  "Investment banking requires people who are entrepreneurial... very arrogant, typically very greedy as well... The corporate culture required for retail banking is essentially bureaucratic..."
  [01:58 – 03:05]

• On Systemic Risk:

  "What we need is not an environment which will ensure that Lehman will not go bust... We need an environment in which an organization like Lehman can go bust without it damaging the rest of the economy."
  [09:20 – 09:55]

• On Regulatory Capture:

  "Behavioral regulation... is a form of regulation that massively favors the positions of incumbent firms in the industry..."
  [17:16 – 17:45]

• On the Stakes:

  "We risk further crises that are potentially the end not just of the financial system as we know it, but of the capitalist settlement that we have all enjoyed since 1989."
  [22:43 – 23:08]

Memorable Moments

• Personal Reflection:
  Kay humorously suggests he might have ended up a middle manager at RBS if he hadn’t passed his school exams—offering a personal perspective on banking careers.
  [03:15]
• Systemic Irony:
  The episode is held at the Institution of Electrical Engineers, a field with relevant expertise on the resilience of complex networks—a key metaphor throughout Kay’s talk.

Conclusion

John Kay’s lecture delivers a thorough and nuanced critique of the state of modern finance, warning that without radical, structural reforms, both systemic vulnerability and regulatory inertia threaten not just the financial sector, but the broader capitalist order. Advocating for competition, functional separation, and openness to lessons from other industries, Kay’s arguments are reinforced and challenged through thoughtful audience questions that extend the discussion into contemporary network theory and comparative regulation.
