What if understanding regulation could help us spot when politicians are promising the impossible? Regulation sounds simple in theory. Something poses a risk, so we create rules and a regulator to control it. In practice, things get complicated very quickly. It's something we all benefit from, but equally can experience as redtape that prevents us from doing what we think we ought to be able to.
On this episode, I'm exploring the inner workings of regulation; so whether you are a regulator, a compliance officer, work in a regulated industry or just a member of the public, this'll help you understand what is and isn't possible and why regulation can often seem ineffective or overbearing.
Episode summary My guests on this episode are Lyndon Nelson and Gavin Stewart, two highly experienced former financial regulators and authors of Building Better Regulators: The Art of the Impossible.
Regulators are expected to protect consumers, maintain stability, encourage competition, support innovation and increasingly promote economic growth. The problem is that those objectives don't always point in the same direction. As Lyndon and Gavin explain, making trade-offs is part of regulation; pretending those trade-offs don't exist is where things become problematic.
In our conversation, we explore the tension between rules and principles, why firms don't always respond to regulation in the way regulators expect, and how enforcement involves choices about which cases not to pursue. We also look at regulatory perimeters, the hidden costs of collecting data, and why having more information doesn't necessarily lead to better regulation.
We also discuss AI and crypto, behavioural science, consumer protection, international regulation, the temptation to fight the last war, and why regulators need imagination as well as analysis. Ultimately, this is a conversation about regulation as a human system — shaped by incentives, politics, judgement, uncertainty and the behaviour of both regulators and the regulated.
Guest bios Lyndon Nelson spent 33 years at the Bank of England, much of it working in regulation, and ultimately became Deputy CEO of the Prudential Regulation Authority (PRA). Since leaving the Bank, he has worked with organisations including London Business School and the International Monetary Fund.
Gavin Stewart began his career as a banking supervisor at the Bank of England before moving to the Financial Services Authority (FSA), where he held a variety of senior roles. He later became Chief Risk Officer at the Financial Conduct Authority (FCA) and subsequently worked in the private sector.Together, they are the authors of Building Better Regulators: The Art of the Impossible, a book designed to help regulators — and those who interact with them — better understand the practical realities of regulation.
