Katsuyama describes a reinforcing cycle in which scandal prompts regulation, imperfect regulation creates loopholes and inefficiencies, participants exploit those openings, and extreme exploitation produces the next scandal. Each round adds complexity and raises the cost of entering the industry. The paradox is that the firms associated with the scandals may remain protected as regulatory walls rise around them, while potential disruptors face greater barriers. The model is both diagnostic and strategic. Trace today's exploit back through the rule and scandal that shaped it, insist on accountability, then look for a market design that removes the exploit's payoff without waiting for another rule change. IEX represents Katsuyama's proposed interruption: a voluntary venue built within existing regulation to correct structural weaknesses through different mechanics.
Origin
Katsuyama used the model to explain a century of recurring Wall Street scandals and why IEX pursued a market-based response rather than asking first for new regulation.
Core principles
- 01No rule is perfect
- 02New rules create loopholes and unintended consequences
- 03Profitable loopholes attract exploitation
- 04Exploitation produces the next scandal and another regulatory layer
- 05Accumulated regulation raises entry barriers and protects incumbents
- 06Market-based alternatives can interrupt the cycle
How to run it
- 1
Trace the triggering scandal
Identify the failure that produced the current regulatory response. Record the behavior the rule was intended to prevent.
Pro tip Distinguish the public justification from the operational requirement that was enacted.
Watch out Starting with the present rule hides why its compromises exist.
- 2
Map loopholes and inefficiencies
Examine where the rule is incomplete, ambiguous, or costly. Show how those gaps alter participant behavior.
Pro tip Look for legal behavior that reproduces the harm in a technically different form.
Watch out No rule should be assumed perfect because its intent is sound.
- 3
Follow the incentives
Identify which actors gain concentrated benefits from exploiting each gap and who bears the distributed costs. Estimate how exploitation could scale.
Pro tip Follow both the money earned and the infrastructure spending required to earn it.
Watch out Diffuse harm may remain politically quiet even when its aggregate cost is large.
- 4
Measure the barrier effect
Assess how accumulated compliance complexity affects prospective entrants relative to incumbent firms. Determine whether another rule would raise the same walls further.
Pro tip Separate the cost of responsible operation from complexity that chiefly protects scale.
Watch out A regulation can punish future competitors more than the actors that caused the scandal.
- 5
Design a structural alternative
Create a product, venue, or market mechanism that removes the exploit's payoff while remaining within the current rules. Make the improved behavior a property of the system.
Pro tip Seek voluntary adoption from participants who benefit from a more trusted market.
Watch out A new entrant can reproduce the cycle if its incentives eventually match the incumbents'.
- 6
Maintain accountability
Require participants and institutions to own factual claims and conduct. Use accountability to keep the alternative from becoming another opaque layer.
Pro tip Pair transparent rules with observable execution behavior.
Watch out Without recourse for false claims, the market cannot reliably improve.
In the wild
Rather than requesting a rule change, IEX created a venue whose mechanics reduced the value of latency advantages. Katsuyama presents it as an outside disruption to exchanges that had incentives to keep selling speed, data, and colocation.
→ Participants received a voluntary alternative intended to correct a structural weakness within existing regulation.
Common mistakes
Assuming the next rule ends the cycle
Every rule has gaps and unintended effects. Without incentive analysis, another layer can create the next opportunity for exploitation.
Ignoring barriers to disruption
Accumulated regulation makes entry harder. That can leave the actors associated with prior scandals more deeply entrenched.
Replacing accountability with complexity
Katsuyama argues that markets improve when people own what they say and do. More rules do not substitute for that recourse.
Is it for you?
Best for
It is best for reformers and entrants analyzing a mature regulated industry after repeated scandals and compliance expansions.
Not ideal for
It is not ideal as an excuse to avoid necessary enforcement or accountability for conduct that directly violates existing rules.
From the transcript
“You have a scandal, it's followed by regulation. There's no such thing as a perfect rule. That regulation will create loopholes and inefficiencies consequences.”
“And as as regulation increases, it raises the barriers to entry for disruption.”
“I X is a free market solution. Um, it's our choice, and we're trying to correct inefficiencies. We're trying to patch up the loopholes.”
