Principles-based regulation is failing investors

The promise of principles-based regulation in Canada was a smarter alternative to thick rulebooks — flexible, modern, focused on outcomes. The result, two decades on, is less protection for investors, weaker enforcement and more discretion for firms.

The original logic was not unreasonable. Instead of a prescriptive rulebook, regulators would articulate high-level expectations — act with integrity, treat clients fairly and manage conflicts of interest. Firms would then decide how to meet those standards. Flexibility replaces rules. Judgment replaces checklists.

But the promise collapses when regulators are unwilling to challenge how firms use their discretion. Without that supervision, a principle becomes elastic language that firms can bend, rationalize and defend.

The U.K. learned that lesson the hard way. Its Financial Services Authority (FSA) was an early champion of principles-based regulation, formally committing to the approach by 2007.

The case was straightforward: detailed rules invite gaming. Firms find the gaps. Principles speak to the spirit of regulation and leave fewer gaps to exploit.

The Great Financial Crisis showed what principles without active supervision produce: deference. Firms enjoyed flexibility. Regulators relied too heavily on professional judgment.

Northern Rock, a British mortgage lender that became one of the first major casualties of the crisis, was an early warning. The FSA’s Turner Review called for a fundamental rethink.

The FSA abandoned light-touch supervision and was later broken apart. Its conduct successor kept principles-based regulation but paired it with more intensive supervision. Its prudential successor moved further toward prescription.

Half the lesson

Canada watched and learned only half the lesson. It copied the flexible, firm-friendly features of the model. It did not copy the supervisory muscle the U.K. learned it needed.

Principles-based frameworks have since become the preferred model across Canadian financial regulation. The Canadian Securities Administrators (CSA) have embedded principles throughout their conduct standards. The Canadian Investment Regulatory Organization’s (CIRO) rules lean heavily on fair dealing, suitability and conflict management. Industry got the framework it wanted, and no one with standing pushed back.

The framework recently faced an important test — a joint CSA and CIRO review of how firms had adopted the client-focused reforms. It failed.

The regulators reviewed 105 firms four years after the reforms took effect. They found that many had not fully implemented them and responded mainly with more guidance — a response that exposed the impotence of the principles-based approach.

Principles have their place. They adapt more easily to new products, new platforms and new business models. That is why industry likes them. It is also why they require more intensive supervision than Canada has been willing to apply.

You can see it in the language regulators use. Read their guidance and the grammar gives the game away.

When the subject is firms, the verbs are concrete and indicative: burdens are reduced, flexibility is granted, supervision is lightened for cooperative behaviour.

When the subject is investors, the verbs go soft — interests the regulator strives to reflect, outcomes it hopes to encourage.

One side is told what it will receive. The other is told what to wish for. That is not a drafting accident. It is a tell.

That tell shows up in large scale non-compliance. Investors pay first through weaker enforcement. Proving misconduct under an elastic standard like “treat clients fairly” is harder than enforcing a clear rule. Repeated failures produce another staff notice and another round of guidance. The market hears the message: non-compliance will be managed, not punished.

Investors pay again when supervision becomes a review of process rather than outcomes. Did the firm have a conflict-of-interest policy? Did advisors complete required training? Did supervisors sign off? These are process questions.

Whether investors were protected is another matter. Principles-based frameworks excel at generating documentation. They are much less reliable at showing the investor was better off.

They pay a third time through uncertainty. Rules give investors a baseline they can understand. Principles give them a standard to interpret. A rule capping a charge at 1% is a number an investor can check. A principle requiring a fee to be reasonable is a dispute the investor must win.

And ultimately, they pay when something goes wrong. A dispute under a principle is fought in the language of professional judgment. Firms speak that language fluently. Consumers usually do not. The consumer brings the story. The firm brings the policy, the interpretation and the compliance file.

That mismatch is what the framework produces.

The answer is not a thicker rulebook. Prescription gets stale and firms comply with the letter while ignoring the spirit.

Principles cannot do everything. Fees, compensation conflicts, proprietary shelves and complex retail products are known risks. Where harms like these are foreseeable, the rule should be clear in advance — not interpreted after the fact.

Where principles remain, they need supervision intensive enough to test whether firms are actually delivering the outcomes regulators purport to attain. Without it, principles-based regulation is discretion dressed up as investor protection.

Canada took the model. It is time to take the lesson: prescription where outcomes can be measured, principles where they cannot and supervision strong enough to test both.
