Principles-Based Regulation

Study guide: Exam 6C

Principles-Based Regulation sets the outcomes a regulated firm must achieve and holds its board and senior management accountable for achieving them, rather than prescribing the rules by which they must do so. It is the dominant Canadian approach: OSFI's ORSA, FCT, Corporate Governance and reinsurance expectations all state what must be achieved and leave the method to the insurer.

The contrast with rules-based regulation:
- Rules-based — prescribed formulas, fixed limits, a compliance checklist. Predictable, comparable, cheap to supervise, hard to evade in the specifics.
- Principles-based — stated outcomes, insurer-designed methods, supervisory judgement. Adapts to different business models and to innovation, and cannot be gamed by satisfying the letter of a rule.
The Canadian framework uses both, deliberately. The MCT is rules-based — a prescribed formula producing a comparable ratio — while ORSA sits on top of it asking whether the formula is enough for this insurer. Neither alone would work: pure rules miss firm-specific risk, pure principles produce numbers nobody can compare.
Advantages: proportionate to the firm; robust to product innovation, since a new product still has to meet the outcome; and it makes evasion harder, because satisfying a rule technically while defeating its purpose is itself a failure.
Disadvantages: less predictable, since firms cannot be certain what will satisfy the supervisor; more expensive, since each firm builds its own approach; harder to enforce, because a breach is a judgement rather than a fact; and it depends on supervisory capacity and consistency.
It shifts work to the actuary. Under a prescribed margin, the actuary applies it; under a principles-based standard the actuary must select, justify and document — which is why IFRS 17's entity-specific risk adjustment with a disclosed confidence level replaced prescribed MfADs.
Solvency II is the international expression of the same philosophy: three pillars of quantitative requirements, supervisory review and disclosure, with internal models permitted subject to approval.

Which Approach for Which Problem? A regulator wants to address three concerns. For each, decide whether a rule or a principle is the better instrument.

Ensuring insurers hold enough capital to be comparable across the industry.

Ensuring insurers manage climate-related risk.

Ensuring an insurer does not concentrate its reinsurance with a single counterparty.

Answer

A rule. Comparability is the objective, and comparability requires a common formula. The MCT is rules-based for exactly this reason: a regulator, an analyst and a rating agency must all be able to read one insurer's ratio against another's. A principles-based capital requirement would produce numbers that could not be compared at all.

A principle. Climate risk manifests differently for a coastal property insurer, an auto insurer and a commercial liability writer, and the science and the exposure are both changing. A prescribed climate capital charge would be obsolete on issue and wrong for most firms. OSFI's B-15 accordingly requires governance, scenario analysis and disclosure — outcomes — rather than a formula.

Both, and this is the instructive case. A principle — the insurer must manage reinsurance counterparty risk within its stated appetite — is the right instrument, because the appropriate concentration depends on the counterparty's strength, the collateral held and the insurer's own capital. But experience shows that pure principles here produce drift, so a backstop rule (registration requirements, collateral rules for unregistered cessions, and the credit risk charge) sets a floor beneath the judgement.

The general rule that emerges: use rules where comparability or a hard floor is the objective; use principles where the right answer is firm-specific or the subject matter is changing faster than rules can be written. Canada's framework is a deliberate mixture, and describing it as one or the other misses the design.
