Solvency Regulation

Study guides: Exam 6C, Exam 6U, Exam GI-201

Solvency Regulation is supervision aimed at ensuring an insurer can pay claims as they come due — capital requirements, valuation standards, reserve adequacy, and intervention when they are breached. In Canada it is OSFI's federal mandate (and the province's for provincially chartered insurers), and it is distinct from market conduct and rate regulation.

$\text{Solvent} \iff \text{Assets} \ge \text{Liabilities} + \text{Required Capital}$

The three pillars, following the international pattern that Solvency II made explicit: quantitative requirements (MCT, valuation of Insurance Contract Liabilities), supervisory review (ORSA, FCT, on-site examination, the Appointed Actuary's reports), and disclosure (the Canadian Annual Return, public financial statements).
Canadian solvency regulation is risk-based: required capital scales with the insurer's actual risk profile — insurance, market, credit and operational risk, less a diversification credit — rather than being a flat percentage of premium.
It is deliberately not zero-failure. OSFI's mandate requires it to let insurers compete and take reasonable risks; the residual failures are handled by PACICC. A regime with no failures would have set capital requirements so high that insurance became unaffordable.
Early intervention is the design goal. The ladder of internal target, supervisory target and minimum capital ratio (Supervisory Target Capital Ratio, Internal Target Capital Ratio) exists so that action begins while the insurer still has surplus to work with, not at the point of insolvency.
Solvency and rate regulation can conflict: a regulator suppressing rates for affordability weakens the insurers it also supervises for solvency. Canada's split — provinces price, OSFI capitalises — means neither body owns both sides of that trade-off.

Rate Suppression Meets Solvency Supervision A province holds auto rate increases to $2\%$ for three years while claims costs rise $8\%$ per year. Trace the consequences through the solvency framework.

Answer Year by year the gap compounds: after three years, prices are roughly $1.02^3 = 1.061$ times the base while costs are $1.08^3 = 1.260$ times — a shortfall of about $16\%$ of premium.

The chain of effects:

Underwriting losses erode capital, lowering the MCT ratio through a smaller numerator.

Reserve strengthening as the inadequacy becomes visible in development, lowering it again.

Volume contraction as insurers restrict writing in the province — which relieves the capital strain but creates an availability problem, pushing risks into the Facility Association and residual market.

If the FCT report's adverse scenarios show the ratio falling below the supervisory target, OSFI escalates — but OSFI cannot fix the cause, because it does not set rates.

This is the structural tension in Canadian regulation, and it is the reason auto reform is usually about benefits rather than prices: reducing what the product costs is the only lever that reconciles affordability with solvency.
