I have just published a new article on FinoLib, my free finance education library: Solvency II and Risk-Based Capital: Insurance Solvency Rules. It is part of Volume III: Finance Encyclopedia. Below is a summary of the topic in plain, expert language, so you can follow the idea even before you open the full article.
The idea in plain words
Insurers must hold capital to survive bad scenarios, and the rules differ by place. The EU’s Solvency II requires capital at the 99.5% one-year Value-at-Risk of own funds. The US uses a factor-based system with action levels from 200% down to 70%. India requires a 150% solvency ratio. A separate standard, IFRS 17, governs when insurance profit is reported.
Key points
■Solvency II values liabilities as a best estimate plus a risk margin, discounted at risk-free rates, and adds the ORSA under Pillar 2.
■The MCR sits between 25% and 45% of the SCR; a breach of the SCR requires a recovery plan within two months.
■US RBC ratio = total adjusted capital ÷ Authorized Control Level RBC; below 200% the insurer must file a plan, below 70% the regulator must take control.
■IFRS 17’s contractual service margin releases profit over the coverage period and recognizes losses at once.
A closer look
Insurance regulators require insurers to hold sufficient capital to remain solvent even under adverse scenarios, using a risk-based framework directly analogous to Basel’s bank capital requirements (Volume I’s Part 3). The EU’s Solvency II framework is the most comprehensive global example: it requires insurers to calculate a Solvency Capital Requirement (SCR) — the capital needed to withstand a 1-in-200-year adverse event — and a lower Minimum Capital Requirement (MCR), below which regulatory intervention becomes severe and immediate.
A worked example
Worked Example — A Solvency II Balance Sheet and Its Coverage Ratio
An insurer ($ millions) holds assets of 10,000. Its best estimate of liabilities is 8,600 and its risk margin 200, so technical provisions are 8,800. Other liabilities are 300 and subordinated debt 100. Excess of assets over liabilities = 10,000 − 8,800 − 300 − 100 = 800. Basic own funds = 800 + 100 of qualifying subordinated debt = 900. With an SCR of 600, the SCR coverage ratio = 900 ÷ 600 = 150%. The MCR must lie between 25% × 600 = 150 and 45% × 600 = 270. Now let rates rise.
Under the hood
Under the Hood: IFRS 17 — How Insurance Profit Is Reported
Capital rules decide whether an insurer can pay; accounting rules decide when it reports profit. IFRS 17, effective for annual periods beginning on or after January 1, 2023, measures each group of contracts as fulfillment cash flows (spelled “fulfilment” in the standard): the present value of future cash flows on current assumptions plus a risk adjustment for non-financial risk. To these it adds a contractual service margin (CSM), the unearned profit. The CSM is released to profit as coverage is provided, so a profitable 20-year policy reports its profit over 20 years rather than at sale; if a group of contracts is or becomes loss-making, the loss is recognized immediately.
Decision rule
Read every solvency ratio against its own trigger, then against its own sensitivity. Under Solvency II, 100% SCR coverage is the legal line, and a board sets its own target above it as a buffer; under US RBC, 200% of ACL RBC is the first action line; under IRDAI, 150% is the control level.
The costliest mistake
Comparing solvency ratios across regimes, or across bases, as if they were the same number. A US insurer with total adjusted capital of $500 million and ACL RBC of $200 million has an RBC ratio of $500m ÷ $200m = 250%. Measured against the Company Action Level ($400 million, twice ACL), the same capital is $500m ÷ $400m = 125%. The same capital can be quoted as 250% or 125% depending on the denominator.
Recap
Solvency II requires own funds covering a Solvency Capital Requirement set at the 99.5% one-year Value-at-Risk, with an MCR beneath it and an ORSA alongside; US states apply NAIC risk-based capital action levels from 200% down to 70% of Authorized Control Level; India requires a 150% solvency ratio. These ratios measure different things, and IFRS 17, through the contractual service margin, governs when insurance profit appears in the accounts.
