Insurance

Its role in the system

Insurers take on the risks of people and companies — fire, accident, illness, death, natural disaster — in exchange for a small regular payment, the premium. They invest the premiums they collect for years, so insurance both shields the economy from sudden losses and ranks among its largest long-term investors, above all in bonds.

Functions

1. Risk transfer — thousands of customers pay premiums into a common pool, and the few who suffer a loss are paid out of it; without this, people and businesses would have to sit on huge reserves just in case.
2. Life insurance — payouts to a family on death, savings-linked policies, annuities (income for life); by its nature this is long-term saving.
3. Non-life insurance — property, motor, liability, health, marine, aviation, cyber; some lines are compulsory, notably motor third-party liability (🇪🇺 the Motor Insurance Directive and the international Green Card system).
4. Reinsurance — insurance for insurers: large and catastrophic risks are shared among global reinsurers (Munich Re, Swiss Re, Hannover Re) and with the capital markets through catastrophe bonds.
5. Investing — premiums arrive now and claims are paid years later; insurers invest that float mostly in government and corporate bonds.
6. Distribution — brokers (Marsh, Aon, WTW) design insurance programmes for companies and place the risks in the market; agents, online platforms and banks (bancassurance) sell policies to individuals.

What makes it special

• How it earns, and why the price comes before the cost: income is the underwriting result (premiums minus claims and expenses — the key measure is the combined ratio, where below one hundred percent means the insurance itself is profitable) plus investment income on the float. The twist is that the price of the policy is set before the cost is known: how much the claims will come to only becomes clear years later. That is why technical reserves are the heart of the company, and why underestimating future payouts is the central risk.
• Who regulates: 🇪🇺 Solvency II (in force since 2016, with a revised version from 2027: risk-based capital, risk management, disclosure) and EIOPA; 🇺🇸 state regulators, coordinated by the NAIC; 🇬🇧 the PRA and the FCA. Global standards come from 🌍 the IAIS; contract accounting follows IFRS 17, in force since 2023. 🇪🇺 Since August 2022 an intermediary must ask the client whether they have sustainability preferences — but only after establishing their needs and capacity to pay, so preferences cannot override whether the product suits the client.
• How it differs from a bank: an insurer's liabilities are long and mostly predictable, so a run by customers is a rarer threat. It is vulnerable instead to catastrophes, to errors in reserving, and — in life insurance — to a long stretch of low interest rates.
• Newer formats: 🇬🇧 Lloyd's of London, a market of syndicates for complex risks from ships to satellites; InsurTech — digital insurers and parametric policies that pay out automatically on a trigger, such as the measured strength of an earthquake; and smart-contract cover in decentralised finance, still niche and unregulated.
• 🇨🇳 China: the biggest insurers, on a capital regime of their own: Ping An and China Life are among the world's five largest insurers by assets, and their capital adequacy is measured under the national C-ROSS regime: its second phase has applied since the start of 2022 under NFRA supervision and rests on the same three pillars as European Solvency II — risk-based capital, risk management requirements, disclosure. A vast market, then, but one living by its own rulebook rather than Europe's.
• 🇯🇵 Japan: insurance sold through the post office, and the lesson of negative spread: one of the largest life insurers is Japan Post Insurance (Kampo), which sells policies through the postal branch network and belongs to the Japan Post holding. Only from the financial year ended 31 March 2026 did the FSA move the industry off a 1997-vintage solvency rule onto an economic valuation of liabilities (ESR). Why it matters is written in Japan's own history: after the bubble burst, investment returns fell below the returns promised in old policies — negative spread — and between 1997 and 2001 five life insurers went under, the first of them Nissan Mutual Life.

Why it matters

Without insurance, mortgages and secured loans are not written, ships do not sail and factories do not get built: nobody takes a risk where a single fire or storm means bankruptcy. When an insurer gets its sums wrong, the losses land on its customers — or on the state.

• Anti-Money LaunderingInsurance is exposed to laundering through savings policies, early surrenders and reinsurance, so it reports to Anti-Money Laundering on the same footing as banks.
• Audit & AssuranceThe key number for Insurance is the reserve for future claims, and that is exactly what Audit & Assurance tests together with an actuary under IFRS 17.
• Banking & Credit InstitutionsInsurance reaches clients through Banking & Credit Institutions: bancassurance sells policies at the branch, and cover on the collateral is a condition of a mortgage or a secured loan.
• Commodities marketMarine cargo and hull cover from Insurance is a condition of every oil or grain shipment: without a policy the goods are not loaded and no bank opens a letter of credit for the Commodities market.
• Corporations & Corporate FinanceInsurance covers Corporations & Corporate Finance against property, liability, cargo and cyber losses, and brokers assemble whole programmes for large groups.
• Debt marketInsurance is among the biggest buyers of long bonds in the Debt market: long liabilities are matched with long assets.
• DerivativesInsurance hedges the interest rate and currency risk of its portfolio with Derivatives and passes catastrophe risk to investors through catastrophe bonds.
• Education & CertificationThe actuary is a profession with a compulsory qualification: without years of exams from Education & Certification nobody may sign off on the adequacy of Insurance reserves.
• Households & IndividualsInsurance sells Households & Individuals life, health, motor and home cover, and third-party motor liability is compulsory.
• Investment & Pension FundsInsurance and Investment & Pension Funds compete for the same long-term household money: both collect contributions and invest them, but the insurer promises a payout on an event and the fund promises only what the assets are worth.
• Monetary PolicyInsurance is one of the largest holders of bonds, so every turn of rates in Monetary Policy revalues insurers' portfolios; and a long spell of very low rates makes old guaranteed-return policies loss-making — the negative-spread problem.
• Ratings & IndicesThe financial strength rating from Ratings & Indices decides whether corporate clients and reinsurers will deal with an Insurance company at all.
• Real estate marketInsurance invests its long reserves in the Real estate market — offices, warehouses, rental housing — and in mortgage loans, because those assets match the maturity of its liabilities.
• Regulation & SupervisionInsurance operates under Regulation & Supervision: licence, capital and reserve requirements, and oversight of sales and client protection.
• State Insurance & GuaranteesThe state takes on risks the market cannot carry, such as terrorism and war, and State Insurance & Guarantees often shares them with private Insurance.
• Technology & InfrastructureInsurance runs on its own class of systems from Technology & Infrastructure: policy and reserve ledgers, actuarial engines, and in InsurTech parametric covers where the payout is triggered by recorded event data rather than a claim form.
