Who regulates a Luxembourg life insurer? The role of the Insurance Commission

The Insurance Commission (CAA) oversees Luxembourg life insurers. It is a public institution, and its primary mission is to protect policyholders. It monitors the insurer's financial situation, tracks the inventory of assets representing its liabilities, approves the deposit agreement with the custodian bank, and can freeze these assets if the insurer's financial stability is questioned. It also handles complaints from individuals free of charge. This oversight focuses on the insurer itself. It does not affect the performance of your unit-linked funds.

Who is the CAA?

The CAA is a public institution with legal personality and financial autonomy. The amended law of December 7, 2015, on the insurance sector sets its primary objective as ensuring the protection of policyholders. It entrusts it with the supervision, including financial supervision, of insurance companies.

The CAA publishes a coordinated version of this law, updated to 03/04/2026. This is an informational text: only the Official Gazette is authoritative.

What the CAA is actually monitoring

The CAA's 2025-2026 annual report outlines the elements of the policyholder protection system. The report covers the year 2025 up to July 1, 2026.

The report cites CAA regulation no. 16/01 of 03/05/2016, which mandates deposit with an EEA credit institution. The precise role of the depositary bank is detailed on a dedicated page.

The blocking is the key point to remember: the report describes it as a simple instruction from the CAA to the depositary, triggered if the financial soundness of the company is called into question.

The rules for investing in unit-linked contracts

The CAA also regulates what the insurer can hold. Its regulation no. 15/03 of 07/12/2015, in its coordinated version of 27/01/2023, notably sets out two rules:

• the insurer invests in assets whose risks can be identified, measured, monitored, managed, controlled and reported (art. 53(1)); ;
• where benefits are linked to the value of units of a UCITS or assets of an internal fund, technical provisions are represented as closely as possible by those units or, failing units, by those assets (Art. 53(2)(a)).

A more recent version of the regulations is possible. The exact list of assets eligible for inclusion in a unit-linked contract is detailed on another page.

The CAA and insurers who sell in France

The CAA is the authority for the country of origin of Luxembourg insurers. Its "Life" technical committee monitors life insurers operating under the freedom to provide services (FPS) or freedom of establishment. For branches of companies from the European Economic Area (EEA) established in Luxembourg, the CAA is limited to collecting statistical information on their activity (annual report, p. 20).

Two definitions from the ACPR, the French authority, help to understand these terms. In the direction "towards France":

• Freedom of establishment allows an insurer authorized in one EEA state to provide services in another state through a permanent entity, a branch; ;
• The freedom to provide services allows services to be provided in another state without a permanent establishment.

The ACPR also specifies that distributors from another EEA state operating in France are subject to French general interest rules, in a list it describes as indicative. This list notably includes customer information, intermediary remuneration, and conflicts of interest.

Complain to the CAA

The CAA handles complaints from individuals against professionals under its supervision, including insurance companies, free of charge. The following time limits apply:

• You first sent a written complaint to the insurer; ;
• She remained without a satisfactory response for 90 days; ;
• You must contact the CAA within one year of this claim.

You can write in Luxembourgish, German, French, or English. The CAA is seeking an amicable solution. Its conclusions are not binding.

What the control does not cover

The CAA's oversight focuses on the insurer and protecting your rights in case of default. It does not eliminate market risk. In a unit-linked contract, the investment risk is borne exclusively by the policyholder, and the contract does not include any guarantee of return from the insurer (CAA circular letter 26/1, dated 01/02/2026).

Numerical example (fictitious profile)

Situation. A fictitious policyholder holds a Luxembourg contract. On 15/01/2026, he writes to the insurer to contest the processing of a partial redemption request.

Issue. The insurer's response does not resolve the disagreement. The policyholder does not know when they can appeal to the CAA, nor until what date.

Strategy. Begin by submitting a written claim to the insurer, keeping a record of the sending date. Wait 90 days without a satisfactory response. Then, file a claim with the CAA within one year of the claim.

Result. The 90-day period ends on April 15, 2026. The year following the claim ends on January 15, 2027. The policyholder therefore has 275 days to file a claim with the CAA. The procedure is free of charge, and its conclusions are not binding on the insurer.

CALCULATION: 15/01/2026 + 90 days = 15/04/2026; 15/01/2026 + 1 year = 15/01/2027; 15/01/2027 − 15/04/2026 = 275 days. The CAA page does not specify how the 90 days are counted: the calculation uses calendar days, for illustrative purposes. The date of 15/01/2026 is a hypothetical scenario.

What changes depending on your situation

• The moment of the dispute. The 90-day period and the one-year period start from the written claim: the date counts.
• The type of contract. Whether the fund is dedicated or not, and the date of issue of the contract, the investment rules are not the same.
• The sales method. A Luxembourg insurer can operate in France through freedom to provide services or via a branch.
• The nature of the problem. A disagreement with the insurer and a loss of value due to the markets do not fall under the same legal recourse.

These points are examined on a case-by-case basis. No result is guaranteed in advance.
