Luxembourg life insurance: what the law protects, and what it does not protect

A Luxembourg life insurance contract is governed by a specific protection regime. The Insurance Commission (CAA) oversees the insurer. The assets representing your rights are held in custodianship, separate from those of the insurer, and protected by a lien. This protection covers the insurer's default. It does not cover a decrease in the value of your unit-linked funds: this risk remains yours.

Four elements, one objective

The term "safety triangle" does not appear in the CAA documents. The CAA describes the system by its components. Here they are, in the order in which they come into play.

CAA control

The CAA is a public institution. It has legal personality and financial autonomy. Its primary mission is the protection of policyholders. It supervises the insurance companies it approves, including their financial practices.

The reference text is the amended law of 7 December 2015 on the insurance sector. The CAA publishes a consolidated version, updated to 03/04/2026.

The custodian

The insurer does not hold the securities representing its commitments itself. It deposits them with a credit institution, generally located in the European Economic Area (EEA).

The CAA oversees this filing:

• the deposit agreement is subject to his approval; ;
• the assets must be clearly separated from the other assets of the company, without any possibility of offsetting; ;
• the depositary shall immediately provide the CAA, upon request, with any information; ;
• he warns him without delay and on his own initiative of any blocking or enforcement measure that does not originate from the CAA; ;
• he complies with the blocking instructions; ;
• Liquidity remaining outside the deposit agreement is capped at 5 % of technical provisions.

Separation of assets

The CAA states in its FAQ on FWU: in Luxembourg, policyholders' assets are separate from those of the insurance company. The insurer's assets and yours are not mixed.

The privilege, or "super-privilege"«

Luxembourg law defines an insurance claim. It is any amount owed by an insurance company to its insureds, policyholders, beneficiaries or victims who have a direct right of action.

The deposited assets are assigned a privileged position to the payment of these debts. According to the model deposit agreement published by the CAA, once the assets are entered in the permanent inventory, this privilege "takes precedence over all others".

In its FAQ on FWU, the CAA uses the term "super-lien." It specifies that both lessees and beneficiaries benefit from it. Its other documents refer to it as a "lien" or a "privileged claim." The CAA's model agreement places this lien before other liens, once the assets are recorded in the permanent inventory.

A public case: FWU Life Insurance Lux

The mechanism was implemented on a real case, documented by the CAA.

• July 19, 2024: CAA press release on the insolvency of FWU Life Insurance Lux SA. It reports the freezing of representative securities held by custodian institutions. The text dates the freezing decision to July 23, 2024.
• January 31, 2025: Judgment of liquidation and dissolution of the company. The CAA document announcing this is dated February 3, 2025.

The CAA background note specifies that the assets representing the liabilities were deposited with custodian banks under a tripartite deposit agreement. They were separate from the insurer's own assets. Policyholders and beneficiaries had a preferential claim right.

This page does not provide any information on the amount recovered by each saver. The sources consulted do not allow us to say.

What is not protected

The mechanism protects against the insurer's failure. It does not protect against the market.

• The investment risk is on you. In a unit-linked contract, the risk is borne exclusively by the policyholder. The insurer makes no guarantee of return.
• The dedicated fund has a separate regime. For a dedicated fund, the policyholder only has the privilege common to all insured parties. The assets remain the property of the insurer. This point is stated in the contract before signing.
• French ceilings do not apply by analogy. In France, bank deposits are covered up to €100,000 per depositor per institution, and securities up to €70,000 per client per institution. These figures concern accounts and securities. They do not describe the protection offered by a Luxembourg contract.

A recent rule establishes the framework for unit-linked contracts. CAA Circular Letter 26/1, dated February 1, 2026, applies to contracts issued from that date onward. Existing contracts remain governed by their previous rules, including Circular Letter 15/3 of March 24, 2015. Regarding the common privilege of dedicated funds, both texts state the same thing.

A depositary outside the EEA: change effective 01/02/2026

Circular letter 26/2 of 01/02/2026 amends circular 16/9 on custodians. For a custodian located outside the EEA, the choice of this custodian is presumed essential to the conclusion of the contract, subject to cumulative conditions:

• the subscriber falls under categories A to D of circular 26/1; ;
• The general terms and conditions place the risk associated with the custodian on the lessee; ;
• the lessee participated in the appointment of the custodian, or was informed of it and accepts it; ;
• the scope is limited to certain funds; ;
• A special declaration, signed by the policyholder and the insurer, is attached to the contract.

The effective date is not indicated in the text. If your contract involves a custodian outside the EEA, read this declaration before signing.

Numerical example (fictitious profile)

Situation. A fictitious couple invests €500,000 in a Luxembourg contract invested entirely in unit-linked funds.

Issue. He believes that "the contract is protected" and equates this protection with the value of his capital.

Strategy. Let's separate two questions. First: what happens if the insurer defaults? The answers lie in the CAA's oversight, the custodian, asset segregation, and the lien. Second: what happens if the markets fall? Here, no compensation mechanism exists. The contract's composition and the type of fund (dedicated or not) should be read with this distinction in mind.

Result. With a 20% decrease in the unit value, assumed for analysis purposes and not as a forecast, the value falls from €500,000 to €400,000. The €100,000 difference is borne by the lessee, even though the asset separation is functioning exactly as planned.

CALCULATION: 500,000 × 20 % = 100,000; 500,000 − 100,000 = 400,000. The €500,000 and the 20 % are assumptions of the fictitious profile.

What changes depending on your situation

• The type of contract. Dedicated fund or not: the privilege is not the same.
• The date of issue. Contracts issued since 01/02/2026 fall under circular 26/1.
• The custodian. Within the EEA or outside the EEA: the conditions differ.
• Your horizon and your tolerance for downward pressure. They have a greater impact on the final outcome than the legal framework.

None of these situations can be resolved by a general rule. They must be examined on a case-by-case basis.
